LAB

Parallax
Viewing the meniscus from different angles
graduated cylinder
measuring or mixing liquid in a chemistry laboratory
volumetric pipets
involves drawing a liquid into a pipet and allowing liquid to drain from the pipet in a controlled manner.is used to quantitatively transfer a liquid from one container to another.
burets
is a long narrow, calibrated tube with a device at one end to control the flow of liquid. It is a glass tube that is graduated and has a tap on the bottom of it. It is a vertical cylindrical shape.
volumetric flask
is a piece of laboratory glassware, a type of laboratory flask, calibrated to contain a precise volume at a particular temperature. Volumetric flasks are used for precise dilutions and preparation of standard solutions. it also involves dissolving a solid solute to make a solution of a definite volume. make sure you don’t over fill the line and aligned the meniscus with the calibration mark.
Erlenmeyer flask
is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck.
Beaker
A thin glass vessel used as container for liquids. It has a graduation for the measurement of volume. It is also used in heating liquids.
test tube
typically used for scientific experiments. They are used to contain specimens, to identify specimens, to heat and cool elements, and to mix specimens. Generally, this is a very small amount of the substance.
rubber stopper
is to prevent fluids or gas from coming out, it basically a cork for laboratory equipment. they can also be used to insert stirrers and or thermometer.
spectrophotometer
is an instrument used to study the response of solutions to light. it uses a UV-Vis light and has two scales one is to read the transmittances and other for display of absorbance and logarimithic form
