Product description

Cryostat with temperature down to –35 °C, section thickness 1–60 μm, for histology and clinical pathology.

Leica CM1850 Cryostat

The Leica CM1850 is a precision cryostat designed for rapid freezing and sectioning of tissue samples, essential in histology and clinical pathology laboratories. This instrument ensures high-quality frozen sections, facilitating accurate and timely diagnoses.

Key features include:

  • Temperature Control: Maintains chamber temperatures down to –35 °C, with an actively cooled quick-freeze shelf reaching –60 °C, ensuring optimal sample preservation.
  • Efficient Sectioning: Offers section thickness settings from 1 to 60 μm, accommodating diverse research needs.
  • User-Friendly Design: Features an ergonomic knife holder, intuitive control panel, and a spacious cryochamber with a heated sliding window for enhanced operator comfort.
  • Safety Measures: Equipped with a splash-protected microtome and safety handwheel, prioritising user safety during operation.
  • Energy Efficiency: Incorporates advanced insulation technology, leading to approximately 10% power savings compared to conventional systems, enhancing durability and performance.

The Leica CM1850 is widely utilised in biotechnology, molecular biology, and clinical diagnostics for applications such as:

  • Rapid Disease Diagnosis: Enables quick assessment of tissue samples, crucial in clinical settings.
  • Enzyme Histochemistry Studies: Facilitates the study of enzyme activity within tissues.
  • Molecular Analysis: Preserves RNA or DNA in tissues for subsequent molecular investigations.

Commonly found in university laboratories, biomedical research centres, and clinical environments, the Leica CM1850 has been a trusted tool in the scientific community. Although discontinued and replaced by the Leica CM1860, the CM1850 remains in use in various institutions, reflecting its enduring reliability and performance.

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.
