Patented Pumping Technology Expands Flow Chemistry Range
The Asia Syringe Pump from Syrris, designed specifically for flow chemistry, employs patented pumping technology, giving chemists a tool to perform flow reactions not possible using HPLC pumps or ‘single shot’ syringe pumps. Used in combination with the Asia Pressurized Input Store, the Asia Syringe Pump takes advantage of positive input pressure to deliver continuous, extremely smooth flow – from 1 µl/min to 10 ml/min – at pressures of between 0 to 20 bar, minimising outgassing and cavitation.
The Asia Syringe Pump can be used independently, or as a component of the award-winning modular Asia Flow Chemistry system. Control of flow rates and reaction timings is better than ever before, ensuring accurate control of residence time in the flow reactor, as well as reducing the number of by-products generated during a reaction. Its ultra smooth, chemically resistant, continuous flow channels are ideal for moisture and air-sensitive reagents, and can accommodate a wide range of solvent and solution viscosities and volatilities, including dichloromethane and ether.

Vici’s Microvolume Diaphragm Valve is designed for trouble-free use in applications requiring minimal maintenance and maximum lifetime, making it the ideal choice for the process industry, automated lab analysers, and continuous- monitoring environmental analyses. Three configurations are available: a 4 port internal loop sample injector; a 6 port external loop
sampling/switching valve; and the industry’s first 10 port multifunctional diaphragm valve.
Lifetime for the DV22 can exceed 1,000,000 cycles at ambient temperature/300 psi or 500,000 cycles at 175°C/300 psi. The standard valve is for applications in which the sample is above ambient pressure, but it can also be used with sub-ambient pressures, such as when the sample is pulled through the valve by vacuum.
Actuator air (40-50 psi) is supplied to a side port with 10-32 female threads, permitting use of a variety of compression or barbed fittings. A 3-way solenoid is required for actuation, which may be ordered separately.
Maintenance procedures are greatly simplified, since the valve is held together by a single screw and locating pins insure proper alignment.

Innovative Peristaltic Pump Provides Three Independent Channels from a Single Pump A new design of peristaltic pump which
allows independent flow control of three separate channels within a single pump has been introduced by Idex Health & Science. Available in the UK from Michael Smith Engineers the Ismatec®
Reglo ICC
(independent Channel Control) peristaltic pump expands the power of laboratory and life-science pumping by providing individual control of each fluidic channel and so eliminates the need for multiple pumps.
Maximising available bench-top space is important for many laboratories and the
Reglo ICC pump helps to minimise the clutter of multiple pumps as well as allowing users to solve application complexity in a single pump.
The key features and benefits include, continuous pumping or precision dispensing, in one, two, or three channels, the flexibility of bi-directional flow in each channel and easy-to-use tubing cassettes for quick, convenient changeovers. Most importantly, independent channel calibration minimises the tube-to-tube differences and this results in optimum accuracy for a multi-channel peristaltic pump.
The New Miniature Gas Pump 1010
The Reglo ICC pump, which is self-priming and is not sensitive to dry-running, can handle flow rates from of 0.002 up to 35 ml/min and differential pressures up to 1 bar, while an easy-to-use USB interface means connections can be made quickly.
