Laboratory Peristaltic Pump | Longer Pump GF400-1B

Supplier: ProfTek Pty Ltd

The Longer Pump GF400-1B laboratory peristaltic pump provides stable constant-flow delivery, touchscreen and keypad control, and a maximum single-channel flow rate of 2000 mL/min.

stable constant-flow delivery

Controlled liquid handling in laboratory and research workflows.
Touchscreen combined with physical buttons for simple, smooth and reliable operation.
Embedded flow meter closed-loop control algorithm enables stable constant-flow delivery.
Up to 65,000:1 turndown ratio with ±0.1% speed accuracy.
Supports simultaneous multi-source control.
Manufactured by Longer Pump.
