Merck Express® Membrane

The Express membrane is first Merck membrane to deliver high flow for faster filtration, high throughput for increased retention, and low protein binding for minimal adsorption. This membrane is Ideal for use in many devices, especially 96-hour IV filters and other extended applications. It has low extractable levels and excellent sealing to most plastics.

Durapore® Membrane (PVDF)

This unique polyvinylidene fluoride membrane is one of the lowest protein binding membranes available, binding far less protein than nitrocellulose, nylon, or PTFE. Compatible with a broad range of chemicals, this membrane is available in a wide range of pore sizes. It's the same membrane that is used by pharmaceutical companies around the world for process filtration of pharmaceuticals.

MF-Merck Membrane

The most economical choice for basic aqueous filtration, the MF-{HCompany). provides excellent flow, throughput, and value. It is available in pore sizes from 0.025 to 8 µm.

Gemini Patterned Membrane Process

By combining hydrophilic and hydrophobic regions on one membrane, this unique process eliminates air-locking in filtration devices used for irrigation, suction, radiology, and imaging. The process can be applied to PES, PTFE, and PVDF membranes.

Irrigation and Suction

Filter units with Gemini-treated membranes can be used to dispense and suction fluids, such as irrigation fluids used during eye surgery.

Radiology and Imaging

Gemini membranes eliminate handling of air-locked units during filtration of radioactive or other potentially harmful solutions.
