    Smallest patch clamp setup in the world

Port-a-Patch mini - Patch more. Pay less.

With the Port-a-Patch mini, the world´s smallest patch clamp rig just got even smaller. Built on the success of the Port-a-Patch we miniaturized the patch clamp system even further by integrating the amplifier into the system. Supporting giga-seal recordings from one cell at a time the Port-a-Patch mini offers fast and easy access to high quality patch clamp data with only minimal training. Not only a powerful research tool but also ideal for educational purposes and quick tests of cells and ion channels. The benefits the Port-a-Patch mini include:

  • Small and affordable complete patch clamp rig
  • Test cells and compounds with the minimum of effort
  • Amplifier integrated
  • No patch clamp experience necessary
  • Ideal for teaching
  • Voltage & current clamp
  • Whole-cell & perforated patch clamp
  • Chips produced in-house, various resistances available (customizable on request)
  • Manual and unlimited compound applications
  • High success rates with cell lines; use of primary cells and stem cells also possible
  • Easy to use, minimal training required

Using the Port-a-Patch mini is straightforward and easy – the user simply adds solutions and cells onto the disposable recording chip, where a cell is automatically captured and sealed by suction using a computer controlled pump.

The Port-a-Patch mini system is comprised of the Port-a-Patch mini recording unit with built-in amplifier, a Suction Control unit, and a computer. That’s all.

PatchContol mini: the intuitive Software of the Port-a-Patch mini

The PatchControl mini is a software based on the well-known PatchControl software of the Port-a-Patch and optimized for the Port-a-Patch mini allowing the easiest way to perform your sealing procedure. Equipped with a set of pre-written protocols fitting most user scenarios to obtain a fully automated procedure to rech whole cell configuration, the protocols can also be altered, allowing the entire procedure for cell capture, sealing and obtaining the whole cell configuration to be completely customizable. However, because we know that sometimes you just want to control things yourself, the protocols can be interrupted at any time and the suction controlled manually.

Through innovative communication with the electrophysiology software WinWCP, PatchControl mini can read out important parameters like membrane resistance, whole cell capacitance and series resistance and uses those to perform the pre-programmed automated steps accordingly. Suction strength and duration, voltage and membrane criteria can be set and altered to obtain the optimum parameters for cells routinely used in your lab.

The PatchControl mini software is there to make your patch clamp life easier, from automated cell capture to automated pressure control, the PatchControl mini software can do it all!



Products NPC1 330

The NPC-1 chip is a proprietary innovative product by Nanion Technologies, developed for the Port-a-Patch. It is produced and quality-assured in-house at Nanion headquarters and shipped from Munich to our international customers. Different types of NPC-1 chips are available which should be chosen depending on cell size and application.

The core structure of the NPC-1 chip is a planar borosilicate glass slide with its micron-sized patch aperture. This structure is incorporated into a screw cap for easy handling and minimal cycle times between experiments. Additionally, the unique design of the NPC-1 chip gives similar access to the external and internal solution. Continuous perfusion of the internal solution has finally become possible.

Testimonials & Case Studies

Martin Sumser - Statement about the Port-a-Patch mini

icon papm   "One afternoon is all I needed to get familiar with the features and perform measurements. As an electrophysiologist and university lecturer, I see the Port-a-Patch mini as a great tool to introduce patch clamp to young university students, but also post-doc level scientists in need of a fast, high quality electrophysiology data."

Dr. Martin Sumser, Senior Research Scientist
Ludwig-Maximilians University Munich

Bernhard Stenger - Statement about the Port-a-Patch mini

icon papm   „The new Port-a-Patch mini combines a small and easy set-up with an intuitive software and enabled us to generate data with minimal effort. With the help of a video tutorial we were able to record the effect of AITC on TRPA1 within an hour after setting up the system. This device can be a great tool for testing the effect of compounds on ion channels with the patch clamp technique without spending a lot of time with preparation like priming tubes or pulling pipettes. Especially the possibility of using small volumes (5-15µl) as internal and external solution are an advantage when handling rare and/or toxic substances.”
