NARRATIVE
Image shows overall bath with cylinder being added.
 Changes in temperature affect the viscosity of water, and this affects the settling rates of particles in suspension. Therefore, an analyst must maintain a constant known temperature to obtain accurate results during a pipette analysis. The analyst may also find it advantageous to accelerate a pipette analysis by elevating the temperature of the suspension. The most practical way to control the temperature of the suspension during pipette analysis is with a constant temperature bath.
