Double Emulsions. Micropore’s range of advanced crossflow equipment is a unique system that utilises consistent physics, mechanism, conditions and geometry across a range of devices enabling development using a micro device with 100,000 pores delivering as little as 1ml which can be simply accelerated to deliver 20 litres of formulation per hour.
Pall GHP Polypropylene membrane will be discontinued effective October 31st, 2019. This discontinuation affects devices including syringe filters, filter plates, centrifugal devices and membrane filter discs. Syringe filters are attached to the end of a syringe to remove particles from a sample prior to analysis. Filtering liquids, the single-use devices force liquids through the filter either
This syringe filter is made with GHP (hydrophilic polypropylene) membrane for low protein binding and features a polypropylene housing with female Luer-lock inlet and standard male slip Luer outlet connections. The membrane is HPLC certified for low levels of UV-absorbing extractables. Membrane: GHP Membrane. Pore Size: 0.45 µm. Typical hold-up volume: \\<100µL. Pall Life Sciences #: 4560.
Introduction. Membrane filters or “membranes” are microporous plastic films with specific pore size ratings. Also known as screen, sieve or microporous filters, membranes retain particles or microorganisms larger than their pore size primarily by surface capture. Some particles smaller than the stated pore size may be retained by other.
A hefty percentage of the upstream volume can be collected from the process. Downstream hold up volume is harder to recover. One of the conventional ways is to drip it out from the filter outlet. International Filter products offers filters with low retention rates that reduces the hold-up volume significantly.

Send. During filtration, all systems retain some liquid that cannot be recovered. This is called “hold-up” volume. The larger the hold-up volume, the greater the loss of media and reagents. However, the Upstream “Hold up” Volume can be recovered by pumping air through the vent. A hefty percentage of the upstream volume can be collected
The purpose of encasement is to retain a high cell concentration inside the certified syringe filter (GHP Acrodisc 13 mm with 0.2 μm GHP membrane) to Understanding syringe filters - Andy Connelly. Sep 28, 2016 A filter with a low hold-up volume is recommended for use with expensive fluids or those with limited availability.
