Concavity Slides, Plastic, 3 x 1", 18 x 3-mm Well, Pack of 10

I simply taped these to a standard glass slide to use the stage holder,otherwise they are too thin for proper scanning. The raised wells prohibit using higher power objectives for viewing. I also used a very thin bead of clear silicon tubseal to mount a coverslip and create a "permanent" slide of perserved specimens for future references and practical exams.

I bought these with the Planaria, Daphnae and Hydra Kit. We used them to observe all three creatures under the scope. It is deep enough to allow the organisms to interact and at a very affordable price.

The concave slides worked well with our water study
