Hi Zhijie,
This loop is good if you have a long unit cell on one dimension and you can align your crystal in a particular direction. You basically need a beamline equipped with Kappa, which allows you to directly put the crystal on with the plastic tube. A normal cryotong does not hold the bent loop.
Regards,
Weikai

Subject: [ccp4bb] Hampton's adjustable cryoloop
Hello,
I just noticed that Hampton Research carries this adjustable mounted cryoloop (HR5-900):
http://hamptonresearch.com/product_detail.aspx?cid=24&sid=136&pid=385<wlmailhtml:{35C92305-260C-4820-B40D-05B0D91A0A8F}mid://00000065/!x-usc:http://hamptonresearch.com/product_detail.aspx?cid=24&sid=136&pid=385>
This looks quite interesting to me, as it seems that not every synchrotron station's configuration can allow the use of an extended arc.
I wonder if somebody here can share some insights or experiences about this adjustable cryoloop. I once tried to bend my non-hollow stainless steel pin in liquid nitrogen with tweezers. It didn't work - the pin was too stiff then I lost my crystal in the end. I wonder if this cryoloop was designed such that bending it would be easier.
Thanks in advance!
Zhijie
