"tube+coolers"

Investigate the relationship between the speed of a fluid and its pressure

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.

Illustrate how spectral patterns can be analyzed from a combination of gases.

Demonstrate the free-fall motion of objects in atmospheric pressure and vacuum conditions.

Mounted on a wooden stand with a scale, the apparatus is comprised of a three-limbed glass tube with rubber tubing on the center.

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.

Extra long, flexible delivery tube for better reach and aim when dispensing liquids.

Used to investigate wavelength in air.

A Must-Have Drawing Station Accessory.

For identification of Gram-negative bacteria based on dextrose, lactose, and sucrose fermentation, and hydrogen sulfide production.

Single burette/tube clamp made of high-strength alloy, equipped with spring-loaded jaws, has a width capacity of ⁷/₈", holds burettes up to 100 ml, and fits maximum rod diameter of 16 mm.

Nylon bristles, 27 cm.

QBC STAR* Tube contains staining reagents on the inside of the tube, as well as a precision plastic float designed to separate the white blood cell layers to achieve the dry hematology technology breakthrough, bag 20

For the differentiation of members of the Enterobacteriacaea based on H₂S production, indole production, and motility.

Demonstrate the classic free fall experiment in a vacuum.

Full range of sizes to fit tubing from 3 to 12 mm (⅛ to ½") I.D.
