Use Aijiren Tech™ Reacti-Vial™ Small Reaction Vials in the Reacti-Therm™ Heating and Stirring module. An internal cone makes small sample handling in these vials easy and convenient. The extra thick glass wall magnifies the sample, making these vials ideal for observing chemical reactions. Aijiren Tech Scientific is dedicated to

Jan 2, 2006 · Figure 3 - Typical mass chromatogram of volatile residue in hexane caused by PTFE/silicone septa: a) hexane extract of a piece of septum; b) vial septum was punctured once by a syringe to sample 1 μL hexane for GC analysis; c) hexane in the last vial was reanalyzed after 3 days; and d) analyzed immediately after 100 μL hexane was added from one vial to another (the septum was punctured 10

Jul 1, 2016 · Sample-vial septa must withstand multiple punctures during repeated syringe rinsing prior to injection, but there is no long-term requirement for a lasting seal. There are two remaining measures of vial septum performance: leakage and sample contamination. Vial septa can be made of softer and better sealing materials than inlet septa.

vial septum for multiple uses. This provides a direct route for microorganisms to enter the vial and contaminate the fluid.” Both the Pfizer-BioNTech and Moderna COVID-19 Vaccines are preservative free. The use of vial adapters and dispensing pins cause concern for a variety of reasons: • Syringes will be filled with exact dose (e.g., 0.3

Download the Specimen Collection & Transport Guide to provide a handy reference for you and your staff.

Aijiren polypropylene vials, or PP vials, are available in fill volumes starting at 250 µL. The complete range of 2 mL plastic sample vials have the same external dimensions as our standard wide-opening 2 mL glass vials and are fully compatible with our full range of screw caps, snap caps and crimp caps. 2 mL plastic vials (sometimes known as polypropylene HPLC vials or 1 mL plastic vials

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

When a chromatography system is underperforming from a physical issue with a sample vial, cap, or septum, autosampler misalignments, crashes or hangs that cause sequence problems can result. These problems can result in unnecessary downtime, expensive repairs, and even the loss of your precious samples.

A wide range of vials, closures, and accessory products designed for generalized and specific scientific applications. Various product formats, dimensions, and material compositions are available. Includes autosampler vials, cryogenic storage vials, and serum vials. Aijiren Tech Scientific is dedicated to improving the human condition through

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.

See the full range of sample containers from Alpha Labs for laboratory and clinical use including Universal containers, Bijou vials, transport tubes etc.

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 Aijiren Tech SureSTART Selection Guide to find the right septa and vial for your analysis.

Abstract. An important property of a vial cap is the ability to maintain the vial analyte concentration after multiple injections over time. This ability is influenced by different factors such as the volatility of the analyte/diluent, the number of injections, the elapsed time and the injector/cap septum used.

Septa. Septa are available in a variety of materials and thicknesses. PTFE Natural Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR. PTFE/High Performance Rubber is a highly pure synthetic red rubber septum
