Peristaltic Pumps
NOTE: PP2T102-TY tubing is recommended for FIAlab 2500, when running serial
assays (nitrate, phosphate, ammonia, etc)
The advantage of peristaltic pumps is their multichannel functionality, that allows liquids to be propelled continuously and independently at selected flow rates. Peri pumps are ideal for laboratory operations, where a frequent supervision of the apparatus is practical. While the flow rates of Pp change as the pump tubes get stretched, this drawback can be offset by timely calibration of the instrument. We have chosen the most reliable pumps available on the market to construct FIAlab systems.
Watson Marlow pumps, with internal controller show Swedish quality. All pumps can be manually operated as well as computer controlled via TTL and DAC signals. Near instant start/stop/reverse operation makes these pumps fully FIA compatible. These instruments are work horses on which laboratory based assays, and many other fluidic handling operations rely. We offer a wide selection of peristaltic pumps, from panel mounted to stand alone or computer controllable. Below are some of our more popular models.
All of the following pumps include manual (push button) controls for direction and speed, as well as remote controlvia TTL signals (for direction and on/off) and analog input signal (0-5 VDC or 4-20mA) for speed. The LJU12 Control Module can be utilized to interface any of these pumps to a computer's serial port.
C-Series- 4, 6 , 8 Channel Laboratory Pump
The C-Series laboratory pump is designed to combine quality, technology, accuracy at low flow rate, and versatility. Each tube has its own pressure plate - tube cassette, which is detachable even during operation. The cassette has individually adjustable pressure springs, making it possible to use widely different tube diameters simultaneously. The rotor houses eight rollers of acid-proof stainless steel, each with double ball-bearings to give low pulsation, low friction and no static charging.
Specifications:
Channels: 4, 6, 8 Rollers: 8 Voltage: 110VAC/230VAC (please specify) Direction: CW / CCW Dimensions (L x H x W): 105x105x185 mm Weight: 2.1 kg Flow rate 0.0005 - 50 ml/min/channel (function of RPM and tube diameter) Pressure 25 psi
VS-Series - 2, 3, 4 Channel Precision Laboratory Pump
The VS-series laboratory pump is designed for a highly precise and almost pulseless flow. The pump uses ten rollers and other design features to provide an extremely smooth flow, making this pump ideal for FIA applications.
Specifications:
Channels: 2, 3, 4 Rollers: 10 Voltage: 110VAC/230VAC (please specify) Dimensions: (L x H x W): 105x105x185 mm Weight: 2.1 kg Flow rate 0.0005 - 17.5 ml/min/channel (function of RPM and tube diameter) Pressure 15 psi
U-Series – 1 Channel – Low to High Flow Rates
The U-series laboratory pump is primarily designed for high flow rate applications. The pump is easy to use, and can handle flow rates ranging from 0.07 ml/min to 150 ml/min, and pressures up to 65 psi.
Specifications:
Channels: 1 Roller: 4 rollers for U1
Voltage: 110VAC/230VAC (please specify)
Direction: CW / CCW Dimensions L x H x W): 105x105x185 mm Weight: 2.1 kg Flowrate 0.07 - 150 ml/min/channel (function of RPM and tube diameter) Pressure 65 psi
The S2 Laboratory Mini pump
This pump is designed for small spaces and small budgets. This pump is ideal for filling sample loops, where high flow rate precision is not required.
Specifications:
Channels: 2 Rollers: 4 Voltage: 18 VDC (power supply for 100-240 VAC included) Direction: CW / CCW Dimensions: (LxHxW): 133x84x80 mm Weight: 1.0 kg Flow rate 0.1 - 35 ml/min/channel (function of RPM and tube diameter) Pressure 25 psi
Each S-Series pump order includes one custom cable for controlling the pump's start, stop and reverse functions directly from the serial port of a PC compatible computer. Windows based software included.
