New - Levels of Versatility Configurations: push-pull, standard, remote, high pressure, multi racks Connectivity: rs232 and USB for PC; RS 485 for daisy chain   Click Here for More Details Harvard Apparatus Pump 11 Plus Syringe Pumps The Pump 11 Plus family of pumps are our most basic pumps, but provide the precision and flow that Harvard Apparatus pumps are known for. Select from either 1 or 2 syringe models and from basic infusion only or the more advanced infuse/withdraw models. The infuse/withdraw models also have RS-232 communictions.    Harvard Apparatus PHD 22/2000 Syringe Pumps The Harvard PHD 22/2000 Advance Syringe Pump family is the most versatile of the pump lines. This pump is available for infusion only or infuse/withdraw models. This is the only pump that is also available in a Push/Pull configuration. All pumps have RS-232 communications capabilities, but there are also PHD 22/2000 pumps that are programmable directly from the keypad. In addition, a multitude of syringe racks are available to hold 2, 4 or up to 10 syringes. A microliter syringe rack is also available for microliter applications. Remote versions are also available where the control box and pumping mechanism are separated by a 9.1 meter (30 foot) cable.    Standard Infuse/Withdraw Harvard 33 Twin Syringe Pump The Pump 33 Twin Syringe Pump is the only pump in the Harvard Apparatus had line that has 2 independent motors. It is like having 2 pumps in one chassis. Both motors can infuse, withdraw or infuse and withdraw simultaneously. With the addition of an optional valve (as shown in this picture) this pump can infusion continuously 24 hours a day, 7 days a week, 365 days a year.    MRI Compatible Syringe Pump NEW Remote Operated MRI Compatible Syringe Pump meets the needs of the MRI environment. • Ideal for drug delivery and tracer studies, MRI imaging. The MRI Syringe Pump from Harvard Apparatus combines a two syringe pump mechanism, constructed of nonferromagnetic metal, with a 30 foot cable connection to the pump electronics control box. (60 ft cable available). A Run/Stop switch on the remote actuator allows control of the pump when standing next to the MRI. High Pressure OEM Syringe Pump Modules The High Pressure Syringe Pump Module employs a microcontroller which controls a small step angle stepping motor that drives a lead screw and Pusher Block. Microstepping techniques are employed to further reduce the step angle, eliminating flow pulsation. Data can be entered via an RS-232 connector located on the micro controller. The microcontroller calculates the cross-sectional area of the syringe selected and calibrates the flow rate and volume accumulation. The numerous features of the High Pressure Pump Module result from the use of microprocessor technology. Micro-Liter OEM Syringe Pump Modules The new “µl” Pump Module is a low cost, highly precise, single syringe infuse/withdraw pump capable of low to moderate back pressures. It is available in one version only and will hold one syringe of any make from 0.5 µl to 1 ml. The diameter of the syringe and desired flow rate are entered via the RS-232 serial port, and the internal microprocessor drives a precision stepper motor to produce accurate fluid flow. This unit is designed to operate inside an enclosure, cabinet, or on top of a bench. The board may be removed for “remote” operation. Milliliter OEM Syringe Pump Modules The new “ml” Pump Module is designed as a low cost, highly precise, single syringe infusion pump capable of low to moderate back pressures. There is only one version of the “ml” Pump Module available at this time. A dual “ml” Pump Module version can be produced upon customer request. Typically, the “ml” Modular Pumping Component holds one syringe of any make, from 0.5µl to 60ml. The diameter of the syringe and desired flow rate are entered via your PC, and the internal microprocessor drives a precision stepper motor to produce accurate fluid flow. This unit is designed to operate inside an enclosure, cabinet, or on top of a bench. The board ay be removed for “remote” operation.
