Cotton twine is known for its softness, pliability, and ability to hold knots securely, making it useful in a wide range of tasks where a reliable and biodegradable cord is needed.
Cresol Red Indicator 25gm
Cresol Red is a pH indicator dye commonly used in titrations and other laboratory experiments to determine the pH of a solution. It changes color based on the acidity or basicity of the solution it is in. Here are its key characteristics:
- Chemical Structure: Cresol Red is a sulfonephthalein dye with the molecular formula C21H18O5S.
- Color Change: It transitions from yellow in acidic solutions (pH < 1.8) to red in neutral solutions (pH around 7.0), and then to purple in basic solutions (pH > 8.8).
Crystal Violet 1% alcohol solution 25gm
Crystal Violet, also known as gentian violet, is a synthetic dye with antibacterial and antifungal properties. It's commonly used in microbiology as a staining agent to visualize bacteria and other microorganisms under the microscope.
A 1% alcohol solution of Crystal Violet would mean that 1 gram of Crystal Violet dye is dissolved in 100 milliliters of alcohol. This solution is typically used in Gram staining, a differential staining technique used to classify bacteria into two groups: Gram-positive and Gram-negative.
In Gram staining, Crystal Violet is the primary stain that imparts a purple color to both Gram-positive and Gram-negative bacteria. The alcohol serves as a solvent and fixative, helping the dye penetrate the bacterial cell wall and retain its color during the staining process.
Cupric Carbonate 500gm
Cupric carbonate, also known as copper(II) carbonate, is a chemical compound with the formula CuCO3. It exists in nature as several different minerals, including malachite and azurite, which are valued for their vibrant green and blue colors, respectively. Cupric carbonate can also be synthesized in the laboratory.
In its natural form, cupric carbonate is often used as a pigment in paints and dyes due to its striking color. It has also been used historically as a source of copper in various applications, including as a fungicide in agriculture.
Cupric carbonate is insoluble in water, but it can react with acids to form soluble copper salts. Additionally, it can decompose upon heating to release carbon dioxide and form copper(II) oxide.
It's important to handle cupric carbonate with care, as copper compounds can be toxic if ingested or inhaled in large quantities.
Cupric Chloride 250gm
Cupric chloride, also known as copper(II) chloride, is a chemical compound with the formula CuClā. It appears as a yellowish-brown powder in its anhydrous form and turns into a blue-green crystalline solid when hydrated. This compound is highly soluble in water, forming a blue solution.
Properties:
- Chemical Formula: CuClā
- Molecular Weight: 134.45 g/mol
- Appearance: Yellowish-brown powder (anhydrous), blue-green crystals (hydrated)
- Solubility: Highly soluble in water and ethanol
Cupric Oxide 100gm
Cupric oxide, also known as copper(II) oxide, is a black solid with the chemical formula CuO. It is a significant compound of copper and has various applications in different fields. Here are some key points about cupric oxide:
Properties:
- Chemical Formula: CuO
- Appearance: Black or dark brown powder.
- Molecular Weight: 79.545 g/mol
- Melting Point: 1,326 Ā°C (2,419 Ā°F)
- Density: 6.315 g/cmĀ³
- Solubility: Insoluble in water but soluble in acids.
Production:
Cupric oxide can be produced by several methods, including:- Thermal Decomposition: Heating copper(II) nitrate, copper(II) carbonate, or copper(II) hydroxide in the absence of oxygen.
- Direct Oxidation: Heating metallic copper in the presence of oxygen.
Cupric Sulphate Anhydrous
Cupric sulfate anhydrous refers to the form of copper(II) sulfate that does not contain water molecules in its crystal structure. It is used similarly to the hydrated form (cupric sulfate pentahydrate) in laboratory settings, often in analytical chemistry and as a source of copper ions in various reactions and processes.
Deionized water 20 litres
Deionized water, also known as demineralized water, is water that has had its mineral ions (such as sodium, calcium, iron, and copper) and dissolved solids removed through a process called ion exchange.
Distilled water, on the other hand, is water that has been purified by boiling it into steam and then condensing the steam back into water. This process removes impurities such as minerals, bacteria, and other contaminants.
Both deionized and distilled water are highly purified forms of water, but the processes used to purify them are different. Deionized water is typically used in laboratory settings or in industrial processes, while distilled water is commonly used in medical applications, humidifiers, and in some consumer products
Dextrose Monohydrate glucose 500gm
Dextrose monohydrate is a simple sugar derived from corn starch and commonly used as a food additive or sweetener. It is a white, crystalline powder that consists of glucose molecules with one molecule of water attached. Dextrose monohydrate is chemically identical to glucose and is often referred to as a glucose monohydrate.
In the food industry, dextrose monohydrate is valued for its sweet taste, high solubility, and ability to enhance flavors. It is frequently used in the production of confectionery, baked goods, beverages, and dairy products. Dextrose monohydrate is also utilized in pharmaceutical formulations, particularly as a source of energy for intravenous solutions or in oral rehydration products.
Diastase Enzyme Powder 100gm
Diastase enzyme powder, also known simply as diastase, is an enzyme primarily derived from malted barley. It functions as an alpha-amylase enzyme, which means it catalyzes the hydrolysis of starch into simpler sugars such as maltose and glucose. This enzymatic action is particularly valuable in brewing and baking industries, where diastase aids in the conversion of starches into fermentable sugars during the mashing process in brewing or dough fermentation in baking. In summary, diastase enzyme powder plays a crucial role in breaking down starches into sugars, thereby facilitating fermentation and enhancing the flavor and texture of various food products
