Clear Borosilicate Bottle Flat Bottom Glass Test Tubes With Top

General description

A tube, conjointly called a culture tube or sample tube, could be a common piece of laboratory tableware consisting of a finger-like length of glass or clear plastic conduit, open at the highest, typically with a rounded formed bottom.
A large tube specifically for boiling liquids is termed a boiling tube.
Test tubes square measure out there in a very multitude of lengths and widths, generally from ten to twenty millimeter wide and fifty to two hundred millimeter long.

The top usually options a flaring lip to assist gushing out the contents; some sources contemplate that the presence of a lip is what distinguishes a tube from a culture tube.

A tube has either a flat bottom, a spherical bottom, or a conelike bottom. Some take a look at tubes square measure created to simply accept a ground glass stopper or a screw cap. they're usually given alittle ground glass or white glaze space close to the highest for labelling with a pencil.

We can produce any sizes according to request.

Application

Test tubes square measure wide employed by chemists to carry, mix, or heat little quantities of solid or liquid chemicals, particularly for qualitative experiments and assays. Their spherical bottom and straight sides minimize mass loss once gushing, build them easier to wash, and permit convenient observation of the contents. The long, slender neck slows down the spreading of vapours and gases to the surroundings.
A tube crammed with water and upturned into a water-filled beaker is usually wont to capture gases, e.g. in electrolysis demonstrations.
Culture tubes square measure usually utilized in biology for handling and culturing all types of live organisms, like molds, bacteria, seedlings, plant cuttings, etc.; and in medication and forensics to store samples of blood or different fluids.
A tube with a stopper is usually used for temporary storage of chemical or biological samples.
Test tubes square measure typically command in special-purpose racks, clamps, or tongs. Some racks for culture tubes square measure designed to carry the tubes in a very nearly horizontal position, thus on maximize the surface of the substance within.
Test tubes square measure generally place to casual uses outside of laboratory environments, e.g. as flower vases, tableware certainly weak shots, or containers for spices.
Where giant numbers of tests square measure run or solely little amounts square measure out there for testing, or both, microtiter plates square measure usually used as little take a look at tubes.
