Description by the supplier

Technical Specifications:

The device provides a maximum flow rate of 34 l/min while ensuring a final vacuum of 8 mbar (absolute) and features a pressure capacity of up to 1 bar (relative). The pump operates effectively within the permissible fluid temperature range of 5-40°C. The valves constructed from FFPM (fluoroelastomer), diaphragms coated with PTFE (polytetrafluoroethylene), and the pump head made from PTFE offer strength and durability.


This laboratory equipment is versatile with significant applications including rotary evaporation, degassing, gel drying, and facilitating the function of a vacuum oven.


The pump boasts an operation that is impeccably clean and 100% oil-free, ideal for maintaining a sterile laboratory environment. Its chemically-resistant PTFE/ FFPM flow path makes it suitable to work with extremely aggressive and corrosive gases and vapors. The compact design along with its silent and reliable operation make it practical for any laboratory setup. Moreover, with zero maintenance requirement, it is relatively hassle-free. The equipment is ATEX-compliant for internal atmosphere only (Ex) II 2 / -G IIB + H2 T3, maintaining high safety standards.

Chiller Microcool MC 1200 LAUDA

Circulation chillers for reliable continuous operation in laboratory and research applications from  (more)-10 to 40°C The LAUDA Microcool line, simple, easy to use, consists of four compact models with large LED display and membrane keyboard, which offer cooling capacities from 0.25 to 1.2 kW. The strong point of these devices is the high-quality centrifugal pump with magnetic coupling - unique on the market for this price category: the magnetic coupling of the pump and the electric motor prevents any kind of sealing problem on the pump shaft. The MC 250 and MC 350 models easily fit on a laboratory bench. Larger models MC 600 and MC 1200 with 600 and 1200 watts of cooling capacity are also available, which can be placed on the floor or under a laboratory bench to save space. In addition, the MC 1200 W, the most powerful device, is also available in a water-cooled version. Notable features - Auto start timer and auto power off function - Top filling opening, drain connection on the back - Cooling capacity adapted via solenoid valve control, including automatic compressor control Examples of specific applications - Rotary evaporators - Distillation systems - Spectrometers - Supply of cooling traps - Digital print - Laser cut - Spot welding - Injection molding - Tunnel drilling machines - Centralized cooling water supply Accessories included Nozzles for pump connections; screw cap Performance graph of the pump of the LAUDA Microcool CHILLER.
