An improved density gradient system for forensic science soil studies.
The construction and use of the apparatus required for an improved density gradient system is described. The system is a combination of existing procedures, resultin in a system more suited for forensic science soil studies. The advantages consist of rapid, simultaneous filling of several tubes with identical density gradients and of the capability to remove individual fractions from the tubes for further study. Disadvantages are that an extra quantity of liquids is required and only a preset number of tubes can be filled at one time.
