Chromatography Fittings
Dynalon™ Two Way Tubing Stopcocks
For industrial use. Dynalon™ Two Way Tubing Stopcocks allow the transfer of liquids or gases through tubing by releasing the flow or blocking the flow.
MilliporeSigma™ Supelco™ Supeltex™ M-2B Double-Tapered Ferrule, 0.32 mm I.D. to 0.53 mm I.D. Column
Max. Temp.: 350°C. Composition: DuPont VESPEL SP-211 (75% polyimide, 15% graphite, 10% PTFE). Characteristics: Conforms easily to capillary column, ensuring an effective seal and less chance of breakage.
MilliporeSigma™ Supelco™ Swagelok™ Union Cross, 400-4, Brass, 1/4 in.
Union cross generally divides the eluent flow into three directions which is coming from the pump. In gas system, pure gases from mass flow controllers are converged at the union cross and in turn flow into different size tubing to generate turbulence which produce homogenized gas.
Cytiva™ Union 1/16 in. Female to 1/16 in. Female Chromatography Fitting
Works with connectors with an outer diameter of 1/16 in. For ÄKTA™ systems.
MilliporeSigma™ Supelco™ Swagelok™ Reducer, 400-R-2, Brass, 1/4 in., for tube 1/8 in.
Nuts and ferrules included.
MilliporeSigma™ Supelco™ Swagelok™ Fine Metering Valve Brass, angle arms 1/8 in.
Use for very accurate flow regulation. Install a flow measuring device downstream. Nuts and ferrules included. An optional vernier handle (Cat. No. 22122, order separately) is available for added convenience.
MilliporeSigma™ Supelco™ Supeltex™ M-1 Packed Column Ferrule, 1/8 in.
Characteristics: Ideal for connection to mass spectrometers. High reusability. Isothermal use only. Material Composition: Ceramic-filled PTFE. Maximum Temperature: 250°C
Synthware™ Chromatography Flow Control Adapters
High vacuum valve with metering tip to adjust air pressure
Restek™ Male Pipe to Valco™ Internal Adapter Connector
Makes a minimum volume connection from a female pipe fitting on a pressure gauge or regulator to a Valco zero-dead-volume fitting.
Restek™ Flexible Stainless Steel (SS) Hose
Flexible stainless-steel hose with 1/4 in. female NPT.
Restek™ Graphite O-Rings
For Splitless Liners for Shimadzu 2010, 2014, and 2030 GCs
Restek™ PEEK Secure-Fit Fitting, Single Connector
Secure-Fit connectors ensure a consistent, leak-free seal and eliminate excess dead volume.
Restek™ Replacement Inlet Cross-Disk Seals for Agilent 6890 GCs
Ideal for high-flow split applications >500mL/min. on Agilent 5890 GCs.
Restek™ Replacement Deactivated Transfer Line
For EZ No-Vent GC Column-Mass Spectrometer Connectors.
