Mettler Toledo calibration weights for laboratory weighing, stainless steel, F1 and E2 tolerance classes, used and checked on an analytical balance.
The Mettler Toledo calibration weights are laboratory reference weights used for weighing in life sciences laboratories and other laboratory applications.
The weights are made of stainless steel and are available in F1 and E2 tolerance classes. These classes distinguish the supplied laboratory weight configurations.
The weights are used. Their weight was checked on a calibrated analytical balance. Some weights have expired certificates. They are not currently calibrated in accordance with NEN ISO 17025.
Mettler Toledo calibration weights for laboratory weighing and balance verification.
The F1 and E2 tolerance classes identify the available weight grades. The required class must match the calibration procedure for the analytical balance or weighing application.
An expired certificate does not establish current calibration status. The weights are not currently calibrated in accordance with NEN ISO 17025.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
