Ballast Soil Systems for laundry testing
SBL classic

Soil Ballast 'SBL Classic', order code 10999

This was the first soil ballast system developed by wfk. The concept was based on the results of a wfk research project in the late 1980ies. Today we consider it technically outdated - we suggest to use SBL 2004 or SBL'07 instead. However, SBL classic has been used for decades and is still specified in some test protocols. It is therefore still available.

SBL2004

Soil Ballast 'SBL2004', order code 10996

The soil composition of SBL2004 is more complex than that of SBL classic. With that we managed to drive the soil ballast impact on stain removal closer to 'reality' (as established in bundle tests).

SBL'07

Soil Ballast 'SBL'07', order code 10994

This product is a slightly revised version of SBL2004. No change in concept, no significant modifications in composition. We changed the bleach consuming component (mainly for reasons related to our production), and additionally aimed at fine tuning the performance characteristics.
