Product description

High-capacity autosampler for LC with 96-sample capacity, precise injections, and automated run control.

The Varian AS-400 is an economical, high-capacity autosampler designed to automate routine liquid chromatography (LC) procedures, enhancing efficiency and precision in laboratory workflows. With a 96-sample capacity, this autosampler is particularly effective for high-throughput high-performance liquid chromatography (HPLC) quality control processes.

Key features include:

  • Unique finger valves that minimise sample volume requirements for precise loop-fill injections.
  • Single keystroke operation to initiate automated runs, simplifying routine tasks.
  • Automatic calculation of total and remaining run times, improving laboratory efficiency.
  • Four removable racks allowing sample preparation during active runs.
  • Electrically actuated Valco valve for easy access and quick servicing.
  • Separate wash vials to ensure minimal carryover and optimal results.
  • Optional 5 mL vials for larger sample volume injections.
  • Optional cooling accessory for temperature-sensitive applications.

This autosampler is widely utilised in pharmaceutical, basic chemical, and environmental laboratories, where automated, routine LC analyses are essential. Its robust design and user-friendly interface make it a valuable asset in university labs, biomedical research centres, and clinical environments. Introduced in the late 20th century, the Varian AS-400 has been a reliable tool in analytical laboratories, though it is now considered a historical model and may no longer be in active use.

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.
