Abstract
An apparatus and method for mixing a liquefied sample and weighing the sample are provided. The method includes providing a balance for weighing the sample, removably mounting a magnetic mixer having a drive mechanism on the balance, mounting a holder on the magnetic mixer, placing a sample container containing the liquefied sample and a magnet capable of clockwise and counterclockwise rotation under influence of the drive means on the holder, operating the drive mechanism and rotating the magnet thereby mixing the liquefied sample, and weighing the liquefied sample. The power source of an air-powered balance mixer is connected such that any external noise is isolated when the mixer is not in use. Air flow from a pressurized air source is channeled through a nozzle and collected by the intake port of the air mixer. The nozzle drives the mixer without actually touching the mixer or the balance. An air gap exists between the mixer and air nozzle so that when the mixer is turned off the mixer has no effect on the weighing results.
