Questions about ULTIMATE-CELL stackable shaking incubator USOK 1257 Intuitive touchscreen panel,
What is this article?
ULTIMATE-CELL stackable shaking incubator USOK 1257 Intuitive touchscreen panel, is the article on this page. Luminix Health distributes Zefa for laboratory use. It sits in Sieve shakers, inside Test sieves & mills, in Lab instruments.
A sieve shaker repeats a throw so a particle-size test does not depend on who shook the stack. The amplitude, the timer and the frame diameter it accepts are the specification. A shaker for 200 mm frames does not hold a 300 mm stack.
A test sieve sorts particles by whether they pass an opening. Wire mesh and perforated plate are two ways of making that opening, and the nominal size is not a suggestion. A sieve shaker repeats the motion so the result does not depend on how hard someone shook by hand. A mill or grinder makes the particles smaller before they are sieved. The certificate of the sieve, and the opening size, are what an audit asks for. Measurement practice around mass and dimension sits with the BIPM, EURAMET and BELAC.
