1.0 Introduction

The Harris e-Core is a compact, versatile, electric coring device designed for unrestricted sampling

of a wide range of DNA storage products or other sample substrates. The Harris e-Core was created

to bridge the gap between the lower cost, manual Harris Micro-Punch and Harris Uni-Core and the

automated bench top punching platforms. The ergonomic “joy stick” grip and the e-Core’s simple

operation provide comfort and efciency, integrating smoothly into all levels of laboratory sample

throughput. The user has complete management of the disc recovery process, the coring speed and

disc delivery.

The Harris e-Core, like the Harris Micro-Punch and Harris Uni-Core, continues to offer the same

unique combination of patented simultaneous sampling features: coring, retrieving and storing in

a single operation, but with dramatically increased processing times. The Harris e-Core ejection

system, like its predecessors, still offers the user the ability to control both the speed and delivery

of the ejected disc. Most importantly the Harris e-Core ejection system does not generate static,

affecting both accuracy and precision. The manually controlled ejection system and lack of static

generated ensures accurate disc delivery.

The Harris e-Core is a coring tool and not a punch. The Harris e-Core has been designed to utilize

dedicated replaceable Harris Micro-Punch Tips. The razor sharp cutting edge on the Harris Micro-

Punch Tip cleanly and precisely cores discs from substrates, all but eliminating the creation of

artefacts and potential cross contamination between sampling.

The Harris e-Core is currently available in three models identied by their respective industry standard

coring diameters: 1.2 mm, 2.0 mm and 3.0 mm. Each model has a xed diameter plunger ejection

rod ensuring efcient sample ejection. The Harris e-Core utilizes Harris Micro-Punch Tips which

conveniently thread to the Harris e-Core drive shaft. Each tip is made from 304 stainless steel with a

nitride coating and Rockwell Hardness of Rc60. The ejection rod is made from 304 stainless steel.

2.1 Harris e-Core Body

The Harris e-Core body has an ergonomic “joy-stick” conguration.

The body is moulded from a nylon/berglass composite offering a smooth, non-stick nish.

The Harris e-Core has:

1. A Finger rest for easy gripping,

2. A motor activation button (red) for coring,

3. A plunger ejection rod button (black) for disc recovery and placement into a

collection vessel such as a microfuge tube or multi-well plate,

4. A safety ange at its base for hand support and protection and

5. A threaded drive shaft by which the Harris Micro-Punch Tip attaches to the Harris e-Core.

Please note: The Harris e-Core plunger and tips are dedicated to their respective models

and are not interchangeable between different models.

2.2 Harris Micro-Punch Tips

The Harris Micro-Punch Tips are manufactured from

304 stainless steel bar, nitride coated and heat treated to

Rockwell Hardness 60 (Rc60). Each tip is hand sharpened

to a ne edge delivering approximately 1500 to 2000 sample

discs from FTA cards.

The optimum coring cycle (i.e. the length of time the tip

rotates in contact with an FTA card surface) for a new tip

ranges from 1 to 1.5 seconds. As the tip cutting edge dulls

with use the coring cycle will increase as the user attempts to extend the cutting life of the tip.

The coring cycle must be monitored. When the coring cycle noticeably increases above 3

seconds, the Harris Micro-Punch Tip must be replaced. If you continue to operate the Harris

e-Core at coring cycles above 3 seconds you will be putting strain on the motor thereby

shortening its rated operating life. Each Harris e-Core is sold with two extra Harris Micro-Punch

Tips to maximize throughput and functionality.

The tip cover cap is made from poly ethylene plastic. The cover cap must be placed on the cutting

tip when the Harris e-Core is not in use. This will protect the tip from incidental contact, which

could damage the cutting edge, and from user injury through contact with the cutting edge.

All Harris Micro-Punch Tips are sold with a protective cover cap. The cap must be placed on the old

tip prior to replacement and remain on the new tip when replacing tips on the Harris e-Core. The

Harris e-Core MUST NOT BE PLUGGED IN WHEN CHANGING TIPS. Harris Micro-Punch Tips

are not sold sterilized.

2.3 Optional Cord Wrist Strap

The optional cord wrist strap allows the operator

the option of restricting the movement (rotation)

of the DC jack in the pin at the top of the Harris

e-Core. The wrist strap positions the cord

extending from the DC jack along the operator’s

hand to their wrist and forearm, thereby keeping

excess cord from the work area. The power

cord is loosely strapped along the wrist and

forearm using the velcro wrist strap, providing

a less congested working area. The image on

the far right shows the cord tucked between the

palm of the hand and the Harris e-Core without

the use of the writst strap. There are many

ways to manage the cord during operation.

When using the wrist strap the operator must remember to unstrap the velcro band from the wrist to free the

excess cord when the e-Core is no longer in use. If this is not performed the operator may pull the unit and power

supply from the work surface, possibly damaging the unit and causing injury to themselves and others.

2.4 International Multi-Plug Set

The e-Core is provided with four international plug sets allowing worldwide use depending

on your geographic location. The plug sets are designated as follows NA - North America, EU -

Europe, Aust. - Austrailia and UK - United Kingdom. Select the plug for your geographic location

and insert as per instructions in Section 6.0. The plug may only be inserted in one direction to

the power supply. You will hear the plug snap into place which means it is rmly seated.

Although the plugs are interchangeable on the power supply, the process of unseating an

existing plug set can be difcult due to the design of the system which ensures the plug

is rmly seated in the power supply to ensure good contact and not to loosen with use.

Consequently it may be difcult to remove and exchange plugs but this is explained further in

Section 6.0. Therefore please take time to choose the correct plug for your geographic location.

2.5 Power Supply

The e-Core power supply is provided by FranMar with the

following specications: Input: AC 100-240V-0.7A 50-60Hz.

Output 24V - 1.0A

AUST

2.6 Harris Cutting Mat

The Harris Cutting Mat provides the best possible cutting

surface for the Harris e-Core Tips. The mat is made of

polyvinyl chloride, an inert, self-healing material. The mat

offers a second cutting service on its reverse side. The

cutting mat can be used several hundred times. In order to

prevent cross contamination the Harris Cutting Mat may be

cleaned as described in Section 4.0.

2.7 Harris e-Core Carrying Case

The moulded plastic case provides a safe protective storage place for the Harris e-Core when not

in use. The case holds all Harris e-Core components.

3.2 Harris e-Core and Sample Preparation

3.2.1 First time users insert the correct international plug set (NA,

UK, AUST or EU) into the power supply. See section 6.0.

3.2.2 Set up the work area. For use with an FTA card, place card

on top of Harris Cutting Mat.

3.2.3 With the e-core unplugged and the cover cap on the tip,

make sure the Harris Micro-Punch tip is “nger tight” on the drive

shaft of the e-Core by rmly holding the knurled surface of the drive

shaft in the ngers of one hand and tightening the tip in a clockwise

motion with the ngers of the other hand. The tip may loosen with

prolonged coring and may need periodic nger tightening.

3.2.4 Remove protective cover cap from Harris Micro-Punch Tip

by gripping the knurled surface of the drive shaft with one hand and

gently removing the cover cap off the tip with a rocking motion.

3.2.5 You may now plug in the Harris e-Core

3.3 Harris e-Core Operation

3.3.2 With the free hand hold FTA card down and in contact with

cutting mat. This is required as the card may spin when the Harris

e-Core cutting tip makes contact with the card. Also there is a

need to hold down the card when lifting the e-Core tip from the

cored card, stripping the card off the tip. KEEP FREE HAND AND

FINGERS AWAY FROM TARGET AREA.

3.3.3 The Harris e-Core is held above the FTA card in the vertical

position with the Harris Micro-Punch Tip perpendicular to the FTA

card target surface area.

3.3.4 Depress the red Activation Button (left side) with thumb to

begin the rotation process before making contact with the sample

surface. Lower tip until contact is made with the FTA card sample

surface. The tip is very sharp and minimal downward pressure

is needed to pass through the FTA card, making contact with the

Harris Cutting Mat below. Note: The Harris e-Core is a rotary tool.

The motor is activated by depressing the Activation Button (red

button) causing the razor sharp cutting tip to rotate. Rotation stops

immediately upon release of the Activation Button.

Depress the red Activation Button engaging the Harris e-Core

motor for 1 – 1.5 seconds to core the disc. Contact must be made

with the Harris Cutting Mat below the sample (card) to urge the disc

into the lumen of the Harris Micro-Punch Tip. The most efcient

and complete coring action is achieved only when the entire surface

edge of the Harris Micro-Punch Tip is in uniform contact with the

substrate surface. This will ensure that the downward pressure is

uniformly applied to the entire blade/sample surface interface.

3.3.1 Grip Harris e-Core unit in either hand. Use wrist strap to

optionally position excess cord along wrist (far left) or position cord

as shown in the illustration on the immediate left to keep cord out

of sampling zone.

NOTE: New users will require a brief period to acquaint themselves with the operating system and

the ease and speed with which a disc can be cored with the Harris e-Core. Coring with a new tip

should take 1 to 1.5 seconds to complete. In a very short period of time the user will become familiar

with recognizing when the coring edge on the tip has passed through the sample and made contact

with the underlying Harris Cutting Mat, urging the disc into the lumen of the Harris e-Core tip.

As the Harris Micro-Punch Tip makes contact with the sample and then Harris Cutting Mat below, the

speed of rotation may drop due to the resistance the Harris Cutting Mat places on the Harris Micro-

Punch Tip edge. Do not keep the Harris Micro-Punch Tip in contact with the Harris Cutting Mat

longer than the prescribed 1 – 1.5 seconds. Prolonged contact will put a strain on the motor and

dull the tip faster. If the user nds it necessary to keep the Harris e-Core tip in contact with the FTA

card longer than 1.5 seconds to cut a disc, than the tip is dull and must be replaced.

The optimum coring cycle (i.e. the length of time the tip rotates in contact with an FTA card) for a

new tip ranges from 1 to 1.5 seconds. As the tip cutting edge dulls with use the coring cycle will

increase. The coring cycle must be monitored. When the coring cycle noticeably increases

above 3 seconds, the Harris Micro-Punch Tip must be replaced. If you continue to operate the

Harris e-Core at coring cycles above 3 seconds you will be putting strain on the motor thereby

shortening its rated operating life. Each Harris e-Core is sold with extra Harris Micro-Punch Tips

to maximize throughput and functionality.

3.3.5 With the Activation Button still depressed lift the e-Core

vertically away from the sample surface while still holding the FTA

card rmly with the other hand on the cutting mat. This will allow the

Harris e-Core tip to be stripped away from the FTA card. Once clear

of the card surface remove thumb from Activation Button stopping

rotation. Once the disc has been cored it is simultaneously retrieved

into the Harris Micro-Punch Tip lumen where it may be temporarily

stored. The disc will not dislodge from the lumen until ready for

ejection. The lumen in the Harris Micro-Punch Tip functions as

temporary storage allowing the operator to rest the Harris e-Core,

if necessary, on its side on the bench to address disc delivery. The

disc will not fall out of the tip lumen.

3.3.6 Core and eject a single disc at one time. Do not core and

collect more than one disc in the tip lumen and then eject all cored

discs from lumen. Collecting two or more discs in the lumen before

ejecting may clog the lumen preventing ejection or may damage the

plunger ejection rod during the ejection operation.

3.3.7 Use only the Harris Micro-Punch Tip size corresponding to the Harris e-Core model listed

in the Table under Section 1.0. The use of other Harris Micro-Punch Tips on a non-corresponding

Harris e-Core model and plunger ejection rod diameter may result in damage to the plunger ejection

rod mechanism and/or incomplete sample ejection delivery. Therefore, for example, use only a

1.2mm Harris Micro-Punch Tip with the Harris e-Core 12. Do not use a 2.0 mm Harris Micro-Punch

Tip on the Harris e-Core 12 and vice versa. Each Harris e-Core unit is sold with a plunger ejection

rod with a specic outside diameter for use with a designated coring tip inside diameter. This ensures

complete sample ejection and delivery. Although the Harris e-Core threaded Drive Shaft will accept

other diameter Harris Micro-Punch Tips used in different Harris e-Core models, a smaller diameter

plunger ejection rod may not be capable of ejecting larger diameter discs cored with larger diameter

Harris Micro-Punch Tips.

3.4 Sample Ejection and Clean Up

3.4.1 Position the Harris Micro-Punch Tip over the desired collection

area or sample holder (i.e. microfuge, test tube, multiwell plate,

etc.). Using the thumb depress the black Ejection Button (right side)

at top. Make sure the disc drops into the receptacle and does not

adhere to the side of the receptacle. There is no static generated

from the Harris e-Core during the coring or the ejection process.

The low rpm and short coring cycle do not contribute static, but

there may still be ambient static due to dry conditions or climate.

Therefore, as a precaution, we suggest the user monitor disc delivery.

3.4.2 Follow the cleaning instructions for the Harris Micro-Punch Tip and Harris Cutting Mat in

Section 4.0 to clean instruments between sampling.

3.4.3 When nished coring unplug the e-Core, place the cover cap on the tip and return

the unit to storage case.

4.0 Cleaning

The Harris e-Core cuts rather than shears or tears samples from substrates. This coring/cutting

action eliminates the creation of artefacts and possible cross contamination between collected and

ejected discs. To further prevent cross-contamination between samples, you may clean the cutting

edge of the Harris Micro-Punch Tip between each coring operation. Dip the cutting edge into a 2%

solution of sodium hypochlorite (NaClO) and press the plunger up and down a few times. After

rinsing, wipe the tip and plunger with a clean paper towel. The Harris Cutting Mat may also be wiped

down with 2% sodium hypochlorite solution after each sampling.

5.0 Tip Replacement

5.1 With the Harris e-Core unplugged and with the protective cover cap in place over the Harris

Micro-Punch Tip, remove the tip from the e-Core by gripping the knurled surface on the e-Core drive

shaft to keep the shaft from rotating while unscrewing the tip.

5.2 Thread a new Harris Micro-Punch Tip, covered with a protective cap, onto the drive shaft of the

Harris e-Core. Make sure the tip is attached “nger tight” only. Keep protective cover cap over the

new tip until you are ready to use the Harris e-Core.

6.0 Plug Replacement

6.1 Changing a plug set on the power supply can be difcult. The plug/power supply system is

designed to rmly hold the plug set in the power supply sleeve to ensure a permanent connection

without loosening. To replace a plug set depress the release button (1) with the thumb of one hand

while simultaneously pushing against the posts of the plug set with the other hand (see left image).

It is recommended that you place some barrier such as paper towel or other soft material between

your hand and the posts (right image) as this will assist with unseating and pushing the plug set out

of the power supply sleeve while protecting your hand.

6.2 To insert a plug into the power supply slide the open end of the plug into the slot on the power

supply and continue to push until you hear it snap into place. This ensures the plug is rmly seated

with a good connection.
