Nature of Heat

Specific Heat Specimen Set

Set of 4 consisting of aluminum, copper, stainless steel, and zinc. Each cylinder is 19 mm in diameter. The length of the cylinders is such that all are of an equal weight, since their masses are equal, their relative heat capacities are directly propor... More.

Pulse Glass

Designed for demonstrating that vapor pressure increases when temperature increases. Apparatus consists of two glass bulbs which are connected with a glass tube and contain a colored, volatile liquid. Holding one of the bulbs in your hand causes the eva... More.

Ball and Ring

Brass ball, 3/4" diameter, fits into brass ring. Ball passes freely through ring when both are at same temperature. After application of heat, as little as 100° C change in temperature, the ball cannot pass through the ring until it cools or un... More.

IR Thermometer/LED Light Pen

This dual-use pen features a super bright white LED on one end and a non-contact infrared thermometer on the other. Both features have separate operation buttons. The IR thermometer has a response time of one second and is protected by a lens ca... More.

Double-Walled Calorimeter with Electric Option

A calorimeter with a double-walled cover will minimize heat loss. The inner and outer vessels are made of aluminum. The calorimeter has a stirrer and support for the inner vessel. Item is now interchangeable and can be used with or without electrici... More.

Radiation Meter

Small and light enough to take anywhere; sensitive enough to detect miniscule amounts of gamma, beta, or X-rays. Excellent for scanning lab work areas and various minerals. Comes with a Geiger-Mueller tube detector. Meter registers 0.1 to 10 mR/... More.

Radiation Can Set

An affordable and simple way to study absorption, emission, and Newton’s Law of Cooling. These two cans are identical except for color: one is black and the other is the natural, shiny finish of the can. With this set, students can determine which... More.

Convection Apparatus

Designed for studying convection currents in the air, this apparatus consists of a metal box with glass front and two acrylic chimneys mounted on the top. Convection currents visible through the glass front are produced by a candle placed under one chim... More.

Conductometer

Demonstrates the conductivity of five metals: silver nickel, steel, aluminum, copper, and brass. Hub is stationary, and is mounted on a plated steel rod with wooden handle. More.

Compound Metal Bar

A classic experiment that never grows old. Two metals (nickel and stainless steel) of different heat expansion coefficients welded together and mounted in wooden handle. Demonstrates unequal expansion of different metals by bending when heated. Includes... More.
