Hi all, first post here, I'm hoping someone can help me with a mixing process I need to do to make a supplement/emulsion (not illegal). My question only relates to the heat and stirring, not any of the substances (question below steps). Below are the steps given: 1. Prepare a water solution containing sugar and warm up to 80-85°C under stirring. 2. In a beaker, weigh the powder and at least one excipient or stabilizer and warm up to 80-85°C under stirring. 3. Pour the solution into the beaker with powder and the excipient under strong stirring and keep at 80-85°C for 5 min under stirring. When the temperature is below 50°C, the formulation becomes transparent. 4. Switch off the heater and keep under moderate stirring until room temperature is reached. 5. Add a preservative (e.g., potassium sorbate, sodium benzoate, citric acid anhydrous). My question is based around the heat and stirring, would this be best done as a manual process with a flame, or is there a device that can alter stirring speeds as well as vary the temperature? I've noticed some magnetic devices that may do this however i'm an absolute rookie so hoping there's someone far more knowledgeable than me here. Thanks legends. Nog
