The baseline tactile monofilament evaluator, foot set, measures cutaneous sensory perception threshold of the feet. Used to test sensation levels, and obtain objective data for accurate reporting on the status of diminishing or retuning sensibility.

A set of 15 samples of different materials used to challenge students to identify materials based on measurement of their density. For some specimens this will be straightforward. In other cases, it will lead to a discussion of uncertainty in measurements and data, and to an awareness that different materials may have nearly the same density.

The GL201 DM System offers lab accurate POC glucose testing with all the necessary connectivity solutions to seamlessly transfer results into your electronic database.

Premium introductory collection features 12 palm-sized specimens that depict the variety of colors and forms found in minerals. Each specimen is numbered and keyed to an ID sheet featuring additional data about each item. Includes an information booklet and a magnifier.

Transect tape provides K-12 students with a simple, hands-on tool to explore scientific sampling, spatial measurement, and biodiversity observation, fostering real-world inquiry and data collection skills.

The Hb201 DM System offers lab accurate POC hemoglobin testing with all the necessary connectivity solutions to seamlessly transfer results into your electronic database.

Erlab’s HALO Carbon is a ceiling mounted laboratory grade air filtration system working to purify the air from fugitive emissions present in the laboratory, while also providing real-time communication with the laboratory manager and users, of the air pollution levels and 24/7 data.

Ward's® 1100 Visible spectrophotometer is perfectly designed for high school and college students completing general analysis and experiments such as Beer-Lambert, Absorption Spectrum, Transmittance, Chlorophyll, protein (biuret test) and more. An included visible wavelength spectrum chart on the instrument panel allows the user to make the correlation between a wavelength number to an actual color on the visible light spectrum. The built-in secondary filters reduce stray light and increase precision. The design is "Student-Proofed" making this a durable unit for years of use. Large digital display makes reading much easier and the new USB interface allows for the collection of data via a computer. This spectrophotometer is designed for use with ¹/₂" (13 mm) round tubes or 10 mm square cuvettes. an adapter is supplied at no additional charge for 10mm square cuvettes. High quality silicon photodiode detector and 1200 lines/mm grating assures high performance. Auto zero function, one-touch blanking and built-in automatic filters for easy operation. Large digital display allows for quick and easy readings. Optional Windows(R) based software for easy data collection and application expansion to Standard Curve and Kinetics, Abs. and %T is available. Data can be easily exported to Microsoft Excel(R) for further processing and analysis. The software is designed for Windows based PCs, using Windows 2000, ME, or XP. Model 1100 measures Absorbance, Transmittance and now includes a USB port.

The LaMotte® Digital Tapwater Tour offers a hands-on exploration of water quality for grades 4 to 8 through an interactive, digital manual. Students test their own tap water samples using TestTabs® reagent tablets, with everything they need available in the digital instructor and student manuals, including test procedures, data sheets, and puzzles.

The Ohaus® Starter Series of electrodes include pH, reference, oxidation-reduction potential (ORP), conductivity, dissolved oxygen (DO) and temperature electrodes.

The 1100RS Visible Spectrophotometer features an accurate 10nm bandpass model and is designed for use with ¹/₂" (13 mm) round tubes or 10mm square cuvettes and is perfect for most laboratory/classroom applications. An adapter is supplied at no additional charge for 10 mm square optical glass cuvettes. The high quality silicon photodiode detector and 1200 lines/mm grating assures high performance. Auto zero function, one-touch blanking and built-in, automatic filters allow for easy operation. The large digital display allows for quick and easy readings. This visible spectrophotometer works with optional Windows® based software for easy data collection and application expansion to Standard Curve and Kinetics, Abs. and %T and Concentration, etc. Data can be easily exported to Microsoft Excel® for further processing and analysis. The software is designed for Windows based PCs using Windows® 2000, ME, or XP. A USB and RS-232 port is available on this spectrophotometer as well as Absorbance, Transmittance, Concentration (C) and Factor (F) modes. Each mode can be quickly selected with the touch of a button.

Versatile and portable meters for wherever your lessons take you.

Vernier Chemistry Investigations for Use with AP* Chemistry lab book provides a comprehensive set of resources for the AP Chemistry teacher, including sample data, sample analysis and calculations, and helpful guides to assist in preparing reagents and chemical solutions. In addition, a carefully chosen set of step-by-step instructions for operating probes and software is included to help students make the best use of available lab time, while retaining the spirit of an inquiry environment.
