What is the purpose of using the rotary evaporator? - Lab ...

A rotary evaporator (or rotavap/rotovap) is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation.. The purpose of distillation is to separate a given mixture into its components based on their respective volatilities, through the process of evaporation and condensation (liquid-gas-liquid).

Even though the technology of the SSB-LCG is simple in principle: A special muffle is installed downstream from a swirl burner (SSB) in which the supercritically swirled lean gas flame burns stably. This process developed by SAACKE works without a support fuel and achieves astonishingly low NOx emission values less than 20 mg/m .

Gravimetric analysis - Wikipedia

Gravimetric analysis - Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as …

Gravimetric Analysis - Definition, Types and Steps

Gravimetric analysis is a method of a quantitative assessment of laboratory techniques based mostly on the dimension of an analyte's mass. One example of a gravimetric evaluation technique may be used to decide the quantity of an ion in an answer by way of dissolving a regarded quantity of a compound containing the ion in a solvent to break up the ion from its compound.
