• Concentrates 500 µL down to 15 µL• Concentration factor 25 x to 30 x• High sample recovery (greater than 90% of dilute starting solution)• Fast processing time - 10 to 30 minutes• Consistent recoveries thanks to the reverse spin capability• Reverse spin capability provides consistent recoveries

Porous Graphitic Carbon (PGC) particle-packed columns which offer unique physical and chromatographic advantages to silica particle packed columns including pH stability from 1 – 14, polar compound retention under reversed-phase conditions, and temperature stability up to 250 °C.

Certified reference material, Trace CERT ® , 100 μg/mL each component in methanol, ampule of 1 mL.

Introducing Direct Detect™, the first infrared (IR)-based biomolecular quantitation system. Just spot your sample, blank, and read! No sample prep, standard curves, messy cuvettes or liquid waste. With inherent amide bond detection, the Direct Detect™ system distinguishes proteins and peptides from interfering sample components, providing more accurate results without the pitfalls of colorimetric assays. Technology: FTIR Spe…

The Cell Proliferation Kit I (MTT) is a colorimetric assay for the non-radioactive quantification of cellular proliferation, viability, and cytotoxicity.

Sterivex-GP Pressure Sterile Filter Unit.

Steripak-GP filter units are designed for larger scale pressure-driven filtration of tissue culture media with or without serum. They are single use and are not autoclavable. The filter units come in two sizes, with the smaller unit able to filter up to 10 L and the larger up to 20 L. Both sizes utilize the low protein binding, fast flow 0.22 µm EMD Millipore Express membrane.

Steritop bottle top filter units provide a large filter area for rapid sterile filtration of aqueous fluids into narrow-mouth (33 mm) or wide-mouth (45 mm) bottles. A small tab inside the funnel secures an optional prefilter in-place during filtration. For added protection against contamination, the threads for bottle attachment have been slightly recessed in case the funnel accidentally touches a work surface

33 mm diameter sterile syringe filters.

With Millicell inserts, attachment or suspension cells can access media from both their apical and basolateral sides. Cell growth, structure, and function more closely mimic what occurs in vivo. In addition, Millicell inserts make it possible to study both sides of the cell monolayer. Millicell inserts are available for 24-, 12-, or 6-well plates.

Millicell® cell culture insert plates are a patented device designed to support cell growth and differentiation of endothelial and epithelial cell lines, including CaCo-2. The Millicell® device is available with a 0.4 µm PCF and a variety of PET membrane pore sizes. The plate is designed for maximum user convenience and incorporates features such as apical assist for easier pipetting and basolateral access.

MultiScreen® plates with 96- and 384-well capacities, available in a varity of configurations and a diverse set of housing materials, assuring compatibility with varied media formulations and solvents. Solid bottom plates are available for chemiluminescent and fluorescent screening assays, sample preparation and storage, and ELISA including 8-well strip format.
