Perspex rod
A Perspex rod is a solid cylindrical rod made from a transparent thermoplastic called polymethyl methacrylate (PMMA), which is commonly known as acrylic. Perspex is actually a brand name for acrylic sheets and rods. These rods are known for their optical clarity, lightweight nature, and durability, making them useful in various applications such as in optics, lighting, crafts, and even in scientific experiments like demonstrating principles of optics in classrooms.
Petri Dish (glass)
A Petri dish is a shallow, flat, cylindrical, lidded container typically made of glass or clear plastic. It is used in laboratory settings for the cultivation and observation of microorganisms, cells, or small organisms under controlled conditions. The dish provides a sterile environment that allows scientists and researchers to study the growth, behavior, and interactions of these biological entities, making it a fundamental tool in microbiology, cell biology, and other related fields.
Petri dish (plastic)
A Petri dish is a shallow, flat, cylindrical glass or plastic dish with a loose-fitting cover used in laboratories for the cultivation of microorganisms or small plants. It provides a controlled environment for the growth of cultures by providing a nutrient medium on which the organisms can feed and grow. Petri dishes are commonly used in microbiology, molecular biology, and other biological research fields for tasks such as bacterial culture, yeast culture, and tissue culture. They're indispensable tools in scientific research for studying the growth, morphology, and behavior of various organisms under controlled conditions.
Petroleum jelly 175kg
Petroleum jelly is a semi-solid mixture of hydrocarbons, usually derived from petroleum, that has a smooth and greasy texture. It is also known as petrolatum or Vaseline, which is a trademarked brand name. Petroleum jelly is commonly used as a moisturizer to soothe and protect dry, cracked, or irritated skin. It is also used in a variety of other applications, such as lubrication, waterproofing, and as a base for some cosmetics and pharmaceuticals.
Petroleum Resin C9 Hydrocarbon 25 kg Bag
Petroleum resin C9 hydrocarbon, also known as C9 hydrocarbon resin or simply C9 resin, is a type of thermoplastic resin that is derived from the distillation of petroleum products. It is composed primarily of aliphatic and aromatic hydrocarbons, and is typically produced by the polymerization of C9 fraction of petroleum, which is obtained by the distillation of crude oil.
C9 hydrocarbon resin is a highly versatile material that finds use in a wide range of industrial applications, including adhesives, coatings, printing inks, rubber compounding, and more. It is valued for its excellent solubility, compatibility with other resins, and ability to enhance the properties of other materials, such as adhesion, tack, and flexibility.
In summary, petroleum resin C9 hydrocarbon is a type of polymer derived from petroleum that is widely used in various industries for its unique properties and compatibility with other materials
Ph meter strips
pH meter strips, also known as pH test strips or pH paper, are simple, convenient tools used to measure the acidity or alkalinity of a solution. Typically composed of a strip of absorbent paper impregnated with pH-sensitive dyes, they change color based on the pH level of the solution they come into contact with.
Phenol Detached Crystals 500gm
Phenol Detached Crystals" seems to be a specific phrase related to the physical state or appearance of phenol. Phenol, also known as carbolic acid, is an aromatic organic compound with the molecular formula C6H5OHC_6H_5OHC6H5OH. It is a white crystalline solid at room temperature and can be used in the production of plastics, pharmaceuticals, and other chemicals.
If you are referring to "detached crystals," this likely describes a situation where phenol has crystallized out of a solution and the crystals are not adhering to each other or to the container, appearing as separate entities. This can happen under certain conditions, such as when a phenol solution cools down or evaporates, leading to the formation of individual phenol crystals.
Phenol Red 500grams
Phenol Red is a chemical compound with the molecular formula C₁₆H₁₃O₆S. It is a pH indicator dye that changes color in response to pH levels. In acidic conditions (pH below 6.8), it appears yellow, and in alkaline conditions (pH above 8.2), it turns red. This makes it useful in various applications, including biological and environmental sciences, where monitoring pH changes is crucial. Phenol Red is also utilized in medical diagnostics and in the preparation of culture media for microbiology.
Phenolphthalein Solution 500ml
Phenolphthalein is a chemical compound commonly used as a pH indicator in titrations and other analytical chemistry applications. It is a colorless crystalline solid that is often dissolved in alcohol to create a phenolphthalein solution.
Properties of Phenolphthalein Solution
- pH Indicator:
- Acidic Solutions (pH < 8.2): Colorless
- Slightly Basic Solutions (pH 8.2 - 10.0): Pink to fuchsia
- Strongly Basic Solutions (pH > 10.0): Colorless
- Solubility: Phenolphthalein is soluble in alcohol and slightly soluble in water.
Preparation of Phenolphthalein Solution
- Ingredients:
- Phenolphthalein powder
- Ethanol (or another suitable alcohol)
- Distilled water
- Procedure:
- Dissolve 1 gram of phenolphthalein powder in 100 mL of ethanol.
- Dilute the solution with distilled water to make a 1% phenolphthalein solution (typically 100 mL of the ethanol solution to 900 mL of water).
