TIPS AND TRICKS

The UV lamp

This little flashlight will be one of the most

important components in your kit, because its

light can make materials glow with

luminescence. In addition to a little visible light,

it mainly emits invisible ultraviolet light, or UV

light for short.

When the experiment

requires the UV lamp,

you will see this

picture in the

instruction manual.

To make it work, you will need a 1.5-volt

battery (AAA, or type LR03) and a small

Phillips head screwdriver.

How to insert the battery:

1. Use a

screwdriver

to loosen

the four

little screws

underneath

the lamp

and lift off

the lid.

2. Insert the battery into the battery

compartment in the correct polarity direction

and screw the lid back on again.

The test tubes

The test tubes are used as mixing and reaction

vessels. You can close a test tube securely by

turning and pushing in on the blue lid with the

built-in spoon until it hits the stop. When you

open the lid, be sure not to pull it off with a jerk,

because the liquid inside could spray

(particularly from the spoon). If you want to

shake a liquid inside the test tube, it is

important not to let the lid come loose.

Therefore, be sure to hold your thumb over the

stopper as shown in the illustration.

The double-headed measuring spoon

Use the double-headed measuring spoon to

remove chemicals from the chemical vials and

measure them out. The indication “1 large

spoon” means you should use the large end,

while “1 small spoon” means to use the small

end, with the scoop completely full in each

case.

Rinse and dry the double-headed measuring

spoon after each use, so you don’t contaminate

other chemicals.
