Introduction to Laboratory Equipment

Microscope A microscope is an essential tool for scientists. It is a combination of staining and light. Microscopes are used in viewing specimens that are too small that they cannot be seen by the naked eye. Types of microscopes include optical microscope, fluorescence microscope, scanning probe microscopes, and electron microscopes. Figure 1 shows a microscope. […]

Microbiological Examination of Food Sample

Introduction Microbiological examination of foods are carried out to identify and restrict harmful microrganisms which cause spoilage in foods, and ensure safety from foodborne diseases; although microbiological examinations do not determine absolute safety from pathogens because tests are done on samples, which are just a portion from the food products. Several Methods can be used

Aseptic Technique

Introduction Aseptic technique is used for several procedures by microbiologists. These procedures include transferring cultures, inoculating media, isolation of pure cultures, and for performing microbiological tests. Thus, this experiment is a very important one which serves as basics for other microbiology procedures. Aseptic techniques involves using procedures to prevent contamination from pathogens. During aseptic technic,

Safety Guidelines in the Laboratory

Introduction A laboratory poses potential risks due to exposure to corrosive and toxic materials, flammable solvents, high pressure gases, explosive chemicals and dangerous microbes. A little care and adherence to prescribed safety guidelines will help avoid laboratory mishaps. Safety goggles, protective wears, gloves, shoes, helmet, and other Personal Protective Equipments (PPEs) should be used when necessary
