“Our company prefers the Minus K vibration isolation platform for use with our SPM/NSOM system. This platform reduces the noise to well below 0.1 nm which is unachievable with any conventional optical table. The Minus K platform is particularly effective in cutting low-frequency vibrations. Reducing the noise by over an order of magnitude has helped us obtain optimal SPM performance integrated with a variety of optical and electron optical tools. This has led to new horizons in scanned probe and integrated microscopy.”

“We have tested a Nano-K bench top platform for several
months; it has outperformed our air table in all specs. I
am very much impressed by its performance. As a designer in
the AFM field for over 15 years, I truly appreciate the ingenious
design of this bench top platform. It is simple and elegant.
It is the best for the buck for isolating an AFM system from
the floor vibrations.

“Vibration isolation is an absolute must for Atomic Force Microscopy. The Nano-K isolators provide the best performance, affordability and convenience available. They have enabled us to get data in environments that would have been prohibitive otherwise. Everyone involved in AFM should be using Nano-K isolators.”

“We have found the last several years of working with Minus K and your products very satisfying. Your tables are honestly a great invention that actually live up to their specs. With the Minus K we have been able to consistently collect precision data that just wasn't possible with our old air tables. Thanks for an awesome product.”

“We originally selected the Minus K vibration isolation tables as a solution for challenging installations of our nanomechanical test instruments, with the intention of sticking with air tables as a lower cost, standard product. Within a short period of time, we re-evaluated that decision and began using Minus K tables on all of our Nano Indenter products. The performance is exceptional ¯ since switching to Minus K, field installation problems associated with vibration have been virtually eliminated. But equally impressive are the quality of the product, innovation in design, and outstanding support. Minus K has been a great OEM partner!”

“We've used the Nano-K table and found its performance to be significantly better than traditional air tables. With the Nano-K, nanoindentation experiments on our NanoTest system are now possible at very low depths (under 10 nm) without worrying about the external environment.”

“We have used the Biscuit tables from Minus K and found them to be far superior to tables we have previously tried. We are especially impressed with the isolation performance in the X-Y plane. Using these tables resulted in a ten fold reduction in vibrational noise which greatly facilitated measurements of absorption and fluorescence from neurobiological preparations.”

“My laboratory studies the brain activity using voltage-sensitive dye imaging methods. Before the introduction of the Minus K tables we used high quality air tables. These tables were not adequate for isolating low frequency vibrations so we had to put a second air table on top of the first one.
In 1995 we bought the first Minus K table. We were impressed by its superb performance, at least ten times better than the air tables we were using. We told this news to other scientists and since then at least 20 laboratories have bought Minus K tables. We have four of them in our laboratory. We all suffer much less headaches from floor vibrations.”

“It is my great pleasure to provide this testimonial for Minus K Technoloty vibration isolation systems. As a neuroscientist depending extensively on electrophysiological and imaging techniques, I am keenly aware of the fundamental importance of properly isolating these rigs from building vibrations. I have for many years relied on passive pneumatic vibration isolation tables for this purpose. Recently, when moving labs, I was confronted with a situation in which my existing vibration isolation equipment was inadequate. Analysis of the building and floor vibration characteristics revealed large amplitude vibrations at frequencies below 5 Hz at this new location. Field tests with an in vitro patch clamp rig, using a standard pneumatic vibration isolation table were unsatisfactory. Attracted by their performance claims (i.e., natural frequencies of 1/2 Hz or better) and competitive pricing I decided to test a Minus K vibration isolation unit with the same in vitro electrophysiology rig, despite my initial skepticism concerning the manufacturer’s performance claims. The Minus K unit performed magnificently, surpassing my best expectations. We performed a number of tests. Perhaps the most vivid way to illustrate the results of these tests is to say that a gang of colleagues literally jumping around at no more than 8 ft distance did not cause any disturbance in an active patch clamp recording. Based on these results, I am equipping my lab with Minus K vibration isolation units. Summarizing, Minus K solved my vibration problem in a very cost-effective manner and I encourage my colleagues dealing with similar problems to test these systems for themselves.”

“I just wanted to commend Minus K on building an outstanding product – we are extremely pleased with our BM-1 bench top isolator.
Minus K’s negative stiffness technology intrinsically makes sense to me as a mechanical engineer, and brings truly fresh thinking to the problems of vibration isolation. Moreover, negative stiffness works – and not only does it work, but it works better than many other solutions. After we evaluated numerous audiophile and industrial vibration isolation solutions, we found that Minus K was not only one of the strongest performers for our high-end audio application, but also provided excellent value.
Before learning of Minus K, we had anticipated needing either an air based or active isolation solution to get the sonic performance we wanted, and were pleasantly surprised to find that we could achieve the same performance using a passive solution from Minus K while simultaneously eliminating the need and extra cost for special facilities like air or power. In addition, installation and set-up couldn’t have been quicker or easier – we unpacked our isolator and had our application set up in about 20 minutes without any difficulties.
You can count The Audio Archive as a satisfied customer, and we will certainly look to Minus K again to meet our future needs.”

"A Minus-k vibration isolation system should be considered
mandatory by anyone who is serious about vinyl playback. With
its 0.5-Hz natural frequency, the isolation performance of
the BM-8 system is vastly superior to most of the “audiophile”
products on the market. This upgrade to
my analog source has allowed me to hear everything that is
on the LP by thoroughly isolating the playback system from
ambient vibrations. We have done the “jump-up-and-down”
test many times: even heavy falling objects near the turntable
have absolutely no audible effect. I live in an 80-year-old
house built on a pier-and-beam foundation, about the furthest
thing from a well-damped oscillator. My listening room
therefore would be an extreme challenge for any vibration-isolation
It is difficult to overstate the benefits of this level of isolation to analog music reproduction. Images are palpable and more stable, there’s an enormous reduction in the “noise floor,” and it’s now possible to appreciate the full scale and dynamic range of an LP recording. The folks at Minus-k are extremely accessible and go out of their way to make certain that their products work in your particular application. In my case, I needed a modification so I could independently level the isolator. They custom-engineered a solution for me and shipped it within days.
I first became aware of their products as an atomic-force microscope user, but decided to ignore the usual “do not try this at home” caution. I am extremely glad that I did and am considering another Minus-k system – this time for laboratory use."
