Hanging drop preparations can be observed for a long time because they do not dry up very quickly. Thus, motility of an organisim can be observed.
What else can I help you with?
Why isn't the oil immersion lens used in hanging drop procedure?
the hanging drop procedure uses a thicker slide, which could crack if the oil immersion lens is used. My bio professor worte: hanging drop slides asre too thick to use under oil.
Does hanging drop technique have any practical value?

What is the value of a hanging-drop preparation?
A hanging-drop preparation is used in microbiology to observe the motility of microorganisms. By placing a drop of liquid culture on a coverslip inverted over a concave slide, the microorganisms are suspended in a hanging drop of liquid, allowing for easy observation under a microscope.
Can the hanging drop slide be used to examine other microorganisms?
Yes, the hanging drop slide can be used to examine a variety of microorganisms, not just bacteria. It can also be used to observe fungi, algae, and other small organisms by placing a sample in the hanging drop and observing their motility or characteristics under a microscope.
Purpose of the hanging drop.?
The hanging drop method is used in microbiology to grow and observe bacterial or yeast cultures. It involves suspending a drop of liquid culture from a coverslip over a depression slide. This setup allows for the observation of microbial growth in a controlled environment.
What is the silver line in hanging drop method?
The sliver line that you see is actually an artifact and the edge of the drop.
How does hanging cause?
Hanging as a form of capital punishment is achieved by the drop and the neck is broken. Lynching some one chokes them to death.
What is the Motion of pseudomonas fluorescens in hanging drop preparation?
In a hanging drop preparation, Pseudomonas fluorescens can exhibit motility by moving actively through the liquid medium using flagella. The movement is typically characterized by a swift and smooth motion, allowing the bacteria to explore their environment efficiently within the hanging drop.
Does the hanging-drop technique have any practical value?
Yes, the hanging-drop technique is commonly used in laboratories for observing live cells or microorganisms under a microscope. It allows for the visualization of cellular behaviors and interactions in a controlled environment, making it a valuable tool in studying cell biology, microbiology, and drug discovery.
Would you expect Brownian motion to increase the longer you observe a hanging drop preparation?
Just by the sheer fact that any vibration of any kind can be considered Brownian motion for a hanging drop test. the longer you observe your bacteria, the more chance there are of Brownian motion interfering with your motility test ( I assume you're talking about the motility hanging drop, right?). It is because of this fact that the hanging drop test is quickly falling out of favor for more secure tests for motility, the semi-solid media being one of them.
How does hanging cause death?
Hanging as a form of capital punishment is achieved by the drop and the neck is broken. Lynching some one chokes them to death.
Hanging drop slide?
To make a hanging drop slide, you will need: -a depression slide -a square coverslip -some petrolatum -the liquid suspension of what you wish to view Place a small spot of petrolatum on each of the 4 corners of the coverslip. Place a drop of your suspension in the center of the coverslip. Invert a depression slide over the drop, allowing the petrolatum to attach the coverslip to the depression slide. Quickly (but carefully) invert the slide so that the coverslip is oriented "up", and the drop is hanging into the slide depression.
