Laboratory

What is ASTM Type I, II, and III distilled water? Learn about the differences in purity, conductivity, resistivity, and applications of each grade of water used in laboratories, testing, research, and production.

A guide to accurately converting RPM to RCF. Learn the difference between RPM and RCF, the calculation formulas, practical examples, and why you shouldn't rely solely on RPM when using a centrifuge

When reviewing the specifications of a laboratory circulating bath, two performance parameters frequently appear: Stability and Uniformity. Although both are related to temperature control, they describe two fundamentally different characteristics of the equipment.

Air bubbles that form during stirring not only affect mixing efficiency but can also skew analytical results in some laboratory applications. Learn about the causes and effective ways to minimize them

Circulating baths are widely used in chemical, biological, pharmaceutical, material research, and calibration laboratories. Their function extends beyond heating; they are designed to maintain a stable temperature throughout the entire working area. When temperature uniformity deteriorates, samples placed in different locations within the bath may be exposed to different thermal conditions, affecting the reliability of test results.

If the magnetic stir bar rotates weakly, easily swings away, or no longer creates the same swirling motion as before, has it lost its magnetism? Find out the causes, how to check, and the appropriate solutions.

The performance of a high-temperature circulating bath depends on more than just heating power and controller accuracy. The heat transfer fluid plays a critical role in determining heat transfer efficiency, temperature stability, and the overall reliability of the system.

When selecting a laboratory furnace or heat-treatment furnace, users often focus mainly on the maximum operating temperature. However, one emerging thermal technology trend is the rapid-firing furnace. This type of furnace is specifically designed to achieve extremely fast heating rates, significantly reducing both heat-up time and the overall firing cycle.

Many water treatment systems, after a period of use, begin to show signs of RO membrane degradation faster than expected, stainless steel pipes becoming tarnished, or valve assemblies showing slight corrosion, even though the incoming water appears quite clean.

In industrial pressure measurement and calibration systems, the higher the pressure level, the more stringent the requirements for stability and accuracy become. Even a small deviation can affect the verification results, especially in fields such as oil and gas, industrial hydraulics, energy, or advanced pressure sensor calibration.
