Pumps & Instruments

FC_FlowControlPeristalticPump_web_8839v1.jpgFlow 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).

– Flow output signal
–External voltage control of flow rates

Volume flow range 8 µl/min–2400 µl/min Power DC supply or battery (9 V), depending on tube set used.
Dimensions 6 cm W x 6 cm H x 10 cm D


Flow Indicator

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.

Flow rate 0–25 through 0–500 µl/min ranges
Standard ranges 25, 50, 100, 200, 500 µl/min
Accuracy ±3% ±1 µl/min (over 5% to 100% of range maximum)
Precision ±1% or 0.1 µl/min
Panel meter resolution ±0.1 µl/min
Output signal 10 mV/µl/min
Response time < 1 s
Power 117 V/60 Hz or 230 V/50 Hz


Four Channel Superfusion Peristaltic Pump

This quality peristaltic pump is ideal for vessel bath superfusion. The pump includes four flow heads which can be configured in several ways.

For example:
– four inflow lines
– four outflow lines
– two inflow & two outflow lines.

Use INFLOW-IT-44-PKG4 tubing for inflow side; Use OUTFLOW-IT-48-PKG4 tubing for outflow side

Typical Applications +Superfusion of vessel and tissue baths +organ perfusion +General purpose fluid delivery applications
Dimensions 134.9 mm D x 177.8 mm W x 101.6 mm H
Max Flow Rate 75 (ml/min)
Flow Range 0.0075 to 75 (ml/min)

Two Channel Superfusion Peristaltic Pump

This quality peristaltic pump is ideal for vessel bath superfusion. The pump includes two flow heads, one for delivering solution to the bath (inflow), and one for removing fluid from the bath (outflow).

Use INFLOW-IT-44-PKG4 tubing for the inflow side;

and use OUTFLOW-IT-48-PKG4 tubing for the outflow side.

– Easily adjustable speed control
– Start/stop and direction control
– Remote I/O: RJ45 Ethernet, USB, DB-25
– 12 rollers on pump heads minimize flow pulsations
– Click-n-go mini cartridges for easy tubing change
– Uses 3-stop tube sets

WINDKESSEL_in-lineLuerReservoir_web_3437v1.jpgWindkessel 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.
