Enhanced absorbency: More absorbent than Grade 1, facilitating better retention of particulates.
Low ash content: ≤0.06%, ensuring minimal interference in analytical procedures.
Consistent thickness: Approximately 190 μm, providing uniform performance across samples.

Applications:

Environmental monitoring: Used for detecting specific contaminants in air and soil samples.
Agricultural research: Holds soil nutrients in plant growth trials, aiding in soil analysis and seed testing.
Biotechnology: Employed in various bioprocessing workflows, including cell culture and protein purification.

Commonly used in:

University laboratories: For teaching and research purposes across multiple disciplines.
Environmental agencies: Monitoring and analysing environmental samples.
Biotechnology firms: Integral in biomanufacturing and molecular diagnostics processes.

Introduced by Whatman plc, a company with a legacy dating back to 1740, the No.2 filter paper has been a staple in laboratories for decades and continues to be widely used in contemporary research and industrial 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.
