Unstirred water baths with double walled, stainless steel (inner) and coated steel sheet (outer) housing. All baths except the 2 litre models feature a drain tap for convenient emptying and are suitable for use with water or alternatively with heat transfer beads. Baths with a capacity of 5 litres or more have a heat transfer bead mode which is activated through the main menu. A drain stopper (plug) is supplied as on optional accessory to ensure heat transfer beads do not get stuck in the drain outlet. Note: Baths are classified Safety Class 1, allowing unattended operation when used with non flammable liquids.

Supor® hydrophilic polyethersulphone (PES) membrane; PP housing. VacuCap® filtration device eliminates the need to constantly refill funnel in traditional bottle top filters as it draws directly from the mixing reservoir. The patented small design accepts a variety of collection vessels and reduces laboratory storage space and waste. The Supor® membrane in the VacuCap® 60 and VacuCap® 90 devices provides high flow rates for fast vacuum filtration of 100 ml to 5 litres of aqueous solutions and is available with prefilter to increase throughput of particulate laden solutions.

Glycerine ≥98%, GPR RECTAPUR®

Supplier: VWR Collection

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:

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.

In general, ion exchangers consist of a cross-linked polymer matrix with a uniform distribution of fixed ionic groups sited throughout the resin structure. These must be balanced by a similar number of ions of the opposite charge, (counter ions) to maintain electrical neutrality. Cation exchangers therefore, exchange and enrich only cations, anion exchangers only anions. In contrast adsorber resins have a non ionic, but depending on the structure, a somewhat polar character, and don't adsorb stoichiometrically both: anions, cations, as well as uncharged compounds.
