Pumps & Instruments
Flow Control Peristaltic Pump
This miniature peristaltic pump delivers precise volume flow rates over a range determined by the setting of two calibrated potentiometer controls, and the tube set size chosen. It is similar to the pump used in the pressure servo control unit (PS-200).
Features:
- Flow output signal
- External voltage control of flow rates

Flow Control Peristaltic Pump
The FI-1 provides a digital readout of the flow rate delivered by the FC flow control pump or the PS-200 pressure servo control pump. Flow rate can be monitored directly on the front-panel meter in µl/min, or using the analog voltage output signal, which is compatible with most data acquisition systems. The FI-1 also has a connector that enables remote control of flow rate using a D/A output or other analog voltage source.

Windkessel Reservoir, In-Line Luer , pair
A windkessel is a plumbing component that serves to dampen pressure/flow pulsations. Pulsation dampening is accomplished by introducing a compressible air reservoir into a physiological solution flow circuit. Our windkessels are constructed using a Luer tee fitting that can be connected in-line with your vessel perfusion circuit. The top arm of the Luer tee has the air-filled reservoir that serves to dampen flow/pressure pulsations of the fluid going through the main line of the tee. Windkessels can be introduced on the downstream side of a FC Flow Control Pump, as well as on the upstream side of a PS-200 Pressure Servo Pump in constant pressure/constant flow systems. Includes two windkessels.
