    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
      • Fungal growth
    • Types of incubators include:
      • Ordinary Incubator
      • CO2 Incubator
      • Shaker Incubator

    Laboratory Ovens

    • Laboratory ovens are widely used in medical laboratories to sterilize, dry, and heat equipment and materials.
    • Uses of ovens include:
      • Drying or dehydrating samples by removing moisture
      • Sterilizing samples by removing or destroying bacteria or microorganisms
      • Evaporating excess solvent
    • Types of laboratory ovens include:
      • Mechanical Ovens, which circulate air throughout the chamber
      • 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
      • Shaking water baths
