Cyclopore PC Polycarbonate Membrane, Circle

Whatman Cyclopore PC Polycarbonate membranes are true pore size microporous membranes featuring the sharp cut-off and reproducible microfiltration performance characteristics of track-etched membranes.

• Low affinity for stains provides higher optical contrast and makes visibility under a microscope easy.
• True surface capture provides easy examination of samples and short analysis times.
• Totally transparent membranes available.
• Negligible absorption and adsorption of filtrate; nonhygroscopic.
• Low tare weights.
• No particle shedding provides ultra clean filtrate.
• Biologically inert.

The smooth flat membrane ensures particles are retained on the surface so that they are easily visible under a microscope.

Cyclopore membranes are manufactured using proprietary Whatman technology to produce a precision membrane filter with a closely controlled pore size distribution.

Membranes are produced from a pure polymeric film and give exceptional chemical cleanliness. They are free of contaminants, have low tare weight, minimum water adsorption, and very low levels of nonspecific protein binding.

The polycarbonate membranes are hydrophilic and are available in a choice of diameters and pore sizes.
