Low pulsation/high accuracy
multi-channel pumps
Range of multi channel tubing pumps deliver flows from 0.002ml to 44ml/min per channel, using a planetary drive via a sun wheel to prevent axial push-pull friction on the tubing
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 Michael Smith Engineers says Ismatec meets 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 44ml/min per channel

Precise smooth flow from micro annular gear pumps
Ultra-compact HNP pumps deliver liquids with a precision of CV<1% across flow rates from 0.25microlitres to 1152ml/min for OEM, analytical, biotechnology and other similar applications
Typical applications include perfusion of animal tissue slices, sampling from tablet dissolution systems and flow injection analysers.
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 described as easy to use with features such as Ismatec's click'n'go cassettes with automatic pressure setting and two stop tubing.
Models and drive options include the IPC and IP, capable of 0.4-45rpm giving a flow range of 0.002-44ml/min per channel or the IPC-N (and IP-N) capable of 0.11-11.25 rpm, providing a flow rate of 0.0004-11ml/min (depending on which of the ten tubing sizes available is used).
All drive options have a speed range of 1-100% 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.
