GC Connectors, Valves & Tubing Products & Reviews

UHP stainless steel regulators are the standard for ultra-high-purity and corrosion-resistant pressure regulation. They are more easily purged of atmospheric components compared to brass gas regulators, making them ideal for the most demanding applications. Stainless steel is especially useful in atmospheres of dry corrosive gases such as hydrogen. All regulators are rated to 3,000 psig (20,684 kPa) maximum inlet pressure.…

for Agilent GCs with 5971/5972, 5973, 5975, or 5977 GC-MS  

Dependable leak-free capillary connections allow reliable backflush, split flow, heart-cutting, and GC x GC on Agilent 8890 and 7890 GC systems. These devices are low thermal mass, oven mountable, and inert.

Valco GC valves have been in almost all commercially-produced gas chromatographs from the time that valves originally began to replace other injection methods. New designs are smaller and easier to service, but still exhibit the quality and value that made them the industry standard. Medium temperature GC valves have a rotor made of Valco E, a polyaryletherketone/PTFE composite. High temperature GC valves use a polyimide/PT…

Attach to the column in seconds to form an airtight seal. Increase column lifetime—prevent moisture and air from entering the column during storage. Two styles to choose from: glass or silicone material. Glass caps are color-coded for identifying detector and injector ends. Not recommended for reuse.

Frustrated with leaky, hard to use press-fit connectors? Now anyone in your lab can easily connect guard columns or retention gaps to GC columns by using Agilent Ultimate Union kits. 

Employing the easy release clamping design, these fittings offer a quick and simple solution to vacuum system design and assembly. Bakeable to 150º C when using Viton O-Rings, these fittings are ideal for roughing or high vacuum applications.

HTS and HTC PAL Valve Supplies   To better serve Agilent instrument users who choose CTC Analytics autosamplers for high-throughput and flexible sample introduction, Agilent has partnered with CTC to provide a fully integrated system, including CTC-approved valve supplies.Whether your HTS or HTC PAL autosampler uses the Agilent proprietary Rheodyne high-pressure 600-bar injection valve or Valco Cheminert injection valves, Agil…

Agilent's QuickSwap Capillary Flow Technology module and pre-swaged fused silica tubing restrictors can increase the productivity of your Agilent 5973N and 5975 inert MSD systems, allowing you to change columns without venting the MSD. QuickSwap not included.

Agilent high-quality copper, stainless steel, and UltiMetal Plus tubing are manufactured and cleaned for chromatographic use. Agilent Tubing comes in different lengths and depending on your flow requirements, are available in 1/16 inch, 1/8 inch, or 1/4 inch. UltiMetal Plus tubing comes in 1/16 inch for inert environments.

Growth factor-rich supplement for the expansion of cells in vitro

The Dual Layer PEEK tubing eliminates any concern that a critical sample stream could be contaminated by pigments used to color code the tubing.  The pigmented layer surrounds a separate but integrally-bonded inner layer of natural PEEK. The 1/16" OD tubing is available in standard sizes, or in OEM quantities with any ID you specify, from .002" to .030". The ID tolerance of ±.001" is equivalent to or better than that of tubing…
