The difference between A2 and B2 of the Class 2 biological safety cabinets is that the exhaust airflow of the A2 type safety cabinet is discharged back to the room after high-efficiency filtration, and the exhaust airflow of the B2 type safety cabinet is discharged outdoors after high-efficiency filtration. 1. Since the two types of Class 2 biological safety [...]

Labs invariably have a large variety of biological samples, reagents, and solutions that need to be properly stored, for the short or long-term. However, the optimal storage temperature for a given sample can vary depending on its intended use, suspension buffer, and duration. With limited lab space and operating costs, good storage practices are an invaluable asset to any [...]

A muffle furnace, also known as a retort furnace, is a piece of oven-type equipment that can reach high temperatures. It usually works by putting a high-temperature heating coil in an insulating material. The insulating material effectively acts as a muffle, preventing heat from escaping. How does a muffle furnace work? A Muffle furnace allows rapid high-temperature heating, recovery, [...]

1. According to the principle of sterilization and disinfection, dental instruments are divided into three categories. 2. After the instrument is used, it should be sorted initially, soaked in the maintenance solution, and waited for cleaning. 3. Cleaning personnel wear gloves and masks, use brushes and clean water to clean saliva and pollutants on the surface of the equipment, or [...]

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 [...]

Findings show increased mortality risks in offspring from birth to young adulthood A disorder that can trigger abnormally high blood pressure in pregnancy is associated with increased risks of death in offspring from birth to young adulthood, finds a study published by The BMJ. The findings, based on data from over two million individuals in Denmark, show increased risks [...]

Rapid, sensitive sepsis diagnosis can now be performed with biphasic amplification in a dried blood matrix Bloodstream infections (BSIs) and sepsis result in high morbidity and mortality, particularly in critically ill patients and neonates. Patient outcomes can be significantly improved by administering antibiotics within three hours of initial symptoms, but current diagnostic methods take much longer to diagnose BSIs/sepsis. [...]

Working Principle For Coagulation Analyzer What is coagulation? Coagulation is the process by which a blood clot is formed in order to stop bleeding. It involves two main pathways – extrinsic and intrinsic pathways. The extrinsic pathway is initiated by tissue factor produced as a result of damaged blood vessels. Coagulation Analyzer A blood coagulometer is an analyzer used [...]

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 [...]
