Leybold Heraeus DIVAC 2.4L Vacuum Pump Vakuum Pumpe

Deliver precise vacuum and offer widely diverse control functions for a huge range of applications i (more)n the laboratory. The intuitive user guidance on the hand terminal ensures ease of operation; the process parameters can be entered over a touchscreen and a rotation knob. Ajustment capabilities: Units of measurement The operating language The operating mode Parameters, such as the setpoint pressure or suction capacity of the system direct over rotation knob. Depending on the selected operating mode, the graphic display of the hand terminal then indicates the respective process variables. The user can intervene in the ongoing process at any time with the hand terminal and its integrated touchscreen and rotating knob. The hand terminal can be located via vacuum pump system (paging); the hand terminal will answer with a signal tone. Four operating modes: Evacuate – The vacuum pump system evacuates a vacuum chamber with adjustable pump capacity. Pressure control – The vacuum pump system controls the system pressure to the set value (constant pressure). Automatic – The vacuum pump system automatically finds the vapour pressure of the sample and adjusts the process pressure accordingly. Individual pressure function – The vacuum pump system controls the process according to a user-defined pressure curve. The setpoint pressure and the opening and closing of the coolant valve (accessory) on the high-performance condenser can be easily entered for a range of set times. A repeat function allows successive repetitions of the programmed pressure curve.At any time during an active process, you can switch to manual process control. Functions for Evacuate and Pressure control will be available simultaneously.

Heidolph Hei-FLOW Ultimate 600 Peristaltic Pump The ability to switch between precise dosing and fas (more)t conveying make this pump model the perfect complement to a reactor system. With a flow rate of 2.0 - 4,056 ml / min, when operated with single-channel pump heads, flows from feed-batch and chemostat modes of operation can be conveyed precisely. Rapid filling and emptying of the reactor system is also possible. In addition to the selectable process parameters - speed, tubing diameter, flow quantity display, dosing volume, interval dosing and break times - the pump conveying characteristics are stored in the program. Thanks to the analogue and digital (RS 232) interfaces, processes can be automated. All media is conveyed with a control accuracy of ±2% at a speed of 24 — 600 rpm. An optional foot switch can be connected for dosing by foot pressure.

The HX5.EX scale is a modern weighing instrument assuring fast and reliable measurement in hazardous (more) areas classified as zones 1/21 and 2/22. To ensure precision and excellent measurement repeatability, high quality electronic components are used. The weighing platforms offered in wide range of dimensions and maximum capacities, this combined with excellent metrological parameters enables easy selection of an instrument that meets the most demanding requirements. Standard version of the scale is equipped with 2 serial, intrinsically safe RS232 communication interfaces, and with one RS485 interface. They facilitate cooperation with equipment intended for operation in hazardous areas. Possibility to add digital inputs/outputs extends the range of instruments compatible with the indicator by automatic elements compliant with ATEX directive. More demanding customers can use the IM01.EX module, installed in the safe area, which extends the available connectors by Ethernet, USB, 4-20mA/0- 10V analog outputs, Profibus DP and additional digital inputs/outputs. This enables cooperation with external devices: barcode scanners, printers, external displays, control buttons, light signalling towers, other controlling/signalling devices, systems for automatic process control and superior IT systems. Scale operation requires use of a dedicated PM01.EX power supply, which is not a standard scale component. To operate the scale, order a selected type of the dedicated intrinsically safe power supply. Power supply types: PM01.EX-1 - power supply for operation in ATEX area. Used when it is required to connect the power supply to voltage source placed in hazardous area. PM01.EX-2 - power supply for operation outside ATEX area. Used when power supply connection to voltage source is carried out outside hazardous area. Complex software enables carrying out many tasks connected with mass measurement, e.g. parts counting, checkweighing and statistics. The scales feature user-friendly graphic interface, which can be customized using widgets. This and the large colour display of high resolution guarantee easy and clear transmission of data on current process. Colour bar graph significantly influences performance by signalling whether the weighing result is within declared thresholds or not.
