Hydrophilicity of Cyclopore polycarbonate film

Track etched polycarbonate film

Whatman ™ Track etching film is a high-precision film manufactured using technology, with a narrow pore size distribution and high pore size consistency within the film.

This series of membranes includes Cyclopore polycarbonate, Nuclepore polycarbonate, chemotactic membranes, black polycarbonate, and polycarbonate membranes used for cell culture.

Cyclopore polycarbonate film

Whatman ™ Cyclopore membrane is a microporous membrane with a true pore size, characterized by the sharp cutoff of etched membranes and the reproducibility of microfiltration efficiency. The surface of the membrane is smooth and flat, ensuring that particles remain on the membrane surface for easy microscopic observation.

The filter membrane is made of pure polymer membrane, with high chemical cleanliness, no pollutants and impurities, low tare weight, low water absorption, and low non-specific protein adsorption level. Polycarbonate film is hydrophilic and can be selected in different pore size specifications and size specifications.

• Analytical methods

Weight method analysis, density measurement method, emission spectroscopy, X-ray fluorescence method, and infrared analysis method

• Water analysis

Absorbable organic halogens (AOX), direct counting of microorganisms, marine biology, and analysis of soluble phosphates, nitrates, and ammonia

• Blood filtration and cell analysis

Red blood cell deformability, removal of white blood cells, red blood cell filtration and plasma extraction, chemotaxis, cytology, and cell culture

• Ordinary laboratory filtration

Particle and bacterial removal, lateral flow filtration, HPLC sample preparation, and solution filtration.

• Microscopic observation

Electron microscope, epifluorescence microscope, and optical microscope.

Microbial analysis

Direct counting, harvesting, concentration, and grading of total microbial count (yeast, mold, Giardia, Legionella, Escherichia coli, and canine microfilaments)

• Nucleic acid research

Alkaline elution and DNA fragment fractionation.

• Oceanography research

The transparent polycarbonate film provides a tool for studying plankton. These ultra-thin transparent membranes are sturdy and flexible, capable of filtering plankton samples while also being directly mounted onto microscope slides.

• Medical and Health

Biosensors - can act as biological reagents and electrochemical detector membranes to control diffusion

Diagnostic analysis - used for flow control, sample preparation, blood separation, and latex particle capture

Cell Biology - Used for cell culture, chemotaxis, and cytological analysis (such as direct staining, isotope and fluorescence analysis).
