High Purity Carrier Gases:

High-Purity Nitrogen, Helium, and Carbon Dioxide:

Weldstar Specialty Gases act as essential calibration standards for analytical instruments.

Researchers use them to fine-tune equipment, ensuring reliable and consistent measurements throughout drug development and manufacturing processes.

Bioprocessing and Cell Culture:

Carbon Dioxide (CO2):

CO2 is crucial for maintaining optimal pH levels in cell culture and fermentation. It enhances cell growth and protein production.

Oxygen (O2):

Oxygen is essential for aerobic cell cultures. It supports cell metabolism and energy production.

Nitrogen (N2):

N is used for sparging and purging bioreactors. It helps remove dissolved oxygen and prevents oxidative stress in sensitive cultures.

Cryo-Preservation and Repositories:

Liquid Nitrogen (LN2):

Liquid Nitrogen is used for cryo-preservation of biological samples, including cells, tissues, and genetic material. It ensures long-term storage at ultra-low temperatures.

Helium (He):

He is used in cryogenic systems for cooling and maintaining low temperatures in sample storage facilities.

Drug Manufacturing and Synthesis:

Hydrogen (H2):

H is involved in various chemical reactions during drug synthesis. It serves as a reducing agent and participates in hydrogenation processes.

Nitrogen (N2):

N is used for blanketing and inerting during drug manufacturing. It prevents oxidation and ensures product stability.

Argon (Ar):

Ar is employed for shielding during welding and as a carrier gas in gas chromatography. It maintains the purity of drug compounds.
