Porvair’s 96-well low-profile deep well plates are manufactured from RNase / DNase-free polypropylene. The company claims the microplates are available sterile or non-sterile and can be used in applications from -196 °C to +121 °C. The proprietary design of the autoclavable plates includes a V-bottom to enable liquid uptake, alphanumeric well coding for easy sample tracking, and raised well rims to enable integrity sealing.
