MUHWA 100-Place Centrifuge Tube Rack Box — Organized Storage for Every Lab
The MUHWA 100-position centrifuge tube rack box is a durable polypropylene storage solution engineered for busy research and clinical laboratories. Accommodating up to 100 microcentrifuge tubes across a range of sizes (0.5 mL to 2.0 mL), this square-format box combines a transparent lid for instant sample visibility with an alphanumeric grid for systematic inventory tracking. Autoclavable and freezer-safe, it replaces fragile cardboard freezer boxes with a reusable, stackable alternative built for daily lab workflows.
Key Features
- 100-Position Capacity: Dense 10×10 grid maximizes storage in a compact footprint; holds 0.5 mL, 1.2 mL, 1.5 mL, and 2.0 mL microcentrifuge tubes.
- Autoclavable at 121°C: Virgin polypropylene withstands repeated steam sterilization (250°F / 15 psi / 20 min) without warping or degradation.
- Transparent Lid: Crystal-clear cover allows visual confirmation of tube presence and sample status without opening the box; reduces temperature fluctuation from repeated lid removal.
- Alphanumeric Grid Indexing: Numbered rows (1–10) and lettered columns (A–J) for precise sample location tracking; compatible with lab notebook and LIMS documentation.
- Freezer-Safe to -80°C: Maintains structural integrity in ultra-low temperature freezers; resists cracking and embrittlement during freeze-thaw cycles.
- Chemical-Resistant: Inert to common laboratory reagents, alcohols, and mild acids; suitable for routine bench use.
- Stackable Design: Square profile with stable stacking for space-efficient freezer and cold-room organization.

FAQ
Q: What tube sizes fit in this box?
This box accommodates 0.5 mL, 1.2 mL, 1.5 mL, and 2.0 mL microcentrifuge tubes — both conical-bottom and skirted styles. The 10×10 grid wells are sized for standard microcentrifuge tube diameters.
Q: Is the lid removable or hinged?
The lid is fully removable, allowing unobstructed access to all 100 positions during busy workflows.
Q: Can this box be autoclaved with tubes inside?
Yes, the polypropylene construction is autoclavable. Remove the lid during autoclaving for proper steam penetration. Tubes should also be rated for autoclave conditions.
Q: How does this compare to cardboard freezer boxes?
Unlike single-use cardboard boxes that degrade with moisture and repeated freezing, this PP box is reusable, autoclavable, and chemically resistant — offering better long-term value and sample protection.
