The 2-mL scale miniature bioreactor, capable of both continuous perfusion and fed batch processes, aims to expedite and simplify two broad applications.
Recent studies on biotherapeutic protein production have shown perfusion processes as a superior technology vs. the traditional batch and fed batch approaches. Due to its associated process stability and reducing effect of varying conditions inside the bioreactor, Perfusion can deliver lower production costs and higher titer, especially in the case of low titer or fragile […]
In studying COVID-19, the Iprasense CYNOTE is very well suited to BSL3 and BSL4 laboratory conditions. It allows a scientist to save time by not having to enter the laboratory, and to check results from the safety of their own home.
Spectrophotometers can be an excellent tools to monitor the growth phase or determine cell concentrations in microbial fermentation processes. Despite of the fact that these instruments are generally utilized to measure absorbance of particular samples (concentration measurements), spectrophotometers are also used to quantify light scattering running at 600 nm wavelength. This method, commonly known as […]
The latest advances in digital technologies allow users to perform a density measurement with a high degree of precision and great resolution. To maximize the accuracy of results, however, users may benefit by applying the best operating practices described in this article. Advantages of Digital Automatic Density Measurement Digital density meters typically use electromagnetically-induced oscillation […]
The Karl Fisher titration method was published to determine trace amount of water samples in non-aqueous systems that contained sulfur dioxide. It is currently the standard method used to calculate the moisture content in various products. When looking at titration analysis methods, it can be a challenge to determine which to use. This article takes […]
Ultraviolet and visible light range (UV/VIS) is widely applied in research, production and quality control for the classification and study of substances. UV/VIS spectroscopy is based on the absorption of light by a sample. Depending on the amount of light and its wavelength absorbed by the sample, valuable information can be obtained, such as the purity […]
Production of biologics based on Recombinant DNA technologies through mammalian cell culture / bacterial fermentation require precise monitoring and control of key process parameters. The glucose concentration – main carbon source – is one of the most important ones. A method for online glucose measurement has been applied and perfected during the last 15 years […]
Recombinant Therapeutic Proteins development and production operations require reliable and accurate biochemistry analyzers to characterize the cell culture process and maximize results through photometric analysis. Traditional membrane based (electrochemical) analyzers still in use in many labs present multiple problems including measurement drift and the need of high frequency maintenance. An advanced, more accurate technology based […]
