20PCS 50-Well Centrifuge Tube Rack for 15ml Vials - Sturdy Blue Rack

Our review looks at the 20PCS 50-Well Centrifuge Tube Rack for 15ml vials and explains why this modest lab accessory is valuable for routine sample handling. Designed for labs that process many mid-size tubes, the pack of detachable blue racks keeps tubes upright and organized while offering chemical resistance and autoclave tolerance. The single biggest reason to buy is simple: these racks combine a 50-well capacity with a numeric grid and a sturdy, autoclavable construction that protects samples without costing much, making them practical for everyday laboratory work.

Key Features

• 50-Well Capacity: Holds up to 50 tubes with 0.66in (17mm) diameter wells so common 15ml style vials fit securely.
• Numeric Grid: Molded numeric grid enables fast tube identification and reduces labeling errors during experiments.
• Chemically Resistant Material: Made from high strength plastic that resists alcohols and mild organic solvents for routine lab use.
• Autoclavable: Stable from -20C to 121C so racks can be autoclaved with tubes for sterile workflows and safe storage.
• Detachable Design: Simple plastic detachable stand snaps together and separates quickly to adapt to different bench layouts.
• Sample Security: Sturdy layout keeps tubes upright and spaced to prevent collisions and reduce spill risk.

Who It's For

This product suits small labs, teaching facilities, and research groups that regularly handle 15ml-style tubes and need low-cost, reliable tube organization. The numeric grid and 50-well layout are useful where multiple samples must be tracked across short protocols.

Those who require racks for unusually large-diameter tubes, heavy industrial solvents, or specialized racks with lids and locking features should look elsewhere, since this rack is optimized for standard 0.66in diameter vials and general laboratory solvents.

Pros & Cons

Pros

• Compact 50-well layout with molded numeric grid speeds identification and organization.
• Durable plastic construction resists alcohols and mild organic solvents for everyday use.
• Autoclavable up to 121C, allowing sterilization alongside tubes for contamination control.
• Detachable, quick-to-assemble design makes storage and setup fast and flexible.

Cons

• Wells are sized for tubes under 0.66in diameter so larger vials will not fit.
• Plastic finish is functional but not padded, so extremely fragile tubes still require cautious handling.

Frequently Asked Questions

Will 15ml centrifuge tubes fit this rack?
Yes, the wells are 0.66in (17mm) in diameter and accommodate tubes less than 0.66in across, which includes common 15ml-style vials.

Can these racks be sterilized in an autoclave?
Yes, the racks are rated stable from -20C to 121C and can be autoclaved with tubes for sterile storage and handling.

Is the rack resistant to common lab solvents?
The high strength plastic is chemically resistant to alcohols and mild organic solvents suitable for routine lab use, though not for aggressive chemicals.
