Clear polycarbonate lift-off gable lids, to reduce evaporation, reduce risk of sample contamination and save energy. These clear plastic lids have a high profile, allowing extended use of the bath right into the edges of the tank, with no drip points to contaminate samples. Lid design ensures condensate runs back into the bath. Includes insulated handle. Lids fit all Clifton NE1, NE1-D and NE2-D unstirred baths. The 4L size also fits the Triplebaths.
