What type of ultrapure water should I use for HPLC (UHPLC) analysis?

As “HPLC-grade water” gradually becomes a household word throughout the scientific industry, the importance of ultrapure water in HPLC and UHPLC analysis is no longer a new topic. Achieving reliable and reproducible results is an eternal pursuit for all scientists, so RephiLe is willing to spare no effort to emphasize how to select a proper water purification system that can

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 should I do when my lab is flooding? How can I prevent water leakage?

A flood in a lab? Yes, it does happen when a certain of lab equipment, such as water purification system, is broken unexpectedly, especially in wet labs! And floods in the laboratory are costly and can cause serious damage, disruption, and even personal injury. Thus, avoiding laboratory from flooded is a must do. Today, let us explain the countermeasures for

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

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
