A machine that uses high heat and pressure to sterilize materials by denaturing proteins.

A device that uses high temperatures (180°C) to sterilize dry materials by oxidation.

A machine that controls the temperature and humidity required to grow and maintain cultures.

A machine that spins samples at high speeds, separating them based on density.

A specialized workspace that provides a barrier between the user and potentially hazardous materials.

The ability of a microscope to distinguish two closely spaced objects as separate entities. It is determined by the wavelength of light used and the numerical aperture of the objective lens.

A viscous liquid, typically an oil, that is applied to the slide and lens at high magnification (100x) to enhance light passage and improve image quality.

The bending of light as it passes from one medium to another. This effect can distort the image.

A specialized lens designed to be used with immersion oil, offering higher magnification and resolving power.

The property of a substance that determines how much light it bends. This value is similar for oil and glass, enabling better clarity and clarity at high magnification.
