Product description

Explosion proof manual defrost refrigerators (DHH4 series) for safe biochemical and clinical sample storage.

The So-Low DHH4 series encompasses explosion proof manual defrost laboratory refrigerators specifically designed for critical storage needs in biochemical, molecular diagnostics, and biopharmaceutical research environments. Models DHH4-17SDRX, DHH4-20SDRX, and DHH4-30SDRX offer robust safety features compliant with hazardous location standards, ensuring secure containment of flammable reagents and sensitive samples.

Key technical features include:

  • Explosion proof certification, enabling use in volatile chemical laboratories and clinical diagnostics facilities where combustible gases or vapors may be present
  • Manual defrost system minimizing vibration and temperature fluctuation, crucial for consistent biochemical storage conditions
  • Storage capacity tailored to sample sizes across molecular biology, synthetic biology, and bioprocessing workflows
  • Durable construction engineered for reliable cold storage in biotechnology labs focusing on biomanufacturing and gene editing research
  • Precise temperature control ideal for the preservation of reagents, media, and clinical specimens involved in molecular cloning workflows and biomedical engineering applications

These refrigerators are widely adopted in synthetic biology research and critical in biopharmaceutical production pipelines for maintaining sample integrity under explosion-proof safety protocols. The DHH4 series supports essential workflows including fluorescence analysis and live-cell imaging preparation, making them a secure and reliable component for advanced laboratory cold storage infrastructure.

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.
