Chlorophenol red water detection paper sheets are a fast & convenient way to find leaks quickly in multihole/multiwell spot plates. The spot plate can be placed on top of the 8x10" sheet (200x250mm) which in turn can be placed on top of a vacuum plate. By pulling a light vacuum, small leaks in individual wells can be identified quickly.
This test can also be done with the cobalt chloride & universal pH sheets; see Related Products below.
