The document provides an overview of various types of lab glassware, including beakers, flasks, test tubes, and watch glasses, detailing their size, function, and usage in laboratory settings. Beakers are used for holding and pouring liquids, flasks are designed for swirling contents, test tubes are for storing and mixing chemicals, and watch glasses serve for small volumes requiring a larger surface area. Additional information and purchasing options for laboratory equipment are available at the specified website.

AND ITS USES

2. LAB GLASSWARE FOR QUALITATIVE USE
Beakers
Flasks
Test tubes
Watch Glass

3. BEAKERS
• Beakers are simple cylindrical
containers, in sizes from 10 ml
to 4000 ml. One of the
commonest glass
equipment found in labs, they
are used for holding solids and
liquids, and for pouring and
decanting liquids.

4. FLASKS
• Flasks are used when you want
to swirl contents without
spilling. They are fitted with
stoppers. An Erlenmeyer flask
has a flat bottom, so used for
direct heating while a Florence
flask can have either a round or
a flat bottom and can be used
for direct heating as well with a
heating mantle

5. TEST TUBES
• Test tubes are relatively smaller
than beakers, test tubes are
cylindrical lab equipment used to
store, mix and heat chemicals.
They are useful in observational
procedures.

6. WATCH GLASS
• This is a glass container which is
used when the volume of liquid is
small, but you need a higher surface
area. It is good for crystallizing and
evaporation and can also be used as
a beaker.
