The purpose of the hanging drop technique is a method in which a drop of bacterial suspension is enclosed in an air-tight chamber prepared in a special depression slide. It allows you to view living organisms.

What is the purpose to using the pinky technique?
The purpose is to hold the cap of the test tube without sitting it down, which will contaminate it.
What happens when a drop remains hanging from the tip of the burette after the solution has been added to the flask?
If there are any drops still hanging on the burette, they should be washed into the flask with distilled water.
Why is petroleum jelly used in hanging drop method?
This type of sealing material is used primarily to reduce evaporation of liquid and to eliminate air current in the preparation.
What is the purpose of a dropper pipette?
The purpose of a dropper pipette is to administer only a small drop of a liquid to something. The dropper pipette is a tool that will allow you to squeeze a single drop of the liquid it contains.
Where is the purpose of irons and grate in a fireplace?
They provide a raised spot for the fire, letting ashes drop below, and providing air circulation for the wood to burn.

Purpose of the hanging drop.?
A hanging-drop is used to determine bacterial motility, besides brownian movement.
Definition of hanging drop technique?
First you have to understand that the purpose of this technique is to observe living bacteria being motile. Motility is an inheritable phenotype and is critical for identification and classification of bacteria. The technique is done by applyling petroleum jelly to all sides of a cover glass. Add a water droplet and specimen using an aseptic loop onto the concave side of a depression slide. Put the jelly side of the cover glass over the droplet. View the droplet as it is suspended or "hanging" from the side. It is a "hanging drop" slide because the droplet remains untouched due to the concave shape of the cover glass and it just hangs from the cover glass.

What is the value of a hanging-drop preparation?
Hanging drop preparation is very valuable as it allows for a truer research capability. Hanging drop preparation offers longer observation abilities.
What is the purpose of drag and drop?
The 'drag and drop' technique saves users time. Without this technique, you'd have to use DOS Commands at a DOS Prompt (C:/ as one example) to move, copy, or delete files. With drag and drop, move is made simple between two locations the user can see.
What is the best technique to kiss?
the technique depends on kiss purpose
What is the use of hanging drop?
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.
Aside from motility what facts learned from hanging drop preparation?
The hanging drop preparation can study the motility over a longer period of time, but it is more difficult to examine than a wet mount. Wet mount is preferable to a hanging drop slide when using phase contrast optics.
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.
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.
What is the purpose of the broken colour technique?
