What is the difference between dry granulation and wet granulation?
Wet meaning you wet the ground first with a hose
What is wet granulation used for in the pharmaceutical industry?
Wet granulation is used to improve the flowability of the particles, increase the uniformity of the contents of the drug, unify the size of the particles, reduce the segregation of different components of the drug, and to increase the density of the material. Due to the advantages of wet granulation, it is the most common granulation method in the pharmaceutical industry.
What are the disadvantages of wet granulation?
As wet granulation requires multiple steps for extra blending, granulation, and drying, it can be time-consuming. Wet granulation is also unsuitable for water sensitive active pharmaceutical ingredients due to their incompatibilities with water. As the granule are dried in elevated temperatures, the high temperatures may lead to instability. Failure to accurately determine the endpoint of the wet granulation process may also lead to compaction and dissolution problems. The material may also stick to the walls of the machine during the process instead of being added to the granules.
What are the advantages of roller compaction over wet granulation?
Roller compaction can continuously produce tablets whereas wet granulation produces tablets in batches. Roller compaction is also simpler with fewer steps and it requires less equipment and floor space. As roller compaction requires less time and energy, it is less expensive than wet granulation.
Does wet on wet refer to the technique where fresh paint is applied onto already wet paint?
True, it does! There is also a technique in water colour where paint is added to a wet surface. This is also referred to as "wet on wet".
What are the methods of granulation?
There are two types of granulation they are Wet Granulation and Dry Granulation.Wet granulation and dry granulation depends on the type of fertilizer granulators and whether adding water during granulation.In general, Roll Extrusion Granulator(Azeus Fertilizer Machinery) is dry granulation machine. It requires moisture of raw materials less than 40% and no water added during granulation. So, it's compound fertilizer granules are also dry, in long-stick shape.But, as for New-type Granulator(organic fertilizer by Azeus Fertilizer Machinery) and Pan Granulator (both organic and compound fertilizer), with required a low moisture of raw materials, water must be add during granulation. Or, the fertilizer granulation will fail.
What is an advantage of a simple stain over a wet mount?
You can see clearer images in the simple stain technique rather than the wet mount technique...
Can you use the wet on wet technique with canvas?
Of course you can! Impressionist painters do that all the time.
What is the difference between wet granulation and dry granulation?
The dry granulation process is used to form granules without using a liquid solution because the product to be granulated may be sensitive to moisture and heatWet granulation involves the massing of a mix of dry primary powder particles using a granulating fluid (the process of adding a liquid solution to powders). The fluid contains a solvent which must be volatile so that it can be removed by drying, and be non-toxic
Why are micro organisms hard to see in wet preparations?
Why are mircoorganisms hard to see in wet preparation technique?
What technique do you use dry wet dry for?
the technique is used for breading a choice of food like a chicken breast or shrimp
Why a smear preparation is preferred compare to a wet mount?
bcoz a heat-fix smear have a good contrast than the wet mount
