Organic Microporous Membrane: Organic microporous membranes are made of organic polymers and can be produced with different pore sizes and molecular weights through various manufacturing methods. Common materials for organic microporous membranes include polyamide, polypropylene, and polysulfone. These membranes exhibit high filtration efficiency, good mechanical strength, and strong corrosion resistance....

The sterile microporous membrane is a filtration material made of high-molecular-weight chemical compounds, featuring a micro-porous structure with uniform pore distribution and high porosity, ensuring no medium detachment. It is primarily used for filtering aqueous solutions, often referred to as water system membranes. This type of membrane is non-toxic, hygienic,...

The phenomenon of choosing or using cuvettes improperly, leading to the inability to measure or causing measurement errors, often occurs in experiments and is easily overlooked by laboratory personnel. The definition of the ultraviolet (UV) region is 190-400nm, and quartz cuvettes can be used in the range of 190-900nm, while...

      When using cuvettes, ensure that the two transparent surfaces are completely parallel and placed vertically in the cuvette holder. This ensures that the incident light is perpendicular to the transparent surface during measurement, avoiding losses due to light reflection and ensuring a fixed light path. Cuvettes are...

A medicine spoon is an item related to pharmaceuticals. Indeed, it is a tool used to handle medications that cannot be touched by hands, typically made from materials such as buffalo horn, metal, or plastic. So, how can a medicine spoon be used correctly? Let's explore below. How to Use...

Choose a laboratory spoon of an appropriate size based on the quantity of the reagent being used. Do not use the spoon to handle hot substances, and avoid contact with acidic or alkaline solutions. After using the spoon, promptly wipe it clean with paper. It is advisable to dedicate specific...
