For test tubes:

  • Precision-molded stopper caps are available for every size (except 15.5 × 50mm) of Evergreen test tube.
  • Choose from either standard caps (like the 300-2900 series) or the flat-top style (300-4700 series).
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 (Cat. No. 05-551-5) help minimize variation caused by evaporation during processing; non-perforated caps and push-button stoppers are appropriate for short-term storage.(Cat. Nos. 02-544-73A and 05-300-291)
