The watch glass may contain small amounts of solid or liquid samples.
The glass with measurements that is attached to a pipette is called a graduated cylinder.
An absorption pipette is a glass apparatus used in the absorption of gases.

A pipette is used to accurately measure the volume of a liquid in the laboratory. In the school laboratory the pipette is usually a glass bulb with a glass tube on either end. There is a line on the tube to indicate how high to fill the pipette to measure the required volume.
A pipette bulb is the rounded part of a pipette which you squeeze the air out of, then release to draw liquid into the pipette. If you are using a calibrated glass pipette, it will be a separate piece made of rubber which is fitted to the pipette. If it is a simple plastic pipette then the bulb will be made of the same semi-transparent plastic, and the pipette will all be one piece.
The purpose of a dropper pipette is to administer only a small drop of a liquid to something. The dropper pipette is a tool that will allow you to squeeze a single drop of the liquid it contains.
A glass or plastic pipette with a rubber bulb that is used to drop medicines into the eye.
A pipette is a glass or plastic dropper; it comes in a range of sizes between ·5 μL and 50 mL. The sides can be graduated for precise and accurate introduction of fluid reagents.
The glassware that provides the most accurate measurement of volume is the measuring cup. A glass measuring cup has lines on it to give an accurate reading.
A pipette typically looks like a long glass or plastic tube with a tapered tip and a squeezable bulb or plunger at one end. It is used to accurately transfer small volumes of liquid from one container to another. By squeezing the bulb or plunger and then releasing it, a specific volume of liquid can be drawn up into the pipette or dispensed out of it.
Pipettes are typically made out of glass or plastic. Glass pipettes are more durable and can be autoclaved for sterilization, while plastic pipettes are disposable and offer versatility in design for different applications. Both materials are suitable for accurate and precise liquid handling in laboratories.
The most simple pipette is a tube of plastic or glass having a tip with a small hole, used to transfer liquids. Now, many more complicated types of pipettes are used. See the link below for details.
