Aijiren vials and caps provide simple ways to boost laboratory productivity and return on investment. Aijiren premium certified vials, closures, high recovery vials, and vial inserts offer industry-leading performance; from the lowest bleed septum materials in our caps to the most inert glass vial materials, we are continuously refining our offerings by addressing small details delivering

a vial septum and then installing the vial in the sample tray. I adjust the needle to the target depth, then lift the vial by its cap. In the case of my instrument, I expect approximately 1 mm of vertical play if the system is adjusted properly. This play allows a safety margin in case of any variation in vial depth for a given vial model. This

Thermo Scientific™ Septa Caps include a bonded-in 0.045 in. thick septa. The same high quality septa caps used on our Thermo Scientific VOA Vials, septa bottles and septa jars. Processed to meet EPA performance–based specifications for Volatile Organic Analysis. White polypropylene open top cap with bonded PTFE-lined silicone septum.

The septum you choose for your autosampler vial can impact sample evaporation, sample security, needle bending and blockages, and instrument down time. Don’t let the complexities of septa selection slow you down. Use the simple online Thermo Scientific SureSTART Selection Guide to find the right septa and vial for your analysis.

Catalog number: TS-13019. For a convenient, versatile, and cost-effective vial and closure system, choose Thermo Scientific™ Screw Cap Septum Vials. Made of autoclavable borosilicate glass and available with a wide assortment of special closures and accessories, these vials are ideal for sample collection and small derivatization reactions

Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs. Type 1 borosilicate glass. Clear glass vials with 20mm crimp seal finish are designed to fit most headspace autosamplers. Flat bottom vials maximize heating efficiency when used with bottom.

Apparently the silicone septum doesn't withstand organic solvents very well, so better prepare a new blank for each sequence. The attached image shows the old blank (black) compared to a fresh one

May 23, 2001 · Recent advances in continuous-flow isotope ratio mass spectrometry have made possible automated analysis of δ 13 C and δ 18 O in CO 2 in air from 10-mL septum-capped vials. With the potential to collect, transport, and analyze a large number of air samples using these small inexpensive vials, the opportunity exists for routine and

May 29, 2021 · The glass vial is tightly closed with a screw cap with Teflon septum. 4. The glass vial is transferred to an oven or water bath set to 80 °C and incubated for 30 min. 5. The glass vial is removed from the oven or water bath and allowed to cool to room temperature and the solvent evaporated under a stream of N 2 gas. 6.

The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial.

The septum forms a barrier between your sample analyte in the vial and the outside atmosphere. This barrier protects your sample from external contamination while allowing a needle (from a manual or automatic syringe) to enter the vial, and extract the sample for the next stage of separation.

selection guide Overview Diferent septa material for LC and GC applications There are many diferent types of materials used to produce the septa found in LC and GC vial caps. This document will provide you with the technical guidance you need in order to make the right selection. Choosing the right septa

Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs. Type 1 borosilicate glass. Clear glass vials with 20mm crimp seal finish are designed to fit most headspace autosamplers. Flat bottom vials maximize heating efficiency when used with bottom.

vial because the resealing characteristics of the septum act as a squeegee to wipe solution from the outside of the needle. Typically, a non-slit septum exhibits resealing capabilities for a limited number of needle punctures but for long-term storage in the vial, using a new non-punctured septum is best practice.
