The proper use and accurate detection of food additives are key to ensuring food safety. UV-Vis spectrophotometers play a vital role in the quantitative analysis of food additives that exhibit light absorption characteristics. This article discusses the basic principles of UV-Vis spectrophotometers and their applications in food additive testing. It also addresses key technical aspects such as sample [...]

The rotor is one of the most critical components of any centrifuge. While the centrifuge provides the driving force, the rotor directly determines how samples are held, accelerated, and separated. Selecting the appropriate rotor not only improves separation efficiency but also helps protect sample integrity, reduce processing time, and enhance laboratory safety. Different laboratory applications require different rotor [...]

In many fields—including food processing, pharmaceutical manufacturing, and chemical production—drying and dehydrating materials are core process steps. Among the equipment commonly available on the market, freeze dryers and dehydrators are two typical examples. Although both aim to remove moisture from materials, their operating principles, results, and applicable scenarios differ vastly. This article will provide an in-depth look at [...]

Spectrophotometers—these seemingly niche instruments are making their way out of the lab at an unprecedented pace. This article helps you choose the most suitable spectrophotometer by examining factors such as identifying your needs, optical path design, light sources and detectors, and resolution. Considerations Before Purchasing a Spectrophotometer Before reviewing any product specifications, please answer the following three questions. [...]

In modern research fields such as life sciences, biomedicine, food science, and environmental protection, experiments involving microbial culture, cell fermentation, enzymatic reactions, and genetic engineering all impose extremely stringent requirements on temperature, shaking frequency, and environmental stability. While traditional single-tier incubators are reliable, their throughput per unit of floor space has gradually become insufficient to meet the demands [...]

A spectrophotometer is a core spectroscopic instrument that enables the qualitative and quantitative analysis of substances based on the principle of selective light absorption. Its theoretical foundation is the Lambert-Beer law. By measuring the absorbance of a sample at a specific wavelength, the composition and concentration of the substance can be accurately determined. As essential equipment in modern [...]

When you visit the hospital, you might worry: Are the instruments the doctors use clean? Is there a risk of cross-contamination? In fact, hospitals have a strict disinfection and sterilization system in place. Among these, there is one unassuming yet crucial piece of equipment that quietly safeguards the safety of every patient—the ethylene oxide sterilizer. Statistics show that [...]

Fume hoods are essential safety devices in laboratories handling chemicals, solvents, and airborne hazards. While most users understand that a fume hood protects them by capturing harmful vapors, a common question remains: where does that exhaust actually go? The answer is not as simple as “outside.” Modern laboratory ventilation systems are designed with controlled airflow, treatment technologies, and [...]

Common contaminants in tap water include enzymes, gases, organic matter, microorganisms (bacteria, viruses), and others. Laboratory water purification aims to filter out various contaminants from water to meet the requirements of chemical analysis and biological experiments. Understanding the types, performance characteristics, and applicable uses of different water purification systems helps laboratories select appropriate equipment based on actual needs. [...]

Laboratories contain numerous temperature-sensitive samples, such as blood bags and vaccines. To ensure the viability and safety of these samples remain unaffected, they must be stored within specified temperature-controlled ranges. Any temperature fluctuations, cold chain interruptions, or unstable storage conditions may cause protein denaturation or sample degradation. This directly impacts the accuracy of test results and the reliability [...]
