LAB APPARATUS Flashcards
It is a common container in most labs. It is used for mixing, stirring ang heating chemicals
Beaker
It is a sheet of thin metal that has net-like crosses or a wire mesh.
Wire Gauze
It is used to clean laboratory glassware and other equipment
Wash Bottle
It is used to smooth things
Triangular File
These are used for grabbing things that should not be touched by hand
Crucible Tong and Beaker Tong
They are used in chemistry laboratories, by placing them on top of a glass or plastic tube.
Pipet Bulb or Pipettor
It is used to channel liquids or fine-grained substances into containers with a small opening
Funnel
It is a round flask with a long neck and flat bottom. It is used to measure an exact volume of liquid
Volumetric Flask
It is a glass tube that is open at the top and comes to a narrow pointed opening at the bottom
Burette or Buret
It is usually a round-bottomed flask for holding a substance to be distilled
Distilling Flask
These are small glass or plastic tubes with narrow tips on one end and a rubber bulb on the other.
Dropper
It is also known as a boiling flask
Florence Flask
They are implements used since ancient times to prepare ingredients or substances by crushing and grinding them into a fine paste or powder in the kitchen, laboratory or pharmacy
Mortar and Pestle
It is designed to transfer a specific, predetermined volume of liquid
Transfer Pipet
It is a bowl, typically made of hard wood, metal, ceramic, or hard stone, such as granite
Mortar
They resemble simple glass tubes and cannot be used to accurately measure liquid amounts less than their specified capacity
Transfer Pipet
It is a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks
Wash Bottle
The purpose of this equipment is to be placed on the support ring that is attached to the ring stand between the Bunsen burner and the beakers to support the beaker or other glassware or flasks during heating
Wire Gauze
It is a round piece of glass that is slightly concave/convex. It can hold small amount of liquid or solid
Watch Glass
It is a mechanical apparatus that is connected to a flammable gas source. Utmost safety is required when using this apparatus
Bunsen Burner
It is used for extremely accurate addition of liquid. It is one of the most accurate tools in the lab
Burette or Buret
It is known as a conical flask, it was named after its inventor in 1861
Erlenmeyer Flask
It serves as a vacuum source for filling regeants through a pipette and also help control the flow of liquid from the dropping bottle
Pipet Bulb or Pipettor
Most of this tool have spouts on their rims to aid in pouring. They also commonly have lips around their rims and markings to measure the volume they contain, although they are not a precise way to measure liquids
Beaker
It is used for measuring an exact volume of liquid and placing it into another container
Measuring Pipette
They come from a wide range of sizes
Beaker
They suck up liquid that can then be squeezed out in small drops
Dropper
It is used for pouring liquids or powder through a small opening and for holding the filter paper in filtration
Funnel
It is used to measure masses very precisely; the reading error is 0.05 gram
Triple Beam Balance
It is an accessory that can be used with a Bunsen Burner to provide a broad flat fan flame, similar to that of a fishtail burner
Wing Top/Flame Speader/Fish Tail
It is used to hold liquids and can be easily swirled and heated. It can also easily be capped by rubber or glass stoppers
Florence Flask
They come with special caps that will not let anything in or out
Volumetric Flask
It has a narrow neck and expands toward its base. It can easily be clamped to a ring stand as well as heated or shaken mechanically
Erlenmeyer Flask
It is used in tranferring liquids in small containers
Funnel
They can be used for evaporation purposes and can also function as a lid for a beaker
Watch Glass
It is often used to bend glass as it spread out the heat over a larger area, making it more uniform
Wing Top/Flame Spreader/Fish Tail
It is a shallow round dish which is used to grow culture of different organisms
Petri Dish
It is a glass or plastic cylinder used for holding hydrometers
Hydrometer Cylinder
It is a laborator apparatus resembling a pair of scissors
Utility Clamp
It is a really thin tube, usually about 1/2 mm across the inside
Capillary Tube
It is a wire and ceramic triangle used to support a crucible while it is heated over a bunsen burner
Clay Triangle
They are used to evaporate excess solvents — most commonly water — to produce a concentrated solution or a solid precipitate of the dissolved substance
Evaporating Dish
Used for measuring volumes of liquids. This piece of equipment is used routinely, although it is only moderately accurate compared to other tools, such as volumetric flasks
Graduated Cylinder
It is a small clay cup made of a material that can withstand extreme tempratures. They are used for heating substances
Crucible
This apparatus is connected to a ring stand or retort stand. It is used to hold round laboratory glassware, such as beaker, flasks, etc.
Utility Clamp
It is an airtight container which maintains an atmosphere of low humidity through the use of a suitable drying agent which occupies the bottom part
Dessicator
This type of clamp is made from stainless steel
Utility Clamp
It is used both for the cooling of heated objects and for the storage of dry objects that must not be exposed to the moisture normally present in the atmosphere
Desiccator
