VWR International 611-8240 1 g F1 calibration weight in stainless steel for laboratory balance calibration and analytical weighing.
The VWR International 611-8240 calibration weight is a laboratory mass standard for balance calibration and analytical weighing. Calibration weights also support balance calibration in life sciences laboratories.
This unit is a 1 g stainless steel calibration weight with F1 tolerance class.
The used weight was checked on a calibrated analytical balance. It is not currently calibrated in accordance with NEN ISO 17025. Some weights in the available group have expired certificates.
This calibration weight is intended for balance calibration and analytical weighing. It supports reference checks in life sciences laboratories, including sample preparation and routine laboratory measurement workflows.
The weight is used and was checked on a calibrated analytical balance. It is not currently calibrated in accordance with NEN ISO 17025. Some weights have expired certificates.
The F1 tolerance class supports the stated suitability of this calibration weight for laboratory applications. The 1 g nominal mass provides a defined reference for checking analytical balance readings.
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.
