Fluorescent molecules are compounds that absorb light of one wavelength, then re-emit light at a longer wavelength. This emitted light can be quantified using fluorescence spectroscopy. Molecular and cellular biologists use fluorescent compounds to label proteins, gels, and even cellular organelles. In many ways, fluorescent compounds have revolutionized research in the life sciences.
If your school owns MEL-TEMP units, this is for you. Our Wide-Range Temperature Probe fits perfectly into the thermometer slot of a MEL-TEMP unit. This is a great option, especially if your school is no longer using mercury thermometers. The Wide-Range Temperature Probe can be used safely to 330°C, and its RTD (resistance temperature detection) technology ensures accuracy to ±0.1°C.
When we originally created the popular Periodic Table application in LabQuest, we realized that there was a gold mine of information in the database that could eventually be used to create periodic table plots, such as atomic radius vs. atomic number, first ionization energy vs. atomic number, etc. Most introductory chemistry courses introduce periodic trends by having students create these kinds of plots and look for recurring trends in many chemical and physical properties. You can do this in LabQuest App.
With ultra-safe design, this spectrum tube power supply will provide a simple means of viewing gas discharge spectral lines with any of our spectrometers. Unlike other designs, this system has no exposed high voltage. The gas tubes are permanently enclosed in plastic carriers that protect the tubes from breakage. There are no through-the-glass electrodes, so the tubes last far longer than older designs. The Power Supply will energize one tube at a time, and includes storage space for an additional six tubes. All tubes sold separately.
Investigating Chemistry with Inquiry is a new lab book which contains 25 inquiry-based chemistry investigations. Each experiment includes a preliminary activity, teacher information, sample researchable questions, and sample data for those researchable questions.
Integrated-Science students Erin Smyers and Nicole Loughner from Homer-Center High School in Homer City, PA, worked with their science team leader, Mark Shopland, to investigate the pH changes in an oxidation-reduction reaction. The students chose to work with Thionin based on the demonstration “Thionin – The Two-Faced Solution” published by Flinn Scientific Inc. (Publication No. 0815.00).
Vernier and Ocean Optics will team up again this summer to offer a two-day spectroscopy workshop, entitled “Spec 101”. The workshop will be held on June 17 and 18 at the Ocean Optics headquarters in Dunedin, Florida.
It is an excellent opportunity for teachers to see the latest in spectroscopy technology and obtain valuable hands on experience with a wide variety of laboratory experiments. Last summer’s inaugural workshop was a rousing success, and this year’s is shaping up to be even better. Please visit the Ocean Optics education website for all the details and registration.
