Water for Cell Culture | what type of water should be used for cell culture?

Water is extensively used in the key procedures of cell culture process. It is mainly used as a solvent in the preparation of buffers and media, other roles including the dissolution of additives and drugs, rinsing of bioreactors, plastic ware and glassware, etc… Contaminants in water may influence the growth, morphology as well as behavior of cultured cells, thereby affecting

Who is the “key man” in an ultrapure water purification system?

An integrated ultrapure water purification system, such as Genie G, contains multiple purification technologies. In order to provide consistent and stable ultrapure water quality, a powerful ultrapure cartridge is essential among the “final polishing” step of ultrapure water production. When speaking of ultrapure water, most customers will think of two important concepts: resistivity and TOC value. However, do you know

What is Electrodeionization (EDI)? How does Electrondeionizaton work?

What is Electrodeionization (EDI)? EDI technology has grown in popularity in water purification industry. It effectively removes impurities from water using a unique combination of semi-permeable membranes, ion exchange resins and a direct electric field. The ion exchange resins are continuously regenerated without the need of cleaning chemicals. To understand how the EDI purification technology actually works, let’s go down

What is the Difference between DI water and UP water

Often, when you are doing experiments, the ions in water might be interferences and your tests come out with wrong answers. Getting the right water for your need is one of the important keys to work properly in the lab. However, when looking for the right water purification system, people may get confused about the difference between deionized (DI) water

Essential water quality for COVID-19 testing

COVID-19 or novel coronavirus is wildly spreading across the world and its outbreak has set alarm bells ringing globally. Effective diagnostic methods are crucial to the early diagnosis, prevention and control of the pandemic, such as nucleic acid detection and antigen-antibody detection. At present, nucleic acid test plays a critical role in the diagnosis of an active COVID-19 infection, especially

Which grade of water to use for Silver Staining

Silver staining is used to detect proteins after electrophoretic separation on polyacrylamide gels. Among the various protein detection methods, the technique of silver staining has gained wide popularity because of its higher sensitivity (in the low ng range) than that of Coomassie blue. Meanwhile, it can be achieved with simple and inexpensive laboratory reagents and no complicated and expensive hardware for the

Standards Set by USP on TOC Test

TOC, short for (Total Organic Carbon), is the total amount of carbon in water dissolved and suspended organics. There are many kinds of organics in water, and different organic compounds have different carbon content. TOC is often used as one of the most important composite parameters in the assessment of water quality and an indirect measure, as carbon, of organic molecules
