MODERN LABORATORY AND INDUSTRIAL LAB INSTRUMENTS

Absorbance is a crucial concept in the field of spectrophotometry, a technique used to measure the amount of light absorbed by a substance over a large range of wavelengths. It is a dimensionless quantity derived from the logarithm of the ratio of incident light to transmitted light through a sample. The absorbance spectrum, often represented as a graph, reveals the wavelengths at which a substance absorbs light most strongly (Figure 1). This information is useful in various scientific fields such as biology, chemistry, biochemistry, molecular biology for identifying and quantifying specific compounds...

The mechanical characterization of biological soft membranes such as skin, pericardium, or hydrogel-based samples is challenging and often results in sample damage. The Membrane Sample Holder of the ElastoSens™ Bio has been designed for facilitating the loading and the handling of membrane samples allowing proper mechanical testing. In this study, the elasticity of bovine pericardium membranes were precisely measured using the ElastoSens™ Bio...

Enzymes are commonly used in the field of regenerative medicine to degrade native tissues for the extraction of cells and other components, or as a part of physiological-like fluids to mimic in vivo conditions for biomaterials in development. The performance of enzymes can be measured in terms of weight loss or mechanical properties. The viscoelastic properties of kidney tissue during incubation with collagenase was precisely measured using the ElastoSens™ Bio...

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. Utilizing TURBIDI.T™ for accurate turbidity measurements offers a user-friendly...
