The "Universal" Membrane Filter for all of your Analytical Filtration Requirements.

Positive pressure 96-well plate sample processing with Presston 1000 offers an advanced alternative to traditional vacuum manifold processing. To offer a wider applicability, Presston 1000 is equipped for processing samples in both a low pressure setting for typical solid phase extraction steps and a high pressure setting for very viscous sample processing and for sample dry down.  In addition, Presston 1000 is compatible with…

Certified 0.45 µm membrane for microbiological analysis meets or surpasses regulatory specifications Mixed cellulose esters is the most accepted filter media for microbiological analysis, and provides maximum recovery of organisms. Unique dot grid pattern gridline provides guidance for quantification of bacterial colonies without growth inhibition or enhancement. Suitable for microbiological analysis using the Membra…

Available with either cellulose acetate or PES membrane. Sterile membranes with 0,2 µm pore size are ideal for sterile filtration applications, whilst those with 0,45 µm pore size can be used for clarifications. These sterile syringe filters are gamma irradiated to prevent cytotoxic residues caused by alternative sterilisation methods. According to USP Class VI   Cellulose acetate membrane surfaces are not treated…

Luer lock inlet offers leak-tight syringe connection. Variety of filter types, porosities, and diameters. Color coded for easy identification. Rugged polypropylene housing. Autoclavable to 121 °C for 15 minutes. Quantity break pricing for greater savings.

Individually Packed, 100/pk Part Number: SFS-AR-1025

Use with any standard male luer end SPE cartridges. Inert, PTFE sample guides reduce cross-contamination and carryover. Flexible sample collection rack will accommodate a variety of receiving vessels. Quick vacuum-release valve for better system control. Individual valves allow vacuum control for each cartridge, improving reproducibility.

Our Vyon® porous media is manufactured from USP Class VI approved HDPE or PP materials, making it particularly suitable for both food and pharmaceutical applications. It has a uniform pore structure giving an even total area fluidisation.

Perform sterile filtration of cell culture media, serum, additives and buffers with Thermo Scientific ™ Nalgene ™ Rapid-Flow ™ Sterile Disposable Bottle Top Filters with PES Membranes.

Omega has been manufacturing UV filters for over 50 years. UV light (in the 200 nm - 400 nm range) has many commercial and consumer-level applications. UV light can be used in photolithography or dentistry to photoset polymers, and in biomedical applications to excite molecules during surgery. It can be used to measure DNA and to sterilize our water and the air we breathe. While useful for many things, it can also be harmful.…
