Be aware of parallax error. The bottom of the meniscus should be in line with the desired
graduation mark. When reading the volume of the liquid, your eyes should be in line with the
meniscus and to ensure that this is achieved, the measure should remain on a flat surface (e.g. on a
bench top). If it is necessary, you will be required to move your head down to the correct level. DO
NOT lift the measure to your eyes level – it will be more difficult to read accurately.

FIGURE: ENSURE YOUR EYES ARE AT THE SAME LEVEL AS THE GRADUATION MARK. (FROM CHROMACADEMY.COM)

CONTAINERS/BOTTLES
The containers for all products are available at the middle area of the lab. Please ensure that you take
a suitable container each time for your product. There are bottles for 50 mL, 100 mL and 200 mL, and
glass containers for ointments, creams, jellies and pastes with different sizes.
An amber coloured bottle is for products that should be protected from light.

A fluted bottle is for products meant for external applications.
A non-fluted bottle is for products meant for internal applications.

You would have to submit your products in these containers, along with proper labels. Your
products will be evaluated and before the next practical class, you are required to clean the
bottles/containers. Failure to do so will result in certain penalties that are deem fit by the lecturer.
