Product description

ASTM weight sets for calibrating analytical, precision, and portable balances with Class 1, 2, and 4 accuracy levels.

ASTM weight sets provide standardized calibration solutions essential for verifying the accuracy of analytical and precision balances. These sets comply with ASTM standards and come in Class 1, Class 2, and Class 4 accuracy grades to accommodate various laboratory requirements:

  • Class 1 and Class 2 weights deliver high precision, making them ideal for calibrating analytical balances used in biotechnology, molecular diagnostics, and bioprocessing workflows.
  • Class 4 weights offer a cost-effective option with lower accuracy suitable for portable balances and bench scales commonly used in clinical diagnostics and biomedical engineering.
  • The sets include a comprehensive range of test weights enabling accurate calibration across diverse weight ranges, critical for maintaining measurement traceability in research and quality control.
  • These ASTM-certified calibration weights support reliable data integrity in applications like synthetic biology, gene editing, and biomanufacturing, where precise mass measurement is vital.

Widely adopted in laboratories for maintaining compliance and ensuring accurate mass measurements, ASTM weight sets are a foundational tool in biotechnology research and industrial bioprocessing environments.

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?

Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
