eBay UK 3A Mollecular sieves, 2kg, £8.25 inc.p&p
Item # 362000869748
I am not experienced with mollecular sieves so caveat emptor,
there appear to be almost no broken beads or dust.
Adding water to c 1cm of sieves in the bottom of a test tube made the test tube too hot to hold - so I guess they are good.
This is the cheapest that I've seen 3A sieves in available in small quantities (100g min.) so I bought 2 kg,
I just mention it in case anyone else is looking for similar
