Tetpor HP

TETPOR HP filter cartridges have been specifically designed to minimise preservative binding for economic sterilisation of multidose ophthalmic solutions.

Tetpor HP

Preservatives are present in low concentrations in ophthalmic solutions and therefore any adsorption onto a filtration membrane can complicate the manufacturing process. Ensuring preservative levels are maintained requires a validated method of preconditioning the filters prior to processing which can be time consuming and costly in terms of product wastage.

The unique hydrophilic PTFE membrane featured in the TETPOR HP exhibits lower levels of preservative binding than other membrane types such as PES and PVDF and can practically eliminate the adsorption of preservatives from ophthalmic solutions.

Features & Benefits

  • Eliminates preservative binding preventing product loss and process downtime
  • Incorporates a fully validated and integrity testable 0.2 micron membrane for assurance of sterility
  • Fast flowing membrane for increased process efficiency
