Wilmad-LabGlass, 727-LPV-250M, 4 mm Medium Wall Low Pressure/Vac Suprasil EPR Sample Tube 250 mm L

Features:

• A greaseless PTFE piston provides a 100% contamination-free seal.
• The axial symmetric design guarantees its application in spinning experiments.
• More economical to reduce experimental costs

A 4X larger sealing surface eliminates leaks and greatly increases its lifetime when compared to traditional gas-tight tubes. It continues to offer a convenient flame-free sealing solution for air sensitive or volatile liquid samples at any pressure from vacuum to pressure slightly above 1 bar.
