Abstract
A tissue culture holder has an insulating chamber in its base below the culture containing chamber or chambers. The insulating chamber is filled with air or a clear liquid and may be sealed in a low humidity environment so that, in the case of an air-filled chamber, there will be minimal or no condensation in the chamber. In the case of a multi-well tray, the insulating chamber below the wells may be sealed or may have passageways for circulating air through the chamber and up into the space above the wells.

A tissue culture holder, comprising:
- a relatively flat container having at least one culture chamber for containing a reagent under test a relatively flat cover for said container, and a separate insulating chamber below the culture chamber for insulating the culture chamber, the insulating chamber having a transparent bottom wall for allowing viewing of the contents of the culture chamber from beneath the holder, and the depth of the insulating chamber between the bottom wall of the culture chamber and the bottom wall of the insulating chamber being no greater than 5/16 inch.
A tissue culture holder, comprising;
- a flask of elongate, bottle-like shape having a narrow neck portion at one end and a wider, body portion extending from the neck portion and terminating in an end wall;
- a dividing wall extending along the length of the body portion parallel to the central longitudinal axis of the flask up to the end wall to divide the body portion into a culture chamber for containing a reagent under test and a separate insulating chamber;
- the culture chamber communicating with the neck portion of the flask and the insulating chamber being sealed and having a depth of no greater than 5/16 of an inch between the dividing wall and a side wall of the flask.
