Vacuum Plasma Treatment for Test Tubes

Vacuum Plasma Treatment for Test Tubes

Test tubes surfaces can be subjected to vacuum plasma treatment to change their surface energy by either making them hydrophilic or hydrophobic. Along with modifying the surface energy plasma also act as an sterlizer which tends to kill the bacteria and germs present inside the test tubes which can further contaminate the fluid or drug going to be filled inside it.

Improved adhesion of biomolecules to the tube surface, such as antibodies or antigens in diagnostic assays, is one frequent use of vacuum plasma treatment for test tubes. By forming reactive spots on the surface, such as hydroxyl (-OH) groups, the plasma treatment can enhance the biomolecules' adherence to the tube surface by forming chemical bonds with them.

Also, the test tube surface can be cleaned with vacuum plasma treatment to get rid of any impurities that might tamper with analytical data or lead to experimental errors. Organic residues, dust, and other surface contaminants can be successfully removed by the plasma, leaving behind a clear and hydrophilic surface.
