Porvair Sciences has launched a range of 384-well filtration plates with a drip geometry designed to provide unmatched sample recovery.
By re-shaping the drip director and giving it a compound curve structure, the filtration plates virtually eliminate the traditional 'hanging filtrate' effect in which excess filtrate clings by surface tension to the outside of the structure.
As well as improving total sample recovery, the plate design helps to minimise work surface and sample contamination as well as improving productivity when used with automated liquid handlers.
Available with four different membranes with a 140uL volume, Porvair 384 well filter microplates are made from high-grade polypropylene to minimise extractables. They are available with glass fibre membrane of three different pore sizes (0.7um, 1.2um and 5.0um) to provide optimum filtration for a wide range of high biomolecule binding applications. Porvair also offers a 384-well filtration plate with an ultra-high molecular weight polyethylene membrane of 25um pore size, suitable for low biomolecular binding studies - such as sequencing reaction clean up - to complete its new line-up.
