This is a 50-pack of bottle cap cases for Wheaton BOD water bottles. The cases have a closed cell foam insert that fits over the flared mouth of the water bottle, and they have a snap closure to prevent the evaporation of the water seal.

Wheaton BOD Bottle Cap, complete with a closed cell foam insert, snaps firmly over the flared mouth of Wheaton BOD bottles. This closure prevents the evaporation of the water seal during the five-day BOD incubation period. The foam insert fits into the cap and exerts pressure on the bottle stopper to hold it securely in place.
