00:00:00.266 --> 00:00:01.201
That is correct.

2
00:00:01.201 --> 00:00:03.303
All equipment used
should be washed properly

3
00:00:03.303 --> 00:00:06.439
before you leave the lab,
so it can be used by the next person.

4
00:00:07.207 --> 00:00:10.443
Using dirty glassware can cause unwanted
chemical reactions,

5
00:00:10.944 --> 00:00:15.181
erroneous results due to contamination,
and produce unreliable results.

6
00:00:15.682 --> 00:00:18.852
If you're not sure how to clean
your equipment, ask a demonstrator.

7
00:00:19.285 --> 00:00:21.554
Well done.
Please continue to the next hazard.
