Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
A dissecting tray comprising: (1) tank means for containing dissecting fluid, (2) a horizontal rigid platform in said tank means below the fluid level for supporting a specimen during dissection and mounting means for supporting said platform, (3) a fluid supply means in a first side wall of said tank means for supplying dissecting fluid to said tank means near the fluid level, and (4) drain means including a fluid pickup in a second side wall of said tank means opposite said first sidewall and near the bottom of said tank means for maintaining the fluid in said tank means at a constant level while said fluid is being supplied, and wherein said fluid supply means and said drain means are arranged and constructed such that a one way passage of fluid can be maintained horizontally across said platform to keep said platform immersed in a bath of fresh fluid.

The dissecting tray of claim 1 wherein said drain means has a greater flow capacity than said fluid supply means.
Claim 5
Dependent Claim
23 words
The dissecting tray of claim 1 wherein said tank means includes an opening at the top to permit easy access to said platform.
Claim 6
Dependent Claim
35 words
The dissecting tray of claim 1 wherein said drain means includes a conduit rising from said fluid pickup to the level of fluid in said tank means for maintaining the fluid at a constant level.
Claim 7
Dependent Claim
35 words
The dissecting tray of claim 5 wherein said drain means further comprises an opening in said conduit adjacent said fluid level to act as a siphon break to prevent said tank means from draining completely.
