Study Notes
Laboratory Incubators
- A laboratory incubator is a heated, insulated box used to grow and maintain microbiological or cell cultures.
- It maintains optimal temperature, humidity, and gaseous content of the atmosphere inside.
- Uses of incubators include bacterial growth, cell growth, and fungal growth.
- Types of incubators include 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 metal and glass, and evaporating excess solvent.
- Types of laboratory ovens include mechanical ovens, which circulate air throughout the chamber, and vacuum ovens, which are used for drying or dehydrating samples under vacuum.
Water Baths
- A water bath is laboratory equipment made from a container filled with heated water.
- It is used to incubate samples in water at a constant temperature over a long period of time.
- Types of water baths include circulating water baths, non-circulating water baths, and shaking water baths.
