Filtration. Filtration and microfiltration are used to separate solids, particulates or large molecules from fluids (liquid or gases) in order to purify the filtrate. Explore a range of filter formats, including filter paper, plates and membranes for your separation needs. While larger particulates may be separated by gravity filtration
Available in 4, 13, 25, 33, and 50 mm diameters with a variety of membranes, Millex ® sterile syringe filters are ideal for sterilizing organic solvents, aqueous solutions or air/gas. Many sample preparation methods specify Millex® filters because of their unsurpassed quality and consistency. Millex ® filters not only feature minimal hold-up
Feb 17, 2020 · A syringe filter (sometimes called a wheel filter for its wheel-like shape) is a single-use membrane based filter cartridge, to be attached with a syringe to remove impurities in liquid solutions. This pre-filtration step is vital in preventing damage to instruments (e.g. liquid chromatography, ICP, etc.).
Pall’s sterile syringe filters are available with a variety of high-performance membranes to suit application requirements: Fluorodyne® II Membrane - For high flow rates and low protein binding. Not recommended for use with some ethers. Supor® Membrane - For high throughputs, fast filtration, and low protein binding.
The syringe generally does not take an active role in injection, which occurs only after the sample has been displaced from the syringe. These syringes are designed for the highest performance in applications such as liquid or gas chromatography and the handling of corrosive gases and liquids, radioactive materials, and sterile solutions.
filtered through a 0.45µm sterile syringe filter. The supernatant was loaded onto a 5-mL HisTrap (Ni2+) IMAC column and washed with 10 CV of wash buffer. Protein was eluted with elution buffer (50 mM KHPO 4 pH 7.0, 250 mM KCl, 500 mM imidazole, 10 % glycerol) over a gradient 0-100% over 10 CV.

POA. POA means "Price On Application". Items displaying POA instead of the sell price do so for a number of reasons, not least because we anticipate some additional information is required in order to supply the most suitable options/configuration to each individual customer.
Nalgene® 1000mL MF75 Sterile Disposable Filter Units with PES Membrane, ideal for vacuum filtration and single-use biological work requiring sterile filtration, prefiltration or clarification of aqueous solutions in the lab or field.
Jun 08, 2016 · Using a syringe pump containing 0.5 M sodium hydroxide in a 5 mL syringe the pH is slowly raised at a speed of 10 μL/min under constant stirring with a magnetic stirring bar in the solution until
Wells were pumped to get stabilized oxidation-reduction potential (ORP) values (commonly 10–15 min) prior to groundwater sampling. Microbial samples were collected by filtering of approximately 10 L fresh groundwater through 0.2-μm filters (Millipore), the filters were immediately packed into 50 mL sterile tubes, and then frozen in dry ice.
The top 5 instrument makers accounted for more than half the sales of the top 20 firms last year. Thermo Fisher Scientific alone accounted for 23% of the top 20’s instrument sales. The top 10 firms were responsible for 78% of sales, down from 79% in 2017. Combined sales for the top 10 grew 5.8% last year, whereas sales at the bottom 10 firms
Syringe filters for ion chromatography are available in 0.05 µm, 0.10 µm, 0.22 µm, 0.45 µm, 0.70 µm, 0.80 µm, 1 µm, 3 µm, 5 µm, and 10 µm pore sizes. If you need to extend the life of the filter or allow for increased flow during filter life, choose a syringe filter with a prefilter .
