In chemistry, a retort stand, also called a clamp stand, a ring stand, or a support stand, is
a piece of scientific equipment intended to support other pieces of equipment and glassware
— for instance, burettes, test tubes and flasks.
What is a clamp used for in chemistry?
Utility clamps support your flasks, beakers, and burettes. They
stabilize your sample containers
, preventing possible breakage and sample loss.
What is the use of clamps in laboratory?
It is composed of 3 parts: 2-prong adjust, metal rod, and clamp down (attach the clamp to the ring stand for adjust the height). This apparatus is connected to a ring stand or retort stand. It is used
to hold round laboratory glassware, such as a beaker, and flasks, etc
.
What is the use of clamp stand in distillation?
Use a utility clamp
to support the boiling flask
.
This also prevents the thermowell heating source from being used as a support. If it is necessary to lower the thermowell to quickly cool the boiling flask, the thermowell can be lowered and the boiling flask remains attached to the apparatus.
What is the use of ring stand in laboratory?
: a metal stand consisting of a long upright rod attached to a heavy rectangular base that is used with
rings and clamps for supporting laboratory apparatus
.
What is the main function of burette?
Burette is a laboratory apparatus commonly
used to dispense and measure variable amounts of liquid or sometimes gas within chemical and industrial testing specially for the titration process in volumetric analysis
. Burettes can be specified according to their volume, resolution, and accuracy of dispensing.
What is the use of wash bottle in laboratory?
In the lab, wash-bottles are used
to supply precise and small quantities of various liquids
. Working with chemicals, which are sometimes dangerous, requires a high level of responsibility and concentration.
What is the function of test tube clamp?
It is
used for holding a test tube in place when the tube is hot or should not be touched
. For example, a test tube holder can be used to hold a test tube while it is being heated.
What is the use of iron clamp?
Iron clamp – An iron clamp is a piece of
laboratory equipment used to hold things
and is placed in an iron stand to elevate other equipment.
What is the difference between extension clamp to three fingered clamp?
Although in many situations the clamps can be used interchangeably, an extension clamp must be used when clamping to a round bottomed flask (Figure 1.4b), as
3-fingered clamps do not hold well.
What is the purpose of distillation?
Distillation is used
to separate liquids from nonvolatile solids
, as in the separation of alcoholic liquors from fermented materials, or in the separation of two or more liquids having different boiling points, as in the separation of gasoline, kerosene, and lubricating oil from crude oil.
Why is it called a retort stand?
The term retort comes by way of Middle French, but ultimately
from Latin retortus, twisted back, for the shape of the neck
.
What is the equipment used for distillation?
The device used in distillation, sometimes referred to as
a still
, consists at a minimum of a reboiler or pot in which the source material is heated, a condenser in which the heated vapor is cooled back to the liquid state, and a receiver in which the concentrated or purified liquid, called the distillate, is collected …
What is a beaker used for?
Beakers are useful as
a reaction container or to hold liquid or solid samples
. They are also used to catch liquids from titrations and filtrates from filtering operations. Laboratory Burners are sources of heat.
What holds a burette onto a ring stand?
Burette clamp
is a scientific equipment which used specifically to hold and secure a burette on a stand, so that a burette is fixed and more convenient for the experiment.
What is the iron stand?
:
a raised and usually ventilated metal stand on which a hot flatiron may be rested when not
in use.
