What is the purpose of hanging drop technique?
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 advantages does hanging drop preparation have over a wet mount preparation?
Hanging drop slide is more resistant to evaporation because of the concave depression of the slide placed over the cells along with the petroleum jelly prevents drying. Wet mounts can dry out fairly quickly.
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.
What will you do if you drop a sodium metal to the skin of your classmates?
Immediately absorbed sodium in a cloth or tissue paper also dry the skin with tissue paper and rub gently any cold cream or petrolium jelly on the skin.
Difference between hemoglobinometer and tallquist method?
The Tallquist method simply involves comparing the color of a drop of blood on white blotting paper to the color chart provided. The Hemoglobinometer is any of several types of instruments designed to measure the percentage of hemoglobin in a blood sample.
Why is petroleum jelly used in the hanging-drop procedure?
Petroleum jelly is used in the hang drop procedure because , it reduces the evaporation of the drops of fuild . ---------------------- ALSO, this type of sealing material is used primarily to not only reduce evaporation of liquid but to eliminate air current in the preparation as well.
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 are the disadvantages to the hanging drop method?
Lol lol lol molloy students lol!

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.

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.

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.
Purpose of the hanging drop.?
A hanging-drop is used to determine bacterial motility, besides brownian movement.
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.
What is the method of supplying water drop by drop to the plants?
This is an economical and modern method of irrigation in agriculture.
