Easy-to-use detector for molecular weight determination

⇤ NEWS | 14th August 2025

The BI-MwA Molecular Weight Analyzer from TESTA Analytical is a compact, pre-aligned static light scattering detector for labs looking to quickly determine the absolute average molecular weight of any macromolecule.

Designed for educational facilities and labs running limited number of samples without the hassle of a full GPC/SEC system, you can be productively using your BI-MwA in a short time with little training. To use, simply inject your sample into the low-volume, 7-angle flow cell. The integral high-sensitivity, low-noise CCD detector automatically collects the scattered light. Intuitive software then extrapolates the data to zero angle to enable precise molecular weight determination.

The novel vertical flow path of the BI-MwA avoids trapped bubbles – a problem commonly associated with other multiple angle light scattering systems. The flow cell inside the detector has no sharp corners, only conical shapes, meaning previously analyzed samples are easily flushed out, eliminating the possibility of contamination from previous samples.
