If you are talking about heating the agar before using it, then you are not talking about making the agar from scratch. You are talking about agar that has already been prepared and has been allowed to solidify in a flask. Heating is necessary because the agar must go from its solid state to a liquid state so that it can bePOURED into a tube where it can solidify inside of the slanted position of the tube.

In microbiology what is the primary use of slants?
Slants are primarily used in microbiology to provide a larger surface area for microbial growth compared to agar deeps or plates. They are commonly used for the maintenance and storage of microorganisms, as well as for the evaluation of motility and oxygen requirements of bacteria.
What are the two narrow tubes in the kidneys called?
The two narrow tubes in the kidneys are called ureters. They carry urine from the kidneys to the bladder for storage before it is eliminated from the body.
What are the different types of tubes used for blood collection?
The different types of tubes used for blood collection include serum tubes, plasma tubes, anticoagulant tubes, and specialized tubes for specific tests.
Use of agar slant?
An agar slant is when a test tube is filled with liquid agar and allowed to cool and harden at an angle (slant). Agar is mixed with other nutrients to provide a medium for which bacteria can grow on.
What is the uses of Pasteur pipette?
A Pasteur pipette is commonly used in laboratories to transfer small amounts of liquid. It is useful for adding precise volumes of liquids, such as reagents or samples, to test tubes or other containers. The pipette allows for controlled and accurate dispensing of liquid.
Does a test tube hold more liquid than a flask?
It depends on the size of the test tube and the flask. Generally, test tubes have a smaller volume capacity compared to flasks. However, there are larger test tubes that can hold more liquid than smaller flasks.
To perform a reaction with small amounts of materials one should use a(n?
Graduated cylinders that are kind of red Volumetric Flask

What is the main advantage of the urea disk over both broth tubes and slants with respect to the detection or urease?
The main advantage of the urea disk test over broth tubes and slants for detecting urease activity is that it provides a rapid and visual color change result. Urea agar contains a pH indicator that changes color in response to urease activity, allowing for quick determination of urease production without the need for additional reagents or time-consuming procedures.

Do you have to label tubes before or after venepuncture?
After.
Do you have to remove IUD before tied your tubes?
There is no need to remove the IUD before (or after) having your tubes tied. Leaving it in will ensure continuous protection.
How to make hydrochloric acid?
Warning: This experiment releases toxic hydrogen chloride gas. This experiment must be done in a fumehood or outside. The containers must be glass to withstand the acid. Chemicals: conc. sulfuric acid,sodium chloride,distilled water Equipment: Round bottomed flask,funnel,test tube,bunsen burner, tripod, gauze mat, stopper with hole in the middle, 3 tubes, 3 1-inch length flexible rubber tubes, stand METHOD hold the round bottomed flask with the stand. Pour the sulfuric acid and sodium chloride in the round bottomed flask. Quickly place the stopper in the neck of the flask. Connect the 3 glass tubes and the 3 rubber tubes into a U-shape. connect one end to the stopper and the other in the water. Heat the water with the Bunsen burner and wait about a hour. NOTE Before you start the experiment you should connect the 3 tubes and the 3 rubber tubes first before you pour the acid and sodium chloride in (unless you are a CRAZY SCIENTIST)! --------- Hydrochloric acid is only the solution of hydrogen chloride in water. For the industrial production of hydrogen chloride see the link below.

Will the size of culture tubes affect am experiment's results?
The size of the culture tubes selected will depend on:The type of experimentWhat is being cultured in them and for how longCertain experiments involve growing bacteria in tubes inlaid with agar. These are called agar slants. Small volumes are required for experiments. If however, plant cells or tissues are being grown, then there should be enough space available for growth. Also, the size of the tubes determines how much gases (like oxygen and carbon dioxide) are available to the growing tissues and therefore might have an effect on the results.
What is a piece of cork?
Rubber corks are commonly used in labs with test tubes as a stopper. The rubber corks are used on flask as well. The function of the rubber cork is to keep the contents in the container.
How can you separate mixture of sugar and liquid?
Heat till the liquid boils, if you just want the sugar. If you want both, perform simple distillation, you must put the sugar in a flask, put a flame under the flask, and attach a tube to the flask (must have an airtight fit). Then attach a liebig condenser to the tube, and a receiving tube to the end of the liebig condenser. Have a flask under the receiving tube to collect the liquid. What will happen, as you heat the mixture is: all the liquid will evaporate, go along the tubes, and condense at the liebig condenser back into liquid, and it will dribble into a flask. The sugar will be left in the original flask. Getting both of them is more complicated than getting just the sugar :)
