ChromSwordAuto® 5: Communicates directly with the HPLC instrument in order to create a fully automated HPLC or UHPLC method development station. The unique ChromSwordAuto® software is capable of developing and optimising HPLC methods fully automatically within just a few hours. Methods already in use can also be optimised, thus reducing analysis time considerably. All you have to do is place the sample in the autosampler, set a few parameters and start the optimisation process. ChromSwordAuto® then predicts the method conditions and controls the HPLC system connected in recording the chromatograms. These are analysed by the software and the optimal conditions determined. The rapid optimisation mode can be used to provide an overview of the performance of the column/solvent system selected or to rapidly screen columns and eluents considered for use. The fine optimisation mode additionally collects and evaluates further ancillary data and produces up to 10 sets of alternative optimal HPLC conditions. Both of these operating modes can be applied in combination with column and solving switching procedures in order to try a variety of column/solvent combinations or to establish optimal pH conditions – fully automatically.

Biotech RC (Regenerated Cellulose) dialysis tubing is crafted from a regeneration process that yields superior temperature tolerances and chemical compatibilities with the same high purity and selectivity as Biotech CE. RC membrane can tolerate concentrated-weak acids & bases, dilute-strong acids and bases, most alcohols and some mild or dilute organic solvents. Exposure to strong polar or organic solvents may damage RC membranes. Use with pH 2 - 12 and temperature 4 - 60 °C.

KrosFlo® hollow fibre membranes for implant technology provide a true-to-life response for drug screening and cancer research. Perfectly suited for implantation, the modified Polyvinylidene Difluoride (mPVDF) hollow fibre membrane is biocompatible, resistant to cell adhesion, hydrophobic and resistant to a wide variety of organic solvents, including most aqueous acids and bases. Furthermore, these hollow fibres can be heat sealed and autoclaved without affecting the molecular weight cut off (500 kDa MWCO) or changing the membrane performance.

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.
