"SCIENTIFIC HATCHERIES"

In these digital compound instruments, a video camera is built into the traditional microscope chassis.

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

Consists of one support, 5 plumb lines, 1 roll of tape, and 5 figures (triangle, L, trapezoid, parallelogram, parallelopiped). This kit helps students in the individual research of the center of gravity of a flat body, the conservation of the result on paper, the possibility of a graphic verification, and the discovery of the geometric research method.

Durable, hardwood Test Tube Rack holds 6 tubes measuring up to 25 mm in diameter, and features 6 draining prongs.

Height-adjustable, corrosion-resistant stainless steel lab jacks capable of supporting heavy loads.

Durable plastic jumbo test tubes made from PET.

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.

Tough vinyl lab aprons are resistant to lab reagents, acids, alkalis, oils, and grease.

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.

For demonstrating the differential expansion of two metals as shown by the curvature produced when the bar is heated. Each metal band is 200 x 15mm and riveted together.

Ammonites grew their shells from calcium carbonate and grew constantly throughout their life span. A relative of octopi and squids today, ammonites swam through the open ocean, preying on smaller marine animals.

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.

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.

This pulley is ideal for use with photogates sensors. Pulley is mounted on free-running ball bearings with minimum friction. Mounted on a removeable rod of 150 x 10 mm diameter.
Diameter 65 mm with spokes
Ideal for use with Photogates

This model shows the internal structure and operating principles of an air cooled two-stroke engine. All parts are aluminum and plastic. Ignition is shown via a small bulb. Carburetor and fuel supply are also sectioned. Hand crank is provided for manual operation. Mounted on a base.

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