Optos Model 1HI Piston Metering Pump, PEEK, 1/4" Piston Dia, 0.01 to 20 mL/min

Compact pumps provide precise flow rate control and smooth fluid delivery at high pressures
  • Reciprocating piston design for precise flow control
  • High-resolution stepper motor minimizes pulsation
  • Control flow remotely via analog or RS-232 connection
  • Integrated piston wash extends piston seal life
  • Solvent-resistant membrane keypad
  • Use with liquids with temperatures ranging from 5 to 260°C (41 to 500°F)
  • Compact meter only measures 10 cm W x 24 cm D (4" x 9.5"), saving valuable benchtop space
  • PEEK liquid end cylinder
  • 1/8" stroke length
  • 1/4" piston diameter
  • Flow rate range from 0.01 to 20 mL/min
  • Manufacturer defect warranty
The Optos series metering pumps deliver high precision and reliability at high pressures. Achieve flow rates from 0.002 to 20 mL/min with ±0.3% reproducibility with Model 1 meters. The reciprocating piston offers precise flow control while an advanced software algorithms control high-resolution stepper motor to maximize flow output and minimize pulsation. Easily set flow rates using the up and down buttons on the solvent-resistant keypad. Remotely control your meter via an analog signal (4 to 20 mA or 0 to 5 VDC) or RS-232. Contact closures allow remote start and stop, flow output (0 to 5 VDC), and pump error output.

Select a pump that uses the upper half of the flow range listed for each pump. Piston cylinder comes available in two materials€”316 stainless steel (SS) and PEEK. 316 SS offers excellent chemical and corrosion resistance; use PEEK for extremely corrosive fluids. A fully integrated piston wash system cleans out buffers or solutions which can crystallize and lead to abrasion of the piston seal, shortening the piston seal life.
Includes: Inlet and outlet fittings, 60 cm (23.5") L tubing, and 110/115 VAC power cord.
