Round Bottom Microplate Maximises Sample Recovery

Deep well polypropylene microplates for life science sample storage

Deep well polypropylene microplates are commonly used for sample storage in life science laboratories. Polypropylene is an inert and heat resistant material, ideal for sample storage. However, not all grades of polypropylene are the same. For example, standard grades of polypropylene often have high concentrations of slip agents or plasticisers to aid the injection moulding process. This cost cutting exercise may aid rapid production of lower cost deep well plates, but risks compromising the integrity of your samples.

Porvair Sciences has added a new 1.2 ml Deep Well microplate, with round well bottoms for maximum sample recovery, to its family of 96-well square storage plates.

Storage temperature down to –80ºC

Manufactured from ultra-pure medical grade polypropylene, in a class 10,000 DNase/RNase-free cleanroom environment, the new plate offers high integrity storage of your samples at -80⁰C even over extended periods of time.

Each Porvair Sciences 96-well square storage plate offers a highly uniform working volume of 1 ml per well. The new plate design incorporates features that ensures easy and reliable stacking. Precisely manufactured to ANSI/SLAS dimensions ensures that these deep well storage plates completely automation compatible.

This new high-quality deep well plate has raised well rims to facilitate reliable heat seal closure, critical for long-term integrity of stored samples at -80°C. Used in conjunction with a support mat, Porvair’s new 1.2 ml square storage plates can be centrifuged at up to 6000 x g.
