Composition and physico-chemical properties of FeSSIF-V2

An improved Buffer Concentrate for preparation of FeSSIF-V2 has been developed to overcome the limitations of the previous maleic acid buffer system. It has similar properties but enables easier medium preparation with better chemical stability as well as low variability.

Composition and physico-chemical properties of FeSSIF-V2

Media preparation

FeSSIF-V2 medium has been prepared using FeSSIF-V2 Powder and the buffer prepared from scratch. The current improved FeSSIF-V2 medium has been prepared using FeSSIF-V2 Powder and FaSSIF-V2 Buffer Concentrate. Physico-chemical properties have been tested, for 48h, for both media.

Physical parameters after preparation

FeSSIF-V2 prepared using FeSSIF-V2 Powder with Buffer Concentrate and FeSSIF-V2 prepared using FeSSIF-V2 Powder with buffer from scratch have very similar physico-chemical properties (pH, surface tension and buffer capacity). These properties remain stable for at least 48h. FeSSIF-V2 made using FeSSIF-V2 Powder and FeSSIF-V2 Buffer Concentrate is an easy, efficient and reliable preparation method.
