Laboratory Equipment Mastery

A set of practice flashcards focusing on laboratory tools including pipettes, burettes, and funnels based on the lecture transcript.

Pipettes are used for transferring liquids with a __________ and quantity known to a high degree of accuracy.

fixed volume

__________ are calibrated in the factory to release the desired quantity of liquid.

Graduated pipette

Disposable transfer pipettes are made of __________ and are useful for transferring liquids dropwise.

plastic

__________ are devices used typically in analytical, quantitative chemistry applications for measuring liquid solution.

Burettes

Burettes differ from pipettes because the __________ delivered is changeable.

sample quantity

Graduated Burettes are used heavily in __________ experiments.

titration

In Burette and Pipette use, it is common to measure the __________.

volume delivered

The volume delivered in a titration is calculated using the formula __________.

$$V_{final} - V_{initial}$$

A __________ is scientific equipment used specifically to hold and secure a burette on a stand.

Burette clamp

Burette clamps can be made of various materials, such as plastic and __________.

cast iron

An iron clamp with a __________ to hold a burette is likely to be more durable.

rubber knob

Usually, Burette clamps come in __________, which means they can hold two burettes at once.

double

A __________ is a tube or pipe that is wide at the top and narrow at the bottom.

Funnel

Funnels are used for guiding liquid or __________ into a small opening.

powder

Pipettes are used when the quantity of liquid must be known to a high degree of __________.
