INDUSTRIAL GAS SUPPLY & TECHNOLOGY FOR LABORATORIES
Pure control
Variables belong in your experiments, not your lab materials. At Praxair, you can depend on the purity and integrity of our products to help you conduct the most accurate experiments possible. We’ll supply your lab with a full line of high-purity analytical instrumentation gases, reagent gases, and gas mixtures, customized to your requirements. And we don’t stop there. Our laboratory services go far beyond gas supply. We offer a full line of cryopreservation and gas handling, distribution and storage equipment to help you work safely and productively. Because at Praxair, we don’t experiment with your satisfaction.

INDUSTRIAL, SPECIALTY, PACKAGED & ANALYTICAL GASES FOR LABORATORIES
Nitrogen
Liquid nitrogen is essential for freezing and preserving many biological materials, including cord blood, bone marrow, sperm, cell lines and heart valves. Liquid nitrogen is also used with a variety of lab equipment, such as cold traps, gas adsorption systems, and NMR and MRI instruments. Gaseous nitrogen is commonly applied for inerting, stripping, drying and packaging and used as a carrier, diluent, or nebulization gas in various analytical instruments.
Oxygen
Oxygen is critical for many bacteria, animal, and plant cell growth applications and can be supplied to incubators and bioreactors to achieve optimal cell growth.
Carbon Dioxide
Gaseous carbon dioxide is used in incubators and bioreactors as an essential metabolite or agent for pH regulation to promote bacteria, animal and plant cell growth.
Helium
Gaseous helium is the most common carrier gas in gas chromatography. Because of its exceptionally low boiling point (approximately -269°C), liquid helium is used to cool NMR and MRI magnets to the point where their electrical resistance is virtually non-existent and they become superconducting.
Argon
Argon is the primary gas used to produce plasma energy sources for sample atomization or ionization in such analytical instruments as atomic emission, atomic absorption, and mass spectrometers.
Hydrogen
Hydrogen acts as a carrier gas or combustion gas in multiple analytical applications, including gas chromatography, atomic emission spectroscopy, and atomic absorption spectroscopy.
LABORATORY APPARATUS, EQUIPMENT, SUPPLIES AND PRODUCTS
Cryopreservation equipment
While biological materials can be preserved in many ways, low-temperature storage is one of the few preservation methods that minimizes changes in the material. So, we teamed up with the world’s leading manufacturers of vacuum insulated products and cryogenic systems to provide you top notch cryopreservation equipment and turnkey solutions that ensure the maintenance of your biological materials.
INDUSTRIAL SERVICES FOR LABORATORIES
We do more than provide specialty gases and products to laboratories. We will help you optimize your process. From consultation to implementation and use, we offer a range of services that help you monitor and manage your gas supply so you can focus on being more productive.
