Purpose: For washing, coating and generally soacking 12 mm coverslips. This rack holds 25 coverslips. The trough is ~ 13.5 mm deep to allow complete immersion. 

Volume of trough: 5 ml . This equates to ~$2.5 worth of 50 µg/ml poly-L-lysine.

Printing: We print these with PLA with 2-layer side walls and 3 layer top and bottom. We print at 100 % fill to minimize absorbtion of solutions.
