"Metallic+Beads"

Quality beaker made from low-expansion borosilicate glass.

This working model thermostat will demonstrate how differential expansion is used to control temperature. A bimetallic strip is used to open or close an electric circuit when temperature changes. The contacts will carry about three amperes. The unit can be operated with a 6 V lantern battery, low voltage power supply, or a blow dryer. Mounted on a metal base; approximately 15 cm high.

Are chemical reactions reversible?

The High Current Sensor has a range of ±10 A. Current is measured with a Hall Effect sensor, which uses the magnetic field created by the current and therefore does not add a resistive element to the circuit. A metal shield over the Hall Effect chip reduces the influence of external magnets. A replaceable fuse protects the equipment and circuit.

Get hands on with dew and condensation.

Calculate Atomic Volume and Radius.

High Quality for the Classroom.

Maxwell apparatus with flywheel to demonstrate momentum, friction, and oscillation.

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.

Convenient sets of glassware expertly packaged custom-fit foam inserts for worry-free transport and safe storage.

Ideal for simulating various electrical values.

With the magnet is on the outside, it's easy to see the science behind these eddy tubes.

High Quality for the Classroom.

This workbench, Made in the USA, is perfect for storing different large and small items. The art bench is designed to be used by four people. One side of the workbench has storage for flat items, like paper or metal sheets. The six locking drawers are dovetailed and have full extension glides. The opposite side of the workbench has two locking doors with an adjustable shelf inside the storage cabinet.

Cylinder set for demonstrating density investigation and specific heat experiments.
