Product news

Porvair Sciences has introduced a new gas permeable Rayon microplate sealing film that has been shown to improve culturing of mammalian cells, bacteria and yeast culture by up to 70% compared to an impermeable seal.

Manufactured from high permeability, medical grade Rayon the new heat sealing film provides a uniform air and CO2 exchange with all microplate wells, unlike plate lids which favour exchange for wells near the plate edges. The innovative breathable membrane also reduces evaporation enhancing longer term incubation experiments.

Offering a high quality seal with all SBS / ANSI format microplates the new easy-piercing gas permeable Rayon sealing film allows direct sample recovery with single or multichannel pipettors and robotic probes. Designed for use with both manual and automated heat sealers the new sealing film uses a non-cytotoxic adhesive to minimise sample cross-contamination. Though available sterile the new gas permeable Rayon microplate sealing film cannot be autoclaved without reducing permeability.

To complement its range of affordable, high performance plate sealers, Porvair Sciences offers an extensive range of adhesive and thermal sealing films and foils. Porvair sealing films and foils offer a convenient and effective method for sealing 24-, 48-, 96-, 384- and 1536-well microplates. Sealing a microplate minimises evaporation and provides protection for samples during assay, storage, and shipment.

Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins.

The number of wells microplates contain can range from 6 to 3243 wells, with the 96-well format being the most commonly used. Microplates can come tailored for a range of applications including cell culture, PCR, filtration, storage, non-binding surface, protein crystallization, as well as pre-coated, deep well and normal Standard microplates. Additionally, options for microplate colors include clear , black, white or black with clear bottom and white with clear bottom for absorbance microplate reader applications.
