Varian ProStar Model 210 Solvent Delivery Module

Unit powers up and passes internal tests. No further testing has been done by our company.

Manufacturer's Notes:
  • The 210/218 pumps use proven single-piston rapid-refill technology for economy, reliability, and virtually pulse-free operation.
  • A range of interchangeable flow heads allows operation at flow rates from 10 µL/min to 200 mL/min.
  • Biocompatible pump heads are available for those analysts requiring a completely inert flow path.
  • A single-channel 22 bit analog-to-digital converter built in to each 210/218 pump can convert a detector signal to digital form and transmit the data to a computer system.
  • Five programmable analog inputs and three programmable relay outputs are available to further automate the HPLC system.
  • The 210/218 is easy to use and very flexible in operation. It can be used in several different modes of operation: as a standalone isocratic pump, as either a master pump or a slave pump in a completely automated HPLC system, as a sample inject pump in a preparative system, or in a fully-automated HPLC system controlled by an external computer. In each case, the provides outstanding accuracy over its entire range of pressures, flow rates, and solvents. The 210/218 operates very quietly because of minimal motor noise and resonance vibrations.
Harvard Apparatus Digital Dual Syringe Pump Model '22' Cat# 55-2222
Harvard Apparatus Digital Dual Syringe Pump Model '22' Cat#55-2222
Our Price: $300.00

Harvard Apparatus Digital Dual Syringe Pump Model '22' Cat# 55-2222.

Powers up and works. Power cord is included.

The Model is an Infusion Only syringe pump employing a microprocessor controlled small step angle stepping motor driving a lead screw and half nut. A key pad is used for data entry of flow rate and syringe diameter. The microprocessor calculates the cross sectional area of the syringe to be used and calibrates the flow rate for that syringe. A number of special features result from use of microprocessor technology.

If the user selects a combination of syringe size and flow rate that is outside the range of the pump,(eg, 50 ml/min with a 10 microliter syringe) the pump will reject this instruction and notify the user.

The pump remembers its last instructions, entered from the keyboard, including diameter and flow rate even after the power has been disconnected.

An optical sensor detects lack of motion due to jamming, end of syringe travel, kinking of tubing, etc.shuts down the pump and alerts the user.

The pump will stop and alert the user during a loss of power.

Vacuum Pump is operational and the Vacuum Controller powers on. No further testing has been done by our company.

This sale comes with one vacuum pump and one vacuum controller. The controller allows for a set point to be made and will switch off the pump once the selected target has been reached. If a second vacuum controller is added to the system then it becomes possible to simultaneously run two different and independent process with just one pump.
