Abstract
A multi-well filtration apparatus is provided that has a housing, a multi-well filtration plate, and a pivotable member. The pivotable member secures the multi-well filtration plate to the housing and is associated with a resilient member. When the multi-well filtration plate is pressed against the pivotable member, it pivots, and the resilient member compresses to allow the pivotable member to instantaneously engage the multi-well filtration plate to secure it to the housing. The pivotable member can quickly release the multi-well filtration plate by simply exerting a force on a surface of the pivotable member.
Claims20
A multi-well filtration apparatus, which comprises:
- (a) a housing;
- (b) a multi-well filtration plate having a plurality of wells that each have located therein;
- and
- (c) attached to the housing a means for securing the multi-well filtratic to the housing, the securing means including at least one pivotable member and permitti multi-well filtration plate to be secured to the housing by pressing the multi-well filtration against the at least one pivotable member of the securing means.
A multi-well filtration apparatus, which comprises:
- (a) a housing having a vacuum chamber;
- (b) a means for retaining at least one filter;
- and attached to the housing
- (c) a means for securing the filter retaining means to the housing, the filter retaining means being secured to the housing such that the vacuum chamber can draw liquid therethrough, the securing means having a movable member and a resilient means, which movable member and resilient means allow the securing means to open in response to a force from the filter retaining means to receive the filter retaining means, and to close to instantaneously secure the filter retaining means to the housing.
A filtration apparatus, which comprises:
- (a) a housing;
- (b) a member that contains at least one filter;
- and
- (c) at least one pivotable member having a guiding surface and being capable of pivoting in first and second opposing directions, the at least one pivotable member being attached to the housing and pivoting in a first direction in response to a force applied to the guiding surface by the member that contains at least one filter and pivoting in a second direction to instantaneously secure the member that has at least one filter to the filtration apparatus when the force is no longer applied to the guiding surface.
