Biofine Clear A3 
Is specifically formulated for the rapid sedimentation of yeast in beer and is not derived from animal products. Biofine Clear A3 is a purified colloidal solution of silicic acid (SiO2) in water. 25 liter/55 pounds
Biocloud
Is a yeast-derived cloud system, extracted from primary grown Saccharomyces ceriviseae cells. It has been developed to give a stable turbidity to speciality beers (e.g. wheat beer types) without significantly affecting color or flavor. 33 pounds
Biofine P19
Is a refined isinglass collagen which has superior dissolution properties. When dissolved in water and added to beer it causes yeast and suspended protein to settle rapidly giving a bright supernatant beer which permits rapid filtration. At higher dose rates filtration may not be necessary. 1 pound,5 pound, 25lg/55 pounds
Magicol 250AS
This is an unrefined powdered isinglass which gives excellent beer clarity. The product takes longer to dissolve than other isinglass products but has the highest level of collagen and so for brewers prepared to invest the time to dissolve the product the clarities obtained are superb. 1kg/ 2.2 pounds

Magicol 250AC
This is a specialist isinglass blend which contains a high proportion of leaf type isinglass which gives superior clarity. It is useful for beers which are not to be filtered such as cask beer. In addition this formulation contains no sulphur dioxide and so is useful for treating beers fermented with sulphur reducing yeasts. (Beers that when fined exhibit generation of hydrogen sulphide) 1kg 2.2 pounds

Caskleer Paste
Is a paste form of isinglass which dissolves very rapidly. It has an isinglass formulation well suited to cask beers and gives superb clarity and compact sediment. Since it dissolves very rapidly may be suitable for brewers preparing the occasional cask. 5 pounds, 15kg/33 pounds

Auxiliary finings
Alginex
Is a polysaccharide based auxiliary fining agent which is used in conjunction with isinglass to produce brilliant clarity in cask conditioned beers. Alginex consists of strongly negatively charged molecules which bind strongly to positively and uncharged particles in beer. This results in the beer containing only particles possessing a negative charge. This renders all the particulate material susceptible to reaction with isinglass, (a positively charged species), and therefore a more complete reaction is obtained and brighter cask beer as a result. 1 liter
