"SCIENTIFIC HATCHERIES"

This Ray Box is a simple, safe, and sturdy source of projected light for many classic optics experiments. Best of all, you don't need a completely dark room to conduct optic experiments due to its high-intensity light!

These TPX jugs have a non-drip spout and excellent thumb grip on their handle making them perfect for every laboratory and classroom setting.

A dramatic visualization of air pressure. This 1000 ml bottle has a balloon attached to its neck and an additional hole in its base fitted with a rubber stopper. You cannot inflate the balloon with the stopper in place, but remove the stopper and the balloon easily inflates. Replace the stopper, fill the bottle with water, remove stopper and Whoosh! – a geyser erupts!

This laboratory set includes a retort base made of corrosion resistant, powder coated steel, a stainless steel rod featuring a 10 mm x 1.5 mm metric thread and three cast iron support rings.

Use PCR to determine if your chickens are male (ZZ) or female (ZW).

Use PCR to determine if your emus are male (ZZ) or female (ZW).

Set includes (1) base, (1) rod, (1) beaker tong, (1) crucible tong, (1) tripod stand, (1) wire gauge, (1) bosshead, (1) clamp, (1) retort ring with bosshead, (1) burette clamp double, (1) test tube holder, (1) test tube stand (z-shape), (1) test tube brush, and (1) spatula.

A space saving alternative to wire racks, these stackable submersible plastic racks are constructed of a special blend of autoclavable polypropylene. This mold-resistant plastic is both safe and sterile for use in the lab. The white racks will sink in a water bath and maintain their stability even in agitated water. Each rack features end plates for labeling as well as numbered and lettered rows for tube identification. Size of each: 9 3/4" x 4 1/10" x 2 1/2".

Use PCR to genotype your own chickens for the recessive white allele that causes white plumage.

Superior quality double wall calorimeter with easily removable spring heating element. Operates on 3-6V DC at approximately 5 watts. It consists of an inner aluminum 150mL resevoir, aluminum outer, plastic insulator ring, and styrofoam lining to minimize heat loss. Lid accepts heating element, stirrer, and thermometer cork. Includes cover cap.

The rolling friction car kit provides four cars for exploration into the force of friction. Each car provides a set of different material wheels (wood, fabric, soft rubber, soft silicone) with a different coefficient of friction. By setting the cars in motion with equivalent velocities, one can qualitatively demonstrate the frictional properties of rolling without slipping.

Use PCR to genotype your own chickens for the frizzle allele that causes curly feathers.

The determination of the gravitational constant ‘g’ is one of the most fundamental and early physical constants students must derive and observe. This kit has a wooden base, 1.1m rod and a movable electromagnet. The electromagnet can be moved anywhere on the rod and is powered by the timer. When the ball is released, the timer is triggered and stopped once the ball has landed on the base for a precise measurement and then calculation of ‘g’. Supplied with manual.

These half size torsos are a great starter torso for any classroom. Available in three different part counts all of these models show basic human anatomy and systems. The most basic figures illustrate general structure of organs and systems and are cast with a cutaway skull exposing a cast brain. The Dissectible head version also shows more advanced head and neck structure, as well as a half brain removable from inside the skull. The most advanced version shows all of the same items as the dissectible head version and also includes a removable female insert, and shows musculature on the left side.

Comprises an inverted “U” tube with its ends closed by sintered discs. For use in experiments involving the measurement of cell EMF under conditions of forward, zero and reverse current flow. The bridge comprises an inverted “U” tube with its ends closed by sintered discs. This apparatus provides a more effective method of making reversible cells then the wet filter paper or agar gel methods. Dia. of arms 13mm, overall width 80mm, overall height 100mm.
