Befort VIS objectives are colorcorrected for VIS use and are routinely equipped with VISAR coating. The UV objectives are made of quartz glass or CaFl2 and optimized for λ = 185 nm

Economic acquisition, powerful performance values and simple handling – these characteristics are combined in a robust metal construction of the air cleaner TAC 1500 S that is suitable for use on construction sites. Its Monoventic regulator enables you to steplessly adjust the air volume precisely to your actual needs, and the flexible filter system allows for the use of variable filter combinations for every construction site situation. With the TAC 1500 S you can reliably filter coarse and fine dust or spray paint mist as well as concrete dust, fine sanding or plaster dust and highly dangerous quartz dusts or asbestos fibres. The filter frame can be flexibly equipped with one or two filter elements, for example a G4 filter or an additional F7 filter, so that in combination with the HEPA filter a two- or three-stage air purification process in accordance with dust class H can be achieved.

Befort develops and manufactures laser optics for a wide range of applications since more than 20 years. Befort offerings range from a simple AR coated protective glass with a high laser damage threshold to a complex focus readjustment unit for ultrashort pulse lasers (Zoombox). Our laser optics are made of high quality Schottglass or quartz glass. Befort coats the optics precisely for their wave length. The coating exhibits a particular high laser damage threshold (LDT). We develop and manufacture for you Laser mirrors (metallic or dielectric) Laser filters Laser optics Telecentric laser optics Ultrashort pulse laser optics

SIMPLE OPERATION FOR MANY APPLICATIONS STM-2XM is a two channel rate/thickness monitor that combines high accuracy with flexible programming and easy operation at an affordable price. STM-2XM is equipped with five operation modes to accommodate processes from simple to complex. For example, use simple mode to monitor just one single sensor for the simplest process or use alloy mode for codeposition monitoring. Independent mode allows STM-2XM to function as two completely separate monitors. Two sensor inputs allow for the use of two single or one dual quartz crystal sensor. 10 measurements are taken per second while achieving a resolution of 0.037 Å per measurement (density of 1). FEATURE PACKED STM-2XM has eight programmable digital inputs, eight programmable digital outputs, and four analog outputs allowing for a level of integration usually reserved for more expensive instruments. Programmable features include shutter delay, time/power monitoring, and rate sampling. Use...

For removing dust prior to maintenance and repair work, e.g. on magnetic plates, reading heads, audio-visual magnetic tape recording and playback heads, phonograph pick-ups, record turntables or phonograph records For cleaning vacuum sealing surfaces, sealing rings, high-voltage insulators, sample containers etc. For vacuum systems and device groups under clean-room conditions for semiconductor production Cleaning of opto-electronic reading units for bank checks and contactless cleaning of optical devices For maintenance of automated teller machines, quartz clocks or display panels For dedusting precision mechanical parts and assemblies in office machines, copiers, fax machines etc. Advantages and benefits Excellently suited for dedusting, blowing out and blowing off dust and liquids of all kinds Dry, oil-free compressed gas leaves behind no residues Replacement for ultrapure compressed air

Our standard glass beads are simple products in sizes from 1 mm upwards, and with a relatively wide range of tolerances. They are usually made of soda glass, borosilicate glass or lead glass, whereby the surfaces can be matt or polished. On request, we can manufacture borosilicate or quartz glass beads with dimensions according to your specifications. Standard glass beads

Our high-precision glass beads are usually made of soda glass or borosilicate glass, but on request we can also supply quartz glass, sapphire glass or optical glasses. The standard tolerance is ± 0,02 mm. Without surcharge, the surfaces can be supplied matt or polished. You need even higher precision? No problem: We can also supply customized glass beads with tolerances of ± 0,01 and ± 0,005 mm. Precision glass beads

Glass beads are a low-cost alternative for Raschig rings. They have less surface area than the rings, and therefore a reduced separation capacity, but they are perfectly adequate for many applications. Our glass spheres can also be supplied with a matt surface. Various types of glass are possible for our glass beads: Soda glass Borosilicate glass 3.3 Quartz glass On request, we can manufacture borosilicate or quartz glass beads with dimensions according to your specifications.

Boiling rods Boiling rods are ideally suited to prevent superheating during boiling or distillation in glass beakers or Erlenmeyer flasks. They are made of high-grade soda glass, are reusable, and excellently suited for many applications. Stirring rods Used for mixing and homogenizing mixtures of chemicals and samples. They are also ideal for stirring hot or boiling substances. They are made of high-grade soda glass, are reusable, and excellently suited for many applications. For special applications, they are also available in borosilicate or quartz glass.

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 develop and manufacture special seals for power stations, for the chemical and petrochemical industries, for machinery and pipeline construction. In other words, seals that provide the greatest possible reliability even under extreme operating conditions (pressure, heat, cold, aggressive media) – at temperatures from -200 to +1.000 °C. Product Range: - DVGW tested, see separate brochure - Punched, cut seals - Plates, foils - Semi-finished items - Form articles Benefits: - Highest chemical resistance - Insoluble and does not swell in organic or anorganic solvents - Resistant to the weather - Temperature range -190 to +250 °C - Highly anti-adhesive, does not stick - Resistant to hydrolysis Common fillers: - Quartz - Glass - Carbon / Graphite - Bronze - or without filters Fillers reduce the cold flow, lead to higher resistance to temperature and media, improve thermal conductivity and increase resistance to abrasion and pressure levels.
