Turbidity of solutions
TURBIDI.T™ measures the turbidity of solutions over a wide range at selectable wavelengths using modular optical CARTRIDGE.S™.
The applications of TURBIDI.T™ are multiple: determining the concentration of particles, testing sedimentation profiles of particles over time, determination of solubility point of compounds, testing of particle dissolution, determination of cells concentration and activity,etc. See below some of the applications of the TURBIDI.T™ in Life Sciences.
Growing demands for quicker cell quantification methods push beyond traditional cell counting chambers, prompting innovative solutions that facilitate accurate counting while diminishing time. Turbidity, reflecting solution cloudiness in the presence of light scatterers, emerges as an effective means to accelerate cell quantification. In this application note, a strong correlation was established between turbidity (FTU) of a S. cerevisiae culture solution and cell numbers (cells/mL) counted with a conventional cell counting chamber...
In the realm of bioengineering and biotechnology, cells serve as catalysts for the production of diverse valuable products, such as biofuels, pharmaceuticals, antibodies, industrial enzymes, and bio-based chemicals [1]. Within this context, yeast, a widely utilized microorganism, plays a pivotal role. Monitoring yeast growth is of utmost importance to ensure optimal conditions and productivity in biotechnological processes [2]. Traditionally, spectrophotometric analysis has been used to assess the optical density at 600 nm (OD600nm) by measuring the absorption of light by the yeast ...
The sedimentation kinetics of suspended particles provides crucial information for optimizing manufacturing and infrastructure across industries, while also contributing to the design of drugs and cell therapies. Turbidimetry is a quick and nondestructive method to precisely determine the sedimentation kinetics of suspended particles. The decrease in turbidity of silica particles in distilled water as a function of time was obtained with high precision using the TURBIDI.TTM. This curve gives information about the sedimentation behavior and rate of the suspended particles ...
The determination of particle size is important in many fields, such as life sciences (nanomedicine, drug delivery, tissue engineering, bioanalysis), chemical, environmental sciences and industries. Turbidimetry is a quick and nondestructive method to estimate particle size following an easy-to-follow procedure. Curves of turbidity vs silica particle concentration in distilled water of various sizes were obtained with high precision using the TURBIDI.TTM. These curves can be used to build a reference curve for the determination of particle size.
A suspension is a mixture in which solid particles (organic or inorganic in nature) are dispersed in a liquid medium, but not dissolved. Suspensions are usually opaque or cloudy and can settle over time due to gravity. They have a broad range of applications and are present in various industrial processes, such as chemical, pharmaceutical, food and beverage, and environmental industries. During the production of pharmaceutical formulations for example, professionals may measure particle concentration to assess whether particles have aggregated or formed larger clusters to optimize the process and ensure product quality.
TURBIDI.T™ is a technology that accurately measures the turbidity of solutions across a broad spectrum. Its effectiveness has been tested against an established turbidimeter and the results have indicated that both technologies yield consistent measurements for formazin solutions of varying concentrations.
