Hand-Operated Centrifuge Machine, Table-Mounted, 4-Bucket 15 mL, No Power Required
Couldn't load pickup availability
Manual hand-crank blood centrifuge for field labs, blood banks, veterinary practices, and rural clinics with no reliable power. Table-mounted design with integral clamp, bolts securely to any lab bench. Swing-out 4-bucket head with polyamide buckets for 15 mL glass or plastic tubes. Metal body encloses steel pinion and worm-drive gearing with high-quality ball bearing assembly. Removable crank handle. Single-speed 1500-2000 RPM (~500-800 g force at bucket radius), sufficient for serum/plasma separation, blood chemistry prep, hematocrit reads, and general clinical spin-downs. No electricity required. $99.99 (Plastic Body) / $249.99 (Metal Body). NOTE: Vacutainer tubes NOT included.
Variant Selection
| Variant | Body / Durability | Best For | Price |
|---|---|---|---|
| Metal Body | All-metal construction, highest durability, stable at high crank speeds, longer service life in field use | Field clinics, veterinary practices, long-term deployment, humanitarian/NGO kits | $249.99 |
| Plastic Body | Steel gearing inside polymer housing, lighter, easier to transport, budget-friendly | Teaching labs, occasional field use, back-up centrifuge, quick-deploy kits | $99.99 |
Applications
- Blood serum / plasma separation: clinical chemistry prep in field labs
- Hematocrit measurement: with 15 mL Wintrobe tubes (packed cell volume reading)
- Urine sediment analysis: spin-down for microscopic examination
- Veterinary blood work: mobile vet practices, farm calls, wildlife rehab
- Humanitarian medical missions: MSF / WHO / NGO deployments in low-infrastructure areas
- Military field medic: combat support hospitals, forward operating base labs
- Rural and remote clinics: where grid power is unreliable or absent
- Disaster response: earthquake / flood / conflict zone medical care
- Teaching labs: physics of centrifugation demonstration (undergraduate lab curriculum)

Frequently Asked Questions
Can this replace an electric centrifuge?
For basic clinical spin-downs (serum separation, hematocrit, urine sediment), YES. For high-speed applications (nucleic acid pelleting, gradient purification, protein pelleting at 10,000+ RPM), NO. Hand-crank tops out around 2,000 RPM. It's a targeted tool for low-infrastructure and portable-medicine use cases.
How does this compare to Drucker / IEC / Sorvall?
Different device class. Drucker, IEC and Sorvall are electric centrifuges targeting 3,000-15,000+ RPM. This is a hand-crank field centrifuge targeting no-power / low-power environments. Use case: humanitarian medicine, rural clinics, veterinary field work, disaster response, teaching. Price differential: $99-$249 vs $1,500-$8,000 for electric bench units, different problem, different tool.
Are Vacutainer tubes included?
NO, centrifuge only. Vacutainer tubes must be sourced separately (we also stock 3.2% sodium citrate Vacutainers). 15 mL glass conical or Wintrobe tubes fit the bucket sockets.
What's the RCF (g-force)?
At 2,000 RPM with typical bucket swing radius (~8 cm), RCF ≈ 358 × g. Sufficient for serum separation (typically requires 1,000-2,000 × g × 10 min in electric, or 500-800 × g × 15-20 min manual). Adjust spin time to compensate for lower g-force.
