These one-piece microvials have a very low residual volume due to a specially shaped deep and narrow inner reservoir which collects the liquid in the base so compatible autosamplers can collect all but 1-2 microliters of sample while having a total sample volume of 1.2mL. The outer dimension for these vials is 12x32mm. What are High Recovery vials?
Ensure optimal performance of your GC instrument with bleed and temperature optimized Aijiren Tech™ BTO and TR-Green Septa. Made of low-bleed silicone, these septa have excellent mechanical properties, are ideal for demanding GC-MS applications, and may be used reliably up to 400 °C.

Most vial cap septa are lined with a protective layer of polytetrafluoroethylene (PTFE) to prevent solvent attack. As shown in Figure 3, PTFE effectively prevents septum breakdown due to solvent exposure. In comparison, unlined vial cap septa exhibit bleed after just 24 hours at room temperature.
Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs. 20mL; Flat Bottom; Beveled Edge Crimp Top. Contains Vials only. Caps needed: 03-375-22E. 20mL; Flat Bottom; Beveled Edge Crimp Top.

Jul 10, 2012 · Because with an increase in carrier (helium) flow (from 0.6 to 1 mL/min), a corresponding shift of each peak's t R to a lower magnitude was observed, for sake of consistency, further measurements were made at a fixed carrier flow of 0.8 mL/min. We analyzed 3–5 septa in each category/batch and more than five runs (even more than 10) for each
BTO septa are bleed and temperature optimized with a maximum temperature of 400 °C, for the most demanding GC and GC-MS applications. They attain remarkable softness and puncturability at high temperatures. However, at lower temperatures, BTO septa have limited puncturability and septum coring or needle damage may occur.
These septa are formulated to extend low-bleed and outstanding mechanical properties of premium GC septa to the highest-temperature applications. It retains remarkable softness and piercability at high temperatures, with extremely low bleed. Septa are 3mm thick, except Shimadzu-style plug septa, and are packaged in glass vials.

• For GC/MS and other highly sensitive detectors • Packaged in Ultra Clean White Non-Plastic Trays • Kit contains Vials & 11mm Aluminum Crimp Caps w/ Ultra GC/MS PTFE Septa • Chemically resistant polypropylene vials are an economical alternative for microsampling instead of using limited volume inserts.
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
20 mm PTFE/Butyl Septa/Cap/Springs PerkinElmer Choose the right septa for your analysis. Although a wide variety of septa is available, chemical compatibility and temperature are the most critical to the analysis. Temperature applies not only to the vial, but also to the temperature of the instrument’s needle used for pressurization and sample
