In general, polypropylene is chemically less resistant than polyethylene. Polypropylene offers good resistance to non-oxidizing acids and bases, fats and most organic solvents. At elevated temperature, polypropylene can be dissolved in nonpolar solvents such as xylene, tetralin and decalin. The melting point of polypropylene is 160°C / 320°F)
Immerse in a 10 percent concentration of hydrofluoric acid for ten minutes, followed by ignition cleaning in a muffle furnace, following the guidelines given above. This can allow for reuse of membrane up to 10 times. Ultrasonic Cleaning Low intensity ultrasonics can be used to clean the silver metal membrane.
2022 new GH Polypro membrane lower hold-up volume (PDF) NOVEL MIXED MATRIX MEMBRANE FOR GAS MIXTURES SEPARATION The silicone-coated hollow fibres exhibit O2 permeance of 20–30 GPU and O2/N2 selectivity of 5–6.5 at 25 °C.
4.5.5 Column Hold-Up Volume. The system hold-up volume is defined as the volume of mobile phase contained within the chromatographic system between the injector and the detector [690]. It can be determined by the elution volume of an unretained and unexcluded solute. The column hold-up volume is equivalent to the system hold-up volume less the

The membrane consists of stainless steel with 'waffles' to absorb the thermal contraction when the tank is cooled down. The primary barrier, made of corrugated stainless steel of about 1.2 mm (0.047 in) thickness is the one in direct contact with the cargo liquid (or vapour in empty tank condition).

Hold-Up Volume Another aspect of choosing the right filter size is the hold-up volume. This is the volume of liquid remaining in the filter after use. A filter with a low hold-up volume is recommended for use with expensive fluids or those with limited availability.
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.
Membrane Bed Volume. 0.18 mL. Pore Size. 0.8 µm. Hold-up Volumes - 25 mm. 0.1 mL. Maximum Temperature. 70-75 °C. Maximum Pressure Limi -25 mm.
Polypropylene Syringe Filters. Sterlitech Polypropylene Syringe Filters are used in a wide array of analytical and research applications for the pharmaceutical, environmental, biotechnological, and agricultural industries. The design of these syringe filters allows them to perform filtration on aqueous as well as organic solvent based samples.
A microporous membrane (or coating) is a thin structure having a morphology of a precisely controlled interconnected network of tiny holes (pores) and an otherwise impermeable polymeric structure, the holes (or pores) being too small to allow water droplets to pass through, but large enough to allow water vapour to pass through.
