Vector generated image of Electric motor:An electric motor is a device using electrical energy to produce mechanical energy, nearly always by the interaction of magnetic fields and current-carrying conductors .Electric motors are found in a myriad of applications such as industrial fans,...

3D render image of Bell Jar:A bell jar is a piece of laboratory glassware similar in shape to a bell. A bell jar is placed on a base which is vented to a hose fitting, which can be connected via a hose to a vacuum pump. By pumping the air out of the bell jar, a vacuum is formed. Bell jars are...

3D render image of Guinea and Feather Vacuum Tube:This counter-intuitive experiment has to be seen to be believed. Galileo used the traditional guinea (coin) and feather to show how items fall at the same rate in a vacuum despite their relative weights and sizes. Includes 81 cm plastic tube for...

Vector generated Image of Laser Radiation Device:A laser radiation device, comprising: a pumping light emission section that generates and emits pumped light; a fiber laser, including an optical fiber doped with lasantions that are excited by the pumped light, which provides a laser beam...

Vector generated Image of Hand Cranked Vacuum Pump:This unit is ideal wherever a vacuum or pressure is required. Use it for experiments with vacuum tubes, vacuum filters, Magdeburg hemispheres, bell jars, density experiments, and many others.

Vector generated Image of Smart Q Breathing Rate Belt:The Breathing Rate Belt is used with the Smart Q Differential Gas Pressure Sensor (±10 kPa range) to measure breathing rate. The Breathing Rate Belt is a wide nylon belt that can be wrapped around a persons abdomen or chest region. Fitted...

Painting of Rhight Atrium:The right atrium (in older texts termed the "right auricle") is one of four chambers (two atria and two ventricles) in the human heart. It receives deoxygenated blood from the superior and inferior vena cava and the coronary sinus, and pumps it into the right...

Painting of Right Ventricle:The right ventricle is one of four chambers (two atria and two ventricles) in the human heart. It receives deoxygenated blood from the right atrium via the tricuspid valve, and pumps it into the pulmonary artery via the pulmonary valve and pulmonary trunk. It is...

Painting of Left atrium:The left atrium is one of the four chambers in the human heart. It receives oxygenated blood from the pulmonary veins, and pumps it into the left ventricle, via the atrioventricular valve.

Painting of Left ventricle:The left ventricle is one of four chambers (two atria and two ventricles) in the human heart. It receives oxygenated blood from the left atrium via the mitral valve, and pumps it into the aorta via the aortic valve.

Painting of Simple epithelial cuboidal tissue:Simple cuboidal epithelia are epithelial cells in a single layer which have the same height, width and depth; but do not have to have an exact cubiodal shape. Simple cuboidal epithelia is found on the surface of ovaries, the lining of nephrons, the...

Painting of birdhouse bottle.Ornamental and versatile gourd that is easily dried for either birdhouses or other craft and decorating projects. Size: 12-18" tall x 6-10" diameter. Easy to grow and may be trellised. These are the same that we grow, dry, and sell every year. Gourds are close...

Vector Generated Image of Chemiosmosis involves more than the single enzyme of substrate-level phosphorylation. Enzymes in chemiosmotic synthesis are arranged in an electron transport chain that is embedded in a membrane. In eukaryotes this membrane is in either the chloroplast or mitochondrion....

Painting of pumpkins,Pumpkin is a gourd-like squash of the genus Cucurbita and the family Cucurbitaceae (which also includes gourds).Pumpkins are grown all around the world .chemical compounds found in pumpkin promote regeneration of damaged pancreatic cells, resulting in increased bloodstream...

The word plumber dates from the Roman Empire. In Roman times, some roofs were made of lead, or plumbum in Latin. Lead roofs were waterproof, and the workers on such roofs were what are now called "plumbers".

Vector Generated Image of Henle's loop:In the kidney, the loop of Henle (or Henle's loop or ansa nephroni) is the portion of the nephron that leads from the proximal convoluted tubule to the distal convoluted tubule. The loop has a hairpin bend in the renal medulla. The main function of...
