TIPS AND TRICKS

There are some tools in your kit, such as the

chemical vials (parts no. 4-6), the lid opener

(part no. 16), the pipettes (part no. 2), the test

tubes (part no. 8), and the double-headed

measuring spoon (part no. 9), that you will be

using frequently in your experiments. You will

need the UV lamp (part no. 7) for the exciting

experiments with invisible light, and the red

film (part no. 2) will be used to make a red-light

lamp to protect against glare while performing

experiments. On this page and the next two

pages, you will learn everything you need to

know about these components!

The chemical vials

The chemical vials have a large chamber for

larger quantities and a small chamber for

chemicals that you will only need to use in

small amounts. The size of the vial is

determined by the minimum required size of the

labels. The vials are equipped with safety

closures in order to prevent small children from

getting into them.

How to open the chemical vials:

Sometimes, some of the

chemical will stick to the

inside of the lid. To prevent

any of it from falling onto

your hand or your work

surface, bang the bottom

of the vial against the

table before you open it.

The illustration shows

how to use the lid opener

to open the safety closure.

Always take just the

amount that you will need

for the experiment, and

immediately re-close the

vial.

Since the lid opener will always be needed to

open the chemical vials, it is not specifically

listed in the “You will need” sections.

The pipettes

You will use the pipettes to add liquids drop by

drop or to transfer liquids from one container to

another.

How to use the pipette:

1. Squeeze the upper part of the pipette between

thumb and index finger, and dip the tip of the

pipette into the liquid.

2. As soon as you ease up on the pressure, the

liquid will rise up the pipette.

3. By careful control of the pressure, you can

make the liquid slowly drip out again.

TIP!

This is how to use the pipette!

To clean it, fill and empty the pipette several

times with soapy water and then with plain

water, and let it dry standing up in a large

measuring cup.

The “one full pipette” quantity indication

means the amount sucked into the pipette after

one firm squeeze.
