Do you know exactly, how "hungry" the micro biology in your biogas fermenter actually is?
With our FOS/TAC Titration Kit you will get a daily useful indicator for this!

The components "Haushaltssieb und Schüssel" shown above are not longer included in the laboratory kit since 01.08.2015, due to technical reasons of shipping. Our customers are kindly asked to buy those components by themselves to their convenience for completion and for appropriate performance of the titration.

The FOS/TAC-value for your smart daily feed control

To meter the FOS/TAC value daily you will need only an appropriate titration laboratory (like ours) and about 20min/d of time.

Each biogas operator will learn this method easily. If necessary we will support you also in your first practice by phone or even on-site (extra fees, of course).
A comprehensive user manual with all you should know about practicing FOS/TAC is contained in the Kit and should usually leed you through all your learning exercises, as well as an (well layouted for printout) EXCEL computer spreadsheet for easy, automatted calculation of the FOS/TAC values from the measurement values you inserted before.
Available also in English for our foreign customers!

EC (Electric Conductivity) measurement as supplement parameter in biologic process control

EC measurement (in mS) of your biogas substrate supplements the FOS/TAC titration as indicator. Thus, you control the salinification of your substrate (as an approach for the NH4-content in your system) and at same time the danger of inhibitation of the biogas process by rising pH values, and most important, by the increasing amount of most toxic cell poison, ammonia gas (NH3).

How to order?

Just fill in the order form (download is on top of this page), sign it and send it per fax or Email (as scan) to us.

In case of urgent orders we strongly recommend to first check with us the actual shipping time via Email. Sometimes it may take a few days, if not all of the numerous components contained in the kit are in stock.

Terms of supply of our "FOS/TAC titration Kit":
Shipping is also possible outside Germany and abroad!

We will also ship the FOS/TAC Titration Kit within EU countries. Only the minor additional shipping costs (usually not more than 20,- EUR) are to be payed extra.
For billing excluding VAT we obligatory need your valid VAT number indicated in your order.

For shipping to non-EU countries we also have to bill all customs expenditures. If this applies: Please ask us by Email before ordering about this additional costs and feasibility of the delivery. Actually we have experiences with export for example to Canada and Switzerland.

Unfortunately we made some bad experiences the last years with customers:
Thus, shipping to all destinies outside Germany is only processed after prepayment.

We will answer any request for order by email also in English language!

We wish you good success with our "FOS/TAC Titration Kit"!
