The invention relates to a chromatographic process for substance separation in the context of the preparation of chemicals such as, for example, chiral pharmaceuticals, isomers or biomolecules on the small-scale and production scale, based on Simulated Moving Bed (SMB=countercurrent chromatography) technology.

Modular valve system for countercurrent chromatography process

Method for the production of chemical and pharmaceutical products with integrated multicolumn chromatography

Static mixer module, consisting of a disc which is provided with a multiplicity of orifices () and is structured on its front side and on its rear side by means of channels (), and in which the orifices () are made in the flanks () of the inlet channels () and open into the flanks () of the mixing channels (). Furthermore, a mixer arrangement is described, which consists of at least two static mixer elements arranged one behind the other, at least one mixer element being a disc-shaped static mixer module. The mixer module and the mixer arrangement are used in pipelines and housings through which a flow passes.

Static mixer module

A combination static mixer and heat exchanger having heat exchanger tubes () which are provided over their circumference with fins () which have a static mixing effect.

Mixer/heat exchanger

Modular device and method for carrying out experiments in parallel on process substances to develop technical methods, comprising at least a multiplicity of individual reactors which are controllable independently of one another said reactors being comprised of pressure-tight chambers having separable sample vessels, and optionally, stirring devices, heating instruments, cooling instruments, or both, a monitoring unit for monitoring or controlling at least the pressure and the temperature in the individual reactors, pressure-tight lids having independent feed lines and optionally independent discharge lines for individual process substances; a plurality of the lids being simultaneously sealable upon the rectors by a common sealing means ().

Device and method for carrying out experiments in parallel

This invention relates to an apparatus and a process for rapidly and accurately dispensing fluids, in which at least one component is dispensed into the reaction vessel in two or three stages. In this process, the amount of fluid dispensed in the second and third stages is determined on the basis of the mass flow rate calculated in the preceding sub-step.

Process and apparatus for dispensing fluids

A modular, actuated valve controlled by means of pressure fluids comprising a head plate mounted on a housing plate mounted on a base plate, held together by screws, having a piston with attached valve spindle and a pressure relief space provided between the flow passageand the piston.

Modular, pneumatically operated control valve

Rapid and efficient production and examination of formulations for polyurethane foams using only small amounts of materials are achieved by allowing the foam-forming mixture to foam in a container, preparing disks from sections of the container in which the foam is present and removing a plurality of cylindrical samples having substantially the same density from the disk.

Screening process for the production and characterization of polyurethane foam materials

Two-component polyurethane coating composition with anti-corrosive properties

A metering apparatus includes a roller charging device having an encircling groove which allows an accurate metering in minimum quantities, using the respective angle of slope of a pourable loose material.
