Alkazyme enzymatic is for the thorough cleaning-pre-disinfection of all reusable, immersible dental instruments prior to autoclaving. It has a rapid cleaning action; when used in conjunction with an ultrasonic cleaner a minimum five minute contact time is all that is required to render used instruments thoroughly clean and shining bright. Alkazyme is also economical: just 5 g of Alkazyme with ordinary tap water makes 1 litre of enzymatic cleaning/disinfecting solution. Alkazyme is available from your usual dental sundry supplier in both 750 g loose powder and tubs of 100 easy dose water soluble sachets. www.alkazyme.com
