Abstract
This disclosure provides, among other things, a filtration device comprising an open bottomed multi-well plate, a planar spacer that comprises apertures, and a porous capillary membrane. In the device, the planar spacer is sandwiched between the multi-well plate and the porous capillary membrane and the planar spacer is bonded to both the multi-well plate and the porous capillary membrane via an adhesive. Kits and methods of making the device are also provide.
Claims20
A filtration device comprising:
- (a) an open-bottomed multi-well plate;
- (b) a planar spacer that comprises apertures, wherein the positioning and size of the apertures match the positioning and size of the wells of the multi-well plate;
- and
- (c) a porous capillary membrane;
- wherein:
- (i) the planar spacer is sandwiched between the multi-well plate and the porous capillary membrane,
- (ii) the apertures of the planar spacer are aligned with the wells of the multi-well plate,
- (iii) the planar spacer is bonded to the multi-well plate via an adhesive;
- and
- (iv) the planar spacer is bonded to the porous capillary membrane via an adhesive.
