Abstract
Provided are devices for measuring the exposure of a tissue sample to a treatment medium, wherein the device provides for inspection without direct inspection of the tissue sample. The inspection may comprise visual inspection of the device. Treatment containers comprising these devices and methods of use of the devices and treatment containers are also provided.
Claims31
A device for measuring an adequate exposure of a tissue sample to a treatment medium, wherein visual inspection of the device after the device and the tissue sample are contacted with the treatment medium provides for measuring the adequate exposure without direct inspection of the tissue sample, the device comprising:
- a) a compound operable to change a perceived colour of the device when the compound is adequately exposed to the treatment medium;
- b) a surface for supporting the compound;
- and
- c) a transparent body connected to the surface, the transparent body being impenetrable by the treatment medium and being operable to control contact between the compound and the treatment medium when in the treatment container, wherein the compound is protected from complete immediate exposure to the treatment medium by being between the surface and the transparent body.
A device for measuring an adequate exposure of a tissue sample to a treatment medium, wherein visual inspection of the device after the device and the tissue sample are contacted with the treatment medium provides for measuring the adequate exposure without direct inspection of the tissue sample, the device comprising:
- a) a foam layer;
- b) a film layer coating at least a portion of the outside of the foam layer;
- c) a density increasing agent;
- d) a softening agent;
- and
- e) at least one foam stabilizing agent.
A device for measuring an exposure of a tissue sample to a treatment medium, wherein visual inspection of the device after the device and the tissue sample are contacted with the treatment medium provides for measuring the exposure without direct inspection of the tissue sample and the visual inspection comprises a change in a position of the device relative to a top surface of the treatment medium.
The treatment container of 29 wherein the treatment container is a flask, a Petri dish, a test tube, bottle, jar, tub, bucket, cassette, a specially designed container for tissue sample processing, a specially designed container for tissue sample handling, or a specially designed container for tissue sample storage.
