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.

I bought these for the purpose of locating hard to observe, intermittent water leaks. By strategically placing small sections of the paper in various places, I was able to monitor on a schedule rather than guessing when the leaks might happen. Now the leaks are fixed and I can monitor periodically for signs of new problems.

This water detection paper worked well in identifying moisture intrusion during testing and was easily observable due to its high color contrast.
