Heidolph Hei-TORQUE Ultimate 400 w/ USB & RS232 Interface Overhead Stirrer-cover
Heidolph Hei-TORQUE Ultimate 400 w/ USB & RS232 Interface Overhead Stirrer

Heidolph Hei-TORQUE Ultimate 400 w/ USB & RS232 InterfaceThe Hei-TORQUE Ultimate 400 laboratory  (more)stirrer is ideal for the powerful stirring of viscosities up to 250,000 mPas or volumes up to 100 liters (H2O). Thanks to its 2-gear stage design, it stirs particularly powerfully in the speed range up to 400 rpm and is therefore particularly suitable for applications with highly viscous media that require mixing in the lower speed range. However, operation at speeds of up to 2,000 rpm is also possible in the second speed. In addition, the Hei-TORQUE Ultimate 400 offers, above all, the possibility of ramp programming, process monitoring (including timer function, torque trend display as a value), as well as the necessary equipment for documenting your application parameters. For this it is equipped with two interfaces - USB and RS232 - which give you the greatest flexibility to connect the device to a PC, a programmable logic controller (PLC) or an automation system such as e.g. LabManager. The scope of delivery includes the free Hei-Control software for remote control of up to 4 devices via PC. The laboratory stirrer Hei-TORQUE Value 400 performs every stirring task with minimal noise thanks to the latest engine technology. The safety-related start/stop touch-function serves to minimize the risk of unintentional switching on. Suitable for use in fume hoods or as a drive for reactor superstructures, the Hei-TORQUE Ultimate 400 has a quick-action chuck (quick chuck with safety ring) with a diameter of 10.5 mm, which can be combined with a large number of stirring tools for the best stirring results. *Stand, clamp, and impeller are sold separately* Click Here to View Product Video INCLUDED: The Heidolph Hei-TORQUE Ultimate 400 w/ USB & RS232 Interface includes: - Power Cord - Operator's Guide - Full 3 Year Manufacturer's Warranty

Heidolph 036110233 Hei-PLATE Mix 'n' Heat Ultimate Hotplate Stirrer, 135mm Plate

Heidolph 036110233 Hei-PLATE Mix 'n' Heat Ultimate Hotplate Stirrer, 135mm Plate The Heidolph 036110 (more)233 Hei-PLATE Mix 'n' Heat Ultimate Hotplate Stirrer, 135mm Plate paves the way for future-oriented working practices: thanks to its equipment with numerous interfaces, it meets all requirements for digitalization and network. The RS232 and USB B interfaces allow control via our Hei-Control software, free of charge, as well as our Hei-PROCESS solution. With the LAN interface, you can directly integrate the device into a network, whereas the USB A interface located at the front allows data logging via USB stick. Use the USB C interface and combine the magnetic stirrer with the electric Heidolph Lab Jack to work even more comfortably and securely. For controlling the temperature, you can choose between three heating modes: FAST for a particularly quick heating, as well as PRECISE and PRECISE+ for a particularly exact control of your target temperature without overshoot - this is how sensitive samples are optimally protected. Therefore, the device is compatible with the temperature sensor Pt1000 as well as the double sensor Pt1000 that allows the measurement in your sample and in the bath liquid simultaneously. The possibility to program ramps and to create profiles gives you full control and increases the precision and reproducibility of your experiments. For the stirring speed, there is a three-stage setting (start-up behavior). Furthermore, you can set the rotational direction of the magnetic stirring bar and benefit from the automatic stir bar detector. As a result, your sample is optimally stirred at any time, even when there are irregularities while stirring. This magnetic stirrer is equipped with the most important safety features. The large safety distance between the heating plate and the control panel, as well as the visual residual heat indicator at temperatures 50°C, protect against burns. The patented Kera-Disk® plate made of anodized aluminum is chemical-resistant, scratch-resistant and has a diameter of 145 mm. This unique size makes it suitable for use with many accessories and samples on a small footprint. Moreover, the material used allows the fastest heating times.
