Corning® CoolCell® freezing containers use a combination of uniform-density cross-linked polyethylene foam, a solid state core, and radial vial symmetry to create freezing profiles that are consistent and
reproducible (left). Corning® polypropylene cryogenic vials are available in a number of styles and can withstand
temperatures to -196˚C (right)
permanent sample identification, ensuring a reli- able chain of custody. These cryogenic vials are temperature-resistant polypropylene, withstanding temperatures down to -196˚C, and are compatible with most scanning and capper/decapper systems. The company also offers cryogenic vial grippers featuring a unique gripper design that allows vials to be easily sorted or moved while maintaining sterility and protecting fingers from frozen vials, dry ice and liquid nitrogen (Figure 15).

LabElite I.D. Reader with ColdScan technology from Hamilton Storage
The LabElite I.D. Reader with ColdScan technolo- gy from Hamilton Storage (www.hamilton-stor-
age.com) provides fast and accurate sample identi- fication directly out of a freezer. This maintains sample integrity without compromise from the sur- rounding environmental temperature, and also
prevents the risk of identification errors due to fog build-up on the scanning platform. Whereas pas- sive anti-fog methods coat the scanning surface with an anti-fog spray which may lose effectiveness over time, ColdScan is an active and permanent method to combat fog and condensation on the barcode scanner. The I.D. Reader automatically decodes 2D barcoded tubes, with optional 1D bar- code capability, on a wide variety of tube racks, including honeycomb-shaped racks. In addition to improving manual sample identification and track- ing, LabElite I.D. Reader is an ideal complement to Hamilton Storage’s robust and user-friendly auto- mated sample management solutions, for further efficiency in sample storage, identification and tracking workflows. For small-scale sample stor- age, Hamilton Storage SAM HD offers +4˚C, -20˚C, -40˚C and -80˚C models, and capacity up to 60,000 tubes in standard racks, or 86,250 tubes using high-density RackWare® racks. Verso® is suitable for medium- to large-capacity storage needs, with temperatures from ambient to -20˚C, and processing rates up to 1,500 tubes/hour or 170 plates/hour. Finally, Hamilton Storage BiOS® is specifically designed to store sensitive biological samples at -80˚C, with capacity from 100,000 to more than 10 million samples, and support for a wide variety of labware (Figure 16).
Labcon North America (
www.labcon.com), the world’s leading manufacturer of Earth Friendly® laboratory consumables, has developed a new family of MEMS-enabled consumables initially targeted for cryogenic applications. Labcon is now offering these feature-rich consumables in a variety of form factors such as cryovials, cen- trifuge tubes and multi-well microplates. The first iteration of the technology enables Labcon
