Buffers and Reagents

Biochrom Amino Acid Analysis reagents and buffers are manufactured from high quality chemicals and materials and subjected to rigorous control procedures, under the ISO 13485 Quality System. Our buffers are guaranteed to give accurate and reproducible results for up to 3 years from manufacture, provided the storage conditions are adhered to.

All reagents have stable chemistry and have been formulated to be stored at ambient temperature so, conveniently, do not need refrigeration.

Biochrom instruments are supplied with the appropriate chemical kit for the system ordered. These kits contain the chemicals and consumables needed for most routine analyses. Buffer kits or individual buffers and consumables may be purchased to enable continuity of analysis. On the instrument, buffers and detection reagent are stored under an inert atmosphere to ensure stability.

Biochrom buffers and reagents can be purchased as kits or as individual reagents.

EZ Nin: Ready to use ninhydrin formulation for ion exchange chromatography systems

EZ Nin is ready to use- no preparation is required for consistently excellent measurement of amino acids using ion exchange chromatography. The patented formulation combines ease of use with unprecedented chemical stability, providing you with the confidence you require when evaluating concentrations of amino acids for diagnosis and monitoring of in born errors of metabolism (IEMs). EZ Nin is also unaffected by complex sample matrices allowing for excellent amino acid analysis of protein hydrolysates.

Key features and benefits include:

Ready to use: No preparation is required: no mixing, no nitrogen, no waiting.

Long-lasting: The patented formula guarantees no degradation with time or with exposure to oxygen.

Less waste: Simply top up your instrument with EZ Nin for non-stop analysis.

*ISO 13485 certified. This is an internationally recognized standard based on the ISO 9001:2000 and designed to provide suppliers of analytical and medical instrumentation with a common approach to applying a Quality Management System.

Certification to ISO 13485 satisfies a significant portion of the EU Directive requirements for marketing medical devices in Europe and the US FDA Quality System Regulations (21 CFR 820). It includes criteria such as risk assessment relating to possible manufacturing and supply chain defects, and a requirement to promote regulatory awareness throughout the company.
