SB50 mk2 – USB Powered Colloidal Silver Generator with Current Limiting and Electronic Stirring


A great value generator with electronic stirring, ideal for producing Colloidal Silver. USB powered and super compact measuring only 97mm x 58mm x 40mm makes this a real ‘take anywhere’ unit.

SKU: SB50-1 Category:


This Microprocessor controlled, USB powered unit is the ideal generator for the user who wants to produce quality Colloidal Silver with minimal effort. The electronic stirring is achieved using ion flow by current reversal. This allows batches to be produced without the normal residue produced by static water. It has everything that is needed to get you started including the USB Power supply.

As with all Silver Bear products, this is a professionally engineered unit with a machined aluminium case , Power and Busy indicator LED’s, 35v DC to DC Converter,  Current limiting and electronic Stirring. The current is variable from 1.5mA up to 10mA to allow a wide rangle of electrodes to be used. Supplied electrodes work well at around 2mA. It also has a DC motor drive output for motorised electrode holders if required. The electrodes can be fitted into the socket on the top of the unit or you can also use the jack socket on the side to connect an alternative electrode holder such as our mason jar adapters or motorised adapters.

All you will need to provide is a Mason Jar or any other glass jar to contain the distilled water. The unit does not use any batteries and instead uses electronic inverter technology to boost the 5v USB power to the 35v required to make colloidal silver.
