It is not possible to use our software to perform a typical custom calibration on any of our spirometers. But you can adjust the calibration to make them more accurate. You will need a 2L (or larger) calibration syringe to perform the calibration ad...
One experimental set up that is popular for studying Newton's Second Law is the Half-Atwood machine. In a Half-Atwood machine, a dynamics cart is tied off to a mass hanging over a pulley. As the hanging mass is released, the cart is accelerated down ...
There are two issues that may cause this to happen.
1. The reading from the Differential Voltage Probe (DVP-BTA) is not centered around zero (0). You can determine this by studying the reading from the Voltage Probe when both solar panels are in t...
The Flow Head of the Go Direct® Spirometer (GDX-SPR) cannot be sterilized by the user. Bacterial filters should be used by each student. These should not be shared. The flow head can be replaced. Please contact Vernier at physiology@vernier.com f...
A replacement stopper for an older style CO2 sensor is available: #6 Stopper for Ethanol Sensor (ETH-STOP).
This stopper is a standard 1-hole, #6 stopper that has been over-bored and slit to accommodate the 1.1 cm stem of the older style CO2 Senso...
Yes, you will need our Instrumentation Amplifier (INA-BTA), one of our interfaces, and our Logger Pro software.
Almost any laboratory instrument that has an output designed to interface with a chart recorder can be connected to our Instrumentatio...
Most people who experience difficulty with DO Probes do so because they do not use the proper setup and/or calibration procedures. The procedure for calibration can be found in the DO Probe booklet that came with the sensor (or found online at www.ve...
