clay triangle
used to evaporate excess solvents like water
evaporating dish
suppports iron ring when heating substances or mixtures in a flask or beaker
iron stand
used to hold laboratory glassware and other equipment in place
iron ring
used for the separation of fluids, gas or liquid based on density
centrifuge
used for mincing, grinding and mixing substances
mortar and pestle
used to separate immiscible liquids
seperatory funnel
measures temperature
thermometer
used for mixing chemicals and solutions
stirring rod
used to perform reaction on small quantity of chemicals
spot plate
used to hold multiple test tubes upright
test tube rack
used for melting point determination
Thiele tube
used for rinsing various pieces of lab glasswares
wash bottle
used to incubate samples at constant temperature over a period of time
water bath
used for collecting gases
water trough
A sheet of thin metal that is used to protect
the glassware during the heating process.
wire gauze
distillation set up
distilling flask, a condenser and an adaptor
chemical process used to separate liquids from nonvolatile solids
distillation
places where scientists and medical professionals
conduct studies or perform other work relevant to their fields.
laboratory
It is an instrument used to measure mass very precisely. The device has reading
error of +/- 0.05 gram.
triple beam balance
class of balance designed to measure small mass in the sub milligram range
Analytical balance
A type of gas burner, commonly used in chemical
laboratories, with which a very hot, practically
nonluminous flame is obtained by allowing air to
enter at the base and mix with the gas.
Bunsen burner
ability to heat the sample without
any exposed flames
Hot plate
A sheet of thin metal that is used to protect
the glassware during the heating process.
Wire gauze
Used as base to hold the wire gauze
and any other container to be
heated.
Iron ring
Used to hold the test tube, distilling
flask, and other apparatus to be
heated.
Iron clamp
Supports the iron ring and iron
clamp during heating, distillation,
and other extraction purposes.
Iron ring
Supports the crucible on an iron ring when heating.
Clay triangle
A tool used to hold hot materials
or apparatus.
Crucible tong
A heat resistant container with cover in
which ores or materials are melted.
Crucible and cover
A shallow heat resistant porcelain dish in
which a solution is heated and allowed to evaporate leaving a residue on its plate.
Evaporating dish
least accurate instrument for
measuring volume
Beakers
used to precisely measure the
volume of liquids
Graduated cylinder
Used to measure a single
predetermined volume.
Volumetric flask
used to measure approximate
volumes, mixing, and sample
storage
Erlenmeyer flask
used to measure a volume of liquid that is
being transferred to another container.
Pipette
Used in quantitative chemical analysis to measure the volume of a liquid or a gas.
Burette
Used to move a small amounts of liquid
from one place to another.
Dropper
Used for moving small amounts of
solid from one place to another
Spatula
Used to mix, store or heat small amount
of substances.
Test tube
Used to aid in the transfer of liquid
from one vessel to another.
