Product feature

Comprehensive algae information:

Countstar® BioMarine can automatically calculate the concentration, major axis length and minor axis length of algae and generate the algae growth curve, reflecting the growth of the algae.

Wide range compatibility:
Countstar® BioMarine is applicable to different shapes (i.e., spherical, elliptic, tubular, filamentous and cateniform) of unicellular and multi-cellular algae with axis length ranging from 2 µm to 180µm.

Wide range compatibility

Convenient screening:

Countstar® BioMarine can screen target algae from complex samples for classification and counting by sizes or shapes.

Convenient screening

Biomass Calculation:
To know the biomass of algae is basic for algae research. The traditional methods for analyzing biomass are Determination of the content of chlorophyll A – Accurate but complicated and time-consuming procedure. Spectrophotography – Need to use supersonic to destroy algae, not stable result and time-consuming.


Algae Biomass Calculation

Accurate and Excellent Reproducibility

Compared with the traditional hemocytometer, the result acquired by Countstar BioMarine shows a better linearity and a wider concentration range, and is thus more accurate.

Accurate Reproducibility - better linearity and wider concentration range.

Standard deviation shows Countstar BioMarine can accurately count selenastrum bibraianum cells; the error bar shows the average standard deviation.
