DU Scientists/Biology types: help me identify lab bottles:

[CanuckAmok]

I need the official names for the kinds of Pyrex glassware commonly found in labs.

Beakers and test-tubes, I know. What'the other stuff called?

Specifically, the round-bodied bottles and conical-bodied bottles with rubber stoppers, as seen in TV shows.

1. the little test tube thingys are called cuvettes

I'm actually not sure how to spell cuvettes.

Erlenmeyer flasks
titration tubes (but I don't know if they're pyrex)

2. Erlenmeyer flasks are the conical ones...

..that are larger at the bottom and narrower at the top. Here's a useful website: Labglass.com. Go to their online catalog and you can see drawings of each item. Some other common lab items are round-bottom flasks, graduated cylinders, and separatory funnels.

3. flasks and more!

The conical bottle-like one with the neck and the rubber stopper is an Erlenmeyer flask. The rounded one with the neck and rubber stopper is a Florence flask.

Petri dish: shaped like a squat, flat tuna can. Has a lid. Used for growing cultures.

Graduated cylinder: looks like a flat-bottomed testtube attached to a base. Has volume measurements printed on the side. Used for measuring. (no duh!)

Refluxers and distillers: flasks with special necks or tops that allow you to direct distilled vapors into another vessel (distiller or retort), or to condense them and trickle the condensate back into the same vessel (refluxer).

Crucible: vessel for high heat applications.

Burets and separatory funnels: vessels with a valve at the bottom that allow you to remove the denser phase of a separated liquid mixture. Burets allow you to add a liquid to something else at a gradual, controlled rate.

Nebulizer: mixes a liquid with a current of air and turns it into a fine vapor (kind of the way an airbrush works).


There are many different kinds of all these things and more. A good labware catalogue will list 'em all, with pictures!

You mentioned television... Are you perhaps writing a screenplay or something?

4. Thanks everyone...

No script this time... I'm going to buy some of these to hold liquor in my new place. One of the things I want to do is rig-up a pair of flasks to dispense an exact measurement of two parts gin to one part vermouth through a tube with a spigot.

Yes, I'm a decedent twit.
