[labnetwork] companies that refill ALD precursor cylinders

[DeRose, Guy A.]

Hello Jim,

As the original poster noted, Strem has halted refilling customer cylinders recently due to some internal safety concerns.  Buying new cylinders from them filled with TMA is showing a lead time into early 2024 at best. We are in a similar predicament, and are also wondering where people are refilling these days.

Best regards,
Guy

Hi Folks,

Can anyone recommend a company that will refill used ALD precursor bottles with the original chemical? We normally use Strem for this purpose, but I was just informed that they have put a stop of indeterminate length to accepting used cylinders from customers, while they review their procedures. It was suggested that I check back in a month to see where things stand, but we cannot afford to wait that long, and I would really like to avoid that extra thousands of dollars it would cost to have to buy replacement precursors in new bottles (which have a nearly one month lead-time through Strem).

I look forward to your replies.

Thank you,
