Globe Scientific Reversible Microcentrifuge Rack - 80/96-Place, PP, PACK/5, 8 Colors

A reversible rack provides two working configurations in one physical unit — flip it to access the second tube size without swapping racks. Globe Scientific's Reversible Microcentrifuge Tube Racks hold 1.5mL and 2.0mL tubes in one orientation and 0.5mL tubes in the reverse, covering the full range of common microcentrifuge tube formats with a single rack design. Available without cover (456350, 80-place, PACK/5 at $69.10) and with cover (456355, 96-place, PACK/5 at $117.70) for applications requiring tube containment during transport, freezer storage, or biosafety cabinet work.

Both configurations are constructed from polypropylene (PP), autoclavable, and available in 8 colors — Blue, Clear (Natural), Green, Orange, Pink, Red, Yellow, plus Assorted packs — all at the same price within each configuration. The 5-pack format makes per-unit cost efficient for labs that need to stock multiple racks of the same type, and the assorted color option provides immediate variety for labs setting up color-coding systems from scratch.

Features and Benefits

• Reversible Design — Two Tube Sizes, One Rack: Flip orientation to switch between 1.5mL/2.0mL configuration (one face) and 0.5mL configuration (reverse face), eliminating the need to stock separate rack types for different microcentrifuge tube sizes in the same lab.

• Without Cover (456350) and With Cover (456355): The 456355 with cover adds a translucent lid that allows viewing tube contents while containing tubes during transport, biosafety cabinet work, and freezer storage — the cover prevents tubes from dislodging when the rack is moved or inverted for the reverse tube size.

• 8 Colors Including Assorted Pack: Blue, Natural, Green, Orange, Pink, Red, Yellow, and an Assorted 5-pack — the assorted option provides immediate color variety for labs establishing new color-coding systems without having to order each color separately.

• PACK/5 Format for Cost-Efficient Restocking: 5-packs reduce per-unit cost versus individual purchases, appropriate for labs that consume multiple racks per experiment or maintain a standing stock of colored racks for batch coding.

• PP Construction, Autoclavable: Polypropylene resists standard lab chemicals and can be autoclaved between sample runs for decontamination — supports both standard bench use and sterile technique workflows requiring equipment decontamination.

Laboratory Applications

• Labs using both 0.5mL and 1.5/2.0mL microcentrifuge tube formats where a reversible dual-configuration rack eliminates the need to maintain separate rack inventories for each tube size

• Biosafety cabinet and transport applications where the 456355 with translucent cover contains tubes during rack movement, preventing dislodging when the rack is handled in confined spaces or moved between instruments

• Freezer storage organization where the covered 456355 keeps tube sets contained and labeled in -20°C or -80°C storage, with the translucent cover allowing contents identification without opening

• High-volume labs restocking rack inventory where PACK/5 pricing and assorted color packs reduce ordering complexity and provide immediate variety for color-coded batch organization systems

Frequently Asked Questions

How does the reversible design work?
The rack is molded with two different tube-hole configurations on its two faces — one face accepts 1.5mL and 2.0mL tubes, the opposite face accepts 0.5mL tubes. To switch between tube sizes, simply flip the rack over. The tube positions are sized correctly on each face for their respective tube diameter, providing secure tube retention in both orientations.

Which configuration should I order — 456350 (no cover) or 456355 (with cover)?
If you only need bench organization, the 456350 at $69.10/PACK/5 is the cost-effective choice. If you need to contain tubes during transport, biosafety cabinet use, or freezer storage where tube dislodging is a concern, the 456355 at $117.70/PACK/5 adds the translucent cover. The cover also allows visual contents check without opening, which is useful for sample retrieval from a populated freezer rack.

What does "AST" (Assorted) include?
The AST suffix indicates an assorted pack containing a mix of available colors — 5 racks per pack, each a different color. The specific color assortment may vary by production batch. If specific colors are required for an established color-coding system, order by individual color SKU instead.
