Titration with a Bottletop Burette

Simplify Titration with a Bottletop Burette Titration is a common laboratory exercise employed to determine the unknown concentration of a substance called the analyte (a.k.a. titrand or what you are analyzing for) in a solution.   This is accomplished by carefully and precisely metering a reagent (a.k.a. titrant) into the solution until a reaction occurs.  The…

A Guide to Homogenizer Components

When selecting a laboratory-grade homogenizer research and process development scientists generally focus on the objective of the emulsifying exercise and the physical characteristics of the material being studied.  This information will guide the selection of the rotor and stator configuration. To get the terminology straight in this post we call the rotor (attached to the…
