Minus K Congratulates to the following winners of Minus K's 2023/2024 Educational Giveaway
With over thirty years in business, Minus K Technology has to-date granted over $85,000 of its superior performing patented Negative-Stiffness low-frequency sub-hertz vibration isolators through their U.S. Educational Giveaway. This year Minus K congratulates the following winners for the 2023/2024 giveaway: Wabash College - Physics Department The vibration isolator will be used with their Zeiss 508 Microscope to conduct experiments utilizing high magnification to image Brownian motion in time-lapse imaging of chemical precipitation material formation. Kent University - Physics Department The vibration isolator will be used for a magnetic tweezer instrument to be built on it. Fast video imaging (several hundred images per second) is used to measure the changes in the depth of glass beads (of a few micrometer diameter). Texas Christian University – Physics & Astronomy Department The vibration isolator to be used with their 6-digit RADWAG XA 21.4Y.M microscale to improve precision of small mass measurements down to 1 microgram. Indiana University – Physics Department The vibration isolator will be used to for dynamic micro-optical coherence tomography of the heterogeneous intracellular motion present in living cells and tissues. “We are happy to help universities get the tools to advance their research.”, says Minus K’s President Steve Varma, “It is a great feeling to help all these colleges with their research as we celebrate our eighth year of granting our vibration isolators to U.S. colleges and universities. We are always interested in seeing what applications and how the isolators will be used.”

New CT-10 Ultra-Thin, Compact Low-Height, Low-Frequency Vibration Isolation Platform Adapts to Space Constraints in Critical Micro- and Nano-Microscopy
At about 2-1/2 inches in height, while isolating vibrations as low as 1 hertz, the new completely-passive Negative-Stiffness tabletop vibration isolation platform – developed by Minus K Technology – provides the industry’s thinnest low-height, low-frequency isolator for Microscopy (SPM, SEM, AFM, etc.), Micro-Hardness and Nano-Indenter Testing, Laser/Optical Systems, Biology/Neuroscience Systems, Spacecraft Ground Testing, Analytical Balances, Audio Reproduction, Vacuum and Cleanroom applications. The new ultra-thin, low-height model CT-10 passive isolator – the more compact than the CT-2 to fit in much smaller spaces at just over 12 ½ inches square. The completely passive tabletop unit is 2.7 inches in height, yet delivers 1/2 Hz vertical natural frequency, and ~1-1/2 Hz horizontal natural frequencies – considerably more low-frequency vibration isolation performance compared to air tables and active systems. The CT-10 utilizes Minus K's breakthrough patented technology that led to a Laser Focus World 2019 Innovation Award. “Vibration isolators for small microscopes, especially AFM, have typically been much larger than needed. We have heard from users looking for an even more compact isolator that what we previously had. People just like small isolators. They want the performance our isolators offer, in as small a package as possible,” said Erik Runge, V.P. of Engineering. “With the CT-10, we offer the most compact 0.5 Hz isolator we have ever produced.” Negative-Stiffness isolators employ a unique and completely mechanical concept in low-frequency vibration isolation. They do not require electricity or compressed air. There are no motors, pumps or chambers, and no maintenance because there is nothing to wear out. They operate purely in a passive mechanical mode. The Negative-Stiffness CT-10 isolator achieves a high level of isolation in multiple directions. It has the flexibility of custom tailoring resonant frequencies vertically. The transmissibility of the CT-10 is substantially improved over air and active isolation systems. When adjusted to 1/2 Hz vertical natural frequency, the CT-10 Negative-Stiffness isolator achieves approximately 93 percent isolation efficiency at 2 Hz; 99 percent at 5 Hz; and 99.7 percent at 10 Hz. “With new emerging technologies, vibration isolation is becoming even more important. Not all these technologies need, or even want, to use larger sized isolators,” added Runge. “The CT-10, with its patented technology, offers the signature 0.5 Hz vertical performance we have become known for, in a much smaller package. The CT-10 isolates low-frequency vibrations (vertically) as well as our largest isolators.” Negative-Stiffness vibration isolation systems have become a growing choice for micro and nanotechnology microscopy applications. Not only are they a highly workable vibration solution, but they provide location flexibility and portability that other vibration isolation systems cannot.
