Removing Broken Capillary Tubes from a Melt Station
Follow the steps below to remove a broken capillary tube from the Melt Station. Caution: Do not handle a broken capillary tube with your fingers. Wear safety glasses or safety goggles.

Yes, Eclipse Glasses (EC-GL50), are safe for viewing the sun. Their manufacturer, Rainbow Symphony, Inc., states the following on their website http://eclipseshades.com:
Eclipse Shades lenses are made of our exclusive scratch resistant optical densi...
By far, the most common problem with getting the SensorDAQ up and running has to do with the NI-DAQmx USB driver software.
Here are some tips for troubleshooting DAQmx, as well as some other issues that commonly present problems:
Did you insta...
First try the following:
1) Connect the sensor to a Vernier interface and the default readings in kPa are NOT around 101 kPa
AND
2) Connect the 20 mL syringe from the Accessories Kit to the sensor, move the plunger inward and the pressure reading...
Yes, the channels are identified by their primary wavelength - 615 nm, 525 nm, and 465 nm. The color of the traces on the graphs correspond to the colors that are detected:
615 nm - red
525 nm - green
465 nm - blue
Interestingly, the color of trace...
The Conductivity Probe (CON-BTA), as well as the Go Direct® Conductivity Probe (GDX-CON), electrode body is made of ABS plastic with a graphite electrode while the Platinum-Cell Conductivity Probe (CONPT-BTA), electrode body is made of epoxy with...
In order to calibrate a Conductivity Probe, or to confirm that a saved calibration is accurate, you should have a supply of standard solutions that cover the range of values you will be measuring. There are multiple ways to obtain these solutions:

No. None of our ORP sensors can be used for Cyclic Voltammetry; but we do offer an instrument that will do this directly: Go Direct® Cyclic Voltammetry System (GDX-CVS)
The Oxidation-Reduction Potential (ORP) Sensor is a two-electrode system t...
There are a few things to consider to help improve the performance of your ORP readings:
1) The accuracy of a new electrode is +/- 20 mV. If you are seeing changes over time within 20 mV of a value, then it's just noise.
2) If the value is d...
The ideal test solution for an ORP electrode is a commercially-produced standard. Many companies sell ORP standards: Hach, Cole Parmer, and Hanna are three examples.
You can also prepare you own test solution. Here are the recipes for two:
