KNF LABOPORT vacuum pump system SC 840 G
The KNF LABOPORT vacuum pump system SC 840 G is a versatile and durable vacuum pump solution that is ideal for use in laboratory environments. Thanks to its automatic boiling point detection with efficient ramp function and high recovery rate even with low-boiling solvents, it offers a clear advantage over conventional pump systems in terms of precision and safety. Similarly designed devices such as the [ILMVAC Vario Elite vacuum pumping unit] present comparable performance data, but this system is further distinguished by its intuitive touchscreen operation and integrated wireless remote control.
Functionality and technical features
Precise control ensures reliable operation under vacuum conditions. Boiling points can be readjusted manually if necessary, but in practice the ramp function takes over the adjustment automatically. The integrated gas ballast valve ensures that the delivery rate remains constant even in demanding applications. The most important technical and equipment points are as follows:
- Delivery rate: 34 l/min at atmospheric pressure
- Ultimate vacuum of just 6 mbar absolute (ideal for sensitive products)
- Integrated speed control for accurate vacuum control
- Electrical parameters: 100-240 V, 50/60 Hz, max. 100 W power consumption
- Control and display: touchscreen with rotary push button and wireless remote control
- Pump head made of TFM PTFE, diaphragm PTFE-coated, valves made of FFPM
- ATEX conformity in accordance with II 3/-G Ex h IIB+H2 T3 Gc (internal atmosphere)
These features allow the system to be used flexibly without compromising on safety. In addition, USB-A and USB-Mini ports are integrated into the controller, allowing software updates or wired operation to be implemented quickly.
The system is equipped with a thermal switch and a mains fuse, which protects against overheating during continuous long-term use. At the same time, a practical battery function optimizes the use of the handheld terminal. It can be operated autonomously for up to eight hours, while it can be recharged wirelessly on the charging station. The option of using the hand-held terminal outside of closed fume cupboards or at a great distance from the system significantly increases safety in the laboratory. The user-friendly combination of touchscreen and rotary knob as well as the clear menu layout also make it easy to set all pump options.
The robust housing and IP30 protection concept ensure that the vacuum pump system can be used in both academic laboratories and industrial research and development facilities with a long service life, reliability and low maintenance. The materials used - in particular the PTFE in the pump head and the FFPM valves - are highly resistant to chemical influences, which makes it possible to handle aggressive chemicals or solvents.
Examples of applications
- Distillation of temperature-sensitive substances such as methanol, ethanol and acetone, where a very precise vacuum is essential.
- Rotary evaporator applications in chemical synthesis laboratories, where the high solvent recovery rate is beneficial.
- Filtration processes in pharmaceutical development, where the stable ultimate vacuum ensures repeatable results.
- Extraction processes in petrochemical analysis where explosive atmospheres can be safely handled due to ATEX compliance.
FAQs
Can the system be operated with different voltages?
Yes, it has been designed for 100-240 V at 50/60 Hz, which allows universal use.
Does the radio remote control always have to be in operation?
No, it can be used either via Bluetooth or via the USB mini interface. If required, it can also be controlled completely via USB cable if the radio signal is disturbed in bulky laboratory setups.
How often is maintenance of the pump head recommended?
The maintenance intervals depend on the intensity of use and the chemicals used, but are usually several months apart. PTFE and FFPM are very wear-resistant, which means that only very short intervals are required.
How is it ensured that no contamination of the process media occurs?
The pump head and the diaphragms are made of chemically resistant materials. These significantly minimize the risk of contamination by preventing the penetration of aggressive media.
Conclusion
This vacuum pump system impresses with a combination of high pumping capacity, reliable boiling point detection and precise vacuum control. Users also benefit from a robust design, safe ATEX concept and extensive control options via radio and touchscreen. This makes the SC 840 G a tried-and-tested tool for laboratories and research institutes that require precise, reproducible results with maximum process reliability and user-friendliness.
