Chlamydomonas are single-celled green flagellates while Volvox is a part of colonial phytoflagellate that develops a hollow spheroid with several thousand cells enclosed in its mucilaginous wall.
can be described as an test of immunoprecipitation (immunodiffusion) test that determines what specific strain of Corynebacterium Diphtheriae is toxic.
The microbial content of the outer atmosphere is changing with the season, it contains various pollen, algae, mosses, grains, spores of fungi, ferns, bacteria, and viruses.
Pipetting Definition Pipetting is the process of using a pipettor to measure and dispense small volumes of liquid. It is a fundamental technique used in many laboratory procedures, including preparing solutions, dispensing samples for analysis, and performing various types of assays. When pipetting, the user first sets the desired volume on the pipettor by adjusting
What is Ergonomic Pipetting? Ergonomic pipetting is the design and use of laboratory pipettes in a way that reduces the risk of injury or strain to the hands and wrists of the user. Pipetting is a repetitive task that, if not done properly, can lead to discomfort and even injury over time. Ergonomic pipetting involves
Positive displacement pipettes are characterised by piston-driven displacement. The piston in a positive displacement pipette makes direct contact with the sample, which allows the aspiration force to remain constant. Air displacement pipettes accurately dispense the majority of liquids. However, the precision may be affected negatively by the solution’s viscosity, volatility, surface tension, and temperature. For
An air displacement pipette (also known as a “volumetric pipette” or “mechanical pipette”) is a type of liquid handling tool commonly used in laboratory settings. It uses air displacement to draw a specific volume of liquid into the pipette’s barrel. The volume of liquid is determined by the calibrated volume markings on the barrel of
Standard laboratory equipment for measuring and transferring minute amounts of liquid includes micropipettors. You’ll put them to use all through the semester and into subsequent upper-level courses. If you want reliable results from your tests, you must become an expert user of these tools. Objective Parts of a micropipette Different sizes of micropipettes The laboratory’s
A dry mount slide is the simplest type of slide preparation in microscopy. It is the process in which a dry specimen is placed directly on the clean glass slide without using any liquid medium. It is the air that remains between the specimen and the objective lens, and the refractive index of air is
Pseudomonas Aeruginosa Principle The MacConkey Agar is a specialized culture medium widely used in microbiology for the isolation, identification, and differentiation of gram-negative bacteria, particularly those belonging to the Enterobacteriaceae family. The principle of MacConkey Agar lies in its combination of selective and differential properties, making it an effective tool in microbiological analyses. The medium’s
