Laboratory heating equipment covers the instruments that warm, melt, incubate, or sterilize samples and media in a microbiology laboratory. Each one delivers heat differently.
A hot plate gives high, direct, dry heat; a water bath gives gentle, even, wet heat up to about 100°C; a Bunsen burner gives an open flame for rapid, very high heat; an incubator holds cultures at a steady temperature over hours or days; and a dry bath heats small tubes without water. Choosing the right one depends on the temperature you need, how precise it must be, and whether the sample can tolerate direct or open-flame heat.
The articles below cover each piece of heating equipment in detail, including its parts, working principle, uses, and the mistakes that most often go wrong at the bench.
How a laboratory hot plate works, its parts and types, when to use a hot plate versus a Bunsen burner, magnetic stirrer, or water bath, and the mistakes that scorch media and crack...
How a laboratory water bath works, its parts and types, the exact temperatures that matter (37°C, 44-45°C for tempering agar, 56°C for inactivating complement), and when to use it...
How a microincinerator sterilizes a loop without an open flame, how long to hold and cool it, and why it is the required choice inside a biosafety cabinet.
Which Bunsen flame to use, how it actually keeps your work aseptic (and how little it sterilizes), and why a naked flame must never go inside a biosafety cabinet.
How a hot air oven sterilizes by dry heat: its parts, forced-air vs static-air types, the correct time-temperature cycles, how to load and wrap glassware, and why you must let it c...
