Bioreactor chamber
A bioreactor system includes a sample chamber capable of receiving a specimen and a cover which can be placed on the chamber to enclose the specimen within the chamber. A first member is movable between (i) a closed position in which the member restricts the cover from being moved away from the chamber in a first direction, and (ii) an open position in which the member does not restrict the cover from being moved away from the chamber. When the first member is in the closed position there is a substantially liquid proof seal between the cover and the chamber.
1. A bioreactor system, comprising:
a sample chamber capable of receiving a specimen;
a cover which can be placed on the chamber to enclose the specimen within the chamber, the cover including a first side and a second side substantially opposite to the first side;
a first member which is movable between (i) a closed position in which the member restricts the cover from being moved away from the chamber in the first direction, and (ii) an open position in which the member does not restrict the cover from being moved away from the chamber, whereby when the first member is in the closed position there is a substantially liquid proof seal between the cover and the chamber, the first member configured to engage a portion of the cover along the first side of the cover when the first member is in the closed position; and
a lip extending from a portion of the sample chamber and configured to engage a portion of the cover along the second side of the cover and restrict the cover from being moved away from the chamber in a first direction.
2. The bioreactor system of claim 1 , wherein the member is secured to the chamber.
3. The bioreactor system of claim 1 , wherein the member is rotatable about an axis, and wherein the first side of the cover overhangs the chamber, whereby the internal pressure in the chamber forces the member towards the closed position.
4. The bioreactor system of claim 1 , wherein the chamber includes at least one protrusion at both ends of the chamber which positions the cover in a second direction.
5. The bioreactor system of claim 1 , wherein the cover includes a groove in which a portion of the first member resides when the first member is in the closed position.
6. The bioreactor system of claim 1 , wherein the member can be removed from the chamber when the member is in the open position.
7. The bioreactor system of claim 1 , wherein the member is rotatable about an axis which is substantially perpendicular with the longest dimension of the chamber.
8. The bioreactor system of claim 1 , wherein the member is an elongated member.
9. The bioreactor system of claim 1 , wherein the member is rotatable about an axis which is substantially parallel with a longest dimension of the chamber.
10. A bioreactor system, comprising:
a sample chamber capable of receiving a specimen; and
a cover which can be placed on the chamber to enclose the specimen within the chamber, the chamber including a lip which engages a portion of the cover along a first side of the cover to resist the cover in moving in at least a first direction.
11. The bioreactor system of claim 10 , further including a compressible sealing member which can be compressed between the cover and the chamber to provide a substantially leak proof seal.
12. The bioreactor system of claim 10 , further including a member which is movable between (i) a closed position in which the member restricts the cover from being moved away from the chamber, and (ii) an open position in which the member does not restrict the cover from being moved away from the chamber.
13. The bioreactor system of claim 12 , wherein the member is secured to the chamber.
14. The bioreactor system of claim 10 , wherein the chamber includes at least one protrusion at both ends of the chamber which positions the cover in a second direction.
15. The bioreactor system of claim 10 , wherein the lip includes a transition zone surface which guides the cover when the cover is first inserted into the chamber and a retaining surface which assists in securing the cover to the chamber once the cover is fully inserted into the chamber.
16. A bioreactor system, comprising:
a sample chamber capable of receiving a specimen;
a cover which can be placed on the chamber to enclose the specimen within the chamber, the chamber including at least one protrusion at both ends of the chamber which positions the cover in a first direction; and
a lip extending from a portion of the sample chamber and configured to engage at least a portion of the cover along a side of the cover to resist the cover in moving in at least one direction.
17. The bioreactor system of claim 16 , further including a compressible sealing member which can be compressed between the cover and the chamber to provide a substantially leak proof seal.
18. The bioreactor system of claim 16 , further including a member which is movable between (i) a closed position in which the member restricts the cover from being moved away from the chamber, and (ii) an open position in which the member does not restrict the cover from being moved away from the chamber.
19. The bioreactor system of claim 18 , wherein the member is secured to the chamber.
20. The bioreactor system of claim 18 , wherein the member engages at least a substantial portion of the cover along a side of the cover.
21. A bioreactor system, comprising:
a sample chamber capable of receiving a specimen;
a cover which can be placed on the chamber to close the specimen within the chamber, the chamber including a port which allows liquid to be inserted into the chamber, the chamber being placeable in (i) a first position in which a long axis of the chamber is substantially vertical, and (ii) a second position in which the long axis of the chamber is substantially horizontal, the port being located and oriented so that the chamber can be substantially filled with liquid via the port when the chamber is positioned in either of the first and second positions; and
a lip extending from a portion of the sample chamber and configured to engage at least a portion of the cover along a side of the cover to resist the cover in moving in at least one direction.
22. The bioreactor system of claim 21 , wherein the chamber is placeable in a third position in which the long axis of the chamber is substantially horizontal and the chamber has been rotated about ninety degrees about the long axis from the second position, whereby when the chamber is in the third position the chamber can be substantially filled with liquid via an opening in the chamber that is exposed when the cover is removed from the chamber.
