Cappers™ - Caps for evacuated blood drawing tubes

Cappers™ effectively recap blood drawing tubes, glass test tubes and plastic culture tubes. They help protect samples from cross-contamination and highly infectious aerosols such as TB and the HTLV-III virus. Precision molded from low density polyethylene, with a double flanged seal, Cappers™ fit securely on the tube. They maintain a tight closure during such procedures as agitation, centrifugation and refrigeration. The unique dual thumb tab facilitates effortless cap removal. Available in 4 sizes for the ideal resealing of most evacuated blood collection tubes. Each size is available in seven different colors for coding of specimens or for modern laboratory aesthetics.
