We are manufacturing best Quality calcite powder and various quality raw minerals in Calcite is very useful minerals and we provide best calcite minerals. Carbonate of Calcium known as Chalk Powder and Limestone Powder widely used mineral. Calcite powder in wide range with best rates. Various Striking Features: High dispensability, higher impact strength, Low oil absorption, Easy processing, Smooth surface finish and excellent dimensional stability. We offer highly pure and stable range of Calcite Powder that is composed of natural calcium carbonate. Calcite Powder is a natural form of Calcium Carbonate, purity and free flowing in nature. Various range in available calcite powder in India and we offer White Calcite Powder is used in plastics as filler, due to its high dispensability, easy processing, high impact resistance, low oil absorption smooth surface finish, compatibility with polymers, organic additives and magnificent dimensional solidity. We are one of the prominent Calcite Powder . Calcite displays an unusual predictable called retrograde solubility. We are reputed one of the important organization which is Natural Calcite Exporters in . The Calcite Mineral is naturally mined in the form of lumps. Calcite crush formed is using in filler in rubber and textile goods, used in the ceramics industry, preparation of glazes, manufacture of paint and distemper, manufacture of cement, metal polish, calcium carbide, transparent clear crystals used in the optical industry, use in optical instruments. The transfer of calcite can dramatically increase the porosity and permeable of the rock. In mining process the calcite is sorted out into various kinds of color grades. Calcite forms mineral coatings that cement existence rock grains together. Applications : Oil Exploration / Oil Drilling industry Plastics Rigid PVC Pipes LDPE Master Batches Paints, Inks, Powder Coating and Ceramic Welding Rods Automotive and Furniture Compounds. Rubber Industry Leather Cloth Industry As a flux in Glass Industry and in sizing of Textile Goods Coated Calcite Powder : We provide coating of Steric Acid on Calcite Powder. The Coated Calcium Carbonate powder is used in plastic compounds manufacturing to avoid moisture contains. Grades : Calcite powder is available from 100 Mesh to 700 Mesh. Calcium Carbonate is also available in granules size. Packing : Available in 25Kg, 50 Kg. 1000 kg, 1250 Kg & 1400Kg
Something about acridinium ester (NSP-SA-NHS) Acridine esters (NSP-SA-NHS) CAS: 199293-83-9 and related compounds have been proven to be very advantageous chemiluminescent labels, with stability, activity and sensitivity exceeding those of radioactive isotopes. Under alkaline conditions, the NHS will leave and the acridine ester will bind to the protein with a stable amide bond to form an acridine compound. After the reaction is completed, the excess acridine salt is removed through a desalting column. In the presence of alkaline hydrogen peroxide, acridine-labeled protein does not require enzymatic catalysis to emit light on its own. After adding the excitation reagent, the system immediately releases photons, which can be detected with a 430nm standard photometer. This light-emitting process is very short (the entire process occurs in less than 2 seconds), and the trigger scheme must add an internal photometer and photon detector. Proteins, peptides, antibodies, and nucleic acids can all be labeled with acridine. The labeled compound emits light rapidly under the excitation of basic hydrogen peroxide, and the labeled compound can be detected by collecting photons. Product stability: 1. It is stable in acidic solution (pH4.8, especially in alkaline solution, the acridine compound is partially hydrolyzed to reduce its stability, and the hydrolysis process is a dark reaction process that does not emit light; the degree of hydrolysis increases with the increase of pH, and the degree of hydrolysis increases with the increase of temperature. Increase and increase. 3. The stability of acridine amide is higher than that of acridine ester structure, and the ability to resist hydrolysis is stronger. 4. Acridine ring or phenol ring or benzene sulfonyl ring is connected with a methyl group and other electricity-donating groups. Due to the large steric hindrance, the thermal stability is increased; the electron withdrawing group is attached, which is beneficial to the nucleophilic substitution reaction Its stability decreases. 5. Suggestion: Use a weakly acidic buffer as much as possible for the storage buffer after coupling, and bubbling nitrogen to remove oxygen. Store at low temperature, sealed and protected from light. Conditions can be made into freeze-dried samples and then stored. Precautions: 5. The acridinium ester luminescence process is very short (the whole process takes less than 2 seconds), and the trigger scheme must add an internal photometer and photon detector; in addition, this product can also use a multifunctional microplate reader equipped with an autosampler Perform luminescence data collection to minimize the influence of sample addition time on the collected signal.
