The body of the 50M URS valve is of welded construction and consists of a shell, a seat, side and lower nozzles. The lower branch pipe of the 50M URS valve is connected to the vacuum system using welding. The smooth part of the stem serves as a visual indicator of the "open" or “closed” valve positions. The casing is designed to protect the valve from accidental openings, and also serves as additional protection against precipitation, sand, dust entering the inner cavity of the valve. The valve opens when the flywheel rotates counterclockwise. The valve closes when the flywheel rotates clockwise.

Silicone hose with an inner diameter of 8 mm is used to connect circulation coolers A160 and A300 with thermostats of the W series or to external consumers.

The M532® Raman microscope combines the capabilities of the Inspectr R532® Portable Raman Express Analyzer and the U300M microscope, adapting it for both transmission and reflection measurements. The wide functionality of the M532 microscope makes it possible to find and analyze individual particles with a size of 2-3 µm among many similar ones with similar physical and chemical properties, which opens up new research opportunities within the framework of a single Raman system. A spatial resolution of 1 µm and a spectral resolution of 4-6 cm-1 ensure excellent measurement accuracy and reproducibility. The compact design and portability of the instrument allow for high-quality and instant analysis of substances without sample preparation, which makes the M532 microscope an indispensable instrument for a wide range of studies. Equipped with a motorized slide (optional) with a step of 0.36 µm, the M532 microscope scans the surface of the sample, recognizes substances in multi-component heterogeneous mixtures and creates a graphical image of the intensities of Raman scattering characteristic lines at various points on the surface (2D mapping), which makes the M532 microscope the most advantageous in terms of price-quality ratio scanning Raman microscope in the world market.

NV-1210 PC is a wall table with a superstructure in the NV line. The table top is made of monolithic ceramic with a depth of 70 cm and a width of 121 cm. A lamp and two sockets are built into the superstructure. It is designed for standing work: the height of the table top is 85 cm. External dimensions of the table (W×D×H): 1210×700×1650 mm. The table top made of monolithic ceramics is moisture-resistant, perfectly withstands high temperatures. It is more resistant to chemicals and heat than ceramic tile since there are no seams. The superstructure allows you to compactly place the necessary reagents and laboratory utensils next to the workplace. Its depth is 25 cm, and its height is 80 cm. The working area is illuminated by a fluorescent lamp (included in the package). The switch is located on the left-hand side of the superstructure. There are also two sockets, one of which is grounded. Sockets have the IP20 degree of protection, maximum load: 1.5 kW. On the right-hand side under the table top there is a built-in cabinet with three drawers. You can store laboratory utensils, equipment accessories or other small things there. The side laminated panels of the table (chipboard 16 mm thick) are edged with a 2 mm PVC edge, which increases their impact resistance and mechanical strength. The legs of the table are adjustable in height within two centimeters, allowing you to place it even on a rather uneven floor. Advantages of NV-1210 PC tables The working surface is made of monolithic ceramics. It is convenient to work while standing: the height of the working surface is 85 cm. On the shelves and in the drawers of the table you can store accessories to the devices on the table, laboratory utensils or reagents. Application of NV-1210 PC tables Tables of the NV series are used in laboratories of the widest profile: at food and light industry enterprises, in scientific and educational workshops, in chemistry classrooms, quality control centers, medical organizations and many others.
