VIT® 021N/Thiothrix

Test kit for rapid identification and quantification of the
filamentous sulfur bacteria Eikelboom Typo 021N and Thiothrix

Item Number: 01110007

Detection of filamentous bacteria

VIT® 021N/Thiothrix specifically detects Eikelboom Type 021N as well as Thiothrix bacteria directly within your wastewater sample. These bacteria are considered causing bulking sludge in wastewater treatment plants. By means of our VIT® key, contained bacteria can be quantified. Changes within one population can thus be monitored continuously.

By integrating our product into an early warning system you will save a considerable amount of chemicals.

The analysis is easy to conduct – only few minutes hands-on time. VIT® analysis is directly made on an aliquot of the sample material. The results are provided within 3 hours. Analysis is performed by using a fluorescence microscope. All essential consumables required for analysis are contained in the kit. Package size: 25 analyses.
