Selection Guide
Use the table below to select the right BUCHI vacuum pump for your application:
- Ultimate vacuum required < 2 mbar + solvent resistance: → V-700 (0800011508) ✓ Recommended
- Ultimate vacuum required < 1.5 mbar: → V-710 (0800011509)
- Budget-sensitive, non-critical evaporation: → V-600 or cross-brand equivalent
- High-throughput parallel evaporation: → BUCHI Multivapor with dedicated pump manifold
- Corrosive gas handling (HCl, HBr): → Vacuubrand MZ 2C NT with PTFE head (consult Konmask)
Key selection parameters: ultimate vacuum (mbar) · pumping speed (L/min) · chemical compatibility · voltage · noise level · OEM system interface.

Replacement & Compatibility FAQ
Q: Is the BUCHI V-710 a direct replacement for the V-700?
A: Yes, in most cases. The V-710 offers a slightly lower ultimate vacuum (1.5 vs 2 mbar) and is backward-compatible with all R-series rotary evaporators that support the V-700.
Q: Can I use a Vacuubrand MZ 2C NT instead of the V-700?
A: Functionally comparable. You will need a hose adapter (8 mm to 10 mm) and the vacuum controller interface may require manual calibration.
Q: What do part numbers 1127-452-02, 27220C, and BTS10-2,5/8-24-RL-720 refer to?
A: These are alternate BUCHI internal reference codes and OEM sub-assembly identifiers for the same V-700 pump unit. All refer to part 0800011508.
Q: Is this pump suitable for use with chlorinated solvents (DCM, chloroform)?
A: Yes. The full PTFE/PVDF fluid path provides excellent resistance to halogenated solvents. Ensure adequate ventilation and use a cold trap upstream.
Q: Do you offer volume discounts for laboratory procurement?
A: Yes. Contact support@konmask.com with your required quantity for a B2B quotation.
