Description

Track-etched polycarbonate membranes
We manufacture Whatman track-etched membranes using proprietary technology to produce a precision membrane filter with closely controlled pore size distribution.
Cyclopore polycarbonate membranes
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.
Black Cyclopore membranes are excellent for epifluorescence and other microscopy applications requiring a contrasting background. The polycarbonate membrane is used to filter the sample and is then used directly for analysis. The dark membrane gives lower background fluorescence and improves the sensitivity of the test.
Features and benefits:
Low affinity for stains provides higher optical contrast, making visibility under a microscope easy.
True surface capture provides easy examination of samples and short analysis times.
Totally transparent membranes are available.
For the analysis of cell migration toward a chemical stimulus.
Thin and uniform; cylindrical pores facilitate rapid cell migration.
