What Reagents are used in osazone test?
The reagents used in the osazone test are phenylhydrazine and acetic acid. These reagents are used to detect reducing sugars such as glucose by forming characteristic needle-like crystals called osazones.
What result would benzene have in ferrox test?
In the ferrox test, benzene would not show any result because benzene is not reactive with the reagents used in the test. The ferrox test is typically used to detect the presence of phenol or compounds with a phenolic group, which can form colored complexes with the reagents. Benzene lacks this functional group and therefore does not participate in the reaction.
What color tube used for elisa test?
For an ELISA test, typically a clear or transparent tube is used to hold the reagents and samples. The color of the tube itself doesn't affect the test results, but it should have a smooth surface to ensure accurate readings of the absorbance.
Why is semi-solid media used for the hydrogen sulfide test rather than broth culture?
Semi-solid media is used for the hydrogen sulfide test to maintain contact between the culture and the test reagents, which helps in detecting the production of hydrogen sulfide. In broth culture, the culture and reagents may not consistently come into contact due to the liquid nature of the medium, potentially leading to false negative results.
What is the practical application of Hellers test?
Heller's test, also known as the finger drop test, is used to assess grip strength. It can help in identifying weakness or paralysis in the hand and forearm muscles, often indicating nerve damage or other neurological conditions. This test is commonly used in clinical settings for diagnosing conditions like carpal tunnel syndrome or nerve injuries.
What are the reagents used in the catalase test?
hydrogen peroxide

What is the currency used in Prague called?
Crowns (koruna) and hellers, although heller coins no longer exist.
Which are reagents used for epoxide ring opening by amines?
Common reagents used for epoxide ring opening by amines include primary or secondary amines in the presence of acids like HCl or H2SO4. Other reagents include sodium azide, sodium cyanide, or lithium nitride. Catalytic systems like aluminum alkoxides or titanium alkoxides can also be utilized to facilitate the reaction.
What are the reagents of water to analyze?
Some of the reagents used in water analysis include amino acid, Ammonia 1 and Ammonia 2. These may be provided in solid, liquid or powder form depending on the type of test.
What is the reagent used to test Dnase test?
There are no reagents added when a Dnase test is performed. The test is done in a methyl green medium with a pure inoculum culture. If halos form around the culture than Dnase is present.
What are the reagents used in voges-proskauer tests?
The reagents commonly used in the Voges-Proskauer test are alpha-naphthol and 40% potassium hydroxide (KOH). These reagents are added to the bacterial culture after the addition of the Barritt's reagent (a mixture of 5% alpha-naphthol and 40% KOH) to detect the production of acetoin, which is indicative of certain bacterial species such as Enterobacter and Klebsiella.
What do you mean by reagents in chemistry?
Chemical compounds used in laboratory are frequently called reagents.
