Bio-Rad BioLogic LP System - Manual (Page 29)

4.0 SYSTEM PLUMBING
This chapter begins with discussion of plumbing practices and general guidelines, followed by a general pro-
cedure for plumbing the major system components. Later sections discuss how to plumb Bio-Rad’s low
pressure valves.
4.1 GENERAL GUIDELINES FOR PLUMBING THE SYSTEM
The BioLogic LP uses the following tubing:
• System tubing: 0.8mm ID or 1.6mm ID Tygon tubing.
• Pump Tubing: 0.8mm ID, 1.6mm ID, or 3.2mm ID PharMed tubing. Refer to the following table
when selecting a tubing.
Warning
Do not use pump tubing with wall thickness greater than 1.0 mm. Using tubing with a wall thickness
greater than 1.0 mm can damage the pump and void the warranty.
