Restek GC Equipment & Instruments
-
Mininert valves are very convenient for repetitive sampling and limit content exposure to the silicon septum. Models are available for screw-cap and crimp-top vials. The crimp-top valve for 20 mm ID glassware slides into the neck of the vial. Turn the threaded flange to secure a tight fit.
-
Securely holds up to 36 headspace vials (fits 6, 10, or 20 mL vials). Vials lock in rack for convenient one-handed cap removal. Openings in the bottom of each well facilitate drainage. Alphanumeric indexing on rack simplifies sample identification. Easy to clean and fully autoclavable.*…

Parker Nuts
RestekPlease note: Nuts and ferrules are not treated unless requested (custom parts). Nuts and ferrules normally are not in contact with sample pathway, and thus do not require coating.
-
Tapered for high recovery of contents Work with Mininert sampling valves
-
Ideal for dirty samples. Spiral bore prevents nonvolatile residue from contaminating the column. Visually observe the Press-Tight connection between the column end and liner Fit 0.32 and 0.53 mm ID capillary columns (column ODs from 0.5 mm to 0.8 mm) Slotted top prevents obstruction of…

Ridgid Tubing Cutter
RestekExcellent for cutting 1/8- or 1/4-inch metal tubing* Compact size is ideal for tight spaces Replaceable cutting wheel *Not for use with stainless steel tubing.
-
We designed the EZ No-Vent GC column-mass spectrometer connector to be simple and easy to use. A critical orifice in the EZ No-Vent connector minimizes the amount of oxygen allowed into the MS source, eliminating the need for purge gas as is required for other manufacturers' vent systems. This…
-
Flowmeters that can measure flammable gases are becoming mandatory due to the increased use of hydrogen in chromatography. With its Ex rating, the Restek ProFLOW 6000 meter is designed specifically with explosive and flammable gases in mind. The Restek ProFLOW 6000 is the only flowmeter you…
-
The inlet seal at the base of the Agilent 5890/6890/7890 GC injection port contacts the sample and must be changed frequently to prevent adsorption of active compounds. In addition, septum fragments and sample residue accumulate on the disk surface, requiring disk replacement. To reduce…
-
Valco fittings have been designed for the specific demands of instrumentation and manufactured with the tight tolerances and premium quality that analysts require. Connect four lines. 300 series stainless steel; stainless steel ferrules included. For 1/16" OD tubing.
-
Kit includes three O-rings, two plugs, one mounting screw, and one test block.
-
Reduces the release of hazardous materials from the capillary split vent into the lab Includes connecting lines and mounting kit
-
Proton exchange membrane (PEM) cell eliminates the need for liquid electrolytes. Maintenance-free palladium purifier removes oxygen to <0.01 ppm and moisture to <1.0 ppm. Produces continuous supply of 99.99999+% pure hydrogen gas. Does not require downstream gas filters. Maximum…
-
Choose preslit caps (available for some vials) to reduce the risk of needle bending, release vacuum from high-volume injections, and improve injection reproducibility when greater than 20% of vial volume is withdrawn.
-
Allow wrench-free column installations Available for standard (1/16") and compact (Agilent-style) ferrules Made from high-quality stainless steel
-
Inlet Liner Removal Tool
RestekEasily remove liner from injector—no more burned fingers Made from high-temperature silicone Won’t chip or crack the liner
-
Use to remove the septum nut and weldments during GC maintenance Use the smaller end to remove the septum nut Use the larger end to tighten the split/splitless weldment nut High-quality stainless steel construction Meets original equipment performance
-
Deactivated fused quartz helps eliminate activity for complete inertness along the GC flow path Universal fit: use with 0.1–0.53 mm ID Restek columns (0.33–0.74 mm OD) Optional Siltek deactivation is ideal for organochlorine pesticides analysis
-
Open-End Wrench Set
RestekHigh-quality 1/4" x 5/16", 3/8" x 7/16", 7/16" x 1/2", and 1/2" x 9/16" wrenches for tightening a wide variety of chromatography fittings.
-
Use for providing carrier, fuel, make-up, or auxiliary gases to laboratory instruments.
-
Can easily be packed with wool for dirty samples. Visually observe the Press-Tight connection between the column end and liner Fit 0.32 and 0.53 mm ID capillary columns (column ODs from 0.5 mm to 0.8 mm) Slotted top prevents obstruction of carrier gas flow Two designs available …
-
The electron multipliers manufactured by ETP use a proprietary dynode material. This material has a number of properties that make it very suitable for use in an electron multiplier. It has very high secondary electron emission, which allows exceptional gain to be achieved from each dynode. This…
