Gravimetric production
Blending to DIN ISO 6142-2 using high-precision balances — the most accurate method for reproducible concentrations.
Our core business
Gases
From a single 50-litre nitrogen cylinder for the workshop to a complete supply installation — advice and delivery from one source.
Our gases at a glance
We produce, blend and deliver gases for industry, medicine, laboratories, food processing and heating. Customer-specific mixtures are made in our own calibration-gas laboratory.
Industrial gases
Oxygen, nitrogen, argon, acetylene, hydrogen and gas mixtures — including our own calibration-laboratory blends.
Medical gases
Medical oxygen (KUFVITA 100% V/V), anaesthetic gases, high-purity laboratory gases, liquid helium.
Food-grade gases
CO₂, nitrogen and KUFBIO mixtures for carbonation, modified-atmosphere packaging and freezing.
Calibration and laboratory gases
Purities up to 6.0, calibration gases from ppm to per-cent level, gravimetric blending to DIN ISO 6142-2.
LPG (propane)
Propane tanks at your premises, filled by our own fleet, tank inspections carried out on site.
Quality and safety
Safety data sheets, information on the German Major Accidents Ordinance and safe handling of gases.
Industrial gases
Industrial gases determine quality and cost in many manufacturing processes. We produce and deliver the classic industrial gases and blend customer-specific mixtures in our own calibration-gas laboratory.
Pure gases
Oxygen (O₂), nitrogen (N₂), argon (Ar), acetylene (C₂H₂), hydrogen (H₂), carbon dioxide (CO₂), helium (He) and compressed air — in cylinders, bundles, as cryogenic liquid and in dry-ice form.
Gas mixtures
- Argon/CO₂ and argon/CO₂/O₂ for MAG welding
- Forming gas (hydrogen/nitrogen) for root protection
- Customer-specific calibration and mixed gases from our own production
Typical applications
- Laser technology
- Welding
- Cutting
- Brazing and soldering
- Heat treatment
- Metallurgy
- Flash freezing
- Environmental, measurement and control technology
Cylinder sizes, contents and valve connections are listed on the German product pages: Technische Gase.
Medical gases
Manufacturing, packaging, delivery and traceability to pharmaceutical quality standards, so that you can concentrate on patient care.
- KUFVITA 100% (V/V) — medical oxygen
- Our own finished medicinal product: manufactured, filled and delivered to pharmaceutical quality standards and traceable throughout.Authorised medicinal product · marketing authorisation no. 75085.00.00, on the market since 2012.
- Anaesthetic gases
- Nitrous oxide (N₂O) in particular — for hospitals, practices and outpatient care, in cylinder sizes to suit.
- Medical CO₂
- Carbon dioxide in medical quality, available in various cylinder sizes.
- High-purity laboratory gases
- For medical and biological research and for analysis in hospital laboratories.
- Liquid helium
- For magnetic resonance imaging and other cryogenic applications.
Where our medical gases are used
- Intensive care
- Hospitals
- Medical practices
- Research institutes
- Home care
- Magnetic resonance imaging
- Preservation of biological material
Food-grade gases
Freezing, chilling, carbonating, packaging — gases extend shelf life and protect quality.
Carbon dioxide (CO₂)
- Carbonation of beverages
- Freezing and chilling of food
- Regulating plant growth in greenhouses
- Available as gas, as liquid (dip-tube cylinder) and as solid dry ice
Nitrogen (N₂)
Protective gas that displaces atmospheric oxygen and so prevents oxidation and microbial spoilage of sensitive foods.
KUFBIO — our own brand
Nitrogen/carbon dioxide mixtures in the three most common ratios, matched to typical applications in catering and beverage filling: 80/20, 70/30 and 60/40 (nitrogen / carbon dioxide).
Calibration and laboratory gases
For laboratory work, measurement technology and R&D we supply purities up to 6.0. On request we produce calibration gases with one or more components in a base gas, from the low ppm range up to per-cent concentrations.
Certificate of analysis
Every calibration gas is delivered with a certificate to DIN ISO 6141.
Multi-stage quality control
Gas chromatography, optical methods, chemiluminescence, moisture measurement and further analytical procedures.
Typical applications
- Calibration of measuring instruments
- Trace gas analysis
- Emission measurement
- Process monitoring
LPG (propane)
Liquefied petroleum gas is a flexible energy source, including where there is no natural gas grid. We deliver, fill and maintain your tank installation from one source.
Clean heating
Clean combustion with low CO₂ and particulate figures compared with heating oil.
Independent of the grid
Ideal wherever no natural gas connection is available — from a rural house to an industrial site.
Our own fleet
We fill with our own road tankers and carry out tank inspections on site.
Typical uses
- Heating in residential buildings
- Process heat in industry and trade
- Agriculture and forestry
- Catering, hotels and events
Around the clock
Autogas (LPG) filling station in Remshalden
Self-service LPG at the oxygen plant, Bahnhofstraße 64. The price of the day is shown on the display at the entrance. Accessible 24/7, including nights, weekends and public holidays; staff are on site during plant hours only.
Quality and safety
We work to DIN EN ISO 9001 and provide safety data sheets for our gases and gas mixtures in their current version. Please keep the relevant data sheet available at the workplace.
Safety data sheets are issued in German. They are collected in the download centre, sorted by pure gases, gas mixtures and physical state.
