optical quartz glass

A quartz material / glass-encased, spiral-shaped, electrical heating coil with a large surface, which is mounted in a quartz material reflector shell with a handle, allows liquids to be heated indirectly by infrared radiation. This is used for the fast, economical evaporation or concentration of liquids. Due to this principle, only the surface of the liquid is heated very strongly, as the thermal radiation is absorbed even after shallow penetration, thus enabling gentle, uniform evaporation.In contrast to boiling evaporation, there is no loss of substance due to splashes from a moving boiling surface. Since surface evaporators are made exclusively from the material fused quartz / glass, it is possible to use the advantages of the material, such as good IR permeability, heat and heat change resistance, lowest electrical conductivity, exceptionally high chemical purity and resistance as a material. It complies with EC Directive 89/336 / EEC and EC Directive 73/23 / EEC.

Immersion heater for laboratory and electroplating technology Advantages: Maximum energy utilization through infrared radiation - the cladding tube is infrared permeable; through heat conduction - the cladding tube made of quartz glass enables particularly good heat transfer. Temperature resistance Since quartz glass has practically no thermal expansion, such immersion heaters are particularly resistant to heat changes. Acid resistance Quartz glass immersion heaters are almost resistant to acids except phosphoric acid above 300 ° C and hydrofluoric acid. They are therefore particularly suitable for the direct heating of chemicals in the laboratory and electroplating technology. electric security The cladding tube made of quartz glass is an excellent electrical insulator - safe contact protection; optimal electrical safety through earthing of the interior. In compliance with EC Directive 89/336 / EEC and EC Directive 73/23 / EEC.

Glass surfaces are extremely smooth and meet high hygiene requirements. They are more resistant than plastic and have a high temperature, as well as high chemical resistance. In addition, glass decors ensure a design-oriented and high-quality finish. We offer molded glass parts for a variety of industrial and electronic applications. These include, for example, cover glasses and decor glasses for electronic products and protective glasses for displays. The glasses are usually made of float glass or white glass and thermally hardened ESG glass. The strength is from 0.55 to 19.0mm. For applications in the field of display protection, we also offer ultra-thin chemically hardened front glasses (0.3 – 8.0 mm). Other types of glass include borosilicate glass, quartz glass, magic mirror glass and touch panel glass.

Not only will the Philip Zepter Globhora show the time in other parts of the world by using the pushers to switch from one city to the other, but it will also stay in that time zone by a simple activation of the crown. Excitingly, GlobHora is set with a perpetual calendar that will have to be reset in the year 2099. This is incontestably a major benefit at such a level of creative complexity. Moreover, our GMT specifies if it is day or night with the AM/PM display. Presentation THE TRAVELER’S BEST COMPANION GlobHora is the GMT of Zepter’s watch collection. GMT comes from Greenwich Mean Time which was established in 1884 as a global time standard that governs the international timing and time gaps between countries. For time devices, GMT means that a watch is able to indicate at least a second time zone. GlobHora, though, has the remarkable capacity to indicate 24 different time zones. Key Features: - Sapphire glass quartz movement;

The distinctiveness of these capillaries is their very thin wall-thickness in relation to their diameter. The extremely thin walls lead to the special feature of these capillaries to be deformed easily. Additional features linked to the thin wall-thickness are minimal optical distortion as well as very low absorption for a wide range of radiation. This feature is used e.g. for the construction of optical measuring cells.

We manufacture reagent and centrifuge tubes in standard sizes and also with special dimensions and versions from soda glass, borosilicate glass, neutral glass, and quartz glass – optionally with or without flanged rim. All our tubes have a flame burnished rim and can be supplied with a rounded, flat or pointed conical bottom. We are able to process tubes with diameters up to 40 mm, and lengths up to about 500 mm – also thick-walled tubes. Special reagent micro tubes We are able to manufacture reagent micro tubes with rounded bottoms, i.e. with very small dimensions. For example, soda glass tubes with rounded bottom, flame burnished rim, 3 mm diameter, and a length of 20 mm. Test tubes with notch for thermal processes These special test tubes were developed to enable ventilation of the tube’s interior during a thermal process. The notch prevents complete closure and thus an over pressure.

We offer a wide range of tubes for the automatic or manual determination of the melting or boiling points of liquids and solids. For this, the samples are heated slowly in the test tube until they reach their melting or boiling point.
