We recommend that you use the  Hampton CrystalCap Magnetic™ and vial system with 22mm fixed sample 
	  holder length (18mm pins) and presents a 10-character identification code (data matrix on the basis of the caps + clear 
	  node near the data matrix or on the rim of the cap). The complete system is marketed as the Hampton 
CrystalCapHT™. 
	  The system includes vials, caps and loops. It is 
important to keep the 
loop to crystal 
	  size proportional to reduce background scatter and ease of crystal visualization for crystal centering. 
	  When shipping samples 
include an empty loop to prepare the sample environment correctly on the beamline.
