How is the water that comes out of our faucets made safe for consumption?

An instructor's desk constructed of solid oak, oak and hardwood veneers, this unit serves as a complete demonstration center offering a spacious work surface.

The Optical Voice Link Kit is the ideal introduction for those students first learning about the marvels, mysteries and science of light transmission through optical fiber.
Students will be fascinated by hearing their own voices, after it has been converted into light and then coupled into, through and out of an optical fiber. This kit is suitable for science projects, home projects, short audio fiber optic curriculums for schools, and inexpensive classroom demonstrations.
No prior fiber optics experience, special tools or training are needed for students to be able to build, use and enjoy the multiple applications of this kit.

Organized, economical survey of fossils.

Versatile AV cart, great for office or classroom use.

Speakman® Laboratory products are designed to accommodate the needs of laboratories by offering a number of configurations to ensure the perfect fit for virtually any application.

This harmless insect parasitizes the Sarcophaga (flesh fly) pupae. Females usually lay 30–50 eggs in the pupae, which provide food for the Nasonia larvae when they hatch.

Durable analog grain vernier for precise manual measurement, 0 to 10 mm range.

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

Explore the carbon cycle by simulating the production of carbon dioxide due to microorganisms in soil.

The Pressure sensor 400 is the optimal sensor for conducting physical and analytical chemistry experiments, such as approximating the adiabatic expansion of a gas, Charles' law experiments, and ideal gas law investigations. It measures absolute pressures from 0 to 400 kPa and operates with excellent accuracy over a wide temperature range. The robust metal fittings allow for a tight, leakproof seal to reaction apparatus.

Ideal tool for aquatic ecosystem studies. Collect periphyton samples with ease using this specialized sampler, perfect for water quality and aquatic ecosystem studies.

Explore charging by induction and discover how a Leyden jar stores electric charges.

Add the Vernier Optics Expansion Kit to your Vernier Dynamics System to conduct optics experiments, such as image formation with lenses and light intensity vs. distance. You can even use the kit to build a basic telescope.

The handheld DEF (Urea) refractometer features the largest, easiest-to-read scale available with clear, sharp figures, screen shading and incredible contrast. This significantly enhances overall precision, even when several different people use the refractometer.

A comprehensive set designed for safe and repeatable observation of electrostatic field lines using various electrode patterns.
