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,...

Cuvettes are essential components in spectroscopic analysis. Selecting the wrong cuvette can lead to inaccurate readings, poor reproducibility or even total measurement failure.This guide explains the difference between quartz and glass cuvettes, helping you choose the right one for your UV/Vis spectrophotometer. What Is a Cuvette and Why Does Material Matter?...

Cuvettes are small, simple pieces of laboratory equipment, but using them correctly is essential for obtaining accurate, repeatable absorbance data. Improper cuvette handling is one of the most common causes of error in UV-Vis spectroscopy. This guide explains how to use a cuvette properly, from preparation and cleaning to measurement and storage.
