Teledyne Isco SFX System and D Series Syringe
Pump Safety Note when using a flammable fluid
The Teledyne Isco SFX system and syringe pumps must be placed within a prop-
erly operating vent hood (fume cupboard), when using ethane or any other flamma-
ble gas. Ensure that all SFE tubing connections are completely free of any gas
leaks by performing the leak test using CO
pump manual, Section 5 of the SFX 2-10 manual and Section 6 of the SFX 2-10,
220, and SFX 3560 manual). There must absolutely be NO gas leaks present before
introducing the flammable gas. In a temperature-stable, leak-free system, 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.
Important: When using a Teledyne Isco extractor (either SFX 2-10, SFX
220, SFX 3560) be absolutely sure the built-in venting fan (a brushless
motor) is operating properly.
The Teledyne Isco D Series Syringe Pumps and the SFX units, 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 cyl-
inder area and to reduce the amount entering the motor compartment.
•Seal the syringe pump motor compartment with tape and purge it with a con-
tinuous flow of nitrogen (N
mulating an explosive mixture around the motor and relays.
