• Your teacher has put equipment around the room. Can you:-
• Describe it• Identify what it might be used for
• Record in your booklet

Beaker
Beakers hold solids or liquids that will not release gases when reacted or are unlikely to splatter if stirred or heated.
![Page 6: Lesson 5 Lab equipment. Starter What is this and what do you think its used for?](https://reader036.fdocuments.in/reader036/viewer/2022081519/56649ebd5503460f94bc6e6e/html5/thumbnails/6.jpg)
Erlenmeyer Flask (Conical flask)
Erlenmeyer flasks (conical flasks) hold solids or liquids that may release gases during a reaction or that are likely to splatter if stirred or heated.

Round bottom Flask
Rarely used in first year chemistry, it is used for the mixing of chemicals. Narrow neck prevents splash exposure.

Test Tube Holder
A test tube holder is useful for holding a test tube which is too hot to handle.
![Page 11: Lesson 5 Lab equipment. Starter What is this and what do you think its used for?](https://reader036.fdocuments.in/reader036/viewer/2022081519/56649ebd5503460f94bc6e6e/html5/thumbnails/11.jpg)
Test Tube BrushesTest tube brushes are used to clean test tubes and graduated cylinders.
Forcing a large brush into a small test tube will often break the tube.
