The assistant includes a variable single wavelength UV detector, an automatic injection valve and a buffer pump. A leak sensor and the capillary guidance as well as the optional mobile control with touch screen facilitate the safe and user friendly operation. Modern design with completely demountable fronts and exchangeable colored side panels turn the system into a v...

Detection via the integrated UV-Detector. The sample can be automatically injected via the integrated valve. A leak sensor and the capillary guidance as well as the optional control unit with touch screen facilitate the safe and user friendly operation. Modern design with completely demountable fronts and exchangeable colored side panels turn the system into a visua...

Two exchangeable pump heads allow a wide range of flow rates with one pump. Practically pulse-free flow is achieved by our enhanced smart drive control which actively prevents pressure ripple instead of just dampening it. The improved design also ensures a low dead volume. The BlueShadow pump 40P is available in two different versions, either the pump only or fully deve...

It is strongly recommended for the use of aqueous eluents, also in combination with organic solvents like methanol or acetonitrile. The chemical modification of this gel permits its use with a variety of organic mobile phases. The universal application of PSS SUPREMA gel to wide range of polymer types is obtained using a well-balanced ratio of hydrophilic and hydrophobic...

You can choose between an aqueous buffer version and a solvent resistant version. Additionally, the plunger is available in two different lengths. They can be easily be packed and refilled with any resin for your purifications of proteins. The columns are supplied with all necessary accessories.

pressure and pH-stable, macroporous styrenedivinylbenzene copolymer network for organic GPC.

10 to 30 bar, depending on column diameter). You can choose between an aqueous buffer version and a solvent resistant version. Additionally the plunger is available in two different lengths in order to easily adapt to different bed lengths. The ECO glass columns can be equipped with an optional water-jacket to make them part of our Benchtop Cooling option and can be used...

Now we introduce Eurospher II, our new workhorse for an even wider range of application areas in classical HPLC, fast HPLC Plus and ultra-fast UHPLC. Based on an ultra pure spherical silica gel, Eurospher II is a high performance column material for analytical, semipreparative and process-scale applications. Eurospher II features very narrow particle and pore size distri...

Strict manufacturing procedures ensure a very narrow pore size distribution. Interfering anions or heavy metal ions on the silica surface are not present in Eurosil Bioselect columns because only ultra pure silica gel and high quality chemical modifications are employed.
