Serum Sample Cup Caps

Caplugs® Evergreen Serum Sample Cup Caps come in two different styles, flat top and perforated top, and are designed to fit all types of Standard Serum Sample Cups. Flat top caps are appropriate for short-term storage, while perforated top caps help minimize variation caused by evaporation during processing.

• Caps can also be used for our Unthreaded False-Bottom Tubes
