This product is manufactured by a reputable SKC company from the United States and its design is designed to easily collect and transport different samples of gases. SKC Tedlar Bag is specifically suitable for sampling natural and composite gases such as carbon monoxide, carbon dioxide, methane and hex floweride sulfur.\r\nThis bag enables gases to empty gas using a special design propylene outlet valve. Tedlar Bag is available in volumes of 1, 3, 5, 10 liters and is suitable for various biogenic gases and pollutants in the environment.\r\nUsing these bags helps professionals who work to measure air pollution and dangerous gases to collect detailed samples for further analysis.\r\nIt should be noted that these bags are also suitable for collecting chlorine solvent samples and hydrocarbons.\r\nThere are a few important points in using the Tedlar Bag: Never fill in more than two -thirds of the bag, keep the bags away from direct sunlight and make sure the tag is accurately placed on them. \r\nAlso, avoid contaminating the samples and have a similar sample as a backup.\r\nFor more information on the gas sampling bag and existing prices, please contact the Volume Equipment Experts.

What is zinc acetate?\r\nZinc acetate is a type of salt with the formula Zn(CH3CO2)2, which usually exists as Zn(CH3CO2)2 · 2H2O dihydrate. Both the hydrated and anhydrous forms are colorless solids and are produced through the reaction between zinc oxide and acetic acid.\r\nConsidering that zinc is an essential element for the growth and development of the human body, zinc acetate can be used as a food supplement to treat zinc deficiency. It plays an important role in the synthesis of cholesterol, protein and fat.\r\n\r\nZinc acetate is a component of some medicines, for example, lozenges for the treatment of colds. Zinc acetate can also be used as a dietary supplement. As a daily oral supplement, it is used to inhibit the absorption of copper in the body as part of the treatment of Wilson's disease. Zinc acetate is also sold as an astringent in the form of an ointment, topical lotion, or combined with antibiotics such as erythromycin for the topical treatment of acne. It is usually sold as a topical anti-itch ointment.\r\n\r\nZinc acetate is also used as a catalyst for the industrial production of vinyl acetate from acetylene. \r\n\r\nIn the industry, it has various uses, including preserving wood, making other zinc salts as well as ethylene acetate, using it as a dye and analytical reagent.

What is lead acetate?\r\nLead(II) acetate, also known as lead acetate, lead diacetate, plumbus acetate, sugar of lead, sugar of lead, salt of Saturn, or Goulard's powder, is a white crystalline chemical compound with a slightly sweet taste. Its chemical formula is usually expressed as Pb(CH 3 COO) 2 or Pb (OAc) 2, where Ac represents the acetyl group. Like many other lead compounds, it is toxic.\r\n\r\nLead acetate is soluble in water and glycerin. With water, it forms the trihydrate, Pb(OAc)2·3H2O, which is a colorless or white floral monoclinic crystalline substance.\r\nIt is used as a reagent for making other lead compounds and as a stabilizer for some paints. In low concentrations, it is the main active ingredient in progressive types of hair color. Lead(II) acetate is also used as a drying agent in textile printing and dyeing and as a drying agent in paints and varnishes. Historically, it was used as a sweetener and preservative in foods and for cosmetics.

What is manganese acetate?\r\nManganese acetate (II) chemical compounds with the formula Mn(CH3CO2)2 · (H2O)n where n=0,2,4. Manganese acetate exists as a white or pale pink crystalline solid.\r\nManganese acetate can be prepared by reacting manganese (II) oxide (MnO) or manganese (II) carbonate (MnCO3) with acetic acid (CH3COOH). It can also be obtained by reacting manganese (II) chloride (MnCl2) with sodium acetate (CH3COONa).\r\n\r\nApplications of manganese acetate\r\nCatalyst: Manganese acetate is usually used as a catalyst in various chemical reactions. It can promote oxidation, esterification and other organic transformations. It is especially effective in oxidation reactions using peroxides or oxygen as oxidizing agents.\r\n\r\nDyeing and pigment: Manganese acetate is used in the production of dyes and pigments. This substance is used as a precursor or intermediate in the synthesis of manganese-based dyes, which can produce various shades of pink, red, or brown.\r\n\r\nAnimal feed supplement: Manganese is an essential micronutrient for animals, including livestock and poultry. Manganese acetate is used as a dietary supplement in animal feed formulations to ensure adequate levels of manganese for proper growth, bone development and metabolism.\r\n\r\nLaboratory reagent: Manganese acetate acts as a reagent in analytical and research chemistry laboratories. It can be used to detect or determine other substances such as organic compounds or metal ions.\r\n\r\nPolymerization: Manganese acetate has been used in the polymerization of various organic compounds. It can act as a catalyst or co-catalyst in certain polymerization reactions, including the synthesis of polyesters or other polymeric materials.\r\n\r\nIt is important to use manganese acetate with caution, as it can be harmful if swallowed, inhaled, or in contact with the skin or eyes. Proper safety precautions and procedures should be followed when working with this compound.
