A CT scan of Stanley’s viral Quencher cup has confirmed what the firm has been saying all alongside: There’s handiest lead at the bottom of the cup.

The team at Lumafield, a hardware manufacturing firm that makes CT scanners, ran Stanley’s Quencher tumbler thru one in all their machines remaining week. While videos of certain outcomes from at-dwelling lead assessments (which professional warn can even be unreliable) maintain resulted in never-ending speculation over what parts of the cups maintain lead, Lumafield’s CT scan confirmed that there became handiest lead at the bottom of the Stanley Quencher.
The lead identified by Lumafield, which is distinguished by the darkish crimson circle on the CT scan, is the lead pellet historic by Stanley to solder its cups. Stanley’s tumbler cups function an inner and outer wall fabricated from stainless metallic that is welded together at the rim. Between these partitions is a vacuum of insulation, which is what minimizes heat switch and helps maintain your beverage warm or chilly.
Stanley says it uses a lead pellet to seal the vacuum insulation at the bottom of the cup. The firm then covers the lead pellet with a stainless metallic disk, the same topic materials historic for the remainder of the tumbler.
So, what does this CT scan insist us? First, it capacity that Stanley wasn’t lying: There became handiest lead at the bottom of the tested cup. Nevertheless that doesn’t mean that folk with Stanley cups are fully safe from lead exposure, which is able to motive severe successfully being complications for teenagers and adults.
“[O]ur CT defective-portion reveals that the lead is fully shielded, and its user won’t be uncovered to lead in any appreciate. If the medallion covering the lead solder is pried off, it would also turn into accessible—but in that case, a replacement cup is coated by Stanley’s guarantee,” Jon Bruner, Lumafield’s head of marketing, talked about in a post on X.
The keyword here is the medallion, or the stainless metallic disc covering the lead. In other phrases, whereas the CT scan clearly confirmed us the place the lead in Stanley’s cups is, it also confirmed us that the handiest thing protecting folk from exposure is a runt metallic disc that could presumably theoretically fall off or turn into unsealed.
Lead security activist Tamara Rubin informed Gizmodo in February that she’s acquired a full bunch of reports of folk stating that their vulgar cap has fallen off after customary train.
“In the remaining couple of days by myself, I’ve had something address 300 folk contact me and insist me that that disc on the bottom of their Stanley’s fell off within a week or a month of traditional train,” Rubin talked about, adding that if folk touch the lead pellet inside their cups and then touch food, they could presumably repeat themselves to lead.
Stanley, for its portion, states that the stainless metallic duvet coming off is “a uncommon prevalence.”
While consultants remark there isn’t any threat to using Stanley cups that are in ideal situation, develop you undoubtedly desire to steal the threat? There are masses of assorted cups, corresponding to Stanley’s lead competitor Hydro Flask, out there that don’t contain lead. (To be beautiful, Hydro Flask historic lead in its cups till it invested in going lead-free.)
“As patrons turn into extra discerning about the merchandise they buy, the stress on corporations to not compromise on security or sustainability will handiest increase,” Lumafield wrote in a post about its experiment.
We’re looking at you, Stanley.
