The VWR® Constant climate chambers with Peltier technology feature excellent variation and fluctuation values for temperature and humidity. They are energy efficient and environmentally friendly, with a low noise level, and they work almost vibration-free as no compressor is installed. These models, with forced air convection, provide a temperature range between 0 to +70 °C (max. 20 °C below ambient) and feature a stainless steel (DIN 1.4301) inner chamber and stainless steel housing, solid outer door and internal glass door. The PREMIUM models have an intuitive menu and user friendly software and a USB port with flash drive for data download to USB stick and for uploading programs. They can be connected to an Ethernet or Wi-Fi network for remote control from any computer, and users can receive notifications about selectable parameters via e-mail.

The XT family of VWR® PCR thermal cyclers combine industry- and customer-inspired innovation housed in a robust, low noise design that fits on virtually any bench top. The fast ramping 96-well block is accurately controlled by eight Peltier elements ensuring reproducible PCR results and offering a gradient PCR option. Making use of advanced technology, XT cyclers can be connected via Ethernet and controlled remotely by a primary XT⁹⁶ cycler, a PC or a mobile device (smartphone/tablet). The software/App needed comes free and provides the same intuitive user interface as the touch-sensitive, sharp 7" TFT display that the XT⁹⁶ cycler is equipped with. When used as part of a remote control configuration, the XTender⁹⁶ makes a perfect secondary unit, having no built-in display, but reduced to its core function of providing excellent PCR results, while saving costs and valuable resources. Other innovative features:

NHS-activated Sepharose™ 4 Fast Flow is composed of cross-linked 4% agarose beads, NHS activated for coupling amino-containing proteins and peptides in process-scale applications. NHS (N-hydroxysuccinimide) coupling forms a chemically stable amide bond with ligands containing primary amino groups. The resin provides a spacer arm to the coupled ligand and suitable for immobilising smaller protein and peptide ligands.

The VP 220 is ideal for rotary evaporators providing the powerful vacuum needed for demanding evaporations without the use of oil pumps. VP 220 has built-in Advanced Vapour Management (AVM) which means precise control capability for the distillation of organic solvents and applications handling aggressive vapours and gases. The VP 220 is especially effective for rotary evaporation of low boiling point solvents such as acetone and ethanol and is able to rapidly strip DMF at 35 °C. The pump parts are all made of corrosion resistant materials such as PTFE and Kalrez to handle aggressive vapours, and together with vacuum adjustment, the evaporation process will be optimised. Use the vacuum adjustment to increase the vacuum until bubbles form in the evaporation flask - then lower it slightly. Reduce the vacuum for fast reaction to bumping or foaming.

Purospher® RP-18 is designed for the separation of problematic basic compounds with simple neutral eluents. In addition Purospher® RP-18 allows the separation of hydrophilic compounds with aqueous mobile phase. Purospher® RP-18 is based upon a high purity, metal-free silica. The multi-step chemical modification and deactivation of the surface, and the polar endcapping, enables a peak-tailing-free elution of basic and chelating compounds. Purospher® RP-18 is not suitable for the separation of acidic compounds. The good chemical stability of Purospher® RP-18 enables the use of mobile phase conditions at pH 8 for a long period of time.
