MARSXpress Disposable Liners are to be used in MARSXpress 55 mL and 75 mL vessels for

applications where the temperature does not exceed 180 °C and total run time is less

than 30 minutes.

It is important to preform the opening of the disposable liner to ensure proper fit and sealing

of the plug and cap. These instructions are for use of 55 mL and 75 mL disposable Teflon®

liners in MARSXpress vessels. In addition to the disposable liners you will need the Flaring

Tool and Insertion Tool.

1. Take one liner and place the open end over the tip of the Flaring Tool.
