3 channel
15 Rollers
Flow rate/channel: 0,00015-50 ml/min
Max Pressure: 2 BAR

Three-channel pump fitted with 15-roller acid proof Stainless Steel rollers with ball bearings for accurate flow control and low pulsation, obtaining flows down to 0,001 ml/min.

The QP-3 LAB ASC is a 3-channel peristaltic pump fitted with 15 stainless steel, ball-bearing rollers which allows for consistent and low pulsations. It also helps achieving more even flow. The acid-proof, stainless steel rollers creates high mechanical tolerances and low friction and no static electricity, handles applications when high accuracy is needed. The pump has a low flow rate, starting at at 0,001 ml/min (0,003 ml/rev).

Created For Lab Environments

The included Accurate Speed Control casing is powder coated, ensures high durability and long lifespan. The control board and buttons are optimized for the QP-3 pump and allows for FWD, RWD, Stop, and speed-control functionality. The control board is based on PWM (Pulse-Wide Modulation) with our unique Switch Technology, which achieves up to 90% efficiency. This prevents overheating, removing the need for heat sinks, and allowing you to maintain a stable and exact speed (+/-3%). On the back of the pump is a 9-pin D-sub connector for external start FWD, REV via potentialfree contacts and externel speed control via 4-20mA signal (on request 0-20mA).

Remote cables and/or foot pedals on request.

Voltage in: 24VDC, 100-240VAC power supply included in the product.

Optimized Pressure and flow
The QP-3 LAB ASC pump head has Oina’s unique dual spring loaded adjustable occlusion which optimizes pressure and increases tube lifetime. The unique design not only allows for low power consumption but also less pulsation and more even pressure control.

Easy Tube Loading
The easy tube loading mechanism ensures easy tube loading and replacement.
