The Whatman Mini-UniPrep G2 is an all in one device that functions both as a filter and a glass autosampler vial for sample preparation prior to UHPLC/HPLC. Liquid stored in glass, reducing leaching (specially with organic solvents) Works well for aqueous based samples. Sample only contacts plastic during the actual act of compression.
Our Omnipore membrane is a hydrophilic PTFE membrane that is compatible with virually all solvents, acids, and alkaline solutions. Features & Benefits: - Biologically and chemically inert. - High porosity yields high flow rates. - Hydrophobic and hydrophilic PTFE varieties available for filtration of aqueous and organic-based samples.
Whatman™ Uniflo™ Syringe Filters are disposable filter units designed to provide clean filtrate from small volumes up to 100 mL. They are available in a variety of membrane choices with a polypropylene overmold housing, and include both sterile and non-sterile options. 13 mm, 25 mm or 30 mm diameters 0.2 μm or 0.45 μm pore sizes See full list on cytivalifesciences.com
The size of membrane pores determines which particles will be retained by the filter. A pore size of 0.2 µm is small enough to remove microbes from solutions; a 0.45 µm ore size can remove larger particulates. Color and Grids. White membrane filters may be plain or marked with square grids (outlined in black) that can help with enumerating

PTFE is the membrane of choice for use with aggressive solvents, liquids, and gases that can attack other membranes. It is resistant to most acids, alkalis, and solvents. One of the major applications for the PTFE membrane is the clarification of corrosives, solvents, and aggressive fluids.
Choice of 4 mm, 13 mm, and 30 mm syringe filter diameter to suit sample volume Range of pore sizes for retaining a variety of particles Optional sterile, medical-grade blister pack Optional tube-tip format for accurate dispensing into a micro-vial Recyclable after use. Learn how you can recycle it.

2. Decide an appropriate pore size. The pore size of a filter, stated in microns (aka micrometers or µm), is determined by the diameter of particles retained by the filter or by a bubble point test. • Nominal ratings are the pore size at which a particle of defined size will be retained with an efficiency below 100% (typically 90-98%)
