A tight seal ensures sample integrity and prevents spillage or evaporation of serum samples

Caps fit all varieties of blood collecting and disposable culture tubes. They are color-coded for easy specimen identification and to help guard against cross-contamination. Top of cap can also be numbered or labelled with indelible ink. Self-locking caps hold firmly in any position and keep contents secure while travelling. Liquid-tight seal withstands centrifugation, agitation, refrigeration, and freezing. Manufactured from polyethylene.

This special seal protects against the aerosols of highly infectious organisms such as TB and the HTLV-III virus.
