Globe Scientific Reversible Microcentrifuge Tube Rack with Cover (456355 series) holds 96 tubes on each side — 96-place for 1.5mL and 2.0mL tubes on one side, 96-place for 0.2mL and 0.5mL tubes on the reverse. The included snap-on cover is what separates this model from the coverless 80/60-place version (456350 series). The cover protects tubes during transport between labs, prevents contamination during storage in shared freezers, and stops tubes from popping out when the rack is carried or stacked.
The Cover Changes How You Use the Rack
A coverless rack is a benchtop tool — you grab tubes in and out freely during active work. A covered rack is a storage and transport tool — samples go in, the lid closes, and the rack moves to the freezer, across the hall, or to another lab without risk of losing tubes, contaminating samples, or spilling contents. In biobank environments where racks move between -80°C freezers, processing benches, and shipping containers, the cover is not a convenience feature — it is a containment requirement that prevents sample loss and cross-contamination during every transfer.
Equal 96-Place Capacity on Both Sides
Unlike the 80/60-place reversible rack where the two sides have different capacities, this 96/96-place model provides identical positioning regardless of which side faces up. This matters for inventory tracking — one rack always equals 96 positions, no mental math about which side is which. For laboratories that work heavily in 96-well plate formats (high-throughput screening, PCR workflows, combinatorial chemistry), having tube storage align with the 96-well standard simplifies sample organization and tracking across tube and plate formats.
Autoclavable PP for Full Temperature Range
The polypropylene construction handles the entire laboratory temperature range: autoclave sterilization at 121°C down to -80°C freezer storage. The cover material matches the base — both autoclave as a single unit. PP remains impact-resistant and dimensionally stable across this temperature range, unlike polystyrene (shatters when frozen) and acrylic (warps under heat). Chemical resistance to laboratory solvents and cleaning agents allows thorough decontamination between sample sets.
8 Colors for Organized Storage
Available in 7 individual colors (blue, natural, green, orange, pink, red, yellow) plus an assorted pack. In freezer storage systems where dozens of racks occupy the same shelf, color is the fastest identification method — faster than reading labels through frost, faster than pulling racks to check contents. Assign colors to projects, patients, time points, or researchers and find the right rack in seconds.
