Density Gradient Column Floats

We produce calibrated glass floats for use in density gradient columns within the density range 650-2000 kg/m³ (0.65-2.00 g/ml) at 23°C. Each float has a unique identification number and is calibrated under our ISO 17025 accreditation. Floats are supplied with UKAS calibration certificates. We can also calibrate customers’ own floats.

Alcofloats

The Alcofloat Spirit Test Kit was developed in conjunction with a major pub and restaurant chain and a leading Trading Standards office. The kit is used to detect the ‘watering down’ of spirits. The kit is supplied with a UKAS calibration certificate, so that the results are often admissible in court or in industrial tribunals.
