Density Gradient Column Apparatus QualiDG-1505
QualiDG-1505 Density Gradient Column Apparatus is engineered for highly accurate density determination of solid plastics. It also enables rapid comparison of slight density variations among similar materials.

Applications
- Accurate density analysis of high molecular weight substances
- Density testing for both natural and synthetic fibers
- Evaluation of resin-based materials
- Quality control through precise density measurement
Principle
A glass test tube is filled with two fully miscible solutions, creating a gradient with lower density at the top and higher density at the bottom in a linear progression. A precisely calibrated glass float with a known density is introduced into the column. The float remains suspended at the point where the solution's density matches its own.
