Freeze drying, also known as lyophilization, is widely used in the pharmaceutical industry. The process exposes a product or sample to subfreezing temperatures, then uses a high-pressure vacuum to extract the water and convert it to steam. A condenser is used to collect the vapor, convert it to ice crystals and remove it. After the initial freeze-drying phase, the product [...]
With the continuous development of science and technology, Glassware Washer, as an automatic cleaning and drying equipment, has become a common equipment in modern laboratories. This article will introduce in detail the working principle, advantages, application scope and after-use maintenance of the laboratory bottle washing machine. The working principle of laboratory Glassware Washer is based on advanced mechanical and electronic [...]
1. Multi-parameter water quality analysis instrument A multi-parameter water quality analysis instrument is an instrument that integrates a variety of sensors and analysis modules, which can simultaneously measure and analyze multiple parameters in a water body. They are usually characterized by high precision, high sensitivity and high stability, enabling fast and accurate acquisition of water quality data. Common multi-parameter water [...]
1. What is a pathology laboratory The pathology laboratory is an important part of the pathology department of the hospital and occupies an important position. The task of the pathology laboratory is to make various pathological films, including: rapid pathological film preparation, puncture and exfoliated cell pathological film preparation, HE preparation of routine biopsy tissue, immunohistochemistry, special staining, molecular [...]
American scientists wrote in the latest issue of "Molecular Therapy" that they recently developed a mature mouse model and used gene therapy for the first time to restore the hearing of an aged animal model. The latest method is expected to be applied to humans. By 2050, one in 10 people is expected to suffer from some form of hearing [...]
According to the 1992 version of the NSF49 standard in the United States, the medium of biosafety level 1 (P1) refers to ordinary harmless bacteria, viruses and other microorganisms; the medium of biosafety level 2 (P2) refers to general pathogenic bacteria, viruses and other microorganisms The medium of biosafety level 3 (P3) refers to microorganisms such as potent/lethal bacteria [...]
Infinite possibilities in childhood, witnessed by the Bioevopeak as we grow.Happy Children's Day to all of you!
The Epstein-Barr virus (EBV) is easily spread through bodily fluids—primarily saliva—from kissing, sharing drinks, or using the same eating utensils. Not surprisingly then, EBV is also among the most ubiquitous of viruses: More than 90 percent of the world’s population has been infected, usually during childhood. EBV causes infectious mononucleosis and similar ailments, though often there are no symptoms. Most [...]
Did the recent mpox (formerly known as monkeypox) outbreak end because of “network immunity?” That’s the theory being put forward by Belgian researchers at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Copenhagen, Denmark. The year of 2022 saw a global outbreak of mpox, a viral infection that had not previously been documented as having [...]
From hidden areas that are hard to access for cleaning to dangerous dirt traps that provide a perfect home for bacteria to thrive and grow, there are many unseen hazards in poorly planned and managed laboratories. In my career, I’ve been privileged to visit some incredible pharmaceutical facilities and sophisticated manufacturing operations. With stylish, ergonomic, and impactful design, many of [...]
