Comprehensive selection of Collection / Storage plates & accessories ...

As specialists in microplates and microplate technology since 1987 - Porvair Sciences Ltd. has developed a comprehensive selection of high performance Collection / Storage plates and accessories.

Available in a choice of plate formats, surface treatments and volumes - Porvair's Collection / Storage plates are optimised to cover a wide range of sample preparation, sample storage and general assay applications. Latest additions to Porvair's Collection / Storage plate range include bacterial plates for growing cultures, sterile plates for sensitive microbiological and cellular samples and RNase / DNase free plates that provide the ideal, high integrity biological sample storage media.

Porvair can supply Collection / Storage plate plates to suit any need and budget. For general assay work the 1 ml round deep-well plate range, available in polystyrene and polypropylene, provides an affordable, easy to use solution. Where operational flexibility, solvent resistance and automation compatibility are important Porvair's range of precisely engineered polypropylene square deep-well plates provide leading edge performance. For maintenance of plate sample integrity in transport or storage scenarios Porvair's premium grade 96- and 384-well sealing mats provide a durable and tight seal against sample evaporation and possible contamination.

For applications requiring rapid large-scale generation of target compounds the 24-well deep-well microplate, with a capacity of 10ml volume per well, permits users to simply reproduce a large variety of chemistries in a single unit maximising both operational flexibility and target compound production.
