[. . . ] Directly suck the suspension into copper tubes (inner ø 350 µm) already mounted in their holder. Alternatively, take up sample into cellulose microcapillary. With the loading device the specimen can be inserted into the EM PACT. After cryofixation the samples are stored under LN2 in the transfer box. Sample Punch: punching out of the central part of the specimen tube ready for Frozen Hydrated Sectioning or . . . . . . peeling away of the top of the copper tube for Freeze Substitution. Storage of the copper tubes is carried out under LN2. The specimen tube holders are recycled by reloading them with copper tubes. Leica Design by W. Hölbl 7 Leica EM RTS Application Solutions Taking microbiopsies for EM is now faster than ever before!Prepare the Microbiopsy Transfer Station for RTS under the Optical Workstation. . . before taking a biopsy with the biopsy gun. Insert the biopsy gun into the transfer station . . . . . . and transfer the tissue into the biopsy carrier. The specimen and carrier are held in the rapid loader . . . . . . while the primed loading device waits for freezing in the RTS. By gently pushing the rapid loader into the RTS the carrier is tightened securely and then frozen automatically in less than 2. 5 seconds. After cryofixation the carriers are collected in the LN2 bath of the EM PACT2 before freeze substitution in the Leica EM AFS2 or cryosectioning in the EM FC6. 8 Frozen Hydrated Sectioning made easy. Alternatively, the carriers can be trimmed with a cutter . . . . . . for Frozen Hydrated Sectioning in the cryoultramicrotome. All necessary steps for follow-on procedures (eg. Freeze Substitution) can be conveniently performed in the cryopreparation box supplied with the Leica EM PACT2. The Freeze Fracture Holder for everything that can be fractured . . . Prepare the Freeze Fracture Station under the Optical Workstation . . . and preload the freeze fracture carrier.
