Inquire product

The most affordable option in the range of centrifuges for oil laboratories that, due to regulations, do not need heating. It has the same accessories as the heated models, all of them are especially designed for working with oily substances as well as the reagents used in regulations applicable with oil.

Effective, quick, versatile, allowing you to work with 6” and 8” conical profile tubes, pear type tubes and “finger” type tubes for small volumes. It has a pre-installation for incorporating a gas release system at any time during the life of the equipment.
