KONTES* Three-Valve Cap System


Provides on-off control for all three ports of the reservoir cap. Helium-tight valves maintain the mobile phase in a sealed environment between runs. Cap body is manufactured from PTFE, while the color-coded valves are made of CTFE with TFE/propylene O-rings (standard version) or stainless steel with Kalrez* O-rings (THF-resistant version). 1/4-28 flangeless fittings and adapters are supplied to allow simple, easy connection to any HPLC pump system. Supplied with a three-valve cap, conical bottom reservoir, fittings kit and PTFE tubing. The standard three-valve cap system is recommended for most solvents used for HPLC mobile phase. Not for tetrahydrofuran (THF), chlorinated hydrocarbons, ethers or ketones. The THF-resistant three-valve cap system is recommended when using tetrahydrofuran (THF), chlorinated hydrocarbons, ethers or ketones.
