Screw Top 9mm Black Plastic Closed Top Vial Cap, 100/Pk - CV1809
Manufactured from chemically resistant polypropylene, Tisch screw-thread caps provide a dependable seal without introducing extractable contaminants into analytical samples. Precision thread pitch and tolerances support consistent hand-tight sealing and reliable engagement with automated capping and decapping station mechanisms. Consistent production quality eliminates the containment variables that compromise injection precision, supporting validated analytical performance at every step.
From tray loading through the final injection in an overnight sequence, your sample containment system should perform without introducing the variables your method is designed to control. Chemical resistance and color-coded identification options let you organize your sample trays efficiently without introducing extractable contaminants into the sealed environment. Eliminate sample containment as a source of analytical uncertainty by choosing chromatography consumables manufactured to the tolerances your instruments require.
