No prior knowledge is required. Just start the program, select a SOP and add the sample – the rest takes place completely automatic. Your advantages with the Analysette 22 NanoTec include: •  Measurement even of nano parti- cles in an extremely wide measuring range of 0.01-2100 µm. • Fast, automatic particle size analysis. •  Simple measurement with short measuring times. •  Especially high measurement pre- cision due to the analysis of 110 channels. • Consistent reproducibility – reliable comparability. • User-friendly operation. •  Quick change between wet and dry measurement. • Fast and simple cleaning. • Short analysis times. The very large measuring range from 0.01 µm to 2100 µm of the Analysette 22 NanoTec results from the combina- tion of two lasers with two different measuring cell detector spacings: Large particles are detected using an infrared laser with a large distance to the mea- suring cell, for small particles a green laser with a small distance to the cell is used, which permits the detection of the forward scattered light up to a scatter- ing angle of 65 degrees. The measurement of smallest particles down into the nano range is performed by the green laser light for backward scattering. Specially arranged detec- tors ensure this. Especially convenient: The total measuring range of 0.01 to 2100 µm in the Analysette 22 NanoTec can be detected without converting the optical elements. The result: perfect measurements with outstanding reli- ability, meaningful comparability and consistent reproducibility. Fritsch, Midwestern Industries' Electro-Lift Platform Provides Faster Screen Changes Midwestern Industries Inc. launched its Electro-Lift separator screen-chang- ing system. The ergonomically designed lift system is electrically powered to assist in making separator screen changes easier, faster and safer. Engineered with a 120-volt sealed gear- driven system, operation is as simple as plugging into any convenient outlet and pressing a switch. Quality built and engineered in the United States, the Electro-Lift is adapt- able to fit a variety of different frame deck configurations. While it is designed to lift the frames of Midwestern Indus- tries' round separators, most makes and models of competitors round sepa- rators can easily convert to this system. The system's ergonomically designed configuration assists with the lifting of separator frames to eliminate the need for two people to remove each frame – making screen changes virtually a one- man operation. Typically, screens must have hands on them when changing out. However, Electro-Lift is mounted inde- pendently to the frame so there is no need for it to be locked out when you are working under them with your hands. This engineering versatility also allows operators to change screens and gain access to the interior of the unit for cleaning or inspection, which is expo- nentially faster than using comparable systems. The system can also be used to inspect the screens to ensure quality control. Ultimately, the system changes screens faster with no lifting of heavy frames, which drives the Electro-Lift system's key attribute of reducing downtime to a minimum. Safety is an integral part of the 120- volt Electro-Lift as it leverages a sealed gear-driven system, which ensures the frames will not drift down when changing your screens – even if the power fails. Unlike traditional hydrau- lic or pneumatic changing systems, if the power does go out during screen changes, the frames will not fall. Because the unit is 120 volt, it can be plugged into any convenient outlet, which eliminates the need for custom- ers to provide compressed air. Whereas most competitive versions will use some form of clamping device if power is lost, Electro-Lift uses two mechanical screws powered by the actuator. Additionally, there are no cumbersome hoses to deal with, and the sealed system eliminates the need for greasing which makes it environ- mentally cleaner. Midwestern Industries' Electro-Lift is competitively priced vs. traditional alternatives, and delivers the following essential configuration advantages: •  Adaptable to multiple deck configurations. • Faster screen changes help to reduce downtime to a minimum. •  Sealed gear driven system ensures safe screen changes every time. •  120-volt electrical can be plugged into any convenient outlet. • Frames will not fall or come down if power fails during screen changes.
