The RD sampler is designed with full bore which make the RD sampler with the capabilites that retained after the tool has trapped its sample. Several samplers can be run on the same time in downhole and a test to allow sampling at different times. The rupture disk in the sampler is controlled by annulus pressure. The operation pressure of RD sampler is certain and steady which controlled by high precise rupture disks. One time operation, once the RD sampler is closed can not be open again, several samplers can be run on if different testings needed.
