Product Highlights ADVERTISEMENT Transfection Reagent
ScreenFect™ A from Wako is a transfection reagent composed of new cationic lipids. It is applicable to cell lines from various eukary- otic species and can be added directly to media containing antibiotics and sera. It works with DNA and siRNA and can show highly effi cient transfection in common cell lines, stem cells,
blood cells, microglia and primary culture cells. Because of low toxicity, media changes after transfection are not required.

ADVERTISEMENT The First SEC‐MALS detector for UHPLC
The µDAWN™ is the world’s fi rst multi‐angle light scattering (MALS) detector that can be coupled to any UHPLC system to determine absolute molecular weights and sizes of polymers, peptides, and proteins or other biopolymers directly, without resorting to column calibration
or reference standards. Wyatt Technology’s µDAWN connects to the Optilab® UT‐rEX™, the fi rst refractive index detector for UHPLC. µDAWN plus UT‐rEX transfers the benefi ts of SEC‐MALS analysis to UHPLC.

The ULVAC GHD magnetically coupled rotary vane pump eliminates oil leaks and shaft seal wear. A check valve below the inlet port stops oil backfl ow, eliminating messy cleanups and downtime. GHD
pumps off er reduced power consumption, quieter operation and a lower running temperature. These pumps are ideal for analytical instruments and laboratory use due to their high pumping speed and compact size.

www.ulvac.com High Temperature GPC/SEC for Polyolefi ns
Polymer Char off ers GPC-IR®, a reliable 4D Gel Permeation Chromatography (GPC) system dedicated to the characterization of polyolefi ns. It integrates the best infrared (IR)
detectors to measure molar mass distribution and chemical composition simultaneously: the IR5 detector outstands for its high sensitivity and stability, and the IR4 for its capability of measuring carbonyls content. GPC-IR® performs automatically all sample preparation steps including fi lling of vials with preheated solvent and in-line fi ltration.

Kromasil Chiral are chiral stationary phases based on Kromasil unique super-wide pore silica matrix developed at AkzoNobel, and coated with a
functionalized selector to produce Kromasil AmyCoat and Kromasil Cellucoat. These phases have an excellent selectivity for a large number of racemates and come in slurry packed columns with 3 µm and 5 µm particles to enable excellent HPLC and SFC separations. In addition, these phases can also be used for semiprep and preparative applications as they are also manufactured in larger particle sizes. For further information visit
