Pumps offer lowest pulsation, highest
accuracy
Dispensing sensitive, delicate media in pharmaceutical, environmental, biotech or other OEM applications demands a pump with high accuracy, low pulsation, zero contamination and high repeatability
Dispensing sensitive, delicate or difficult media in pharmaceutical, environmental, biotechnology or other critical OEM applications demands a pump which provides high accuracy, low pulsation, zero contamination and high repeatability across a number of channels Ismatec meet this demand with a range of multi channel tubing pumps which offer a choice of 4,8,12 or 24 channels, delivering flows from as little as 0.002ml up to 44 ml/min per channel

Michael Smith Engineers has announced that Hydra-Cell pumps are a cost-effective alternative to traditional metering pumps.
Small pump package delivers big performance
The Micropump innovative I-Drive electromagnetic drive has been developed to meet the increasing demands from OEM engineers and machine builders who require high performance from less space
Typical applications include perfusion of animal tissue slices, sampling from tablet dissolution systems and flow injection analysers.
Another recent example was for use in the study and simulation of the environmental influences of rain water in free-land plants.
Available from Michael Smith Engineers, these pumps use a planetary drive via a sun wheel providing direct drive to eight stainless steel rollers.
This prevents axial push-pull friction on the tubing and results in increased service life of the tubing, lower pulsation and very high repeatability on all channels.
The pumps are easy to use with features such as the Ismatec click 'n' go cassettes with automatic pressure setting and two stop tubing.
Models and drive options include the IPC and IP, capable of 0.4 to 45 rpm giving a flow range of 0.002 to 44 ml/min per channel, or the IPC-N (and IP-N) capable of 0.11 to 11.25 rpm, providing a flow rate of 0.0004 to 11 ml/min (dependant on which of the 10 tubing sizes available is used).
All drive options have a speed range of 1 to 100% and have a resolution of 0.1%.
Both IPC and IPC-N models include a microprocessor which enables control by PC or via analogue signals, while an easy-to-use membrane keypad with LED display allows users to programme the pump to perform a range of functions, such as dispensing set volumes, set dispense times and pause time between dispenses etc.
Ismatec pumps, which are housed in robust, laquered stainless steel IP30 casings, are suitable for continuous operation and can be dry-run without any problem.
