Universal System for Catalyst Synthesis
SOPHAS-Cat has been specially designed for Catalyst synthesis. The synthesiser is based on an X, Y, Z pipetting station. All functions required for synthesis; heating, cooling, mixing, vacuum filtration, powder dispensing and liquid handling are integrated into the platform. The system has 3 vortexing reaction stations, 2 with software controlled heating from ambient to 150°C, one with cooling to -40°C or optional -80°C.
For the reactor stations, various reactor blocks with the footprint of a microtitre plate are provided. As standard, blocks with 96 (1.2ml or 2ml), 24 (7-10ml) or 8 (20-40ml) glass or PTFE reactors are available. Borosilicate glass, quartz or PTFE reactor plates can be used and special reactor blocks e.g. ceramic reactors, are available on request.
The integrated robotic arm transports the reactor blocks to the various reactor stations and positions for heating or cooling, pipetting and parking on the instrument. The arm also operates the vacuum filtration station, it can open and close the vacuum block, insert the receiving rack and exchange the filtration (SPE) block or cartridge rack. The robotic arm can also pick up additional tools such as a powder dispenser, temperature probe, pH electrode or overhead stirrer. A reflux unit which uses gas cooling can be provided as an option.
Solvents and reagents are distributed by the four independently operated 2 or 3 channel probes. Each probe is connected to 2 precision syringe pumps. As the needles provide variable spacing from 8 to 38mm, SOPHAS Cat can handle any format of reactor block and racks. Two liquids can be delivered at the same time through parallel channels while the third channel can provide vacuum or gas (nitogen, argon etc).
The powder dispensing tool REDI, automatically distributes fixed or variable amounts of dry powders into the reactors. The fixed volume REDI tool comes with a set of 5 calibrated tips, however options are available for a manually adjustable tip or software controlled variable volume tip (REDI VARIX®).
Inert gas control can be provided for reactors and reagents. Inert gas can automatically be added if reagent is aspirated or delivered to a reactor or reservoir. Special chemically inert septa for reactors and reagent bottles have been developed.
WinSOPHAS Windows software, controls all functions of SOPHAS-Cat. The software offers maximum flexibility for any synthesis strategy or chemistry. Network communication and exchange of data via Excel or ASCII files allows easy integration into existing systems and complete documentation of the experiments.
