NSTA Recommends recently featured the Go Direct® O2 Gas Sensor. In his review, Martin Horejsi used the wireless sensor to collect data during various investigations, including an out-of-the-classroom experiment on an airplane. He highlighted the ...

Instrumentation is used in the undergraduate chemistry curriculum to help demonstrate the fundamental aspects of chemical reactions and demonstrate how it can be used to determine certain properties of a chemical system. For example, absorbance spec...

When it comes to bringing data collection to the classroom, knowing where to start can be tricky. The team at Vernier Science Education compiled a list of our favorite experiments from our lab books—from elementary school science to college-level e...

Whether you are teaching general or upper-level college chemistry courses, our affordable sensors and instrumentation make it possible for every student to participate in hands-on learning. Our combination of sensors, software, college-level experi...

Do you teach environmental chemistry? Are you looking for lab experiment ideas and equipment? Students taking environmental chemistry will learn basic techniques for chemical analysis of environmental samples, including air, water and soil. Many o...

In an effort to help you and your students better understand spectrometer absorbance readings, we’ve collected a few commonly asked questions: Why don’t absorbance readings have units? Absorbance readings are unitless because they are calculate...

Are you a member of the American Chemical Society (ACS)? I’ve been a member for 10 years and currently serve as the Secretary for the local Portland Section. ACS is a scientific society of chemistry professionals that includes students, educato...

Did you know that you really can’t calibrate a Vernier Drop Counter? Instead, you are actually calibrating the tip of the titrant reservoir. The Vernier Drop Counter is a modified photogate designed, through the software, to monitor drops of ...

An Oxidation Reduction Potential (ORP) Sensor measures the activity of oxidizers and reducers in an aqueous solution. It is a potentiometric measurement from a two-electrode system similar to a pH sensor. Sometimes it is also referred to as a ...

Tip #1: Keep Your pH Sensor Hydrated Storing your pH Sensor in storage solution is important for preventing the reference electrolyte from leaching out, keeping the junction clear, and keeping the glass tip hydrated. If you're out of pH storage so...
