Thrombopoietin is a glycoprotein hormone synthesized mainly in the liver, the main physiological regulator of platelet production. Participates in the development of precursors of other blood cells. TPO and other TPO receptor agonists are promising therapeutic agents.

The principle of operation of the device The principle of operation of the irradiator is based on the conversion of DC electrical energy into a normalized flow of ultraviolet radiation in the optical wavelength range of 350 ... 400 nm with a maximum at a wavelength of 365 nm. Design features and advantages The irradiator is a lantern consisting of an ultraviolet diode placed behind the focusing system, connected to a DC voltage converter, which supports the optimal mode of starting and functioning of the LED. Structurally, the irradiator is made in a lightweight duralumin housing, in the front of which there is a focusing system with an ultraviolet LED. The housing is equipped with a carrying strap. There is also a power on/off button on the case. As the power source of the irradiator, a lithium-ion battery of type 18650 with a nominal voltage of 3.7 V or 3 AA batteries with a voltage of 1.5V. are used. An ultraviolet LED is used as a source of ultraviolet (UV) radiation. The use of an LED distinguishes the UFO-3-20F irradiator from similar devices using UV lamps, it provides: high reliability and durability; variable diameter of the UV radiation zone; low current consumption and long continuous operation time; instant readiness for the first and subsequent turn-on; low weight, compact; high radiation intensity; stability of the characteristics of the irradiator, both during operation and throughout its entire life; wide operating temperature range. Scope of application The UV-3-20F irradiator (lantern) is used for ultraviolet irradiation of the surface of various parts, assemblies and mechanisms during flaw detection by fluorescent methods of non-destructive testing at machine-building enterprises, chemical and petrochemical industries, railway, automobile, water and aviation transport, during the laying and operation of pipelines, in construction, agriculture. The device can be used to check the quality of welds and internal surfaces of closed tanks. The luminescent method makes it possible to ensure high brightness and contrast of the indicator pattern, and, consequently, high sensitivity, especially on parts and products with a dark surface. Technical specifications The range of radiated wavelengths, nm 350...400 Ultraviolet irradiation at a distance of 300 mm, W/m2, not less than 20000 with a diameter of the irradiated area of 100 mm not less than 2000 Power supply from a lithium-ion battery type 18650 voltage of 3.7 V, or 3 AA batteries with a voltage of 1.5V Continuous operation time without recharging the battery, h, at least 4 Maximum irradiance at the wavelength, 365 nm Dimensions (diameter x length) 40 x 150 Weight (without batteries), kg, not more than 0.2

NV-1200 Ln are laboratory tables with a metal frame and a tabletop width of 1090 mm. They are designed for sitting work (the height of the table is 750 mm, this is the height of a regular office desk). The NV-1200 tables have a metal frame painted with durable powder paint. The side laminated panels (chipboard 16 mm thick) are edged on the facade 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. Dimensions of the table assembled (W×D ×H): 1090×700×750 mm. The working surface for your tasks We offer laboratory tables with various working surface materials. Version: Countertop NV-1200 LLn: Laminate. A budget solution, suitable for school chemistry and physics classrooms, office work, placement of devices. NV-1200: LSPn. Chemically resistant plastic. A good choice for training workshops, analytical and medical laboratories. It does not tolerate high temperatures well, heating devices should not be placed on the surface. NV-1200 LKn: Porcelain tile. A practical solution for most chemical, biological, medical laboratories and workshops. You can put drying cabinets, baths and other heating devices on it. NV-1200 LNn: Stainless steel. Stainless steel is well suited for biological or medical laboratories, but it is not recommended for use in chemical laboratories. It has limited resistance to short-term exposure to concentrated mineral acids and alkalis and is destroyed by prolonged exposure to concentrated acids. NV-1200 LDl: Polypropylene. A specialized solution for chemical laboratories working with inorganic solvents. Advantages of NV-1200 Ln tables A budget solution for laboratories that value the reliability and durability of furniture; Suitable for small rooms; Heating plates or baths can be placed on the granite surface resistant to high temperatures; It is convenient to work while sitting: the height of the work surface from the floor is 75 cm, this is the height of an ordinary office desk. Application of tables NV-1200 Ln 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.
