Evacuating apparatus for a microtitration diaphragm plate
First Claim
1. An evacuating apparatus for applying suction to the underside of a microtitration diaphragm plate including a plurality of diaphragm receptacles each having an open top and a diaphragm bottom, the evacuating apparatus including a housing (1) defining an evacuation chamber (2) having an aperture (4) provided in a top wall of said chamber (2) and having associated therewith peripheral gasket means (5) for supporting a rim of said microtitration diaphragm plate (6), and further comprising a carrier (18) including support means (8'"'"') for supporting a microtitration recipient plate (19) including a plurality of closed bottom receptacles (20) each having an open top and a closed bottom, said carrier (18) being adapted to be displaced between an access position wherein said recipient plate (19) may be positioned onto or removed from said support means (8'"'"'), and a loading position wherein said recipient plate (19) is disposed within said chamber (2) below said diaphragm plate (6) so that said diaphragm receptacles (7) of said diaphragm plate (6) vertically register with said closed bottom receptacles (20) of said recipient plate (19), said carrier (18) having a face plate (15) which sealingly engages a peripheral edge of an access opening (30) of said chamber (2) when said carrier (18) is in its loading position.
