Ordering Liquid Density Standards
Liquid Density Standards are priced at £70GBP per ~10ml ampoule. Most liquids are usually available from stock.
How to Order Liquid Density Standards
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.
|Liquid||Density at 20°C (kg/m3)||Temperature Range (°C)||Uncertainty (kg/m3)|
|Lube oil Largo ~8 mPa·s @40°C||824||10-50||±0.010|
|Lube oil Largo ~32 mPa·s @40°C||867||10-50||±0.010|
|Lube oil Largo ~22 mPa·s @ 40°C||897||15-50||±0.010|
|Ethanol in water ~40% ABV||948||20||±0.030|
|Ethanol in water ~ 9% ABV||985||20||±0.010|
|Water (multi temperature)||998||10-50||±0.010|
|Dextrose in water ~10% w/w||1037||20||±0.010|
|Dimethylphthalate ~17mPa·s @20°C||1191||15-25||±0.010|
|Sodium bromide in water ~27% w/w||1249||15-25||±0.025|
|Caesium chloride ~48% w/w||1553||15-25||±0.020|
Remember! Your density meter is only as good as its last calibration.
Within the UK, the standard charge is £17.50GBP. Carriage costs for deliveries outside the UK will depend upon the destination and the weight of the shipment.
We are able to accomodate customers who wish to use their own carrier, however an administration fee may be charged. Any consignment going outside the UK which contains 2,2,4 trimethylpentane, Ethanol ~40% or Tetrachloroethylene must travel by our carrier, since these are classified as dangerous goods for air travel and few carriers will accept them.
