Fully automatic homogenization and filtration in a single run with the 815 Robotic Filtration Soliprep from Metrohm. This compact and economic automation system makes your daily routine work easier.

The success of analytical methods and the reliability of the results critically depend on proper sample preparation. For example, matrix effects can interfere with chromatographic or photometric determinations. Today the 815 Robotic Filtration Soliprep carries out this tedious work for you – fully automatically and directly after homogenization. Thanks to the Dosino incorporated in your 815 Robotic Filtration Soliprep, the sample solution is fed to the syringe filter at constant pressure. Your Robotic Soliprep works with 100% reproducibility: sample after sample is filtered under exactly the same conditions.

The 815 Robotic Filtration Soliprep is a member of a new sample changer family which is primarily intended for sample preparation of solid samples in ion analysis, e.g. in the fields of ion chromatography, HPLC or voltammetry but, thanks to their flexibility, they can also be used for titrimetric or direct measurement applications without any problems.

The 815 Robotic Filtration Soliprep can reliably master even high sample throughputs. The instruments are extremely robust and have been tested under extreme conditions. To underline the outstanding quality of these sample changers we grant a 3-year warranty.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors.

Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.VoltammetryVoltammetry is a sensitive analytical technique for elemental detection. In a voltammeter the current is measured in the system whilst the voltage is varied. Usually 3 metal electrodes are required including the reference, auxiliary and working electrodes. In polarography, a subclass of voltammetry, the working electrode used is a dropping mercury electrode (DME). The 2 main types of voltammetry are cyclic and linear sweep voltammetry.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.
