Accurate dosing is particularly important in the pharmaceutical, cosmetic or food sector.
Comprehensible process conditions are a prerequisite for the safe conveyance of sensitive media. This is ensured by a control accuracy of ±1% and precise speed adjustment (5 — 120rpm). In addition, an optional foot switch allows the pump to be operated in closed exhaust hoods. The parameters - speed, direction of rotation and on/off function - can be controlled externally either through the analog or digital interface. In this model, you can choose between a single-channel or multichannel pump head. Flow rates vary depending on the pump head: the single-channel head has a flow rate of 0.38 — 813 ml/min; for the multi-channel head 0.005 — 364 ml/min. Depending on the focus of the process, the following parameters can be set on the device: Speed, tubing diameter, flow rate display, metering volume, interval dosing and break times. The pump can be calibrated for optimum dosing results.
Other technical Data:
• Speed setting: digital
• Electronic speed control: digital
• Select direction of rotation: CW / CCW
• Analog interface: for speed 0 - 10 V / 4 - 20 mA direction of rotation start/stop
• Safety feature: electronic current limiter and overheat protection
• Multi-Channel Operation
Increase your throughput by running up to 12 individual cassettes on one single pump drive and pump head system.
Separate metering into multiple vessels with different feed rates in a single operation by using different tubing dimensions to adjust flow rate.
Save time: tubing change is done in just seconds.
In addition to standard pump heads which feature a 4-roller system you can choose 8-roller pump heads for low pulsation.
Change your cassettes easily, even during operation – there are no restrictions.
Cassette adjustments and changes are simple, just click in place.
No additional purchase of a pump drive needed: upgrade your single-channel pump drive with just one adaptor for multi-channel use and pick the head/cassette configuration that matches your application needs.

The bio-specialist for a gentle and efficient result on a larger surface

The shaker platform with flat rubber mat 2000 included in the scope of delivery increases the plate area by 71.5% compared to the Hei-SHAKE Rock Core.

Thanks to the 2D-rocking movement and a speed range of 1 – 80 rpm, more vigorous but continuously gentle shaking of the samples is ensured. Containers have a secure grip on the anti-slip rubber mat even at high speeds.

Your applications can be carried out in continuous operation or by means of a timer. The integrated timer function (1 min to 999 h 59 min) and RS 232 interface enable unsupervised operation, so that you can attend to other tasks without a worry. The device activation and partly automated processes can be carried out remotely via the connection to the PC or via server-based software, e.g. Hei-PROCESS. In addition, the automatic restart, e.g. after power failures, can be set with the user-friendly menu structure.

Two variants of this device are available: with a tilt angle of 10° to prevent foaming and 5° to prevent additional risks such as glass breakage and spill over of liquids.

Scope of delivery: Shaker incl. flat rubber mat 1000 + set for upgrading to platform 2000 incl. flat rubber mat 2000
