Abstract
A well plate seal includes a matt having a plurality of spaced apart wells for engaging and sealing a plurality of exit ports in a multi-well extraction plate. Unidirectional flow control valves are disposed in each of the plurality of matt wells for enabling liquid flow out of each of the exit ports only upon application of a pressure differential across each exit port.
Claims19
A well plate seal comprising:
- a matt having a plurality of spaced apart walls for engaging and sealing a plurality of exit ports in a multi well filtration/extraction plate;
- and
- a unidirectional flow control valve disposed in each of the plurality of matt wells for enabling liquid flow out of each exit port only upon application of a pressure differential across each exit port.
A sealing matt for a multi well filtration/extraction plate having a plurality of exit ports, said sealing matt comprising:
- a member having a plurality of spaced apart wells for engaging and sealing each of said plurality of exit ports;
- and
- a unidirectional flow control valve disposed in each of the plurality of member wells for enabling liquid flow out of each exit port only upon application of a pressure differential across each exit port.
A well plate seal comprising:
- a matt having a plurality of spaced apart wells for engaging and sealing a plurality of exit ports in a multi-well filtration/extraction plate, each well having a tapered sidewall for facilitating placement of said matt onto the filtration/extraction plate and sealing each of the exit ports;
- and
- a unidirectional flow control valve disposed in each of the plurality of matt wells for enabling liquid flow out of each exit port only upon application of a pressure differential across each exit port.
A method for providing flow control to exit ports of a multi-well filtration/extraction plate having a plurality of exit ports, said method comprising the steps of:
- installing onto said multi-well filtration/extraction plate a matt having a plurality of spaced apart wells, each well sealing a corresponding exit port and each well having a unidirectional flow valve for enabling liquid flow out of each exit port only upon application of a pressure differentiated across each exit port;
- and
- applying the pressure differential across each exit port.
