ASTM E-11 compliant 12" test sieve with 53μm aperture for precise particle size analysis in biotech and industrial labs.
The Tyler #270 Brass 12-Inch Test Sieve features a *53μm (0.0021") aperture* stainless steel cloth mounted in a durable stainless steel frame, designed for high-precision particle size analysis. Manufactured to meet stringent ASTM E-11 specifications, this test sieve ensures permissible variation in average openings is within 50% of ASTM or ISO standards. Ideal for applications across *biotechnology, pharmaceuticals, bioprocessing, molecular diagnostics*, and *materials science*, it supports accurate particle measurement vital in *biomedical engineering, synthetic biology research,* and *biomanufacturing quality control*.
Key Technical Features:
This sieve is essential laboratory equipment for scientists and researchers focused on *particle characterization*, *fluorescence analysis sample preparation*, and *bioprocessing material evaluation*. Its robust construction and certification make it a trusted choice in *clinical diagnostics* and *synthetic biology labs* requiring standardized particle size separation and biomaterial filtration.
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.
