For the description of ocean currents accurate measurements of the density of sea water are of great importance. For this purpose, measuring instruments are needed which reach a small uncertainty. To ...

Using the large synchrotron radiation facility SPring-8 in Japan, a collaboration of researchers from Kumamoto University, the University of Tokyo, and others from Japan and France have precisely ...

In most applications, level measurements need to be quantified and sent electronically to an automation system, which requires some type of instrument. Sorting through the instrument selection process ...

Q. This is a U.S. Customs hydrometer for spirits (temperatures 0 to 60 degrees Fahrenheit) with original box. I believe it was used in the bootlegging days. It has been in my family since before I was ...

Milk is a very complex liquid that is composed of an expansive diversity of different molecular species. Being the product of mammary glands, milk is the primary food source for neonatal mammals. Even ...

The authors consider several common techniques for verifying the accuracy of liquid-handling equipment and offer guidance for finding the appropriate technique for a given instrument. High-quality, ...

Scientists have measured the density of liquid iron -- the main component of rocky planet cores -- under conditions similar to Earth's liquid core: 1,000,000 atmospheres and 4,000 degrees Celsius.
