The Auto Density Gradient Apparatus from Ray-Ran has become the world’s benchmark for accurate density measurement of small solid specimens using the column method. Offered as a 3 or 6 column version, the built in on-board Microprocessor System accurately calculates the specimen’s density more quickly and more accurately by using the latest linear encoder technology that measures the samples position in the column relative to the calibrated glass marker floats. Once the correct position of the sample is recorded the density is displayed on the LCD screen.
To ensure results accuracy the Density Gradient Apparatus is supplied with digital temperature control to ensure the temperature of each column is at 23°C +/- 0.1°C. For ambient temperatures in excess of 23°C the integrated cooling coil can be used in conjunction with an optional water chiller unit so the correct temperature can be maintained.
