Laboratory industrial gas supply and technology
Variables usually exist in the experiment itself, not in the experimental material. With the purity and integrity of Praxair products, you can greatly increase the accuracy of your experiments. We customize high-purity analytical instrument gases, reagent gases, and mixed gases for your laboratory according to your requirements. However, our laboratory services have not stopped here, and there are various other services besides gas supply. We offer a range of cryogenic storage, gas handling, distribution and storage equipment to help you work safely and efficiently. Your satisfaction is the purpose of Praxair.
Laboratory industry industrial gas, specialty gas, packaging gas and analytical gas
Liquid nitrogen plays a very important role in the freezing and preservation of many biological materials such as cord blood, bone marrow, semen, cell lines, and heart valves. Liquid nitrogen can also be used in various experimental equipment such as cold traps, gas adsorption systems, and nuclear magnetic resonance and nuclear magnetic resonance imaging instruments. Gaseous nitrogen is commonly used for inerting, purging, drying, and packaging operations, and can be used as a carrier gas, diluent gas, or atomizing gas for various analytical instruments.
Oxygen is important for the growth of many bacterial, animal, and plant cells and can be used in incubators and bioreactors to achieve optimal cell growth. .
Carbon dioxide gas is used as an important metabolite or reagent in incubators and bioreactors to adjust the pH value to promote the growth of bacteria, animals and plant cells.
Gaseous helium is the most commonly used carrier gas in gas chromatography. Due to its extremely low boiling point (approximately -269 ° C), liquid nitrogen is used to cool NMR and MRI magnets to a certain temperature point. At this time, the resistance almost disappears and the magnet begins to have superconductivity.
From pharmaceutical experimental applications to DNA research-grade genetic engineering, Praxair ltraIce ™ premium dry ice is essential for the experiment, retention, storage, and transportation of biological samples.
Argon is the main gas in the production of plasma energy. It is used for atomization or ionization of samples in analytical instruments such as atomic emission, atomic absorption, and mass spectrometers.
Hydrogen can be used as a carrier or combustion gas for a variety of analytical applications such as gas chromatography, atomic emission spectroscopy, and atomic absorption spectroscopy.
Laboratory equipment, equipment, supplies and products
Praxair supplies a full range of laboratory gas handling, transportation, storage and safety equipment to help you use our gases more safely and efficiently.
The gas generator
The gas generator can easily produce pure gas, which has significant benefits compared to other products. From hydrogen and nitrogen to zero order air and oxygen, we can help you choose the right gas generation system.
Cryogenic storage equipment
Biological materials can be stored in a variety of ways, of which cryogenic storage can minimize the deterioration of materials and is one of the few preservation methods. Therefore, we cooperate with the world's leading manufacturers of vacuum insulation products and cryogenic systems to provide you with first-class cryogenic storage equipment and overall solutions to ensure that biological materials are properly maintained.
Laboratory industrial services
Praxair not only supplies specialty gases and products to the laboratory, but also works with you to optimize the entire process. From consulting to implementation and practical use, Praxair provides you with a complete set of industrial services to assist in managing gas supply and protecting machines to increase production efficiency.
