Drop Counter as Fraction Collector

Although the Drop Counter was developed to record drops during titration, attaching the Luer-lock stopcock to the outlet of a chromatography column adapts it for use as an inexpensive fraction collector for column chromatography.

Spectroscopy 101 Workshops

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 18 and 19 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.

Creative Classroom Solutions

Peter O’Connor, a teacher from Boonsboro High School in Maryland, described a situation facing many teachers—lots of students and only a few computers.

“Having used Logger Pro for many years dating back to the ULI days, my school has been happy using it in our labs. However, as class size increased, we have had issues with maintaining a small lab group size for each lab. This is a large issue when it comes to doing Vernier labs with computers.”

Spectrophotometric Analysis of the Metals in a U.S. Five-Cent Coin

Vernier consultant, Walter Rohr, came across an article published in the February 1989 Journal of Chem Ed that described a method of resolving mixtures with overlapping spectra without determining molar absorptivities or complicated mathematics. The method developed by Blanco called Multi-Wavelength Linear Regression Analysis, or MLRA, allows the composition of a binary mixture with overlapping spectra to be resolved with only three measurements—the absorbance of a standard solution for each component, and the unknown mixture itself.

LabQuest Earns Five-Star Review

The Vernier LabQuest just received a wonderful review in MultiMedia & Internet@Schools, an educational publication. The review gave the LabQuest a 5-Star rating (out of 5) with the following grades:

  • Installation: A
  • Content/Features: A
  • East of Use: A
  • Product Support: A+

“Students will enjoy using LabQuest…. I was impressed by the rugged construction. This is definitely a tool that will last, which makes it an excellent buy—especially with today’s tight funding…. I have no doubt that LabQuest is going to get plenty of use in my classroom. I would highly recommend it for every classroom that is serious about engaging students in meaningful scientific investigations.”
