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.

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
