The Sartorius M3P is a high-precision, electronic microbalance designed for accurately weighing small samples in laboratory settings. A protective glass or metal enclosure that reduces air currents ...

There are few experimental techniques that allow the study of force on biological molecules. Among them, optical or magnetic tweezers and atomic force microscopes (AFMs) have provided much insight ...

The quartz crystal microbalance (QCM) is a precise mass sensor that exploits the piezoelectric effect in quartz crystals to detect minute mass variations on its surface. At its core, the QCM operates ...
