The 3VVN1-3M(N) water ring vacuum pump with a capacity of 3.5 m3/min at an initial pressure of 0.04 MPa is designed for general industrial use, to create and maintain a vacuum in the operating pressure range from atmospheric to 10 kPa. The working fluid of the pump is water. The use of the 3VVN1-3M(H) pump for pumping out water-gas mixtures is allowed only if the bulk of the water is separated and discharged at the pump entrance. Failure to comply with this requirement may lead to unacceptable overload of the engine and destruction of the pump's working organs. The 3VVN1-3M(H) water ring vacuum pump is not intended for use in fire and explosion hazardous industries. The 3VVN1-3M(H) vacuum water ring pump is manufactured in the climatic version of UHL 4 and O4 (i.e. for moderate and cold climate) according to GOST standard 15150-69, meets the requirements of technical specifications TU 3648-053-00218526-2013, designed and manufactured taking into account the requirements of GOST R 52615-2006.

The Korsa NV-1500 SHV-PB laboratory fume cupboard is a single—frame cabinet with a width of 1410 mm with a table top made of polypropylene. External dimensions of the cabinet (W×D×H): 1410×700×1960 mm. Dimensions of the working area (W×D×H): 1378×540×750 mm. Table top: polypropylene. A reliable fume cupboard for laboratories Working surface material: monolithic polypropylene. It is moisture-resistant, resistant to prolonged exposure to concentrated acids, alkalis and organic solvents. Poorly resistant to high temperatures. Polypropylene countertops are suitable for chemical laboratories that work a lot with concentrated inorganic acids and alkalis. The working area is closed by a single lifting frame with a counterweight. It has two exhaust zones: the hood of the exhaust box and the level of the countertop. Diameter of the flange for connection to the ventilation system: 150 mm. Working area size (W×D×H): 1378×540×750 mm. Please note that the cabinet narrows upwards. At a height of 50 cm, the depth of the working area will be 410 mm, at a height of 70 cm: 365 mm. If you need to place high equipment, then make sure that it corresponds to the dimensions of the camera, otherwise you will not be able to close the cabinet. The height of the raised glass above the cabinet: 510 mm, that is, with the glass raised, the total height of the cabinet will be 2470 mm. The working area is illuminated by an LED lamp (included in the package). The switch is located on the right-hand side of the cabinet, next to the sockets. The fume cupboard is equipped with two sockets, one of them with grounding. Sockets have the IP20 degree of protection, maximum load: 1.5 kW. The base of the cabinet is an all-welded metal frame in powder coating. The side laminated panels (chipboard 16 mm thick) are edged on the facade with a durable PVC edge 2 mm thick, which increases their impact resistance and mechanical strength. The cabinet legs are adjustable in height within two centimeters, allowing you to place the cabinet even on a rather uneven floor.

Petri dish PrimeLab 100 mm, glass - round laboratory glassware with a small rim around the perimeter. Its design is well thought out: the diameter of the top part (107 mm) is slightly larger than the diameter of the bottom part (100 mm), making it easy to slide over the base to protect the contents from the elements. Their height is 20 mm. The container is made of transparent tempered glass, which allows you to observe all the processes inside without opening the top part. Designed for reusable use and sterilization under appropriate conditions.
