The optimum working volume is between 0.25 - 1.00 mL.
Top stirring is used to avoid attrition of the crystals. Additionally top stirring can be used for more efficient mixing of thick/jelly like slurries.
The solubility curve has been described as a "roadmap for crystallization".
It is essentially a diagram of the solubility of the solute species in the crystallization solvent over the temperature range within which crystallization will occur.
The advised stirring speed is between 700 – 1000 rpm.
The Peak Wavelength is red 645 nm.
