Ideally, you should calibrate your density meter using two standards, with densities either side of the range in which you are working. Choose your liquids from the table below.

The UK standard charge is £24.00 and is normally next day delivery. DHL carriage costs for deliveries outside the UK will depend upon the destination and the weight of the shipment.

Any consignment going outside the UK which contains 2,2,4 trimethylpentane, Ethanol ~40%, Jet A-1 or Tetrachloroethylene must travel by our carrier, since these are classified as dangerous goods for air travel and few carriers will accept them.
