FOR TEST TUBES

Precision-molded stopper caps are available for every size (except 15.5x50 mm) of Evergreen test tube. Choose from either standard caps (like the 300-2900 series) or the flat-top style (300-4700 series). 300-2900 series caps for 12 mm tubes are available in six colors.

FOR CULTURE TUBES

Over-fitting caps for use with sterile culture tubes have two positions: loose for aerobic culturing; tight for anaerobic culturing and leak-proof sealing. Caps for culture tubes are gamma-irradiated for sterility.

FOR SAMPLE CUPS

Perforated caps help minimize variation caused by evaporation during processing; non-perforated caps are appropriate for short-term storage.
