Never thought I would have to warn people about something. But Sambo Creek is completely dishonest and selling equipment they know will release stainless nano particles into Ice water hash solution. Stainless will pit before a Ti horn will. And Ti horns are known to pit after a few hundred/thousand hrs of use.
Your device will directly expose consumers to stainless steel nanoparticles into their hash/rosin final product using a stainless sonication horn while washing.
This is a safety concern, not venting.
I don’t even compete with your business.
We do risk management, compliance, and facility buildouts.
This is an excellent topic because ultrasonic-assisted ice hash processing can increase yield to a worthwhile degree.
It is absolutely true that sonotrodes used for food processing should be titanium. And I’m surprised their sonotrode is stainless steel.
New processing methods (adding other metals) for SS sonotorodes (mainly for ultrasonic welding) significantly increase their cavitation corrosion resistance, but they are toxic in foods.
The issue of metal particle release over time is much worse than that for Ti and SS. But at least in water with Ti sonotrodes in operation for 7.5 hours at 18 and 20 kHz, no nano-sized particles (<80 nm) were found on a two-dimensional basis. Yet significant micron-sized particles were found. And metal leaching into water was found when using SS process tanks (below a safe level threshold in water).
This study considering the safety of ingested food (and liquid), found no major health concerns regarding nano-particles from lower frequency sonotrodes. Still, there is a concern with significant micro-particles.
I’m sure inhaling metal particles is a significant health concern. But I wonder how many particles would end up in rosin. And how many would be inhaled by combustion and vaporization methods using rosin or kief, versus how many would remain in resin, ash, water (e.g., bong), etc.?
I also wonder how many particles would remain on trichomes after sieving with mash bags and washing.
