Are you looking for professional development using Vernier technology? We offer free hands-on workshops across the country, online training opportunities, and options for personalized professional development. Each option allows you to immediately apply your new learned skills in the laboratory...
It might be difficult for a student to see where absorbance spectroscopy and Beer’s law could be useful to a chemist. But, what if the technique is used to analyze poisoned wine from a crime scene? This definitely piqued the...
A Safety Data Sheet (SDS) serves the same purpose as a Material Safety Data Sheet (MSDS). They provide a formal and consistent format, in 16 sections, that are organized in a specific order to make them easy for people to...
A much easier and more reliable method to measure the concentrations of specific ions is to use ion-selective electrodes (ISE). Vernier offers these five options: ammonium, calcium, chloride, nitrate, and potassium. By adhering to a few best practices, students can...
Fluorescence spectroscopy is a very sensitive and delicate technique. It often requires a few attempts before getting great data. In our chemistry department, we have come across a few common problems and would like to share some solutions that fix...
Are you presenting a poster or a talk at an upcoming conference? Plan your schedule to include a visit to the Vernier booth at these upcoming conferences. One of our knowledgeable chemistry staff scientists will be available to introduce new...
Molecular biologists and biochemists are always talking about their sample’s 260/280 ratio. It is so commonly used that entire instruments are dedicated to displaying this value when analyzing a sample. The A260/A280 ratio is a procedure that tells scientists the...
Have you ever done an experiment that you wish you could repeat with different chemicals or concentrations but lacked the time and materials? This is......
Flash photolysis spectroscopy is a type of time-resolved absorbance spectroscopy that helps students investigate chemical reaction order as well as the basics of photochemistry. This technique was so groundbreaking that the 1969 Nobel Prize in Chemistry was awarded to the...
