Autosampler Vials for GC and HPLC with Screw Caps PTFE Silica Septa

Autosampler Vials for GC and HPLC are typically grouped according to the diameter of the vial, the height of the vial, and the thread finish. Both clear glass and amber glass are highly inert. Amber glass protects sensitive natural samples by avoiding exposure to UV rays. Vials are mainly used to inject samples from autosamplers. 2 mL vials are more commonly used, but are sold in multiple sizes. The autosampler needle penetrates the cap during injection and extracts the required sample fraction from the vial. Aijiren is proud to offer numerous vials for chromatography applications.

Screw Autosampler Vials for GC and HPLC is the most used in 2ml Autosampler vials.It is suitable for Agilent, AB Sciex, Brook, Techcomp, PerkinElmer, ThermoScientifics, Shimadzu, Waters, CTC autosampler and other rotary or robotic arm samplers.40% larger than standard narrow opening vial, prevents syringe problems. The special thread design ensures a consistent seal. Graduated write-on marking spot area, measures 0.5, 1.0 and 1.5ml.The ever flat-bottomed guarantee consistent matching between vials and truly neck 8mm for Standard Glass insert.

Caps are made of high quality polyproylene to exact manufacturing tolerances and lined in a controlled manufacturing environment.Polypropylene Screw Cap with Septa - Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

PTFE and silicone rubber or ultrapure silicon are used as raw materials so that the diaphragm is non-toxic. To ensure excellent function, is particularly suitable for gas chromatography, and ensures that the diaphragm during the injection process does not fall into the sample vial.The adhesive-free bonding process is used to combine the polytetrafluoroethylene membrane and the silicon rubber or silicone bond together to maintain the excellent characteristics of the two materials. The polytetra fluoro ethylene layer of the compound diaphragm is in contact with the reagent. It is chemically inert, resistant to acid, alkali, temperature, and adhesion. It does not work with concentrated acid, concentrated alkali or strong oxidant even at high temperature. At the same time, the elasticity of silicone rubber or silicone layer can ensure sealing performance.
