Our precleaned, Type 1 borosilicate clear or amber glass vials are washed in non-phosphate detergent, rinsed three times with tap water, and rinsed with ASTM Type-1 organic-free water to remove detergent. Post cleaning, vials are assembled with PTFE/silicone septa and open-top polypropylene caps. VOA (EPA) Vials

GC Septa. The GC septum should be routinely replaced to reduce the risk of leaks and septum particle contamination. In fact, if the instrument is in heavy use, change the septum daily. Repeated use of the same septum will result in increased coring, which may introduce a leak and/or result in septum fragments being deposited in the inlet liner.

Screw-thread sample vials are manufactured from either clear 33 expansion borosilicate clear glass (Type 1, Class A) or 51A amber glass. Vials maintain PH level and eliminate ion leaching. Choose from a polypropylene cap with a PTFE-lined foam backing or a polypropylene cap with a PTFE-lined silicone septa.

Borosilicate glass (low impurity Type I Class A) with one twist cap and pre-inserted, pre-slit PTFE/silicone septum for ease of sample preparation and autosampler needle penetration. Vial size is 12x32 mm, with a writing patch on the side. 100 vials per pack. Use for the following autosamplers and racks: SIL-20A/AC, SIL-30AC, SIL-40, LC-40

Jul 10, 2012 · Introduction. In past gas chromatographic (GC) analyses, it has been reported that septa of various makes release volatile organic compounds (VOCs) when subjected to high temperatures ().These reports also revealed the frequent presence of contaminants such as finger oils from handling, or organic contaminants picked up during storage of these septa.

A GC septum is located at the top of the injection port and serves two functions: 1) providing a leak-free seal to maintain carrier gas pressure inside the system. 2) handling repeated puncturing by a syringe needle for sample introduction purposes without severe coring or leaking. Temperature-Programming: When performing temperature-programmed

Inlet septa are used to maintain a leak-free seal under the septum nut in the GC inlet, even after many repeated injections. The dimple in the middle of the septum guides the syringe needle through the inlet into the inlet liner to minimize damage to the needle and to ensure injection consistency. Bleed temperature optimized (BTO) septa are

Advanced Green inlet septa eliminate sticking and reduce coring. Bleed temperature optimized (BTO) inlet septa are preconditioned and ready to use with low-bleed, mass spec capillary columns. Our long-life septa are specially formed for extended use, meaning less downtime.
