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.

Designed based upon the Science magazine Inquiry Based Instruction (IBI) award winning lab, “How We Got Here: An Inquiry-Based Activity About Human Evolution” (Price, Science, Dec. 21st, 2012, Issue 338(6114):p1554-55), students collect and analyze data from the replica skulls to uncover and correct fundamental misconceptions about evolution.

This multiparameter meter is a rugged, waterproof multiparameter meter. This meter's multi-sensor probe allows for the measurement of key parameters including pH, ORP, conductivity, dissolved oxygen, and temperature. The multiparameter probe transmits readings digitally to the meter, where data points can be displayed and logged. The complete water quality meter is simple to setup.

The Motion Encoder Cart is a dynamics cart compatible with the Vernier Dynamics Cart and Track System. The Motion Encoder Cart replaces a motion detector when used for dynamics cart-on-track activities. An optical sensor beneath the dynamics cart senses the passage of the cart over a marked strip on the track. The position information is sent as an encoded IR signal to a receiver at the track’s end. By avoiding the possibility of stray sound reflections, this optical-only system provides excellent, repeatable, and noise-resistant motion data.

The handheld LCR meters measure inductance, capacitance, and resistance quickly and precisely.

Explore how climate change may lead to health problems.

The AND1100 Fluorimeter tests for metals in water in two steps and less than two minutes, significantly reducing the test expenditures, complexity and wait times experienced in traditional tests. Powered by DNA, it is a breakthrough in streamlining the water analysis and reporting processes. The AND1100 Fluorimeter is a platform centric portable device for heavy metals testing for drinking water and industrial water supplies. It uses an extremely sensitive measurement technique in tandem with ANDalyze sensor kits to determine the toxicity levels of heavy metal contamination. Sensor kits are available for lead, uranium, copper, mercury, zinc, and cadmium; with more to come.
