Study Notes
Laboratory Incubators
- A laboratory incubator is a heated, insulated box used to grow and maintain microbiological or cell cultures, maintaining optimal temperature, humidity, and gaseous content of the atmosphere inside.
- Uses of incubators include bacterial growth, cell growth, and fungal growth.
- There are three types of incubators: Ordinary Incubator, CO2 Incubator, and Shaker Incubator.
Laboratory Ovens
- A laboratory oven is widely used to sterilize, dry, and heat equipment and materials in a laboratory.
- Uses of ovens include drying or dehydrating samples, sterilizing materials (including metal and glass), and evaporating excess solvent.
- There are two types of laboratory ovens: Mechanical Ovens (which circulate air throughout the chamber) and Vacuum Ovens (used for drying or dehydrating samples under vacuum).
Laboratory Water Baths
- A laboratory water bath is made from a container filled with heated water, used to incubate samples in water at a constant temperature over a long period.
- There are three types of water baths: Circulating Water Baths, Non-Circulating Water Baths, and Shaking Water Baths.
