"We've been quite impressed with the build quality and design of everything. The suitcase works great. I'm used to living in fear of dropping samples in UHV but the design of the suitcase, manipulators and sample storage make moving samples around fairly low stress. We are very satisfied customers."

J. Brandon McClimon, Carpick Lab, University of Pennsylvania

"Your hardware works very well, the wobblestick is exceptional, and even more importantly, you have given us good customer care."

M. Valvidares, ALBA Synchrotron, Barcelona

"My group purchases a lot of items from Ferrovac, and very much like the excellent quality of your products."

"Thank you again! We are big fans of your products."

Kyle Shen, Cornell University

"I would like to let you know that we installed the WMG40-0215-0182-PGWMSN(OM)-TSWM on our chamber a few weeks ago. We truly appreciate the support from you and the Ferrovac engineers in this order."

H. Tsai, University of California, Berkeley

"I am delightfully starting construction of two low temperature near-field microscopes.
We have learned a lot from past years about what works and what doesn’t in these systems, but the Ferrovac ingredient is part of the magic that makes the whole business work."

Prof. Alexander McLeod
mcLeod nono-Optics and  Photonics (mnOP) Lab
University of Minnesota Twin Cities

"We ordered a custom-based ambient pressure XPS endstation from Ferrovac to study solid-liquid interfaces. Ferrovac did an excellent job both in terms of engineering and assembly and delivered the product on time. This endstation is very productive from the very first day it was connected to the synchrotron at the Swiss Light Source."

Z. Novotny, Scientist, Paul Scherrer Institute/University of Zuerich, see more: SLAPXPS

"Last time we ordered from Ferrovac, we were positively impressed with the quality of your products. I do believe your products are among the best on the market."

Alexei Preobrajenski, Lund University, MAX IV Laboratory

We are proud to support scientists throughout the world in their perpetual struggle towards and beyond the borders of todays knowledge.

The Ferrovac Magnetically Coupled Wobble Stick Manipulator - The Original

Magnetic coupling as the driving principle for wobble sticks was introduced by Urs Maier in the early 1990's.  Since then, Ferrovac magnetically driven wobble stick manipulators define the benchmark for delicate and precise manipulations in ultra high vacuum systems.

Due to the principle of magnetic force coupling, the motion of the shaft is not affected by the difference between atmospheric pressure and ultra high vacuum. The operator can guide the shaft of the wobblestick nearly force-free in a smooth and controlled way.

Magnetic coupling also minimizes the risk for leaks and ensure longer lifetimes compared to conventional wobble sticks employed with long bellows stacks for linear motion.

Magnetically driven wobblestick manipulators always allow for continuous rotation of the shaft.


Beware of cheap copies!

In recent years, the proven Ferrovac design has been copied by many of our competitors. While admittedly some of our competitor's wobble sticks are well made, others may not fulfill your expectations in terms of degassing, long lifetime and smoothness of motion. Note: We are servicing and refurbishing Ferrovac wobblesticks dating back to the years when we first introduced the design!

Off the shelf wobble sticks are in stock and available with lead times of a few days!


Motion & Manipulation

All our motion feedthroughs are magnetically driven. They are rugged, precise and have low outgassing rates upon movement. Our products are ideal for UHV applications down to the very low E-11 hPa (mbar) range.

Luxembourg Institute of Science and Technology (LIST)

Ferrovac Ultra High Vacuum Technology's combined load lock and docking station for our brand new inert gas shuttle was successfully installed at Luxembourg Institute of Science and Technology (LIST) by Claudio Weiss.

Congratulations Claudio and both, our engineering and production teams!

FerroLoaderTM Docking Kits for Helios

for more information,
see product catalog page

FerroLoader™ Docking Kit for Thermo Fisher Helios DualBeam FIB-SEM

Another good example of Ferrovac's excellent collaboration with Thermo Fisher Scientific!

This FerroLoader™ was recently installed to a Helios™ in Brno.

The video nicely shows how Thermo's new Inert Gas Shuttle (IGS) interfaces with the Ferrovac docking station.

With a few simple moves, the IGS can be exchanged with the Ultra High Vacuum Transfer Module (UHVCTM).

Equipped with a liquid nitrogen dewar for active sample cooling, thermal shields (CTD50SHIELDS) enshrouding the sample, as well as a temperature measuring kit, the Ultra High Vacuum Cryo Transfer Module (UHVCTM) enables transport of sensitive samples at cryogenic temperatures under true UHV conditions (E-11mbar).

The UHVCTM is, especially compact, lightweight, robust and easy to use.

Cryo Sample Receiver and Carrier with 13 electrical Contacts, arbitrary orientation

Wire up your devices on flag style plates!

Typical applications include low temperature scanning probe microscopy, transport measurements or simply the mounting of a temperature sensor directly to the sample. 


This particulair version of the EC13 sample receiver is optimized for cryogenic applications and can be loaded/unloaded in any kind of geometrical orientation (i.e. vertical, upside-down..).

The receiver is equipped with a lever mechanism, pressing the sample plate down onto the cold  surface. Locking is engaged by approximately a quarter turn using the pincer on the wobblestick used to handle the sample. By tightening the screw, the lever presses onto both sides of the sample plate, forcing it down.

An improved  thermal contact to the cooling surface is achieved and the temperature difference between the sample and the receiver is only about 2 Kelvin.

Loading/unloading of the sample and operation of the locking screw requires a WMG40 dual shaft wobblestick with PGWMS(OM) pincer.


Up to 13 electrical high-quality spring contacts for wiring up devices

The SHOMEC13 features a total of thirteen high-quality spring contacts mounted into an AlN-isolator. The shape and opening of the top plate and shield cover can be customised to your needs. A pocket underneath the sample mounting plate allows convenient installation of a temperature sensor

PBN Heater Assembly with Receiver for Flag Style Plates


A 50W pyrolitic boron nitride heater in combination with a molybdenum receiver for flag style plates provides a reliable solution for sample annealing. A K-type thermocouple is mounted on the sample receiver.

HSOMPBN50 heaters can be implemented in fully configured heating stages including flange assembly with electrical feedthroughs. The HSOMPBN50 is also used in BOOMERAX manipulators and can be easily adapted to practically any commercially available XYZ manipulator.

Receiver for Flag Style Sample Plates with integrated PBN Heater

  • Power: 100W (24V, 4.2A ~1000°C)
  • Maximum temperature approx. 1000°C
  • Thermocouple: Type K (chromel/alumel)
  • Fully UHV compatible materials
  • Power supply not included
