Standard Stopper Caps

Caplugs® Evergreen Standard Stopper Caps are available in a wide variety of sizes and colors to fit your desired test tube, providing a proper closure with a secure seal. These stopper caps feature a deep recessed top and fine ridges on the sides to be grasped and removed from the test tube easier. This version of our stopper cap also allows for laboratories to reduce their transport costs due to reduced weight that derives from the concaved aspect of cap's design.

• Accommodatable test tube sizes range from 8 mm to 17 mm
