"SCIENTIFIC HATCHERIES"

Durable plastic jumbo test tubes made from PET.

This filtration assembly is used for vacuum filtration of tissue culture media, biological fluids, HPLC and other aqueous solutions.

Bony fish first evolved during the Paleozoic era, over 400 million years ago. This fossil replica represents a mold of a ray-finned fish that died and was buried in the ocean.

With this stainless steel mirror, students can perform experiments using light rays with plane, concave, and convex mirrors all in one convenient and easy to use tool. The flexible metal curve can be switched to convert from a concave to convex mirror.

This life size replica of a human skeleton is painted to show the points of muscle origin in red and insertion in blue along the left side. Quality hardware allows easy movement of major joints and 3 part skull is removable for closer study of jaw and teeth.

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, a support ring and a three-pronged coated clamp.

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

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!

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.

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".

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.

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.

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.

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.

The top disc that can be fixed on the rod has holes for holding pipettes while the lower one has pilot holes where the pipette tips rest and liquids drain down to the base. These discs can be adjusted on the rod according to the length of the pipette. The arrows provided on the discs should be kept parallel to ensure that corresponding holes are being centered.
