Reciprocating Shaker for Kahn Tubes and Laboratory Sample Mixing
A reciprocating shaker is built differently from an orbital unit, it moves side to side in a straight line instead of a circular path, which is exactly what a kahn tube setup needs for even mixing without splashing. That's why this reciprocal shaker is still the standard choice wherever blood samples, culture media or reagents need steady, repeatable agitation. As a reciprocating shaker manufacturer in India, Yatherm Scientific builds each unit to run day after day without breaking down, so labs don't lose testing time to equipment issues.
This laboratory reciprocating shaker is also called a kahn shaker in many labs, named after the kahn test tube racks it was originally designed to hold. Whether your lab calls it a khan shaker, a reciprocating shaker for laboratory use, or simply a sample shaker, the working principle stays the same: a DC motor drives a back-and-forth motion that keeps every kahn tube mixing evenly across the platform.
Frequently Asked Questions About the Reciprocating Shaker (Kahn Shaker)
1. What is a reciprocator?
A reciprocator, or reciprocating shaker, is a lab shaker that moves the platform back and forth in a straight line, rather than in a circular orbit, to mix samples in tubes, flasks or beakers.
2. What is a kahn tube used for in laboratory work?
A kahn tube is a small round-bottom tube used mainly in serology and blood testing labs, and it is held on a reciprocating shaker's kahn racks while the sample mixes.
3. What is the difference between a reciprocating shaker and a rotary shaker machine?
A reciprocating shaker moves in a straight back-and-forth motion, while a rotary shaker machine moves the platform in a circular orbit. Kahn tubes and certain blood or serology tests are better suited to reciprocating motion.
4. What speed range does Yatherm's reciprocating shaker offer?
Our reciprocating shakers run from 10 to 250 rpm with variable speed control, adjustable through a manual knob with digital RPM display.
5. Can this reciprocating shaker hold different platform sizes?

6. Where are reciprocating shakers used in a lab?
Reciprocating shakers are used in pharmaceutical, hospital, college and research laboratories, and are also used alongside equipment like fume hoods, CO2 incubators, glove boxes and biosafety cabinets.
