2ml 9-425 Autosampler Vial Cap with PTFE/Silicone Septa

The 2ml 9-425 autosampler vial with 11.6mm x 32mm size, and 9-425 9mm screw top, We performs rigorous testing of dimensions such as polishing, OD and length – to ensure that each vial is exactly matched to the autosampler jaws and injection system (DIN/ISO Standard), all dimensions are strictly subject to trouble-free operation, the vials can ensure running smoothly in the autosampler. 

Polypropylene screw cap with pre-slit septa provide an evaporation-proof seal. Bi-layer includes silicone and PTFE. Silicone septa for multiple injections. PTFE-lined screw cap for organic samples.Writing patch for sample identification or labeling. Short-thread caps and vials require fewer turns to make a tight seal, saving time, especially considering how often vials need to be opened and closed, and how many samples you have.

Pre-opened seam Nature PTFE with no open seam white silicone partition can reduce the HPLC needle damage rate, to ensure good puncture capacity, thickness of 1mm± 0.05, Shaw hardness of 45 degrees, closely fit the cap.Cap/Septum has a natural Pre-slit Blue polytetrafluoroethylene (PTFE) and white silicone septa are convenient and minimize contamination from handling.Cap/Septum  tested by head space GC to ensure proper curing of silicone polymer.2ml HPLC Vials caps and septa with most close space tolerance and caps and septa meet standards set by governing bodies.

The 2ml 9-425 autosampler vial can be used on all common autosamplers, preferentially they are found on Agilent, HTA, Shimadzu, Thermo, Varian, Waters, etc.Aijiren 9mm vials and screw caps are the perfect fit for HPLC and Gas Chromatography instrument platforms and used in applications including pharmaceutical, environmental, forensic science, bio-pharmaceutical.
