Key-Head Color-Coded Medium Length PTFE Stoppers

Key-Head Color-Coded Medium Length PTFE Stoppers

Stoppers are used with laboratory glassware such as flasks and separatory funnels. PTFE has excellent chemical resistance and resists freezing in ground glass joints. Remove the colored polyethylene handle from the PTFE stopper before cleaning or exposing to temperatures above 80°C. Stoppers of sizes 9 through 22 are solid, and sizes 32 through 38 are hollow. Designed from ASTM Specification E675.

New Tariffs & Effects on Pricing

Tariff note: As we navigate the current environment of tariff surcharges and mid-year manufacturer price increases, we want to keep you informed. While we have avoided making specific decisions thus far, we anticipate that we will be forced to implement a cost adjustment policy to offset the fees we have already been absorbing. We are committed to transparency and moderation in this process.
