Screw cap vials are a practical packaging solution for sample-size health, beauty, and pharmaceutical products. Glass screw cap vials are impermeable and don’t undergo chemical leaching, so your products stay pure. Uses for Screw Cap Vials. Use glass screw cap vials to package sample products or as full-size product packaging options.
Aijiren screw thread top sample vials design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called a autosampler vial. And this sample vial is extremely compatible. The 1.5ml sample vial we usually say is the 2ml volume sample vial. The design of Aijiren screw thread top vials are developed from Europe and the United States, and the design feature is easy to use, especially the use of automated sample introduction system. Aijiren screw thread top vials also known as autosampler bottles.
Screw-top vials also come in different sizes, with vial caps made of either aluminum for crimp seals or plastic. Glass vials are available in 2 ml volume with a screw top. Inserts work in conjunction with any autosampler and fit either standard or wide openings vials.
Caps with solid PE liners offer good chemical resistance and low moisture vapor transmission rate and is great for nail polish remover and higher concentration acids & alkalis. Good for non-oil products filled at room temperature. Because this lining system is paperless, your samples will not be contaminated with fiber or paper particles from the closure. Available in Phenolic caps.
These caps form an exceptionally tight seal and offer a good chemical barrier. This liner molds itself around the sealing areas of the finish as the cap is screwed on, virtually eliminating leakage, evaporation, contamination, binding and backing off. Great for everything from liquids, to soaps, to macro-invertebrates.
The non-pre-slit septas help to reduce carryover from vial to 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.
Teflon and silicone rubber or ultra-pure silicone are used as raw materials to ensure that the septa are non-toxic; to ensure excellent functions, it is particularly suitable for gas chromatography, and to ensure that the septum does not fall into the sample vial during the injection process
The Screw Caps that are inlcuded with this kit are knurled on the sides for excellent gripping and comfort when applyting to the vial. The silicone rubber / PTFE septa used were designed to provide the right amount of resistance to autosampler needles during the injection process so that they penetrate the vial properly without damaging the septa or the injection needle. Too much or too little resistance to the needles can damage the septa, compromise resealing, cause needle blockage from coring of the septa material and even damage your autosampler. These septa perform even when using a wide range of needles: fine, blunt or even dull. Low sample or solvent evaporation performance even after multiple injections have been observed when using aijiren caps.
Screw Cap Vials are universal. Screwing the cap applies a mechanical force that squeezes the septum between the glass rim and the cap. Screw caps form an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.
Although most laboratories have switched to 9 mm screw thread vials for a wider opening while still being autosampler compatible, some labs use 8-425 vials for storing solvents. The standard opening 8-425 vials have more threads per inch, so there is less likelihood that volatile solvents will evaporate over time.
These vials are the preferred choice for modern autosamplers. With a focus on improved sample security and integrity, we now offer innovative 9mm closures and 9mm screw top vials for consistent productivity on every separation.
Standard opening screw-thread vials are manufactured from borosilicate glass and have a maximum fill volume of 2 ml.
