What is the Kjeldahl method? The Kjeldahl method (the industry standard test used to routinely measure the crude protein content of foods) measures the total nitrogen content of a food, which is then used to estimate the crude protein content by applying a conversion factor to the result. The Kjeldahl method is widely used internationally and is still the [...]

A particle size analyzer is an analytical instrument that measures, visualizes and reports a particle size distribution for a given particle or droplet population. Particle size analyzers play an important role during process development and quality control of particle systems in order to develop efficient processes and achieve high final product quality. Traditionally, sampling and offline particle size analyzers [...]

A fume hood is typically a large piece of equipment enclosing five sides of a work area, the bottom of which is most commonly located at a standing work height. Two main types exist, ducted and recirculating (ductless). The principle is the same for both types: air is drawn in from the front (open) side of the cabinet, and [...]

From reliance on single-use plastic products to the use of high-energy-consumption equipment like -80°C freezers and fume hoods, modern clinical labs leave a surprisingly large carbon footprint. Indeed, a laboratory typically consumes between four and five times more energy per square foot than a commercial space. This scenario can be a wake-up call for clinical labs to adopt more sustainable [...]

Laboratory shakers, also known as mixers, are laboratory products used in chemistry and biology to mix liquids and prepare solutions and suspensions. This equipment creates a movement between liquids or between liquids and solids to achieve processes of mixing, suspension, dispersion, homogenization, heat transfer, etc. At present, stirring systems (agitators) are used in all laboratories, be they chemistry, or [...]

Spectrophotometer Overview： After some groups in the molecule absorb visible radiation, the transition of electronic energy level occurs, resulting in the absorption spectrum. Since various substances have different molecules, atoms and different molecular space structures, the energy of absorbing light is different, so each substance has its own unique and fixed absorption spectrum curve, which can be determined according [...]

1. Due to the large heat of the liquid nitrogen tank and the long heat equalization time when sub-filling liquid nitrogen, a small amount of liquid nitrogen medium can be pre-cooled (about 60L), and then slowly filled (so that it is not easy to form ice blockage) ). 2. In order to avoid the consumption of liquid nitrogen filling [...]
