Saudi Arabia cod reagent vials for water analysis

iTRAQ ® Reagents are an isobaric, peptide-tagging technology that enable you to label all primary amines, regardless of peptide class. Because important information, such as post-translational modifications (PTMs), is retained, this tagging system allows you to extract more detailed information from your samples.

COD. The EasyPREP COD-200 is an automated chemical oxygen demand (COD) analyzer. Features include automated digestion, sample time tracking, mixing, analysis (built-in spectrophotometer), data transposition and storage.

17/6/2011 · The Vialtweeter from Hielscher is designed to apply the technology of sonication to vials such as autosampler vials, storage vials and reagent vials without the need to open the cap or any water bath. Sonication is an effective method for the mixing, homogenising, emulsifying, dispersing, disintegration and degassing of liquids by means of

Chemical oxygen demand, also known as COD, indirectly measures the organic matter in water samples. COD is regularly performed in wastewater as it is a quicker and more convenient test to perform than biological oxygen demand (BOD). Careful monitoring of COD, and then following up with BOD tests can allow for proactive corrections to the

It is ideal for water samples, large volume parenterals and water rinse from medical devices. The PYROGENT TM –5000 Kinetic Turbidimetric Assay is measured at the 340 nm wavelength and has a sensitivity range from 0.01 to 100.0 EU/ml. PYROGENT TM -5000 Bulk Kinetic Turbidimetric LAL Assay N588 is made to order and requires a lead time.

COD-free vials do not contain mercury, which makes them more susceptible to chloride interferences, but greatly reduce the safety and environmental risks of handling mercury. As a result, these reagents are ideal for routine analysis where no or very low chloride concentrations are expected.
