Lab 1: Basic Molecular Techniques, Accuracy, and Precision

Vocabulary flashcards based on the lab objectives and techniques discussed in the lecture.

Metric Units

Standard units of measurement used in scientific contexts, including liters, milliliters, and microliters for liquid measurement.

Volumetric Instruments

Tools used to measure liquid volumes accurately, including beakers, graduated cylinders, standard pipettes, and micropipettes.

Top-loading Balance

An electronic device used for weighing, providing high sensitivity to measure masses down to one milligram.

Conversion

The process of changing a measurement from one unit to another, such as liters to milliliters.

Aspirate

To draw liquid into a pipette tip using a control button.

Zeroing

The act of calibrating a balance by setting it to zero to measure the weight of only the substance placed on it.

Micropipette

A precision instrument used for transferring small volumes of liquid, typically ranging from 0.1µl to 1000µl depending on the model.

Accuracy

The degree to which a measured value conforms to the actual (true) value.

Precision

The degree to which repeated measurements under unchanged conditions show the same results.

Weigh Boat

A shallow container used to hold a substance while weighing to prevent liquid from damaging the balance.
