The acylation reaction, also known as acylation, is a key process in organic chemistry where hydrogen or other groups are replaced by acyl groups. The compound providing the acyl group is referred to as the acylating agent. The reaction can be expressed as: RCOZ + SH → RCOS + HZ...

Aromatic hydrocarbonization reaction is a widely used method in enzyme immobilization technology. It involves alkylating and aromatizing polymers with halogen-substituted aromatic rings or heterocycles, followed by reactions with amino, phenol, or sulfhydryl groups on enzyme molecules under alkaline conditions. Aromatic hydrocarbons, commonly referred to as aromatics, are fundamental components of...

Halogenation reactions refer to the process where a hydrogen atom or other groups in an organic compound are replaced by a halogen atom to form halogen-containing organic compounds. This reaction is a cornerstone of organic synthesis, enabling the production of a wide range of halogenated compounds with unique properties and...

Spotting Capillary Spotting capillaries are typically produced by tangentially connecting glass capillary tubes and pipettes. The manufacturing process involves three main steps: tip treatment, tube wall protection, and filling. Among these, tip treatment is critical, as the shape and size of the tip significantly influence the quality and stability of...

A glass spotting capillary is a thin, cylindrical, or micro-tapered glass tube characterized by its slender structure. With diameters often below the millimeter scale and lengths extending up to tens of centimeters, these tubes feature thin walls, making them ideal for various laboratory operations. Common uses include liquid distribution, mixing,...

    The main raw material of PTFE sample capillary is polytetrafluoroethylene (PTFE), so it has excellent high temperature resistance, corrosion resistance, low friction coefficient and other characteristics. PTFE (polytetrafluoroethylene) is a high molecular polymer known for its extraordinary chemical stability. It is resistant to almost all strong acids, alkalis...
