lab equipment Flashcards
measure the volume of a liquid. It has a narrow cylindrical shape
graduated cylinder
most frequent method for transferring liquid chemicals or solvents in the organic laboratory
syringe
represents the amount of liquid that has been measured
graduation
measure and deliver accurate
volumes of liquid
pipettes and micropipettes
measure a much smaller
volume, starting at 1 microliter
micropipette
start at 1 milliliter
pipette
used in analytical chemistry for accurate dispensing of variable, and for measuring the volume of a liquid
burette
turning the tap to allow the acid be added chuchu
perpendicular direction
at the tip of burette to control the flow of the chemical solution
stopcock and valve
glass burette
acid burette
rubber tube burette
alkali/base burette
ptfe material for burette
ptfe burette
type of laboratory flask, calibrated to contain a precise volume at a certain temperature. used for precise dilutions and preparation of standard solutions
volumetric flask
parts of beam balance
pan, riders, balance pointer, beams, base, counter weight
types of digital balance
analytical balance, top loading balance
used by chemists to handle chemicals, especially for qualitative experiments and assays
test tubes
Their spherical bottom and vertical sides reduce mass loss when pouring, make them easier to wash out, and allow convenient monitoring of the contents
test tubes
to easily clean the inside of a test tubes and other glassware
test tube brush
culture different microorganisms and cells. To study microorganisms like bacteria & viruses under great observation, it is important to keep them isolated from other species or elements.
petri dish
concave, a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance and as a cover for a beaker.
watch glass
perform reactions on a small amount of chemicals. tiny test tubes
spot plate, reaction plate, culture plate
a flat plate with multiple “wells” used as small test tubes.
microwell plate or microtiter plate
Used to hold and heat liquids, as a reaction vessel, as a hot water bath, for heating liquid mats
beaker
used as containers to hold liquids
flasks
for uniform heating, boiling, distillation and ease of swirling;
Florence flask
used to contain chemical reactions run by chemists, especially for reflux set-ups and laboratory-scale synthesis
round-bottom flask
to contain chemicals in liquid or powder form for laboratories and stored in cabinets or on shelves.
reagent bottles or media bottles
types of reagent bottles
wide-mouthed reagent bottle, narrow-mouthed reagent bottle, amber reagent bottle
to store medication as liquids, powders or capsules. They can also be used as scientific sample vessels
vials
to collect samples of liquids, which will flow up into the tubes against the effects of gravity
capillary tube
rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks.
wash bottle
the material where wash bottle is made up of
polyethylene
to grab a small item and cannot do it with your fingers
forceps
to connect other pieces of lab equipment. It can be cut, bent and stretched for a variety of uses.
glass tubing
for guiding liquid or powder into a small opening.
funnel
used in flow lines for fluids and gases in a variety of hydraulic, pneumatic, process, medical, and specialty applications.
rubber tubing
used for calculating the pH of a liquid
pH meter
it includes two vessels
calorimeter (inner and outer vessels for heat insulator)
measure the temperature of the liquid
thermometer
stir the liquid and distribute the heat in the vessel
stirrer
puts an object in rotation around a fixed axis (spins it in a circle), applying a force perpendicular to the axis of spin (outward) that can be very strong
centrifuge
where the centrifugal acceleration causes denser substances and particles to move outward in the radial direction.
sedimentation principle
used to evaporate excess solvents – most commonly water –to produce a concentrated solution or a solid precipitate of the dissolved substance.
evaporating dish
to crush up solid chemicals into smaller pieces, or to grind solids into fine powder
mortar and pestle
used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example.
magnetic stirrer
connects the condenser and the receiving flask in a distillation process
adapter
used to separate mixtures of two liquids with different boiling points
distilling flask
used in the laboratory to cool hot gases into liquids
condenser
Used with filtering flask for performing vacuum filtration.
buchner funnel
used in liquid-liquid extractions to separate the components of a mixture into two immiscible solvent phases of different densities
separatory funnel
to contain chemical compounds when heated to extremely high temperature
crucible
Used to hold crucibles when they are being heated. They usually sit on a ring stand
clay triangle
Used to hold crucibles and evaporating dishes when they are hot.
crucible tong
used to heat glassware or its contents
hot plate
used to apply heat to containers, as an alternative to other forms of heated bath
heating mantle
used for heating and exposing items to flame
burners
three-legged platform used to support flasks and beakers
tripod
placed on top of the tripod to provide a flat base for glassware
wire gauze
used to give an airtight seal to laboratory flasks and test tubes
stoppers
for cutting a hole in a cork or rubber stopper to insert glass tubing
cork borer
