  • Consist of a 100 ml. conical borosilicate flask. A brass rod passes through a cork which seals the mouth of flask, upper end of which is in the form of a disc and at lower end gold leaf is attached MS-423 PVG GOLD LEAF ELECTROSCOPE FLASK TYPE
  • GOLD LEAF ELECTROSCOPE A scientific instrument used to assess the presence of electrical charges on a body is known as an Electroscope. A gold-leaf electroscope is electroscope that consists of gold leaves and is used for detecting the electrical charge of the body. Strongly constructed ,powder coated, sheet metal walls of the electroscope and  are mounted on a plastic base. Front glass window slides up to allow insertion of ionizing material in chamber. Transparent scale is attached inside chamber to measure the deflection of the gold leaf. When a charged object touches the electroscope's brass disc, the electric charge gets transferred to the gold leaves through the rod. This results in the gold leaves moving away from each other as like charges repel each other. The movement of the leaves shows the presence of charges in a body. The gold leaves return to their normal position after some time. This happens because they lose their charge after a while. This process is called electrical discharge. The charges in the gold leaves would also be discharged when someone touches the brass rod with empty hands. In that case, the charges are transported to the earth through the human body.

NSG- 9 SALT BRIDGE WITH SINTERED DISC A salt bridge is a device used in an electrochemical cell for connecting its oxidation and reduction half cells wherein a weak electrolyte is used. In other words, a salt bridge is a junction that connects the anodic and cathodic compartments in a cell or electrolytic solution. Glass tube salt bridges commonly consist of U-shaped  tubes filled with a relatively inert electrolyte. A salt bridge is an important part of an electrochemical cell. A salt bridge is a glass tube  that connects the two sides of a an electrochemical cell and provides electrolytes needed to neutralize the solutions in both sides of the cell. Purpose of Salt Bridge The function of a salt bridge in electrochemical cell is to keep electrical neutrality in the solutions by providing an electrical contact between both sides of the galvanic cell without any mixing of the solutions. Without a salt bridge, negative charge will collect into just one side of the electrochemical cell and the other side will be positively charged as ions are created and become part of each sides solution. If both sides of the cell become polarized in charge then the electrical current will not be produced. The purpose of salt bridge is to continue the reaction that produces the electrical current, without it charge would polarize and electrical current would cease. Essentially the purpose of a salt bridge would be maintain neutrality of charge between the two sides of an electrochemical cell so that electric current can continue to be produced. Construction : Apparatus consist of Inverted Glass U tube,With over all  height 100 mm ends closed with Sintered Disc . Width 80 mm.Diameter of arms.13 mm Material : Chemical resistant clear Borosilicate 3.3 glass and Sintered Disc

SALT BRIDGE WITH SINTERD DISC

NSG 11 MEMBRANE FILTER HOLDER WITH STANDARD JOINT FITTING A Membrane Filter Holder Assembly is a laboratory apparatus used for the filtration of liquids or gases. It consists of a filter holder and support for a membrane filter, which is placed between the two. The filter holder is typically made of metal and holds the filter in place during filtration. The membrane filter is usually made of a thin, porous material that acts as a barrier to trap particles or contaminants in the liquid or gas being filtered. The holder assembly provides a secure and leak-proof environment for the filtration process and makes it easy to replace the filter after use. Membrane filter holder assemblies are commonly used in water treatment, air quality control, microbiology, and other scientific and industrial applications where precise filtration of liquids or gases is required. PVG’s Membrane Filter Holder with Standard Joint Fitting is a crucial laboratory equipment for the precise filtration of liquids and gases. This useful and reliable assembly consists of a filter holder that securely supports a membrane filter, ensuring effective separation of contaminants. Constructed from durable materials, it is perfect for a range of applications in microbiology, water treatment, pharmaceuticals, and more. Specifications: Membrane Filter Diameter: 47 mm Funnel Cup Volume: 300 mL Clamp Material: Anodized aluminum clamp for corrosion resistance Filtration Flask: Made from heavy-duty borosilicate glass 3.3, designed to withstand high vacuum conditions during filtration. Packaging: In Bubble sheet or Die-cut foam packaging ensures safe delivery and handling of glassware. PVG’s Glassware is printed with chemical-resistant White Enamel colors for life long usage. Standard Joint Fittings Standard joint fittings are used to connect the membrane filter to other components in a filtration system. These fittings are designed to provide leak-proof connections and are often made of materials compatible with the fluids being filtered (like glass, plastic, or stainless steel). Applications: Water Purification: Removing contaminants from drinking water. Pharmaceuticals: Sterile filtration of solutions and drugs. Food and Beverage: Clarifying juices and beverages, or sterilizing products. Considerations: Material Compatibility: Ensure the filter and fittings are compatible with the substances being filtered. Pore Size: Choose an appropriate pore size G1,G2,G3 or G4 based on the desired filtration level. Temperature and Pressure Ratings: Ensure the filter can withstand the operational conditions. Final Conclusion: PVG’s Membrane Filter Holder with all Standard Joint Fitting is used for efficient and reliable filteration, making it an essential component in any Research laboratory filtration setup.
