PTFE Stopcock For Precise Flow Control

This straight-bore, bi-directional PTFE/Glass stopcock is a must-have in the lab, designed for precise fluid control in harsh environments. The stopcock features a durable PTFE (Teflon) valve core and glass body for chemical resistance, thermal stability, and leak-free performance. It is ideal for medical, chemical, and biological laboratories, ensuring precision in reagent handling, distillation, and vacuum applications.

Specification Of Stopcocks

Features Of Stopcock Medical

● Material Advantages: PTFE valve core resists aggressive chemicals (acids, solvents); glass body ensures clarity and inertness.

● Precision Engineering: Straight-bore design minimizes dead volume for precise flow control.

● Standardized Dimensions: Compatible with most lab equipment (see table below).

● Reusable and Autoclavable: Saves costs and ensures sterility in medical applications.

Applications Of PTFE Stopcock

● Chemical Labs: Control of corrosive reagents in titrations or synthesis.

● Biotech/Pharmaceuticals: Sterile liquid delivery in cell culture or chromatography.

● Medical Use: IV lines or vacuum systems requiring a leak-proof seal.

Instructions Of PTFE

● Gently lubricate the PTFE tubing (silicone grease can be used for high vacuum).

● Install the side arm onto the tubing/equipment; align the bore.

● Smoothly rotate the handle to adjust the flow.

FAQ

1.How do I clean a PTFE stopcock after exposure to chemicals?

Rinse with a compatible solvent (e.g. acetone for organics) and autoclave as needed.

2.Can this stopcock withstand high pressure applications?

Yes, but please check the ID size - the smaller the ID (2-6 mm), the more pressure it can withstand.

3.What is the difference between a PTFE plug valve and a glass plug valve?

PTFE plugs are chemically resistant; all-glass plug valves are fragile but extremely inert.
