Automatic Single to 7-Barrel Pipette Puller

PMP-107L: Extra length pull up to 120 mm for the taper and tip. With just pressing one key, an one to 7-barrel pipette can be successfully pulled by the PMP-107 Programmable Multipipette puller. Equipped with a microcomputer, pneumatic pulling arm, pneumatic rotator, optical-digital ruler and a new designed clamp, the PMP-107 can automatically heat, twist and pull a multibarrel pipette. There is no need for any manual rotation or any inconsistent timing interrupt control.

The whole pulling processing is programmable and under control of a preset sequence. The PMP-107 is a new upgrade model from the PMP-100 multipipette puller. Many new features have been added to the PMP-107: The rotation (twist) speed is adjustable. Sequences are easy to copy and modify. Rotation and pulling can act simultaneously while pulling distance is adjustable, which can twist a multipipette with adjustable spirality.

Exclusive Optical-Digital Ruler Measurement

There is an exclusive optical-digital ruler in the PMP-107 to perform precise taper length setting, real-time measurement and tip sensing. With this feature, a user can easily handle taper and tip pulling.

Computerize Real-Time Feedback Heater Control

In the PMP-107, there is an advanced microcontroller to perform real-time heater monitoring and controlling. If a heating level is selected and preset, the microcontroller will measure the actual heating power during heating power on. The measurement will be real-time displayed and feedback to the control unit to match the set point dynamically. As a result, the PMP-107 always provides precise heating power, despite of many times of pipette pulling or thermal/electrical characteristic changing. Under a microcomputer controlling, the heater is smart and reliable.

Programmable and Savable Sequences for Creation and Reproduction

There are 30 user programmable and savable pulling sequences with maximum 18 steps in each sequence. Users can easily program different taper length, tip shape for single to 7-barrel pipettes. Time number, heat level, heat control and action parameters can be individually set in each step. After a special sequence setting up, a multibarrel micropipette will be automatically produced by just pressing the Start button.

Manufacture Preset Programs for 4 and 7-Barrel Micropipette Pulling

Every PMP-107 will be well tested and installed sample pulling programs for 4 and 7-barrel multipipettes. A new user will easily select the right program or just change a few step parameters to fit their special need. The preset programs are convenient and important, not only because they can pull the 4 and 7-barrel pipettes which are supplied by the manufacture, but also as convenient copy templets to make other programs with only minor parameter change for other applications. The PMP-107 has an easy copy program function.

Pneumatic Pulling Force and Compact Size

Comparing with other pipette puller using gravity or magnetic field as pulling force, the PMP-107 applies precise controlled pneumatic pressure as the pulling force, which gives more controllable, even and consistent dragging characteristics. Within a very compact size, the PMP-107 can precisely and automatically perform twisting and multiparameter multi-pulling without inconsistent manual interrupt. A precision micro-linear ball bearing rail and advanced pneumatic components are used to provide no fault pulling movement. A simple 4x4 keypad and full information display LCD let users control easily and read all pulling parameters directly, which include sequences, steps, time, timing, heater level, heater control, tip length and actions. With an intelligent PMP-107, pulling a multipipette is no longer an uncertainty of hand skill, but a reproducible automatic processing.
