A heavy Erlenmeyer flask with an inlet because that vacuum and an opening that fits a Buchner funnel. When linked to vacuum and capped with a Buchner funnel, offered to filter mixtures of solids and also liquids.


Flask, Volumetric

A ring flask with a long, thin opened bearing one mark. The mark coincides to the volume suggested on the flask. Used to prepare solutions and measure liquids really precisely.


Funnel, Buchner

A porcelain or plastic funnel include many small holes and also a rubber stopper approximately its nozzle. Provided in conjunction with a filtering flask to filter mixtures of solids and also liquids.


Funnel, buret

A funnel containing a relatively thin nozzle that fits into the peak of a buret. Supplied to supply liquids without making a mess!


Funnel, powder

A funnel containin a relatively wide nozzle. Used to provide solids there is no making a mess—essential in an accurate preparation of solid-liquid solutions.



Graduated cylinder

A thin cylinder containing plenty of markings. Supplied to measure up liquids with moderate precision.



Hot hands

Glove-like sleeve make of a rubbery and thermally insulating polymer. Used to handle hot glassware.






LabQuest data salvation device

A handheld maker that has several ports because that probes (see below) and also a USB port for a speed drive. The touchscreen is finest controlled utilizing an accompanying stylus.


LabQuest pH probe

A probe through a fragile electrode in ~ its base, provided to measure up pH of liquid solutions. Should be save in solution when not in use, and also should always remain wet during experiments. Must be calibrated utilizing buffers of well-known pH.


LabQuest press probe

A boxy probe through a Luer lock inlet, provided to measure up the press of gases. Maximum press reading of 2 atmospheres.


LabQuest spectrophotometer

A big probe v a USB cord and also slot for cuvettes. Provided to measure absorption spectra that pure liquids or liquid solutions. When used with solutions, should be calibrated through pure solvent.


LabQuest temperature probe

A thin steel probe supplied to measure up temperature that liquids or solids.




A multimeter is supplied to measure present or voltage throughout two point out in an electric circuit. Attach the black result in COM and also the red result in "VΩmA." usage the dial to adjust the amount measured and also the scale of measurement.





Pipet bulb

The pipet bulb is a blue, balloon-shaped maker made of rubbery polymer the fits top top the finish of pipets. Squeeze out the bulb, place on the end of the pipet, and also release to draw up liquid.


Pipet, Pasteur

Pasteur pipets are little glass pipets that absence markings provided to transfer little amounts of fluid and/or add liquid dropwise. Usage the tiny tan Pasteur pipet bulbs with Pasteur pipets, fairly than the big blue bulbs.


Pipet, serological

A thin cylindrical item of glass or plastic with a conical nozzle and also many markings. Supplied to provide liquids with moderate precision. Press out whole of materials when using.


Pipet, volumetric

A slim cylindrical piece of glass through a bulb close to one end and also a solitary mark. The mark synchronizes to the volume shown on the pipet. Offered to deliver liquids with really high precision. Perform not press out the last little of liquid—just enable gravity to carry out its work.




Ring stand

A stand through a vast metal base and a solitary metal rod. Clamps and also clamp holders connect to the rod.


Rubber policeman

A wedge-shaped item of rubber through an opening that fits top top the end of a glass stirring rod. Provided to fish the end goopy solids and also other stubborn buggers in the bottom that flasks.




A curved piece of steel in the form of a half-pipe v a tapered end. Supplied to deliver solids. Don"t rod it directly into a hard jar if you"re gift careful.


Spectroscope, handheld

Also called a "spectrometer," this device uses diffraction to different an incoming irradiate beam right into individual wavelengths. The be separate beams fall on a wavelength scale in nanometers, allowing one to measure the wavelengths of light in the incoming beam. Tutorial



A item of flint hosted inside a little bowl and also attached come a metal piece that can be rapidly slid throughout the flint to produce a spark. Provided to irradiate Bunsen burners.



Test tube

A tube-shaped piece of glass supplied to hold liquids and also solids because that observation. Comes in small, medium, and large sizes. Don"t fill an ext than three-quarters full if you"re being careful.





Wash bottle

A party made of versatile plastic through a thin, angled nozzle. Provided to organize liquids (usually water) for spraying or delicate delivery. Advantageous for adding that last little of liquid throughout solution ready in a volumetric flask.


Watch glass

A shallow, large piece of glass used to organize solids for drying or observation. May additionally be provided to sheathe beakers or Erlenmeyer flasks to minimization evaporative losses.


24-Well plate
