Pall Metrigard Filter this depth-type filter medium is useful in a variety of general filtration applications, including replacement of asbestos filter pads. Pall Metrigard Filters is made of finer glass fiber than standard prefilters, with 5% acrylic binder. Pall Metrigard Filters liquid nominal rating: 0.5µm.
PTFE, nylon, PVDF, and wwPTFE membrane to be low in UV absorbing extractables. They have been tested for compatibility with common HPLC solvents (water, acetonitrile, and methanol) using established HPLC procedures. Filtrate from a statistical sampling of Acrodisc PSF syringe filters was collected and
Jan 01, 2009 · Retention efficiency testing reveals that when 0.05% 0.45um latex-sphere solution is filtered through a specialty syringe filter with GHP membrane and injected into an HPLC system, the column life is extended more than 40 times and column back pressure does not increase – even after 972 injections.
(polyethersulfone), and GHP (polypropylene) membranes, as well as Omega™ (modified polyethersulfone) ultrafiltration membrane in a variety of MWCOs. Prevent solution bypass– Membrane seals stop solution leakage, minimizing sample loss. Easy visual identification– Devices are color-coded for a wide variety of membranes, ranging from 1 kD to 0.45 µm.
Hydrophilic membranes, which have an affinity for water, are preferable when filtering aqueous samples. Use MS filters with GHP, PES, Nylon, or PVDF membranes. Gases and Aggressive Organic Solvents Hydrophobic membranes repel water and are inert to aggressive organic solvents, making them ideal for gases and organic solvents.
species, but there is a risk that some flavor or aesthetic elements of the product will also be captured by membranes with 0.22 micron pores. For that reason, 0.45 micron membranes are used by many bottlers.

of filter media: hydrophilic nylon membrane for excellent chemical compatibility with esters, bases, and alcohols, without pre-wetting; GHP (hydrophilic polypropylene) membrane for low protein binding; and hydrophilic PVDF (polyvinylidine fluoride) membrane for use in aqueous and non-aggressive,
Polymeric membranes are a common option for use in the capture of CO 2 from flue gas because of the maturity of the technology in a variety of industries, namely petrochemicals. The ideal polymer membrane has both a high selectivity and permeability. Polymer membranes are examples of systems that are dominated by the solution-diffusion mechanism.
The use of microfiltration membrane bioreactors (MBRs), a technology that has become increas-ingly used in the past 10 years, overcomes many of the limitations of conventional systems. These systems have the advantage of combining a sus-pended growth biological reactor with solids removal via filtration. The membranes can be

The GHP membrane used in Pall Laboratory Acrodisc® syringe filters, centrifugal devices and Acroprep™ filter plates will be discontinued due to the rationalization of a key material from our supplier. However we are excited to . More Product Information.
GHP membrane to be low in UV absorbing extractables. They have been ®tested for compatibility with common HPLC solvents (water, acetonitrile, and methanol) using established HPLC procedures. Filtrate from a statistical sampling of Acrodisc PSF syringe filters was collected and run under gradient mobile phase conditions at three common wavelengths. The
Using Membrane Solutions syringe filters with GHP (hydrophilic polypropylene) membrane is the most efficient way to remove particulate and prolong the life of HPLC system components. Membrane Solutions’ syringe filters with GHP membrane are widely used for this purpose. The average retention efficiency of 0.45 µm rated syringe filters with
