Centrifuge Tube Storage Boxes
Description
Product Positioning
Hawach Centrifuge Tube Storage Boxes are designed as a standardized laboratory sample organization system.
In most labs, the real problem is not the tubes themselves, but how quickly storage setups become inconsistent once workflows scale or multiple people start using the same freezer space.
This system is meant to reduce that drift.
They are available in three configurations:
- Single-Format PP Boxes (one tube size per box)
- Dual-Compatibility PP Boxes (0.5 mL + 1.5 mL together)
- Cardboard Boxes (short-term handling or transport use)
Nothing complicated-just a way to keep sample storage predictable over time.
10-Second Selection Guide
| IF YOUR WORKFLOW REQUIRES… | YOU SHOULD USE… | WHY |
| Only one tube size in daily use | Single-Format PP Box | Simple, stable fit, no adjustment needed |
| Both 0.5 mL and 1.5 mL tubes | Dual-Compatibility PP Box | One box instead of managing two systems |
| Long-term -80°C freezer storage | PP Boxes | Handles cold storage without warping issues |
| Short-term storage or sample shipping | Cardboard Box | Lightweight and cost-efficient |
| Sterile PCR or cell culture work | Autoclavable PP Box | Can be sterilized before use |
Core Problem – Solution Mapping
What we usually see in labs
- Tubes end up spread across different rack systems
- Different people label things differently (or not at all)
- Cardboard boxes slowly deform in cold rooms or freezers
- Freezer space becomes messy over time, even in well-managed labs
What this system is trying to solve
- A consistent indexing grid that stays readable
- A rigid PP structure that does not deform in cold storage
- One platform that works across multiple tube sizes
- Standard footprint so freezer organization doesn’t drift
Decision Impact Table
| Problem | Solution | What actually improves | Impact |
| Sample mix-ups in freezer | Alphanumeric grid system | Faster and more reliable retrieval | High |
| Cardboard deformation at -80°C | Rigid PP structure | Stable long-term storage | High |
| Too many tube formats | Dual-compatibility design | Fewer storage systems to manage | High |
| Limited freezer space | Stackable flat-top design | Better space utilization | Medium |
| Sterility requirements | Autoclavable PP (121°C) | Reduced contamination risk | High |
Product Architecture
1. Single-Format Centrifuge Tube Storage Box (PP)
This is the most straightforward version-one tube size per box.
It’s typically used in labs where workflows are consistent and people don’t mix tube types in the same experiment area.
Available SKUs
| SKU | Tube Size | Wells | Material |
| 11321004 | 0.2 mL PCR tubes | 96 | PP |
| 11321005 | 0.5 mL microtubes | 72 | PP |
| 11321006 | 1.5 mL microtubes | 72 | PP |
| 11321007 | 5 mL tubes | 32 | PP |
Key Features
- Each well is molded for a single tube diameter (no loose fit issues)
- Hinged lid with snap closure-holds up during transport
- Frosted labeling area (useful when things sit in freezers for months)
- Works from -80°C up to 121°C autoclave cycles
- DNase/RNase-free option available if needed
2. Dual-Compatibility Centrifuge Tube Box (PP)
This version is designed for labs where 0.5 mL and 1.5 mL tubes are used side by side-which, in practice, is most molecular biology workflows.
Instead of buying two separate systems, this combines both.
Available SKUs
| SKU | Compatibility | Wells | Material |
| 11321008 | 0.5 mL + 1.5 mL | 60 | PP |
| 11321009 | 0.5 mL + 1.5 mL | 96 | PP |
Key Features
- Stepped or tapered wells that naturally center both tube sizes
- Reduces duplicate storage systems (less rack confusion in shared labs)
- Typically cuts SKU management by about half in mixed workflows
- Same PP structure as single-format boxes (no compromise on durability)
- Works well in high-density freezer setups where space matters
In practice, this is usually the version labs switch to once they get tired of managing two parallel systems.
3. Cardboard Centrifuge Tube Storage Box
This is the simplest option-used mainly when long-term freezing is not involved.
Typical use is shipping, temporary organization, or short experiments.
Available SKUs
| SKU | Tube Size | Wells | Material |
| 11321010 | 15 mL tubes | 49 | Cardboard |
| 11321011 | 50 mL tubes | 16 | Cardboard |
Key Features
- Lightweight and easy to handle
- Printed indexing helps with quick identification
- Can be stacked, but only under room temperature conditions
- Collapsible when not in use
- Not designed for -80°C or autoclave cycles
Material Comparison
| Feature | PP Box | Cardboard Box |
| -80°C freezer use | Yes, stable over time | Not recommended |
| Autoclave use | Yes (limited cycles) | No |
| Moisture resistance | High | Low |
| Structural stability over time | Very stable | Degrades in cold/humidity |
| Reusability | High | Limited |
| Cost | Medium | Low |
Application Scenarios
Molecular Biology / PCR Labs
Used for routine tube storage, primer organization, and pre-PCR setup areas where contamination control matters.
Biobanking & Cryogenic Storage
Works well for -80°C sample archiving (serum, plasma, DNA extracts). Dual-format boxes are often used here to reduce freezer clutter.
Pharmaceutical R&D
Common for compound libraries and mixed workflow environments where multiple tube sizes are used in parallel.
Clinical Diagnostics
Useful for patient sample tracking and short-term storage before analysis or transport.
Academic Labs
Main advantage here is consistency-helps reduce chaos in shared teaching or multi-user environments.

FAQ
Q: What’s the actual difference between Single-Format and Dual-Compatibility?
A: Single-Format is meant for one tube size only. Dual-Compatibility is used when both 0.5 mL and 1.5 mL tubes appear in the same workflow.
Q: Can PP boxes really go into autoclaves?
A: Yes. Most labs run them at 121°C for 20 minutes. Over many cycles, you might notice hinge fatigue, but they generally hold up well within normal usage.
Q: Why not use cardboard in -80°C freezers?
A: In practice, cardboard absorbs moisture over time in low temperatures and starts losing structure. It usually becomes a reliability issue before users notice it.
Q: Do dual-purpose boxes actually hold both tube sizes well?
A: Yes. The wells are designed to center smaller tubes while still supporting larger ones without adapters.
Q: Are these stackable in real freezer conditions?
A: Yes. PP boxes are designed for stable stacking even in -80°C environments. Cardboard is fine only at room temperature.
