This is really a difficult question to answer and will vary battery to battery. We can't provide a specific shelf life for the batteries but they will actually last longer if they are used periodically. Lithium batteries degrade slowly over time, e...
To prevent students from "fudging" sensor data, users cannot change sensor readings taken in our data collection apps such as Graphical Analysis and Spectral Analysis. However, data that is manually entered into the app by the user can be modified a...
There are a few ways in which to use Vernier sensors with LEGO hardware and software. But those connection options are fairly limited, as outlined below.
The NXT Sensor Adapter (BTA-NXT) provides the ability to connect certain Vernier LabQuest a...
While Pivot, Logger Pro and Vernier Video Analysis all offer a form of video analysis, Pivot is quite different from the other two.
Vernier Video Analysis and Logger Pro provide a general purpose video analysis tool for frame-by-frame analysis. ...

WHAT IS THE A260/A280 RATIO?
This ratio is used to determine the purity of a DNA or protein sample. Contamination of a nucleic acid solution by proteins, carbohydrates, and other organic molecules can be determined using a procedure called the A2...
Yes, the following Vernier spectrometers can be used to assess DNA purity and concentration:
Go Direct® UV-VIS Spectrophotometer (GDX-SPEC-UV)
Vernier UV-VIS Spectrophotometer (VSP-UV)
Go Direct® Fluorescence/UV-VIS Spectrophotometer (GDX-SP...
A full spectrum is taken in order to identify the wavelength for analysis. If you already know the wavelength for analysis, then a full spectrum is not necessary. To set up data collection for modes other than full spectrum, follow the instructions ...
We have posted several Spectrometer lab experiments on our website for all of our spectrometers. To find the labs, go to the individual spectrometer's webpage and click on the "Experiments" tab.

If your spectrometer isn’t calibrating or is showing unusually noisy or high absorbance values (often above 3 or blank), the issue may be due to insufficient light reaching the detector. This happens when:
The light source is weak in a certain...
