Most pressure gauges, like those on scuba tanks, are calibrated to read zero at atmospheric pressure. Readings from such gauges are called the gauge pressure, which is the pressure relative to atmospheric pressure. When the pressure inside the tank exceeds atmospheric pressure, the gauge reports a positive value. Some gauges are designed to measure negative pressure. For example, many physics experiments must take place in a vacuum chamber, a rigid chamber from which some of the air is pumped...

The analytical ultracentrifuge (AUC) sample cell holds sample and reference buffer and during experiments and is exposed to high vacuum and rotor speeds up to 60,000 rpm. This video will demonstrate the rigorous attention to detail necessary for assembly, loading and alignment of this very important component of an AUC experiment.

The laser heated diamond anvil cell combined with synchrotron micro-diffraction techniques allows researchers to explore the nature and properties of new phases of matter at extreme pressure and temperature (PT) conditions. Heterogeneous samples can be characterized in situ under high pressure by 2D mapping and combined powder, single-crystal and multigrain diffraction approaches.

Here we describe how to build a robust spring-transport mechanism for a spinning rotor gauge. This device securely immobilizes the rotor and keeps it under vacuum during transportation. We also describe packaging that minimizes the risk of damage during transport. Tests show our design works for typical shocks during transport.

Robert M Rioux, Pennsylvania State University, University Park, PA The use of gases in a synthetic chemistry laboratory is essential for carrying out a variety of highly facile and atom economical transformations. Reactions such as hydrogenation, oxidation, and amination require the use of gases like hydrogen, oxygen, and ammonia. Due to the poor solubility of these gases in typical reactant solutions, high pressures are necessary to achieve a meaningful reaction rate. Not only are these gases...
FAQs
In a mechanical assembly, pressure first deforms an elastic sensing element such as a diaphragm or Bourdon tube. That deformation becomes mechanical movement, which a linkage transfers to a pointer moving across a calibrated scale. The readout therefore reflects the element’s response to pressure, allowing an operator to observe changes in a monitored fluid or gas system.
Mechanical and electronic designs differ mainly in how sensing movement becomes readable information. Mechanical versions transmit deformation through a linkage to a pointer and scale, whereas electronic versions convert the deformation into an electrical signal. This distinction affects the form of the output used to monitor pressure in laboratory equipment and bioprocess systems.
The housing and process connection support the integration of the sensing and readout components with the monitored system. The housing forms part of the assembled instrument, while the process connection links it to the relevant fluid or gas pathway. Pressure monitoring therefore depends on both the sensing element and how the assembly is incorporated into operation.
Selection and installation should be tied to the operation being monitored, whether it is filtration, pumping, fluid transfer, or a bioreactor. A properly selected and installed assembly provides pressure information at that process point. This connection between application and setup helps maintain controlled experimental conditions and supports safer, more reproducible laboratory or bioprocess work.
Biological laboratories and bioprocess operations can use these assemblies in filtration systems, pumps, fluid-transfer lines, and bioreactors. In each setting, the gauge monitors pressure within equipment or a process pathway. The resulting information helps operators maintain the intended operating conditions while observing pressure-related changes during fluid or gas handling.
Pressure monitoring supports several practical outcomes: it helps control experimental conditions, protect equipment, and improve reproducibility. It also contributes to operational safety by making pressure conditions observable in systems such as pumps, filtration equipment, fluid-transfer lines, and bioreactors. Reliable monitoring is therefore relevant to both routine biological experiments and larger-scale bioprocess work.
