9QX Series
The 9QX is the smallest flip-top peristaltic pump available. With an elegant body design of just 40 x 62 mm (width x height) it stands just 21.5mm (depth) off a panel mount. The flip-top design allows tube loading and unloading with ultimate ease.
This series is the 3rd generation of the highly successful 9K miniature peristaltic pump from Boxer and is designed for accurate dispensing of liquids.
DC / Gear motor versions offer a range of 33 to 520 rpm with optional shaft encoder providing accurate feedback of rotor speed.
Stepper motors versions offer the versatility of finite speed / flow control with supporting drivers and optional rotor encoder.
› Flow rates from 10 μl to 200 ml/min
› Flip-top design for continuous tube
› Floating saddle for tube life > 2000 hours
› Repeatability to 1% over tube life
› 5 different tube sizes
› 3 , 4 or 6 roller configuration
› Encoder options for feedback of rpm (for DC and Stepper motor versions)
Tubing must always be ordered separately.
Flow control of the DC / Gear motor versions is available in combination with PWM Flow Controller.
