Pall provides two types of non-sterile Acrodisc® syringe filters with Versapor® membrane
Acrodisc syringe filters with Versapor membrane, modified acrylic housing
Acrodisc syringe filters with Versapor membrane,, Polypropylene housing
Versapor is an acrylic copolymer on a non-woven support membrane. The hydrophilic membrane offers excellent throughput with high liquid flow rates making these syringe filters ideal for clarification, prefiltration or the filtration of high particulate laden samples.
Non-sterile syringe filters with Versapor membrane in modified acrylic housing can be used for the filtration of general aqueous solutions, clarification and prefiltration. They are available in a 25 mm diameter, offering an effective filtration area of 2.8 cm2. A range of different pore sizes from 0.45 μm to 5 μm are available to suit different application requirements.
The Versapor syringe filters with polypropylene housing are ideal for use in analytical chemistry filtration applications, such as analytical chemistry sample preparation, dissolution testing, or other techniques in which an acrylic copolymer membrane has been specified. The polypropylene provides a robust and chemically inert housing.
These syringe filters are available in a 4 mm, 13 mm and a Premium Syringe Filter (PSF) 25 mm diameter to suit different volume filtrations.
0.45 μm, 0.8 μm and 10 μm versions of the syringe filters are available. The large 10 μm pore size, makes this syringe ideal to use in prefiltration applications for solutions that have a very high particulate load.
The PSF 25 mm filters have been designed and certified to meet the exacting requirements of automation systems. They demonstrate critical criteria including smooth filter-to-filter release, consistent turret advancement, exceptional housing strength and a strict outside filter geometry to ensure proper alignment and consistent operation. AutopackTM tube packaging is available for compatible automated equipment.
