High-precision 20g stainless steel weight, class E2 for laboratory calibration.
The VWR 20g calibration weight, classified as E2, is crafted from high-quality stainless steel, ensuring precision and durability for laboratory settings. With a maximum permissible error of ± 0.08 mg, this weight is ideal for precise measurements. It has been checked on a precision balance with a sensitivity of 0.0001g (0.1mg), as evidenced by the accompanying photograph. The weight is housed in a protective plastic box and currently remains uncalibrated.
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.
