Main Types of Lubricants for Bioreactors and Fermenters

Bioreactors and fermenters operate in highly sensitive environments where contamination prevention, chemical stability, and compliance with food and pharmaceutical regulations are critical. MOLYDUVAL offers a wide range of high-quality lubricants specially designed for these industries, meeting strict international certifications such as NSF H1, Halal, and Kosher.

Food Grade Lubricants (NSF H1)

• Used in places where accidental contact with the product is possible.

• Base: PAO (polyalphaolefins), esters, or silicones.

Examples:

• Molyduval Sekorex Non Tox 150 (chain and gear oil)

• Molyduval Siligra TS 3 (for gears, bearings)

Biodegradable Lubricants

• Used in environmentally friendly processes or where biodegradability is required.

• Based on synthetic esters.

Silicone Lubricants (NSF H1 / Halal / Kosher)

• Used for seals, valves, O-rings, as silicone provides excellent chemical and temperature resistance.

Examples:

• Molyduval Silo D 350 (silicone oil with NSF H1)

High Temperature Lubricants

• Used in bioreactors or fermenters where high temperatures occur (e.g., sterilization), special high-temperature food-grade lubricants are applied.

Examples:

• Molyduval Pegasus UEF 2 (NSF H1)

Certifications to Consider:

• NSF H1 – for incidental food contact

• NSF 3H – for direct food contact

• Halal / Kosher – when producing products for these markets

• FDA compliance – important in the pharmaceutical sector
