Unit 1 and 2 Aseptic Techniques and Solutions Review

Vocabulary flashcards covering aseptic techniques, micropipette parts, and solution concepts from Biotechnology Units 1 and 2.

Aseptic technique

A set of laboratory practices designed to prevent contamination from unwanted microorganisms during procedures.

Sterile technique

A lab procedure aimed at eliminating all living microorganisms and spores from tools and environments, contrasted with aseptic technique.

Ejector

A component of a micropipette that releases the disposable tip after liquid delivery.

Grip

The section of a micropipette designed to be held securely in the user's hand.

Tip cone

The end part of a micropipette onto which disposable pipette tips are attached.

Plunger

The top mechanism of a micropipette pressed down to draw up and dispense precise volumes of liquid.

Display

The window on a micropipette that shows the exact volume set for liquid transfer.

Solute

The component in a solution that is dissolved by a solvent.

Solvent

The substance that dissolves the solute to form a solution.

Aqueous solution

A chemical solution in which water serves as the solvent.

Molarity

A measure of concentration defined as moles of solute per liter of solution, used to calculate volume, moles, or concentration.

Beer's law

A principle establishing the direct relationship between light absorption and the concentration of a solution.

Percent composition
