Product description

Binary HPLC pump delivering pulse-free flow up to 10 mL/min; includes degasser, seal wash, and column heater.

The Waters 1525 Binary HPLC Pump is a high-pressure, binary high-performance liquid chromatography (HPLC) pump designed to deliver precise, pulse-free solvent flow for both analytical and semi-preparative applications. Its robust design ensures reliable performance, making it ideal for use with highly sensitive detectors in various laboratory settings.

Key features:

Programmable flow rates: Adjustable from 0.00 to 10.00 mL/min in 0.01 mL increments, accommodating diverse analytical needs.
Extended Flow (EF) heads: Optional feature allowing flow rates up to 22.50 mL/min, suitable for 10 to 19 mm I.D. columns.
Integral vacuum degasser: Removes dissolved gases from the mobile phase, enhancing performance and reliability.
Automated seal wash: Extends the primary seal life, ensuring consistent operation.
1500 Series Column Heater: Maintains column temperature between 20 to 60 °C for accurate and consistent results.
FlexInject manual dual injector module: Facilitates both analytical and semi-preparative injections.

This pump is widely utilised in biotechnology, pharmaceutical research, and clinical diagnostics for applications such as bioprocessing, gene editing, and molecular diagnostics. Its precision and reliability make it a valuable asset in university laboratories, biomedical research centres, and biopharmaceutical production facilities.

Introduced in the early 2000s, the Waters 1525 remains relevant in laboratories today, offering dependable performance for a range of chromatographic 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.
