Product description

Compact ULVAC DTC-21 dry diaphragm vacuum pump with PTFE wetted parts, chemical resistant, 24 L/min flow, ideal for organic solvents.

The ULVAC DTC-21 is a dry diaphragm vacuum pump engineered with PTFE wetted parts for exceptional chemical resistance and corrosion durability. Its design is optimized for handling organic solvents and corrosive gases, making it highly suitable for applications in chemical laboratories, biotechnology workflows, and molecular diagnostics requiring reliable vacuum generation with resistant materials.

Key technical features include:

  • Exhaust speed of up to 24 L/min at 60 Hz, supporting continuous and stable vacuum output.
  • Ultimate pressure capability reaching 1.0×10⁻³ Pa, enabling high vacuum conditions essential for sensitive bioprocessing and analytical equipment.
  • Compact footprint with dimensions of 114×288.5×202 mm (standard) and reduced size for embedded installations (114×242×184 mm), fitting limited laboratory space.
  • Low noise and vibration operation, alongside reduced power consumption, enhance its utility in noise-sensitive environments such as biomedical engineering labs.
  • The PTFE gas contact surfaces offer outstanding resistance to aggressive chemical vapors, extending pump lifetime and simplifying maintenance in demanding research settings including synthetic biology and biomanufacturing.
  • RoHS compliant design ensures suitability for regulated laboratory environments.

This unit's compact size, combined with its chemical resistance and dry operation, makes it ideal for live-cell imaging setups, fluorescence analysis instruments, and other biotechnological instruments where contamination-free vacuum is critical.

Note: This listing is for a used pump sold as-is, with no guarantee of original new condition or functional performance. It remains a valuable asset for labs requiring economical, durable vacuum solutions suitable for a wide range of biomedical and chemical research applications.

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.
