The NVSp-4 dry vacuum spiral pump can operate continuously at an inlet pressure of no more than 10 kPa (75 mm Hg), pumping out one or more sealed vessels with a total volume of no more than 0.7 m3 from atmospheric to residual pressure during the day. Pumping of vessels of the specified volume with leakage is allowed, but the leakage should not cause an increase in pressure at the pump inlet of more than 10 kPa (75 mm Hg).

The 2ZVE-250R shutter is pendulum-type. The 23VE-250R shutter is manufactured in the climatic version UHL (i.e. for moderate and cold climate) and O (i.e. general) 4 according to GOST standard 15150-69. The working environment is air and non–aggressive gases. It is not intended for use in fire and explosive hazardous industries. The 23VE-250R shutter meets the requirements of technical specifications TU 3648-040-00218526-2003. According to the method of protecting a person from electric shock, the gate belongs to Class I electrical equipment according to GOST 12.2.007.0-75.

Vacuum resistance furnaces are necessary for heating products before pressure treatment, for sintering, degassing, quenching, annealing, soldering and chemical-technological processes. Such furnaces among all the variety of thermal equipment are considered the most environmentally friendly – heat treatment is carried out at t up to +2500 ° C in a purified vacuum. Under certain conditions, vacuum furnaces are used to work with neutral gases. The outer part of the furnace is made of stainless steel and is cooled by liquid. The inner part of the working chamber, where the heat treatment of materials is carried out, is made of an alloy of molybdenum and tungsten. The components are characterized by a low inertia force, reduced gas separation. The settings are available on the control panel, where the instruments, automatic and manual control switches are located. At every enterprise of the electronic industry, nuclear power, an explosion-proof vacuum resistance furnace is needed. The same applies to areas where various products undergo heat treatment at the stage of production and preparation for use.

It provides clear visibility of the labels of viscometers located in the thermostat bath. This creates additional convenience and increases the accuracy of measurements.

BASIC EQUIPMENT The base is a collapsible frame made of rectangular steel profile, painted with powder paint (RAL 7035) with the texture of shagreen leather Hidden fasteners Two easily removable rear screens (RAL 7035) and one non-removable (RAL 5023) Rear side boxes Adjustable supports (0-40 mm)

The Kors NV-1600 SHVp laboratory fume cupboard is a single—frame cabinet with a granite countertop with a width of 1544 mm and a porcelain apron. This is a specialized cabinet for placing heating devices: muffle furnaces, drying cabinets, laboratory stoves. External dimensions of the cabinet (W×D×H): 1600×888×1960 mm. Dimensions of the working area (W×D×H): 1544×660×1072 mm. Table top: granite tiles. Safe operation with laboratory furnaces The working surface and part of the working area are lined with granite tiles. The tile is moisture-resistant and perfectly withstands high temperatures. It is resistant to prolonged exposure to concentrated acids, alkalis and organic solvents. Limited resistance to hydrofluoric acid. This is one of the most popular types of countertop materials for laboratory furniture. Height of the protective apron: 600 mm. Working area dimensions: 1544×660×1072 mm. Furnaces or cabinets up to 650 mm deep can be placed in the draft. The working area is closed by one 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. The fume cupboard is equipped with two sockets. Sockets have the IP20 degree of protection, maximum load: 4 kW. A reliable fume cupboard for heavy equipment placement 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.
