Porvair Sciences has developed Biovyon C18 silica microplates, which it claims provide higher consistency and greater recoveries for assays of small sample volume used in solid phase extraction (SPE).
These 96-well microplates are designed to provide greater efficiency than traditional packed-bed SPE microplates, which Porvair claims perform inefficiently in the shallow sorbent beds needed to get good recovery from smaller sample volumes.
They do this by immobilising the C18 sorbent within the microplates' porous Biovyon polymer - a pharmaceutical-grade polyethylene material that, in preventing the C18 sorbent from forming liquid channels, minimises sample hold-up volume.
Biovyon C18 is offered in 96-well microplates as a 10mg per well loading suitable for low-volume bioassay preparation and clean-ups.
