Antistatic HDPE Coated Centrifuge Machine
This Antistatic HDPE Coated Centrifuge is economical alternative for antistatic HALAR coated centrifuge for some of the chemicals. Maximum continuous use temperature of this centrifuge is 60°C & its electrical resistance is in the range of 10e 6 to 10e 10 ohms. It is far superior to rubber lined centrifuge as life of HDPE is better than rubber & you cannot get anti-static property in rubber lining.
This centrifuge can be used for Aquatic organic & inorganic acids, Alkali, salts as well as large number of organic solvent. This cannot be used for strong oxidising agents, aromatic hydro carbons, halogenated-aliphatic hydrocarbons etc.
Antistatic HDPE coated centrifuge is an alternative between rubber lined centrifuge & antistatic HALAR coated centrifuge with respect to property and economics.
Lining: 1 mm thick Antistatic HDPE coating in black colour.
Normal HDPE coated centrifuge is also available in natural colour.
