Description
Key Features
Material: The filter is made from a mixture of cellulose acetate and cellulose nitrate, commonly known as mixed cellulose esters (MCE). This material is chosen for its low protein binding and resistance to chemicals like alcohol and oil.
Pore Size: 0.025 µm (micrometers). This ultra-fine pore size is suitable for very precise filtration and particle retention.
Wettability: The filter is hydrophilic, which means it easily gets wet with water and other aqueous solutions.
Dimensions: It is a disc filter with a diameter of 25 mm and a thickness of approximately 100 µm.
Low Extractables: The VSWP02500 filter is manufactured without the Triton surfactant, resulting in a lower level of water-extractable content compared to standard MF-Millipore filters. This is important for applications where minimizing contamination is crucial.
Sterilization: It can be sterilized using several methods, including autoclaving at up to 121∘C, ethylene oxide, or gamma irradiation.
Other Specifications:
Color: White
Surface: Plain (non-gridded)
Maximum Operating Temperature: 75∘C
Porosity: 72%
Flow Rate: Water flow rate of and an air flow rate of .
Uses
The combination of its fine pore size, low extractable content, and MCE material makes the VSWP02500 filter a versatile tool for several laboratory applications:
Microdialysis of DNA and Proteins: It is particularly suited for a technique called "drop dialysis," which is a method for the rapid desalting and recovery of small-volume samples () of protein or nucleic acid solutions.
Sterile Filtration: With its very small pore size, it can effectively remove biological contaminants like bacteria, molds, and yeasts from various liquid samples, including nutrient media and buffers.
General Laboratory Filtration: It is used for general-purpose clarification and filtration of aqueous solutions.
Analytical and Environmental Monitoring: The filter is employed in applications that require the retention or removal of biological contaminants and particles from samples for subsequent analysis.
