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...
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 ...
NSTA Recommends recently featured the Go Direct® Motion Detector in the article, "The Vernier Go Direct Motion Detector: A Modern Twist on a Timeless Design," Reviewer Martin Horejsi provides interesting background and history on ultrasonic mot...
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...
