A comprehensive line of 96-well microplates for chromatography, the Plate Sampling System uses closures familiar to those who work with standard chromatography vials. Polypropylene µL-plates have a variety of closures that will stabilize the sample during the analytical sample run and, if necessary, reseal after the sample has been injected. You may also choose the security of a stopper coupled with the strength of a mechanical closure system. The mechanical closure system permits even GC samples can be converted to 96-well format, by sealing the limited volume insert on the inside surface of the insert and compressing the PTFE/silicone rubber using a mechanical seal. A variety of insert options let you choose the specifications appropriate for your application.
