An Asia flow chemistry system from Syrris is helping to streamline biocatalysis reactions for researchers at the Biocatalysis and Organic Synthesis Group at the Chemistry Institute of the Federal University of Rio de Janeiro. Professor Rodrigo de Souza explained: "Our main aim is to take existing batch processes and optimize them under continuous flow conditions. For example, we have been able to transfer a cascade reaction - involving chemical catalysis followed by biocatalysis and a final chemical catalysis - from batch to continuous flow, eliminating the laborious task of isolating each intermediate. This dramatically reduced the reaction time without compromising selectivity and is more efficient, giving us a greater yield. Using continuous flow processes also avoids causing mechanical damage to the biocatalyst, so it can be recycled many more times than with batch reactions."


"We have been using the Asia system for several years, and it helped us to become the first group at the University - and in Brazil - to develop biocatalyzed continuous flow reactions.
It is a very user-friendly system, and the wide range of flow rates offered by the Asia Syringe Pump and the platforms modular design provide us with the flexibility we need. For example, we have the freedom to incorporate a FLLEX (Flow Liquid Liquid EXtraction) unit if we need to purify a product by liquid-liquid extraction. Asia is the ideal solution for our research."

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
