Butanol 99.4%
- n-Butanol (1-butanol): The "n" stands for "normal," indicating that the carbon chain is linear. It is often used as a solvent and in the production of plastics, coatings, and pharmaceuticals.
- Isobutanol (2-methyl-1-propanol): This isomer has a branched structure, with a methyl group (-CH3) attached to the second carbon atom. Isobutanol has applications as a solvent, in the production of various chemicals, and as a fuel additive.
- Sec-butanol (2-butanol): It has a branched structure, with the hydroxyl group attached to the second carbon atom. It's used as a solvent and in the manufacture of perfumes and pharmaceuticals.
- Tert-butanol (2-methyl-2-propanol): This isomer is highly branched, with the hydroxyl group attached to a carbon atom that is itself attached to three other carbon atoms. Tert-butanol is used primarily as a solvent and as a chemical intermediate.

Calcium nitrate (Ca(NO₃)₂) is a chemical compound made up of calcium and nitrate ions. It typically appears as a white, crystalline solid that is highly soluble in water.
Uses of Calcium Nitrate:
-
Fertilizer: It’s widely used in agriculture as a high-nitrogen fertilizer, providing plants with essential nutrients like nitrogen and calcium for healthy growth, especially in conditions where soil quality is poor.
-
Concrete and Construction: Calcium nitrate is used as an admixture in concrete to control the setting time, especially in cold weather conditions. It helps prevent the formation of harmful compounds in concrete, like calcium sulfoaluminate.
-
Water Treatment: It can be used in water treatment processes to help control algae growth by reducing phosphorus levels in water bodies.
-
Explosives: It’s also used in the production of explosives, where it serves as an oxidizing agent.

Double Gas Mask
- Dual Cartridges: The mask has two cartridges, one on each side of the mask, which contain filters to purify the air. These cartridges are usually filled with activated charcoal or other filtering materials designed to absorb or neutralize specific chemicals or particulates.
- Seal: A proper seal between the mask and the wearer's face is crucial to ensure that no contaminated air can leak in. This seal is typically achieved through adjustable straps that secure the mask snugly against the face.
- Exhalation Valve: Most masks have an exhalation valve to allow the wearer to exhale easily without causing a buildup of moisture or CO2 inside the mask.
- Visibility: The mask is designed to provide adequate visibility while still offering protection. Some models have anti-fog features to prevent the visor from fogging up during use.
- Compatibility: Depending on the specific hazards in the environment, different types of cartridges can be used with the mask. These cartridges are often color-coded for easy identification.
- Fit Testing: It's essential for users to undergo fit testing to ensure that the mask provides an effective seal. Fit testing involves performing various exercises to check for any leaks around the mask's edges.

Field Stain A and B 25gm
Field Stain A
- Composition: Field Stain A is typically an aqueous solution of methylene blue, which stains the nuclei of cells blue.
- Function: It primarily stains the acidic components of the cell, including DNA and RNA. This makes the nuclei and certain cytoplasmic components appear blue.
Field Stain B
- Composition: Field Stain B is usually an aqueous solution of eosin, which stains the basic components of the cell pink.
- Function: It stains the cytoplasm and extracellular components pink to red. Eosinophilic structures, such as red blood cells and certain granules, are highlighted by this stain.
Usage
- Procedure:
- Prepare the blood smear: A drop of blood is spread thinly on a glass slide and allowed to air dry.
- Apply Field Stain A: The dried smear is immersed in Field Stain A for a short duration, typically around 5-10 seconds.
- Rinse: The slide is briefly rinsed in water to remove excess stain.
- Apply Field Stain B: The smear is then immersed in Field Stain B for another short duration, around 5-10 seconds.
- Rinse and dry: The slide is rinsed again in water and allowed to air dry.
- Outcome: The resulting stained smear allows for the differentiation of various cell components, making it easier to identify and analyze blood cells and any parasitic infections like malaria.
