[3dem] exchange of zeolite in a Gatan 626 cryholder

[Robert McLeod]

Lubomir,

Molecular sieve sorbents are commonly used in foreline traps for systems with oil-lubricated rotary-vane roughing pumps and similar.  You just want to know where to buy it?  I.e. Kurt J. Lesker offers a 1 lbs. can here for 23 Euros:

The main issue might be grain size.  Foreline traps are fairly large.  I guess one could always grind the pellets down with a mortar and pestle or a ball mill, or look for another vendor

Subject: [3dem] exchange of zeolite in a Gatan 626 cryholder

Dear colleagues,

I wonder if it is possible to exchange the zeolite powder in the Gatan
cryoholder in the lab and avoid sending it to the company. I I hoped to
google out a recipe but I could not find one. Has anyone tried this?

With best regards,

Lubomir
