Wheaton® MicroLiter™ plate sampling system

A comprehensive range of microplates, glass inserts, sealing mats and/or caps with chromatography-based septa that offer security for even the most volatile samples.

Polypropylene μLplates™ have a variety of closures that will stabilise the sample during the analytical sample run and, if necessary, reseal after the sample has been injected. There is the option of choosing 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 are available for the appropriate application.

96-well round and square well microplates are available in a variety of volumes and options. Made of natural PP, they are made to ANSI specifications for 96-well microplates.

96-well round and square well covers are made of Ethylene Vinyl Acetate (EVA) and are pierceable by standard needle configurations found on most HPLC, LC/MS, CombiChem, and HTS instruments. They have a superior seal compared to similar products. For users who require some level of resealability, two silicone mats with a sprayed-on fluoropolymer resin barrier are available. Silicone mats are available in standard and pre-cut round or square well formats.
