Chemical Oxygen Demand (COD) is defined as the amount of a specific oxidant that reacts with the sample under controlled conditions. The quantities of oxidant consumed is expressed in terms of its oxygen equivalence. Because of Dichromate ions specific oxidant properties (CrO72-) unique chemical properties it gets reduced to the chromic ion (Cr3+) in COD test. COD is a defined test the extent of sample oxidation can be affected by digestion time reagent strength and sample COD concentration. COD is often used on a measurement of pollutants in waste water and natural water. To determine COD two methods are useful the open reflux method is suitable for a wide range of waste water and large sample size is preferred. Another is the closed reflux method is suitable for smaller quantities. It requires homogenisation of sample. Accurate measurement of sample values as well as reagent volumes and concentration are critical. Principle Most type of organic matter are oxidised by a boiling mixture of Chromic and Sulphuric acid. A sample is heated in strongly acid solution with known excess of potassium dichromate. After digestion the remaining unreduced dichromate is titrated with Ferrous Ammonium Sulphate to determine the amount of dichromate consumed and the oxidized matter is calculated in terms of oxygen equivalent. Closed result method is used for AQUASOL AE407 COD test kit. This kit is applicable to COD values between 40 to 400 mg/l. Obtained high values by dilution.

This test is used to determine the RF Antibody in the blood . Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Principle: The RF-Latex is a slide agglutination test for the qualitative and semi-quantitative detection of RF in human serum. Latex particles coated with human gamma globulin are agglutinated when mixed with samples containing RF.

The polymerase chain reaction (PCR) has become a fundamental tool in molecular research and clinical testing.the most significant advance is real-time PCR, combining both amplification and detection into one instrument as a superior solution for nucleic acid quantification. Real-time PCR is enabled by monitoring the reaction with double stranded DNA dyes or specific probes, including hydrolysis, hybridization, and conformation-sensitive probes. PCR product and probe melting analysis continues to improve in resolution, allowing greater sequence detail for genotyping and variant scanning. Microfluidic platforms and digital PCR are destined to find more applications in the future.

The HI3814 is a chemical test kit that determines that uses titration and direct measurement to measure six parameters common in environmental testing: acidity, alkalinity, carbon dioxide, hardness, dissolved oxygen, and pH. The HI3814 is supplied with all of the necessary reagents and equipment to perform each analysis, and all reagents are individually available as they run out. Features at-a-glance Complete setup All required materials are included with the test kit, such as the pH tester, sample beaker, indicator and reagent bottles and packets, and glass bottle for dissolved oxygen. High resolution All tests provide a high resolution based on the expected range of measurement. Replacement reagents available There is no need to buy a new kit when reagents are exhausted. The reagents for each parameter can be ordered individually. Significance of Use The six most important parameters in environmental applications can be monitored with this combination chemical test kit. They include: acidity, alkalinity, carbon dioxide, dissolved oxygen, hardness, and pH. This kit is ideal not only for professionals, but also for students studying environmental science, as it offers great performance and ease of use. HI3814 is equipped with all the accessories and reagents to perform over 100 tests for each parameter. The pHep®, our popular pH electronic tester, is included for your convenience. This small and easy to use pH meter will provide more accurate and reliable pH readings than conventional litmus paper. The pHep® also has the added benefit of introducing students to the use of a pH meter.
