The main difference between this set-top box and the universal set-top box of the NPVO and ZDO is that a prism is used as a working element of the MNPVO, which allows to obtain several reflections from the area of contact with the sample under study, which leads to an improvement in the quality of the spectrum and an increase in the sensitivity of the method (absorption bands become more pronounced). The registration of specular and diffuse reflection spectra (ZDO) is not provided on this set-top box. The MNPVO prefix is effective in registering the absorption spectra of samples whose dimensions (number) are sufficient to ensure contact with the entire area of the working face of the prism: * liquids of any degree of viscosity (solutions, suspensions, oils, etc.); * solid elastic samples (polymer fragments of sufficiently large size, rubbers, plastics, etc.); * powdered samples in quantities sufficient to be applied to the entire surface and samples in the form of thin tapes; The universal clamp is equipped with a precision lever mechanism for quickly lowering the tip and a micrometer screw that allows you to pre–set the optimal degree of pressure - this ensures quick sample change and repeatability of the results during measurements. For convenience when working with liquid and paste-like samples, it is possible to rotate the clamping console by 180o. Note: the MNPVO prefix does not exclude the possibility of registering the spectra of samples whose dimensions are smaller than the area of the working face of the prism (the presence of a visual inspection system of the surface under study increases convenience when working with small-sized objects), but the overall effectiveness of the method is significantly lower than when using the universal NPVO and ZDO prefix.

Laboratory fume hood Kors NV-1200 SHV-SPB is a single—frame cabinet with a width of 1100 mm with a countertop made of chemically resistant plastic. External dimensions of the cabinet (W×D×H): 1100×700×1960 mm. Dimensions of the working area (W×D×H): 1068×540×750 mm. Table top: chemically resistant plastic. Reliable fume cupboard for laboratories Working surface material: chemical resistant plastic. It is moisture-resistant, resistant to prolonged exposure to concentrated acids and alkalis. It has a limited resistance to high temperature and to prolonged exposure to organic solvents. It is often chosen for laboratories and is suitable for training workshops, analytical and medical laboratories. Ovens or drying cabinets should not be placed on such a countertop. 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): 1068×540×750 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 side of the cabinet, next to the sockets. The fume cupboard is equipped with two sockets, one of them with grounding. Sockets have thee 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 with a thickness of 16 mm) are edged with a durable PVC edge with a thickness of 2 mm, 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. What are the other options? There are larger cabinets with a countertop made of chemical-resistant plastic: NV-1500 SHV-SPB, NV-1500 SHVD-SPB and NV-1800 SHVD-SPB.

It is intended for taking samples of biological material, with the possibility of their subsequent safe transportation to the laboratory for analysis. Non - sterile

The NV-800 SPr cabinet for devices with 2 glass doors. The cabinet is made of laminated chipboard with a 2 mm shockproof PVC edge on the facade. Included in the set: 2 glass doors for the upper compartment; 2 doors for the lower compartment; 4 shelf inserts; metal legs 100 mm high.

TDS-2 is a syringe (see Fig. 1), which is installed on the evaporator of the chromatograph. The device is equipped with a crane that cuts off the carrier gas line when removing the rod with the sorption tube from the thermal desorber. When the tap is open, the stem is lowered to the lower position and the sorption tube is inserted into the evaporator brought to the desired temperature. In the conditions of the upper position of the rod, it is also possible to displace air by purging the sorption tube with a carrier gas. Technical characteristics of TDS-2 The heating time to the desorption temperature is no more than 1 sec. The cooling time when moving to a cold zone is no more than 10 seconds. Outer diameter 5-0.1 mm Dimensions of the sorbent chamber: diameter 3.4+0.3 mm length 52 mm (470 µl) Volume (for solid samples) 90 µl Operating temperature ranges* from 50° to 400 °C Overall dimensions (height with the rod fully extended) 320 mm. Weight 0.325 kg.
