China Suppliers Factory Custom Hydrophobic PTFE Membrane Filter for Insufflation Gas Filtration with 99.99% Bacterial Removal
Product Introduction
The use of an insufflation gas filter helps prevent the contamination of equipment by miscellaneous debris that may be present in normal gas delivery. Such a filter also protects the insufflator should abdominal fluid or debris back up into the line. And the key to the optimal operation of an insufflation filter is for the PTFE membrane integrated in it to provide robust bacterial removal efficiency and meanwhile not to restrict flow to the patient.
The safe hydrophobic PTFE membrane filters we supply, offer 99.99% bacterial removal efficiency, helping prevent cross-contamination between patients and equipment, and protects against the dangers of reflux fluids from patient into the insufflator unit, offering both machine and patient protection.
The custom designed PTFE filter media, using PP/PET as substrates, employs a double-sided thermal bonding process, binder-free and contains no toxic substances. In addition to the general properties of PTFE membranes, such as naturally hydrophobic, biologically safe and great material compatibility, the laminated membrane features two-side hydrophobic PTFE, which means both faces of the membrane are PTFE, with exactly the same physical properties and desired performance, making both faces suitable for being used as working face and reducing assembly mistakes. This PTFE laminated membrane is reinforced and durable with a maximum service-life of 24 hours and meets various operating conditions. Easy and convenient for further processing and assembly, available in roll and precut circle forms.

Frequently Asked Questions (FAQ)
Q
What is the bacterial removal efficiency of the PTFE membrane?
The hydrophobic PTFE membrane filters offer a 99.99% bacterial removal efficiency, helping prevent cross-contamination between patients and equipment.
Q
What are the benefits of a two-side PTFE membrane design?
Both faces of the membrane have the exact same physical properties and performance. This means either side can be used as the working face, which significantly reduces mistakes during assembly.
Q
What is the maximum service life of this PTFE laminated membrane?
This reinforced and durable PTFE laminated membrane is designed to meet various operating conditions with a maximum service life of up to 24 hours.
Q
How should the PTFE filter membrane be attached to its housing?
Do not use glue or cyclohexanone for joining the membrane to the housing, as these substances will clog the material and block gas flow.
Q
Can the PTFE membrane be sterilized using irradiation?
No, sterilization by irradiation is not recommended for this material.
Q
What forms are available for ordering this membrane material?
The membrane is designed for easy post-processing and assembly, and is available to order in both roll and precut circle forms.
