“It takes photographs, video clips, time lapse, operates as a webcam, and has a measurement
feature. It is so easy to use that my four-year-olds mastered it in one day! It is durable, and the price is right. I leave it out and the students are able to use it independently. I have other technological tools, such as iPads, [a] projector, [an iPod] Nano, flip cameras, and digital cameras—but my
favorite … tool is the SmartScope!” by

"The smartscope is AMAZING. I love using it on the computer to really analzye objects/specimens, and my students really enjoy seeing the images magnified. Thank you." by

"The Smart scope is working great!! My kindergarteners LOVE it!" by
Karen -- Ohio
"I apologize..... :)
I totally doubted these microscopes when I got the email and thought "whatever! They're going to sit in the closet like the other ones because they'll be too hard to use.."
I was totally wrong....they ARE super EASY! :)" -- Library Media Specialist by

Colorimeter
Product Code: 3275
This cleverly designed, self-contained sensor produces excellent results and will appeal to the Biologist and Chemist. Any reaction that causes a change in opacity, or gives a colour change can be used to study rates of reaction.
It is supplied with four 35 mm slides (red, orange, blue and green) that produce light of a specific and consistent wavelength, and a pack of cuvettes with lids.
The sensor's thick, black casing ensures that colorimetric results are not affected by ambient light.
More Product Information
Applications include:
Enzyme concentration versus rates of protein, starch and fat breakdown
Enzyme inhibition
Lambert Beers law
Acidic breakdown of sodium thiosulphate
Quantitative analysis of sugar
Transmittance (%T) is the amount of light being received, referenced to light sent. Absorbance (Abs) is the amount of light absorbed by the solution.
The Colorimeter is designed to measure the amount of light penetrating a solution.
A white LED is used as the source of illumination, thus it does not heat the solution being studied, giving better control when rate reactions are being studied.
Power for the Colorimeter comes from the EasySense unit.
Four coloured filters are provided to allow for the selection of wavelength of light during an investigation.
Red 630 nm, Green 560 nm, Blue 470 nm and Orange 600 nm.
The cuvettes supplied are made of optical polystyrene, 10 mm x 10 mm with a 4.1 cm3 capacity.
Product Item Contents
