Cleaning agents are used on walls, ceilings, floors and equipment in the cleanroom. A well-rounded systematic approach to choosing, evaluating and using cleaning agents is critical to maintaining control of contamination.
Sterile alcohols
 |
The TexShield Sterile 70% Isopropyl Alcohol and Sterile 70% Isopropyl Alcohol with water for injection (WFI) are easy and safe to use, cost effective, and maintain their sterility assurance level throughout prolonged normal use. The bottles are recyclable and the contents can be completely dispensed. The TexShield alcohol products are all packaged using the SteriShield Delivery System (patent pending). This system holds the liquid inside an ultra-clean, medical grade, polyolefin bag that does not allow air to be drawn back into the bag when the trigger spray mechanism is operated. Testing shows the contents remain sterile for three months after first operating the trigger. Packaged in one-liter and five-liter containers, the sterile alcohols are useful for surface cleaning, cleaning gloved hands in sterile suites, and wiping down items for pass through into a controlled environment.
