Teledyne ISCO SyriXus Syringe Pump Safety Note When Using a Flammable Fluid
The Teledyne ISCO syringe pumps must be placed within a properly operating vent hood (fume cup-
board), when using any flammable liquid at elevated temperatures, or ethane or any other flam-
mable gas. Ensure that all fluid handling connections are completely free of any gas leaks by
performing the leak test using CO
Verification Procedures
nical-bulletins). There must absolutely be NO gas leaks present before introducing the flammable
vapor. The flow rate, as registered by the pump, should settle to a value below 0.01 mL/min after 15
minutes during a static extraction in a temperature stable, leak-free system.
Important: When using flammable fluids with the Teledyne ISCO SyriXus syringe
pumps, ensure that proper safety precautions are followed, and that adequate ventilation
is always provided around the pump.
The Teledyne ISCO SyriXus syringe pumps use brush-type drive motors. Minor modifications to the
pumps may render them safer, especially in the rare event of catastrophic piston seal failure.
However, these modifications will not make these pumps explosion proof.
Remove the front and back cylinder covers located on the ball screw tower. This will allow any
escaped gas to quickly dissipate away from the pump cylinder area and to reduce the amount
entering the motor compartment.
Seal the syringe pump motor compartment with tape and purge the pump lower cabinet with a con-
tinuous flow of nitrogen (N
mixture around the motor and relays.

information in Section 9.3 "Customer Service Department".
ATTENTION: Teledyne ISCO does not recommend or support the use of the SyriXus
syringe pumps with any flammable gas.
