Product description

Used stainless steel calibration weights for laboratory balance calibration, mainly with F1 and E2 tolerance classes.

Used laboratory calibration weights support balance calibration in biotechnology and life sciences laboratories. The weights are available in stainless steel, with mainly F1 and E2 tolerance classes.

Examples include calibration weights from Sartorius and Troemner. The F1 and E2 classifications define the tolerance class of the weights.

The weights are used and were checked on a calibrated analytical balance. Some weights have expired certificates. They are not currently calibrated in accordance with NEN ISO 17025, and the new owner can arrange calibration when required.

Used calibration weights for laboratory balance calibration and verification.

  • Stainless steel construction
  • Mainly F1 and E2 tolerance classes
  • Sartorius and Troemner weights included among the available examples
  • Weight checks performed on a calibrated analytical balance
  • Some certificates have expired
  • Current calibration in accordance with NEN ISO 17025 is not provided
  • Calibration can be arranged by the new owner when required

What these specifications mean

F1 and E2 tolerance classes are suitable for laboratory applications and distinguish the accuracy classification of the available calibration weights.

The weights are not currently calibrated in accordance with NEN ISO 17025. Some certificates have expired, so current calibration documentation is not uniform across the available weights.

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.
