Most MeasureNet customers prefer their student interface stations mounted vertically to avoid the knocks and spills typical of an entry-level teaching laboratory. Many newer lab bench designs, however, lack the vertical shelving and piping typically used to mount MeasureNet stations in older labs.
An Ohio-based company has come to the rescue of vertically-challenged MeasureNet users. Near West Woodworks of Cleveland supplies MeasureNet with customized wooden station stands that elevate stations away from the dangers of acids, bases, drops, and knocks. The stands come in both single and double-sided versions and can be built to match the spatial characteristics of a wide range of benchtops.
But there is more than meets the eye to the story of Near West Woodworks. The shop is an enterprise of Spectrum Of Supportive Services—an organization helping individuals with mental illnesses achieve the necessary skills to lead healthy, productive lives. The organization offers a range of employment services, housing, help lines, and consumer-operated enterprises.
Near West Woodworks has resided in the Ohio City neighborhood of Cleveland for over 35 years and employs some 50-60 individuals in programs that range from woodworking and custom picture framing to construction site clean-up. The company manufactures products for the aerospace industry, national window firms, and local universities.
"These guys are consummate role models in the community," according to MeasureNet's Director of Marketing Michael Kurutz. "They manufacture quality stands that are a great value to our customers. But more importantly, they empower, educate, and encourage their clients toward independence. The day-to-day work they've done over the past three decades has made a quantifiable impact in the lives of many."
MeasureNet's relationship with Near West Woodworks is part of an overall effort by the Cincinnati-based educational technology company to source materials and assembly in Ohio to help generate employment and retain tax revenue in the state. "While we could probably save a few dollars by outsourcing production abroad," adds Kurutz, "the communities we live and work in would benefit little. In the case of Near West Woodworks, there's no question we're doing the right thing."

MeasureNet's President Robert Voorhees (right) and Director of Marketing Michael Kurutz (left) will welcome exhibitors to CERMACS 2007 at the Northern Kentucky Convention Center in Covington, Kentucky. The conference is hosted by the Chemistry Department of the University of Cincinnati in conjunction with the local chapter of the American Chemical Society. As exhibit co-chairs of the 38th annual meeting, Voorhees and Kurutz will oversee the registration and logistics of private sector, non-profit, and academic vendors exhibiting at the conference.
"We're great believers in the ACS Regional Conference Program" says Kurutz. "We regularly exhibit in virtually all ACS regions, thus we have a firm understanding of what's needed to make a meeting successful from an exhibitor's perspective. Bob and I will make the greatest effort to maximize exhibitor exposure."
The pair are planning exhibit areas contiguous to conference sessions, while an an evening reception for attendees is being considered for the vendor's area. Additional features proposed include exhibitor-centric poster sessions and opportunities for vendor workshops.

> MeasureNet Fun-Sci™ Experiments by Probe Type
A typical colorimeter is usually a simple, single-beam optical system to measure “color” in the VISIBLE Spectrum of light and provide ABSORBANCE data at a single wavelength. These systems can cost $1,000 or more for stand-alone colorimeters that merely provide simple ABS data… unless you consider the MeasureNet Model MDBC-138 true Double-Beam, Multi-Functional “Colorimeter” based on a unique set of LEDs (Light-Emitting Diodes)... for under $500! The MeasureNet “Colorimeter” is actually FOUR (4) instruments in ONE (1) compact and rugged box… and works as a colorimeter (to make Beer’s Law Curves for VISIBLE Wavelengths), a UV fluorometer (to demonstrate fluorescence & quenching in certain organic molecules), a turbidometer (to measure the turbidity of particulate & colloidal suspensions) and a phosphorimeter (to analyze the phosphorescence [“glow”] of specific materials).
#1) BEER’S LAW ABSORBANCE & KINETIC SPECTROSCOPY =
This unit can be used as a “simple” Colorimeter to demonstrate Beer’s Law using three (3) high-output VISIBLE Light LEDs at 472nm (BLUE), 525nm (GREEN) and 630nm (RED); which cover over 75% of the classic General Chemistry and Analytical Chemistry Laboratory experiments that teach spectrophotometric measurements. The wavelength coverage of these LEDs allows highly accurate relative measurement of almost all the ROYGBIV Colors. The disposable & unbreakable 10mm pathlength, near-UV plastic cuvettes included with the “Colorimeter” can be used from ~300nm (in the near-UV) to over 1000nm (in the near-IR) for analytical measurements… and come with sealing caps to preserve prepared solutions for future tests. Some of the popular Laboratory experiments defined in MeasureNet’s proprietary FUN-SCIence™ Laboratory Programs and its upcoming “Chem-Lab Library” that provide an excellent framework to create or supplement YOUR OWN Academic Lab curriculum program for Gen Chem, Analytical or Student Research are:
Red / Blue / Green Colorimetric ABS Data for Beer’s Law plots:
• Test for Mineral IRON in your Daily “Eats”… check your Cereals, Breads and special Treats!
• Unsaturated FATS can be easily seen… just get a purple Color using some IODINE!
• Evaluation of Nutritional Food Proteins… React it to get a “BLUE” and see what can be seen!
• Consistency of M&M and Skittles Candy Colors: Is the "blue" true blue or “faux” to you!
• Changing “Colors” of some pH Dyes… [H+] makes them look *new* to our eyes!
• General Colorimetric Assay… for ANION (X, PO4, SO4, NO3, NO2, etc) saves the day!
Unlike most other popular Spectrophotometers… even those costing over $5,000… the MDBC-138 is a TRUE Double-Beam Optical System… and provides a reference cell to “blank” out the reagents used to create a very stable ABS reading for several Organic Reactions. Data from these Labs can be used to calculate rate constants, equilibrium factors and reaction conditions (for thermal, ionic and electrochemical variables). This is a MUST for making accurate kinetic experiment tests. A few of them from our “Library” include:
Dual-Beam ABS Data for Kinetic Measurements:
• The Iodine Test for Starches is GREAT… just Hydrolyze with Amylaze to get a Kinetic Rate!
• Perform REDOX “Clock” Reactions in School… and show Students that Chemistry is Cool!
• pH-based Hydrolysis of p-nitrophenylacetate Ester… try it out in your Lab this Semester!
MeasureNet’s Fun-Sci™ Experiments
Listed below are a few "fun" and "interesting" (aka: non-boring!) experiments developed to provide creative & effective teaching “tools” in laboratory environments using MeasureNet instrumentation—from general College Chemistry to Advanced University Research... as well as for High School Outreach (“Science-In-Motion”) programs.

MeasureNet's design has always offered instructors significant pedagogical flexibility by supporting a wide range of experiment types regardless of whether students work independently or collaboratively. But as Measurenet has expanded from its origins at the University of Cincinnati, its inventory of experiments (and their approaches and styles) has diversified commensurately. You can expect many more selections to become available in the 2006 calendar year.
Adopting electronic data acquisition doesn't require, however, the discarding of proven experiments that build student skills or enhance understanding of important concepts. Older experiments can be easily integrated into syllabi combined with those appropriate for MeasureNet. Others needing conversion can be adapted with the help of our curriculum specialists.
The following are examples of titles for Self-Directed, Inquiry, Technique, and Verification-style experiments using MeasureNet:
