Annalytical viscommetry in biodiesel
Fuel-grade biodiesel must be produced to strict industry specifications (ASTM D6751) in order to ensure proper performance of the fuel.
Fuel-grade biodiesel must be produced to strict industry specifications (ASTM D6751) in order to ensure proper performance of the fuel As listed in Euopean Standard EN14214, Biodiesel manufacturers are required to determine viscosity at 40 degrees Celcius as per the test method EN ISO 3104

Determining water levels in lubricating oils
It is impoirtant to determine the presence of water in machinery lubricating oils, which is why Metrohm is offering its 831 KF Coulometer to give reliable results over a long period.
Biodiesel is the name of a clean burning alternative fuel, produced from domestic, renewable resources.
Biodiesel contains no petroleum, but it can be blended at any level with petroleum diesel to create a biodiesel blend.
It can be used in compression-ignition (diesel) engines with little or no modifications.

Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulphur and aromatics.
Biodiesel is made through a chemical process called transesterification whereby the glycerin is separated from the fat or vegetable oil.
The process leaves behind two products -- methyl esters (the chemical name for biodiesel) and glycerin (a valuable byproduct usually sold to be used in soaps and other products).
The use of alternative fuels from renewable vegetable sources has become increasingly widespread in recent years, as the life cycle of biogenic fuels is neutral with respect to CO2 release.
The carbon dioxide released has already been assimilated from the atmosphere during plant growth.
In contrast to fossil fuels, biogenic fuels neither contribute to the accumulation of CO2 in the atmosphere nor to global warming.
In addition, alternative fuels are biodegradable and thus less environmentally harmful.
Viscosity Measurement Automated viscosity measurement in the BIODIESEL field requires a robust, resistant, reliable instrument which is simple to use and does not require highly skilled staff in order to produce accurate results.
The versatility of Fungilab viscometers makes them ideal tools for all types of users in the lab as well as the demanding conditions in the production area.
There are three viscometers in the Fungilab range, all available in variants for low, regular and high viscosity applications, in each case the "R" variants (regular) cover over 80% of applications VISCO BASIC Plus ~The entry level instrument, low cost - but with excellent price / performance ratio.
Key features include:- Extremely simple to operate and produce fast, accurate results.
Relative and absolute viscosity determinations.
Direct result readout on an illuminated liquid crystal display.
Built-in auto test feature with acoustic and visual alarms in case any malfunction.
Simple, user initiated calibration of viscometer.
