Jun 01, 2015 · Certified contaminated extract: prior to experiments, the extract from certified peanuts previously treated by HPLC (Section 2.3) was centrifuged and then filtered by 13 mm diameter sterile syringe filter with a 0.22 μm pore size hydrophilic PVDF membrane (Millex-GV, Merck Millipore, Germany), before being used in biosensing measurements.
This 33 mm syringe filter with a Hydrophilic Polyethersulfone membrane, for non-sterile filtration on the Samplicity G2 system, has a 0.22 µm pore size used in preparation of aqueous solutions prior to chromatography or other instrument analyses.

Sep 01, 2008 · Intermediate standards were prepared by filtering approximately 3 mL of the stock solution through a 0.22 μm syringe filter into a 100 mL volumetric flask. Approximately 80 mL of ethanol was added and the flask sonicated for 5 min, then made to volume with ethanol.
with ethanol (100-fold dilution). Using a glass syringe fitted with a 0.45 μm regenerated cellulose (RC) syringe filter (part number 5190-5107), filter 2 mL of the solution into a clean glass vessel. Perform an additional 10-fold dilution of the filtered solution by transferring a 100 µL aliquot into an
Syringe filters. Filters Syringe Filters. 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

Membranes Designed for the StringentRequirements of Mobile Phase Filtration. Membranes are identical in composition and quality to those used in Pall’s HPLC-certified Acrodisc ® syringe filters. HPLC certification assures that the filters will not add artifacts to your analysis. GH Polypro membrane is the best choice for filtering mobile phases.
Syringe Filter The DMSO-Safe Acrodisc syringe filter provides chemical compatibility in a sterile device for filtering DMSO and other harsh solvents. Ordering Information Part Number Description Packaging 4433 0.2 µm, 25 mm 50/pkg Certification Pall Life Sciences certifies the enclosed disposable filters are: 1. Sterile, non-pyrogenic, and non
Depending on the application, Sarstedt offers products for vacuum filtration (Filtropur V/BT) and pressure filtration (Filtropur L), as well as syringe filters (Filtropur S/S plus). Large filtration areas with or without integrated pre-filters can be used for volumes between 1 ml and 10 l, depending on the application.
· Nylon Syringe Filter is used for most organic solvents mixtures and mid-polar liquids. It is suitable for chemical filtration and beverage filtration. · Welded type nylon syringe filter is made of nylon + PP pre-filter, it provides two times greater throughout than standard filter without pre-filtration.
