Frequently Asked Questions
Can these racks be autoclaved for reuse?
Yes — polypropylene copolymer is autoclave-compatible, making these racks suitable for repeated sterilization cycles in reusable rack programs. Allow the rack to cool completely before reloading tubes.
What does "unassembled" mean, and how difficult is assembly?
The rack ships flat or in knocked-down form to reduce shipping volume and storage footprint. Assembly requires no tools and takes only moments; the format also allows the rack to be disassembled for compact storage or transport when not in use.
Why choose a red rack specifically?
Red is widely used in clinical and research labs as a visual cue for STAT, priority, or categorically distinct specimen sets. Color-coding racks by assay type, urgency, or department reduces the risk of sample mix-ups in busy multi-rack workstations.
