Structure of filter

Air venting
IV filters are a product that protects patients from infusion of air, which guards against an air embolism due to entrapped air. Air vents are made of hydrophobic PTFE membrane. The large surface area in all the three size of the vents allows air elimination.

Hydrophilic membrane
The PES membrane is an highly asymmetric membrane which ensures high flow rates and long life with no plugging. Flow rate values are depending on specific applications. Thanks to its geometry, IV filters minimizes the “dead area” providing a further advantage in applications requiring high flow rate. The low residual volume reduces the quantity of solution lost into the IV line.
Drug adsorption is a key point when using IV filters in drug delivery, thanks to its low binding performance, the PES membrane which equips the IV filter minimizes the adsorption of drugs reducing the cost for loss of drug during infusion.

Endotoxin Removal
Endotoxins are chemicals produced by the breakdown of bacteria. If endotoxins are allowed to enter patients systemically, they can cause fever and infections. Endotoxins are negatively charged.
Standard IV filters cannot remove them from solutions, however, if the membrane is positively charged, it attracts the endotoxins. The filter 0.2 with positive charged membrane attracts and retains endotoxins.

Housings
Standard Housing: clear or in different colors.
Housing for Photosensitive Drugs: filter with amber housing is available for drugs that are sensitive to UV light.
