Manufacturer Name: Goldbrunn 450 Vacuum dryer Vacuum dryer from the German manufacturer of professional laboratory equipment GOLDBRUNN made of high-quality components that ensure long-term and trouble-free operation. The vacuum dryer is used for gentle, thorough and very fast drying of oxidation-sensitive materials: samples, electronic components, laboratory glassware, flammable solvents, etc. Tight closure and lack of air circulation inside allows for drying powdered materials and granulates. The use of vacuum has eliminated the oxidation of active substances, and the hermetic seal protects the material from external contamination. Thanks to the possibility of precise temperature setting, it is suitable for tasks in pharmaceutical, biotechnology, university, cosmetic laboratories, as well as in research laboratories of various companies, e.g. mining laboratories. Reduced drying time (no condensation) is provided by the vacuum generated inside the chamber. A pressure lower than the ambient atmosphere is created in the chamber – up to a maximum of 133 Pa (0.00133 bar). The vacuum has the effect of significantly accelerating the drying process. Removing air from the chamber increases the level of safety when processing delicate samples without causing limescale and deposits. The vacuum dryer uses a PID digital temperature controller, which allows the temperature inside the chamber to be precisely maintained at a constant level (up to 250 deg; C). The heating intensity can be adjusted to 0.1 deg; C. The heavy-duty aluminum shelf in the compartment can be easily inserted or extended. The airtight door is equipped with a vision window made of pressure-resistant, double glass to protect against heat loss and implosion. The spacious vacuum chamber (with a capacity of 20 liters) is made of durable, anti-corrosion stainless steel that is also resistant to chemical agents. Easy cleaning of the chamber is ensured by smooth interior surfaces and rounded joints. On the side wall of the device there is a vacuum pump connection valve with a Ø of 16 mm. A vacuum pump is not included with the device.
