With the holiday season upon us, it is useful to be able to determine just how much (or how little) spiking the office party punch has received. [Russell Smith] shows how he tried to determine the ...

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 ...

Researchers at the National Institute of Standards and Technology (NIST) have found a way to link measurements made by a device integral to microchip fabrication and other industries directly to the ...

Mettler Toledo has released the XP56 Microbalance, which is designed to tackle a typical problem of development and quality-control labs: With its minimum sample size and simple sample transfer ...

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 ...

Researchers have found a way to link measurements made by a device integral to microchip fabrication and other industries directly to the recently redefined International System of Units (SI, the ...
