Syringe filters are single-use, membrane-based devices used for the removal of particulate impurities from liquid and gas samples prior to analysis by methods such as HPLC, ion chromatography, gas chromatography, ICP, and dissolution testing. Proper filtration of samples improves the quality and consistency of analytical results and decreases instrument downtime.

n-Undecane for synthesis, Sigma-Aldrich®

Supplier: Merck

Sodium gluconate for synthesis, Sigma-Aldrich®

Supplier: Merck

These Immobilon® PVDF membranes, each optimised for different protein blotting applications.

Supplier: Merck

The filters without binder resin retain their structural integrity without weight loss when heated up to 500 °C and can therefore be used in gravimetric analysis as well as for the filtration of hot gases.

Supplier: Merck

Filters for sterilising or clarifying biological solutions. The larger filtration area increases flow rate and throughput. It also makes it easier to filter solutions because it reduces the pressure required to empty the syringe.

Supplier: Merck

Ideal for sterilising tissue culture media, buffers, or other aqueous solutions. The no tip, tapered receiver flask and compact profile of the Stericup® design improve stability and make gripping the receiver easier.

Supplier: Merck

Millex® Syringe filters are HPLC-certified for low levels of UV-absorbing extractables.

Supplier: Merck

Immobilon® Western HRP substrates are compatible with both PVDF and nitrocellulose membranes, as well as all commonly used buffers and blocking reagents.

Supplier: Merck

MultiScreenHTS plates are specifically developed for high-throughput use with automated work stations. Rigid sidewalls improve handling and ample surfaces are provided for bar code labels. Wells are individually sealed to prevent incubation crosstalk and the underdrain is removable for access to the filters. Filter plates are available in 96- and 384-well platforms with a broad selection of membranes and plastics.

Supplier: Merck

These centrifugal filter units can be used for a number of applications: concentration of biological samples containing antigens, antibodies, enzymes, nucleic acids, or microorganisms; purification of macromolecular components found in tissue culture extracts or cell lysates and protein removal prior to HPLS; concentration of dilute or pre-purified proteins from column eluents; desalting, buffer exchange and protein dialysis; size exclusion and protein fractionation.

Ultra centrifugal filters provide fast sample processing and promote high sample recoveries, even in dilute samples, through ultrafiltration.

Supplier: Merck

Filters for sterilising or clarifying biological solutions. The larger filtration area increases flow rate and throughput. It also makes it easier to filter solutions because it reduces the pressure required to empty the syringe.

Supplier: Merck

These filter holders are used to ultraclean or sterilise small volumes of liquids dispensed by syringes.

Supplier: Merck

Potassium permanganate ≥99.0% (by manganometry), EMSURE® ACS for analysis (max. 0.05 ppm Hg), Supelco®

Supplier: Merck

Centrifugal filter units concentrate samples in the range of 15 ml to 70 ml. The large dead stop volume of 350 µl prevents spinning samples to dryness. It has two vertical regenerated cellulose membranes for fast, efficient tangential flow.
