Technical Solvents. 
Often important for the modern laboratory is a source of high
quality technicla solvents. ECP recognise this and are able to supply high
quality technical solvents for the laboratory and as a first step in
high purity extraction and refinement of
biological and organic
compounds. From our specially sourced extraction grade hexane with
aromatics/benzene of less than 0.02%, through to absolute ethanol. See our range
below and then check the price and availability by entering the code into our
search facility.
