Product description

Vacuum controller V-850 with precise pressure control 1400–0 hPa for rotary evaporators, suitable for biotech and molecular diagnostics.

The BUCHI V-850 Vacuum Controller is a precision vacuum regulation device designed for synchronization with BUCHI rotary evaporators (models R-500, 205, 210, and 215). It supports automated initiation and cessation of rotary flask rotation and automatic lifting of the jack during distillation start and stop phases, enhancing workflow in bioprocessing and molecular diagnostics. Key features include:

  • Vacuum control range: Measurement capability from 1400 to 0 hPa, adjustable from 1100 to 1 hPa with 1 hPa resolution, enabling stable vacuum conditions necessary for sensitive evaporation tasks.
  • Timed distillation control: Programmable distillation duration supports consistent process reproducibility essential in synthetic biology and biochemical research.
  • Error display: User interface with error codes on the display to facilitate troubleshooting and maintain experiment integrity.
  • Compact, lightweight design: Dimensions of 160 × 120 × 105 mm with a weight of only 0.7 kg, facilitating easy integration into existing rotary evaporation setups.

This controller is critical for molecular biology researchers and biotechnologists requiring precise vacuum regulation for live-cell imaging preparation, gene editing workflows, and other biomanufacturing applications. Note that this unit is a used device sold "as is," and original performance may vary. Confirm compatibility with rotary evaporators prior to purchase.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
