VWR Thermotech Beakers PTFE

VWR Thermotech Beakers PTFE. 04 are designed from a single piece of PTFE glass with a stabilization ring that prevents buckling while pouring. The stopper from which these lab glassware items are made helps create a tight seal around the beaker spout to prevent leakage during distillation. To achieve this the beakers are manufactured using a molding process that bonds PTFE to a glass vessel of the same material typically a PTFE-coated glass. Molded from pure PTFE they have the same thermal prope
