Life Science Products
Basic Information

Quality is our highest priority – for reliable analyses and reproducible results
It is hard to imagine carrying out analyses in the life sciences field these days without using high-quality disposables. For almost 25 years, BRAND has offered high-performance plastic products for various applications.

We start by asking users around the world for input on product details, and then select raw materials and design injection-molding tools to ensure the highest product performance. Finally, the entire manufacturing process is strictly controlled, with quality assurance testing in accredited internal and external laboratories.

Internal quality controls and independent laboratory tests

All products are subjected to a number of optical and functional tests before they are tested for molecular-biological contaminants. For example, PCR products are tested for evaporation losses and PCR plates are subjected to stringent vacuum tests to ensure that the systems satisfy your highest expectations.
After the disposable items have successfully completed this internal process, the products are examined by an independent accredited laboratory. Sensitive detection methods are used to ensure that the products, depending on the intended use, contain no DNA, DNase, RNase, endotoxins or ATP.

Starting materials

Sensitive applications, such as enzyme tests, PCR or DNA purification, require plastic disposable products of the highest quality. The proper selection of raw materials is a significant step in the manufacture of high-quality products. Over many years, polypropylene and polystyrene have earned their place as preferred materials for life science consumables. These materials often come into direct contact with expensive reagents and valuable samples. For manufacturing pipette tips, BRAND uses specially selected PP types, free from the additives di-(2-hydroxyethyl) methyldodecylammonium (DiHEMDA) and 9-octadecenamide (oleamide).

Both of these additives are frequently found in PP granules, and can interfere with biological tests, leading to spurious results*. The starting materials for life science products are carefully selected by BRAND so that substances that can dissolve out of the raw material (leachables), which could affect the results of biological tests, are reduced to the minimum necessary for processing. Mold release agents, such as stearates and erucic acid amide, are not used in the production process.
