Calibration weight set (5g to 500g) by Murakami Seiki for precision balance calibration with certification.
This Murakami Seiki Manufacturing 5410 calibration weight set includes grades from 5g to 500g, designed for precise calibration of laboratory balances and analytical scales. The set consists of five individual weights: 5g, 20g, 50g, 200g, and 500g, suitable for a broad range of mass calibration requirements in biotechnology, molecular diagnostics, and bioprocessing labs. Supplied with an official calibration certificate, these mass standards ensure traceability and accuracy for critical weighing operations. As a used set sold as-is, the weights may not retain the original factory specifications, and verification of performance prior to use is recommended. This set is essential for routine quality control and equipment compliance in laboratory environments requiring accurate mass measurements.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
