We produce the Nano Channel Chips ourselves in the world-class clean room facility of DTU in Denmark.
All Nano Channel Chips are in principle very similar, but the thickness of liquid and membranes vary, as well as the channel pattern which can be optimized for liquid-area in the field of view or specific flow and mixing capabilities.
If we do not have the chips you need in stock, we’ll make them for you!
Adjust SiN thickness down to 10 nm and liquid thickness down to 20 nm – and let us design a nano channel flow structure that suits your need for mixing, flow, or maybe just having a large viewing area.
Optional: Heating up to 150 C°
Recommended use with Fluigent pressure-based flow controller
Available for JEOL and Thermo Fisher TEMs
Possible to rent on a monthly basis!
This 4-inlet flow control holder makes the best use possible of the Nano Channel Chip, which also has four inlets. The TEM flow holder has four inlet ports in the back which can be accessed to control flow and mixing during TEM experiments.Together with a Fluigent pressure-based flow control system, you can flow and mix to the full extent possible with the Nano Channel Chip.
Optional: Heating up to 150 C°
Available for JEOL and Thermo Fisher TEMs
Extra high tilting angles possible
Possible to rent on a monthly basis!
This static holder is an extremely robust and easy-to-use TEM holder.
It is the fastest and most reliable solution in the world when it comes to getting high-resolution imaging in liquid.
Because there are no flow-tubes in this holder, it can be made much thinner and more narrow, to maximize alpha-tilting inside the TEM.
Available in PEEK, Aluminium, Stainless Steel 316
Recommended use with Fluigent pressure-based flow controller
Excellent add-on for refining TEM experiments in optical before wasting precious TEM time

Over the last several years, we have been using our SEM / optical holder a lot more than our TEM holders! The reason is that it is very easy to use and enables us to “play” with our Nano Channel Chip until we find the correct procedure for preparing the sample and flow/mix it in the right way – before wasting precious and more demanding time on the TEM. A lot of details can be observed in optical or SEM, and as long as atomic details are not required, it is an excellent way to start refining your experiment. And a lot can actually be seen in optical. In dark-field optical microscope, it is possible to see particles down to 50 nm in size. And due to changes in the refractive index, it is possible to see if something precipitates in the nano channels. We therefore recommend starting with a SEM / optical holder or getting one as an add-on to your TEM holder, to save you precious time and make optimizing experimental setups a lot easier.

Flow EZTM 2000
Fluigent’s Flow EZ system enables individual control of up to 12 flow channels in one flow system. Each module is simply connected to the previous in a series and without any further complexity. Each module is controlled individually by manually turning a knob on the controller, or by using Fluigent’s all-in-one software which also allows to pre-program a pressure program.
– Modular and plug-and-play extendable Design
– Use with or without PC
– Dial in the pressure thanks to rotary knob
– Unmatched response and settling times–
High resolution pressue sensor: 0.03% full scale
– Up to 12 modules in a row
– Including 4 mm gas outlet tubing.
Flow Rate Sensor S
By adding a flow sensor to the setup, the Flow EZ controller can self-regulate the pressure to maintain a stable flow in the channels.
– From 10 nl/min up to 7 μl/min (70 μl/min for IPA)
– Wetted material: PEEK and quartz glass
– ID 150 μm
– Dual calbration for water and hydrocarbons
– Connection for 1/32'' OD Tubing
FLUIGENT Low Pressure Generator FLPG (Silent)
Many labs have an outlet with pressurized air available somewhere in the lab. If that is not the case, Fluigent provides a stable pressure source of 2.3 bar as well.
– Delivers air for up to 8 channels at up to 2 bar
– Air tank, air dryer and manual regulator included
– Low vibration and noise level
– Clean, dry and oil-free and maintenance free air supply
– Dimensions W x H x D: 180 x 160 x 270 mm
Pfeiffer Vacuum Cube
With a HiCube pumping station from Pfeiffer it is possible to quickly and reliably leak-test the holder. The pump goes down to pressures in the range of e-7 mbar which is about the same as in the TEM. The pumping station can also be used to store one or more holders when they are not being used.
OPTICAL MICROSCOPES
We highly recommend using an optical microscope as part of the experimental procedure. In an optical microscope, it is possible to verify that the Nano Channel Chip has been filled correctly and often it is possible to identify if the sample has successfully been flown into the nano channels as well. Having an optical microscope as part of the process of optimizing experiments before wasting time on the TEM, is of high value. Any microscope with conventional objective lenses can work. We recommend an Olympus BX-51 with objective lenses of 5x, 20x and 50x. For this microscope, we can set you up with a 3D printed stage so that your TEM or SEM holder can be firmly mounted under the lenses.
Clean room fabrication:

Commissioned
research
We are experts in using our own equipment – so why not let us acquire preliminary results for you? Such results will help you clarify if you need to invest in an SEM or TEM holder and will aid in obtaining the needed grants.

Interested in seeing the Nano Channel Chip in action? Either come visit us at DTU in Denmark or have us come to you! Either way, we will show you how the system is prepared and put to use and we will make sure you get your own hands accustomed to operating the system so you can do it yourself if you ever choose to get a system for your lab.
