A California company is announcing this week that it has developed a new vape cartridge design that protects the cannabis oil inside from any contact with metal parts.

Gino Ajodani, the president of the firm, tells High Times that the cartridge is constructed from high-heat PETG plastic that is proven to be free of arsenic, cadmium, lead, and mercury. Under California state regulations, cannabis products must be lab tested and meet standards for the presence of those four heavy metals before entering the retail market.

Ajodani says that the only metal part in the MF-1000 is its titanium heating coil. To prove that the metal-free cartridges actually contain no heavy metals, Global Meds Outlet took them to a cannabis testing lab to be analyzed. But no test procedure for testing hardware was in place, so Infinite Chemical Analysis Labs in San Diego developed one that used a concentrated nitric acid solution to break down the cartridge.

“They tested the nitric acid for heavy metals first,” Ajodani explains. “Then they dissolved the entire cartridge in the nitric acid, and then they tested the solution again.”

That analysis determined that the MF-1000 had no detectable levels arsenic, cadmium, lead, or mercury. To further validate the results, Ajodani says tests of filled cartridges revealed that cannabis oil was free of heavy metals after seven and 14 days in the cart. Global Meds Outlet plans to continue the testing for cartridges that have been
