Biology lab tools

Micropipette

Precise measurement of very small volumes (0.1 µL to 1,000 µL).

Spectrophotometer

An instrument used to measure the absorbance or transmittance of a sample.

Graduated Cylinder

Accurate measurement of larger volumes (10 mL to 1 L).

Serological Pipette

Measuring volumes between 1 mL and 50 mL.

Cuvette

A small tube or container for holding samples in spectroscopic experiments.

Centrifuge/Conical Tube

For spinning down samples to concentrate or separate substances.

Beaker

General mixing and initial measurements (not precise).

Erlenmeyer Flask

For mixing solutions that need swirling without spilling.

Test Tube

Small reactions or temporary solution storage.

Micropipette Tips

Disposable tips for micropipettes to prevent contamination.

Microcentrifuge Tube

Handling small volumes (e.g., for DNA, RNA, or protein work).

Transfer Pipette

Quick, non-precise liquid transfers.

What is the appropriate tool to measure volumes less than 1 mL?

Micropipette.

What instrument is used for accurate measurement of larger volumes between 1 mL and 50 mL?

Serological pipette.

What tool would you use for general mixing and initial measurements?

Beaker.

For rapid liquid transfers, which pipette is recommended?

Transfer pipette.

When is it appropriate to use a graduated cylinder?

For volumes greater than 50 mL.

What is the primary function of a centrifuge/conical tube?

To concentrate or separate substances by spinning down samples.
