Density Gradient Columns

We are the topmost distributor and supplier of Density Gradient Columns in Vadodara, Gujarat, India. the Davenport density measuring columns are designed to measure the density of solid materials, notably plastics, according to BS2782 Part 6 Method 620D, ASTM D1505-68, ISO 1183 and others. It is also a quick comparative test, ideal for discerning density differences between similar materials. A linear liquid density gradient is fitted in a cylindrical glass tube and maintained at 23C to prevent the gradient being disturbed by thermal convection. Temperature control circuits work in conjunction with electric heaters and a simple cooling coil to maintain accuracy. The density gradient obtained is determined by introducing a set (usually nine) of accurately calibrated marker floats whose densities cover the desired range of the column at equal density intervals. The floats provide not only the calibration reference values of the gradient, but also act as a check on the stability of the density gradient.
