Whetstone bridge with pencil jockey
A Wheatstone bridge is a circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit. The classic Wheatstone bridge consists of four resistors forming a loop with a voltage source applied across one pair of diagonally opposite corners and a galvanometer connected across the other pair. When the bridge is balanced, the galvanometer indicates zero current flow, indicating that the ratio of the two resistor values on one side of the bridge equals the ratio on the other side.
A "pencil jockey" is a colloquial term for a technician or engineer who manually adjusts the resistors in the Wheatstone bridge circuit to achieve balance. The term "pencil" refers to the fine adjustments often made using a pencil or other tool to precisely dial in the resistance values.
In a laboratory setting, the Wheatstone bridge with a pencil jockey would be used to measure unknown resistances with high precision. The technician would adjust the resistors until the galvanometer reads zero, indicating a balanced bridge, at which point the ratio of the known resistors to the unknown resistor can be used to calculate its value. This setup allows for accurate measurement of resistances in various experimental setups, calibration procedures, or quality control processes.
White oil 162kg
White oil is a highly refined, colorless, odorless, and tasteless mineral oil that is commonly used in a variety of industrial, cosmetic, and pharmaceutical applications. It is produced by refining crude oil to remove impurities, resulting in a pure and stable oil that is chemically inert and non-toxic. White oil is typically characterized by its high purity, low viscosity, and low volatility, which makes it an ideal choice for applications where cleanliness, stability, and safety are important. Some common uses of white oil include as a lubricant, a carrier oil for fragrances and flavors, a plasticizer in the manufacturing of plastics, and as an ingredient in personal care products such as lotions and creams.
Wool Bonnet (12 pcs)
A wool bonnet is a circular pad made from wool fibers, often used with a polishing machine to apply or remove wax, polish, or other automotive detailing products on a vehicle's surface.
The wool bonnet's construction involves dense layers of wool fibers tightly stitched or woven together, providing a plush yet durable surface for polishing tasks. The natural properties of wool, including its softness and ability to hold polishing compounds, make it an ideal material for achieving a smooth and glossy finish on metals, wood, plastics, and other materials.
When attached to a polisher or buffer, the wool bonnet spins or rotates at high speeds, allowing the abrasive particles within polishing compounds to effectively smooth out imperfections, scratches, and blemishes on the surface being worked on. The gentle yet thorough polishing action of the wool bonnet helps to restore shine and luster to surfaces, leaving behind a professional-grade finish.
Wool Bonnet String Type (12 pcs)
A wool bonnet string type is a polishing or buffing tool used in automotive detailing or metalworking. It is a circular pad made from wool fibers attached to a backing plate, which is then mounted on a rotary or orbital polishing machine. The wool bonnet is designed to be used with polishing compounds to remove imperfections, oxidation, or scratches from surfaces such as automotive paint, metal, or wood.
The wool bonnet's soft and natural fibers provide a gentle yet effective way to achieve a smooth and polished finish without causing damage to the material being worked on. It is commonly employed in tasks like polishing car paint, metal surfaces, or wooden furniture to enhance their appearance and restore their original luster.
Xantham Gum 25kg
Xanthan gum is a polysaccharide, or a type of carbohydrate, that is commonly used as a thickening and stabilizing agent in food and industrial products. It is produced through a fermentation process by the bacterium Xanthomonas campestris, and has a unique ability to thicken liquids even at low concentrations, making it a popular ingredient in many food products such as sauces, dressings, and baked goods. Xanthan gum is also used in a variety of industrial applications, including in the production of cosmetics, pharmaceuticals, and oil drilling fluids. It is considered safe for consumption by most regulatory agencies around the world, and is often used as a substitute for other thickeners, such as cornstarch or gelatin.
Xylene 180 Kg Drum
Xylene refers to a group of three isomeric aromatic hydrocarbon compounds: ortho-xylene, meta-xylene, and para-xylene. It is a colorless, flammable liquid with a sweet odor. Xylene is primarily used as a solvent in various industrial processes, including the production of paints, coatings, adhesives, and rubber. It can also be found in small amounts in gasoline and other petroleum products.
