Micro-Perfusion Pump

Computer Control Interface for Pumps

The Problem:

When imaging cells in a rigid structure such as a chamber having a coverslip as an observation surface, one must appreciate the fact that any rapid changes in flow rate will translate to microdynamic changes in pressure within the optical cavity of the chamber. This causes the coverslip to behave like a diaphragm thus flexing out of focus due to the narrow depth of field of the microscope objective. To eliminate this problem at the lower flow rates and significantly reduce it at higher flow rates, Bioptechs recommends the Micro-Perfusion pump for use with all its micro-observation systems.

The Solution:

The Micro-Perfusion Pump is a miniature, single or dual, channel, full-featured peristaltic pump designed specifically for low-flow rates. Unlike most peristaltic pumps that are driven by stepper motors, the Micro-Perfusion pump is driven by a tachometer regulated, multi-stage DC gear motor. This assures a smooth analog rotation of the roller spindle, free of instantaneous steps. It is regulated by either the internal control circuitry adjustable from 0.2-550 ml/hr (dependant on pump) or it can be interfaced with a computer through a USB D/A port. Bioptechs provides a kit for this purpose that includes all cabling, software, and hardware needed for a dual pump setup. The pump comes with an external 9 volt AC adapter and also contains an internal 9 volt battery which can function as the primary power supply if needed.

Multiple tubing sizes are available, from 0.015 to 0.062, while 0.062" is generally best suited for most imaging applications. The pump tubes are available in silicone rubber and C-Flex. They are terminated with a 1/16" tubing barb. The base of the pump is threaded for easy mounting to a stand or fixture near the microscope. An optional rod mounting clamp is available for mounting to a 1/2" rod.
