The
function of a bunsen burner is to heat substances. The burner can be regulated by changing the air and gas
mixture.
Function of the
Tripod stand For supporting apparatus during heating.
a boiling tube is
used for containing or heating small amounts of substances
Generally they're used as boiling flasks. Sometimes they're
used in vacuum systems because the spherical shape makes them stronger and less
likely to implode than a flat-bottomed flask.
A burette, or buret, is a uniform-bore glass tube with fine
gradations and a stopcock at the bottom, used especially in laboratory
procedures for accurate fluid dispensing and measurement.The burette is commonly used in titrations to measure
precisely how much liquid is used.
a conical flask is used to hold chemicals and to make your
chemical
Test tubes are widely used by chemists to hold,
mix, or heat small quantities of solid or liquid chemicals, especially for
qualitative experiments and assays. Their round bottom and straight sides
minimize mass loss when pouring, make them easier to clean, and allow
convenient monitoring of the contents. The long, narrow neck slows down the
spreading of vapors and gases to the environment.
A test tube filled with water and
upturned into a water-filled beaker is often used to capture gases, e.g. in electrolysis
demonstrations.Culture tubes are often used in biology for
handling and culturing all kinds of live organisms,
such as molds, bacteria, seedlings, plant cuttings, etc.; and in medicine and forensics to
store samples of blood
or other fluids.A test tube with a stopper
is often used for temporary storage of chemical or biological samples.Test tubes are usually held in
special-purpose racks, clamps, or tongs. Some racks for culture
tubes are designed to hold the tubes in a nearly horizontal position, so as to
maximize the surface of the culture
medium inside.Test tubes are sometimes put to
casual uses outside of lab environments, e.g. as flower
vases or containers for spices.
It is
used for holding or supporting apparatus during experiments.
A
beaker is a container holds the liquid chemicals and it can measures the volume
or amount of liquid that is put in the beaker.
It is
to measure terds to specific amounts
to be used in the scientific experiments.
it is to hold different types of chemicals together
to mix them.
Pipettes are
devices that allow the users to extract or deliver small amounts of a liquid.
