Accuracy

The degree to which a measurement or calculation reflects the true value.

Precision

The consistency of repeated measurements, regardless of their accuracy.

Laboratory Techniques

Practices that ensure valid and accurate experimental results, including proper handling of equipment and samples.

Calibration

The process of adjusting an instrument to ensure its measurements are accurate.

Meniscus

The curve at the surface of a liquid in response to its container, which must be read at eye level to avoid parallax error.

Dilution

The process of reducing the concentration of a solute in a solution.

Serial Dilution

A stepwise dilution of a substance in solution, often used in microbiology and biochemistry to reduce concentration.

Titration

A laboratory method used to determine the concentration of an unknown solution by adding a known solution until a reaction is complete.

pH

A measure of the acidity or basicity of a solution, represented on a scale from 0 to 14.

WHMIS

Workplace Hazardous Materials Information System, designed to communicate hazardous materials information.

Standard Solutions

A solution with a known concentration used as a reference in quantitative analysis.

Root Cause Analysis (RCA)

A systematic process for identifying the underlying cause of problems.

Error Types

Systematic error, random error, and blunder, each affecting measurement results differently.

Glassware Markings

Indications on scientific glassware (like 'A' and 'B') that denote the quality and accuracy of the glass.

Volumetric Flask

A type of lab glassware calibrated to contain a precise volume at a given temperature.

Beer's Law

A principle in spectrophotometry that relates the absorbance of a solution to its concentration.

5S Method

A Lean management tool aimed at organizing workplaces effectively through Sort, Set in order, Shine, Standardize, Sustain.

Lot Numbers

Identifiers assigned to a batch of products for tracking and quality control purposes.
