D-21FT 50-2R Fixed-Flow Timed Peristaltic Pump — 6 Flow Rates, 12V Battery

Laboratory peristaltic pump with fixed flow and integrated cyclic timer. Six flow rates available depending on the tubing fitted. Designed for repeated, automated dispensing of variable volumes — from small doses to continuous large-volume transfers.

Key Features

• Flow rates: 13 / 55 / 220 / 330 / 435 / 750 ml/min
• Pump head: Polycarbonate rotor with two rollers
• Cyclic timer: Programmable from 0.01 s to 99.99 h (independent stop and run times)
• Battery: Rechargeable 12V — mains-free operation
• Remote control: Footswitch socket included (footswitch not included)
• Power supply: 230V 50/60 Hz
• Dimensions: 240 x 260 x 90 mm (W x D x H)
• Weight: 2.0 kg

Typical Applications

Automated dispensing on filling lines, reagent transfer, cell culture dosing, and any application requiring timed repeatability. The 12V battery extends usefulness to benches without convenient mains access and field work.

Routinely used in microbiology, biochemistry, quality control and industrial process laboratories.

Installation and Maintenance

Tubing is removed from the head without tools — fast changeover between fluids or for sterilisation. Dispensed volume varies with the internal diameter of the tubing fitted, allowing flow adjustment without any modification to the electronics. Supplied with tubing and footswitch socket.
