BE-TRANSFLOW CUSTOM (10 devices per box)


BE-Transflow: is our most versatile cell culture platform. It allows the study of complex culture configurations by joining a culture well with a microfluidic channel via a porous membrane. This is the optimal device for Air Liquid Interface (ALI) culture, endothelium/epithelium barrier and crosstalk studies.

*Without  taxes
What pore size would you prefer?

Options: 1, 3, 5, 8 µm.

Select the porous size that best suit your applications or contact us to use your own membrane in the device.

Are you an expert in fluorescence measurements?
Options: Black, transparent

We offer a black option for every top piece of the BE-Transflow for optimal contrast and elimination of spurious high-power laser reflections.

Are you going to perform Crosstalk experiments?
Options: 1, 2 wells/channel

Contact us for beta testing our new prototype chip based on the BE-Transflow for crosstalk experiments.

Does your application needs for specific shear stress, flux and pressure values?
Channel width 1.1 – 5.7 mm

Channel height: 0.2 – 1 mm

Select de optimal shape of the microchannels to recreate the perfect physiological environment in terms of shear stress, flux and pressure inside the chip.

Do you use functionalized or micropatterned surfaces, or even sensors in your culture?
Options: Plastic base, adhesive base

Acquire the BE-Transflow system with a biocompatible adhesive instead of the plastic base and glue it on a biocompatible plastic or glass surface prepared for you application (micropatterned surfaces, lithographed sensors or electric stimulation systems). For more information contact us at


Culture models

Perform Air Liquid Interface (ALI) experiments on a 2D or 3D culture with automatic culture medium replacement for systems such as epithelial cultures, toxicity tests, absorption test and much more.

Create the perfect endothelium endothelium-epithelium barrier: Use the upper well for the 2D or 3D epithelial culture and seed the endothelial cells in the perfusable channel underneath. Most common applications are Blood Brain Barrieer (BBB), gut, skin, lung and many more.

Crosstalk studies (prototype): Explore the cross-talk of two cultures in an automated and simple way using the BE-Transflow option that connects two wells in the same channel. Most common application are indirect toxicity studies. This chip is a prototype and is available at a higher price than the normal BE-Transflow.



BE-Transflow has been designed with ALI in mind. Its an ideal chip for ALI culture and coculture research (skin, cornea, gut, lung). However, its simplicity to use makes it also a very useful tool for any coculture research and crosstalk experiments.

Example Applications

Epidermis/dermis coculture: Recreation of the epidermis and dermis in the well of the BE-Transflow device. In the upper part of the image and marked in blue are the nuclei of the keratinocytes (HEKa) forming the epidermis. The HEKa cells were cultured for 21 days in the ALI to create a mature epidermis. Underneath the epidermis we can see the fibroblasts in red embedded in a collagen matrix, mimicking the dermis. The scale bar marks 100 µm.

Bone on chip: Beonchip participates in the Eurostars project BONAFIDE. This project is devoted to the production of a human bone-on-chip platform that will simulate bone growth, resorption and remodeling for future evaluation of (anti-osteoporosis) drugs and biomaterials (e.g. bone cements). The culture well represents the catabolic side (bone resorption) where the osteoclasts rest in contact with a bonelike scaffold. The lower channel represents the anabolic side of the bone model. This channel is seeded with osteocytes and osteoblast that form a 2D tissue. This tissue is mechanically stimulated by the controlled laminar flux applied in the channel, mimicking the physiological environment of the bone. The bone remodeling process is automatically analyzed using image analysis software and biomarker analysis.





Device features

  • Easy to use: Be-Transflow is compatible with any type of optical microscopy and its slide format has been chosen for easy handling under a microscope.
  • Easy to implement: Be-transflow wells are positioned in standard positions of a 96 well plate for its use in automated microscopes. In addition, their volume is identical to the one of those wells in order to ease the transition to the transflow device.
  • Easy to connect: Transflow is compatible with all microfluidic flow control systems (syringe, peristaltic pumps, pressure control systems, rocker systems…).
  • No unspecific absorption: Unlike in other PDMS devices, Be -transflow is made of lipophobic thermoplastic materials and does not present unspecific drug absorption issues. Therefore, it allows inmunohistochemistry with fluorescent detection.
  • Cell recovery option: The cell cultures used in the Be-Transflow can be easily recover for further experimentation as well as extracting the membrane with cells for histological processing.
