No risk for exctractables, no risk of losing valued sample by taking the wrong vial and closures, which might not be compatible with the sample or solvent. Each lot of certified kits is tested by HPLC/UV and GC/MS against 15 critical parameters. Certificate of Conformance included in every pack.
Purge pump at high flow rate (e.g., 5-10 mL/min.), prime system if necessary. (Prime each pump head separately.) If system has check valve, loosen valve to allow air to escape. If problem persists, flush system with 100% methanol or isopropanol. If problem still persists, contact system manufacturer.
unassembled HPLC glass vials testing Autosampler Vials, Caps and Closures | Fisher Scientific Minimize contamination from handling with pre-assembled caps and septa; compatible with most HPLC and GC autosamplers.
Standard chromatography vial sizes include 8 x 40mm, 12 x 32mm, and 15 x 45mm. Robotic Arm Machines (R.A.M.) use a non-standard 9mm vial with a magnetic cap. For autosamplers, choose a vial designed for that specific brand. Inserts can be used to decrease the capacity of the vial while maintaining the exterior dimensions.
We provide a complete range of high-quality products for accurate, brilliant results in a variety of analytical applications, including HPLC, GC, Karl Fischer titration, elemental trace analysis, classical analysis, air monitoring, food and beverage analysis, and proficiency testing.
