Green fluorescent protein (GFP) isolated from the jellyfish species Aequorea Victoria, consists of 238 amino acids with a molecular weight of about 27 kDa. GFP is characterized by two absorption peaks in blue light at 395 nm (major) and 475 nm (minor) and a fluorescence peak at 498 nm in the green range. At present, the gene for this protein and proteins derived from it, glowing with different colors, is used as a luminous marker in cell and molecular biology to study protein expression in cells and living organisms in vivo. GFP also allows purification of recombinant proteins, where GFP or its derivatives are used as an affinity label.

It consists of a digital contact thermometer TK-5.27 complete with a submersible high-temperature probe, designed to measure the temperature of metal melts in the range of +600 ° C ... +1800 ° C. The digital contact thermometer TK-5.27 is equipped with the function of recording measurements in the device's memory, followed by transferring data to a computer and providing reports in the form of tables and graphs. To measure the temperatures of metal melts, disposable thermocouples of the PPR (B) type with a protective tube length of no more than 900 mm are used. The kit is adapted to the replacement blocks of EVRAZTEMP ET-V-09-00. •

The CR-1B reactor is an automated chemical reactor with thermostat, stirrer and reagent management system. To control the reactor, specialized software is used (supplied with the reactor). This reactor may be of most interest for laboratory research for routine synthesis of nano/microparticles (e.g. vaterite), as well as experimental scaling tests with a view to further transferring it to production facilities.

during the control of maximum permissible concentrations in atmospheric air, in the air of the working area, during technological control of air purity of objects for various purposes, in the air of the sanitary protection zone, industrial emissions, emissions into the atmosphere.For measurements at low temperatures, an isothermal (thermo) bag can be included in the standard package at the request of the Customer for an additional fee.

The NV-750 VG is a specialized laboratory table with a damping concrete slab on a sand cushion. It is used to keep sensitive analytical equipment, primarily scales. The table is designed for sitting work. Dimensions when assembled (W×D×H): 750×600×750 mm. The size of the countertop for scales: 400×400 mm. Special anti-vibration design The three-layer design of the table allows you to maximally dampen vibrations that prevent the accurate operation of the scales: 1st layer: sand cushion. The main countertop has a built-in drawer open from above, which contains a sand cushion. 2nd layer: concrete slab — weighting. A heavy concrete slab is placed on a sand cushion. 3rd layer: a small table top. The small table top is attached to the concrete slab, completely covers it and does not come into contact with the main table top (and, therefore, does not transmit vibrations from it). The size of anti-vibration (small) table tops: 400×400 mm. For maximum isolation from vibrations, the scales should be placed in the center of this countertop. Table base: all-welded metal frame, painted with white powder paint. The design does not use rubber dampers, which have a limited service life. Both countertops are made of laminated chipboard. It is well suited for the placement of devices, but is not resistant to concentrated acids, alkalis and organic solvents. The damping surface protrudes above the main tabletop, but visually it does not differ from it in any way. The countertops and side laminated panels (chipboard 16 mm thick) are edged with a durable PVC edge 2 mm thick, 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.
