Density Gradient Column Apparatus QualiDG-1505 Features

• Utilizes a high-precision microcontroller for temperature regulation, with integrated heating and cooling systems. The stirring mechanism features an external drive with internal spray stirring, ensuring uniform temperature control within ±0.1°C while minimizing bath vibration.
• The bath chamber is constructed from high-transparency resin, offering excellent thermal insulation, clarity, and resistance to vibration.
• Compared to immersion and float-sink methods, the density gradient technique delivers superior accuracy, ease of use, and a broader measurement range.

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.
