What are B-grade products and why would I want to buy them? 

B-grade products are products that have imperfections and would otherwise be thrown out in the garbage. We are passionate about minimizing waste, so rather than throwing out products that are not absolutely perfect, we prefer giving them a second chance! You can get a really great deal for a product that will definitely work, but might not be perfect. For example, B-Grade OMEGA products might have some clogged microchannels or air bubbles trapped in their PDMS structure. We do guarantee that you will get at least one functional experiment out of the B-grade product! Buying B-grade products is ideal if you are just setting up a new experiment or trying out a new device that you might not have ever used before. We know that things don’t always go to plan the first time around! It’s a great deal and you help reduce waste.

Please note that B-grade products are not always available (obviously we try really hard to avoid making devices that are anything but perfect). If we currently don’t have a B-grade product listed that you are interested in, send us a request to double-check our stocks by filling out the Ask A Question form here, sending us an email to [email protected], or chat with us in the Live Chat.

Can I reuse my devices?

It depends! Our EB generation devices are virtually indestructible and you can reuse them many times over. Simply rejuvenate them (How do I regenerate my EB generation device?) and keep making beautiful EBs!

Devices of the OMEGA series are also made from similar inert materials, however, we do not recommend reusing the devices since the microchannels themselves are really difficult to clean given their small size. That being said, glass and PDMS are resistant to many solvents, so if you want to give it a try anyways (especially if you are not yet performing experiments that you plan on publishing), you can try a series of washing steps starting with water, isopropanol, acetone, isopropanol and water again. 1M NaOH might also be an option, but is a very harsh cleaning method and might damage the PDMS if applied for too long.

Sterilizing cleaned devices can be ideally achieved using oxygen plasma, but also by steam sterilization (i.e. heat), and by UV or ozone treatment.

Are the shipping vials (squeeze pop bottles) recyclable?

Yes, they are! But before recycling them, remember the second of the three Rs: Reuse! They are autoclavable, so you can safely repurpose them in the lab. If not in the lab, then maybe at home?! Paper clips, pills, candy, screws...

How are OMEGA devices different from conventional neuronal co-culture devices?

Simply put - you can get more and better data faster! Here are the three main reasons why you will love working with our OMEGA devices:

1) All OMEGA devices come ready to go! No need to sweat! No need to use plasma treatment! No need to bond anything! Just coat, seed and you’re done!

2) More experiments per device! Our OMEGA devices are designed to increase your data output without breaking the bank. Thanks to our unique design and manufacturing methods, we can squeeze in more experimental setups per area than conventional compartmentalized devices. We are continuously adding more formats to the webshop, so check back often and keep your eyes peeled!

3) The unique open-chamber design of all OMEGA devices gives you direct access to your cultures. Now you can explore new types of experimental paradigms not possible with standard closed-chamber devices. For example, the chambers are large enough to house tissues that are several millimeters in diameter, easily accommodating tissue explants or self-assembled 3D cultures (e.g. spheroids, organoids). Additionally, conventional patch-clamp electrodes can openly access the cultures, so that you can examine the electrophysiological properties of the culture. OMEGA lets your experimental creativity flourish!

What’s the difference between the OMEGA and the OMEGAACE?

The original OMEGA features two chambers which are physically separated by a series of microfluidic channels. The small size of the microchannels serve to fluidically isolate each of the adjoined chambers, but are large enough to allow neurites/axons to project into and interact with cultures located in the adjacent chamber. The ability to isolate chambers makes the OMEGA ideal for neuronal co-culture and compartmentalization studies. The OMEGAACE has all the advantages of the two-chambered OMEGA with the added versatility of a third accessible chamber. In triple co-culture applications, each chamber is used to culture a distinct cell type. In the context of compartmentalization experiments, the extra chamber is especially useful for fluidically separating neurons into three components: somatic, proximal axonal and distal axonal (growth cone). Going further, each of the separated chambers allow molecules of interest to be applied to a specific component of the neuron.

What's the difference between the OMEGAACE and OMEGAAG?

The OMEGAACE features three chambers with two microfluidic interfaces. In triple co-culture applications, each chamber can be used to culture a distinct cell type (e.g., motor neurons, oligodendrocytes and skeletal muscle). In the context of compartmentalization experiments, the chambers serve to fluidically separate neurons into three components: somatic, proximal axonal and distal axonal (growth cone). For example, the separated chambers can then be used to apply molecules of interest to a specific component of the neuron.

The OMEGAAG features four chambers with four microfluidic interfaces arranged around a central viewing chamber. Each of the four chambers connect the to the central viewing area via microchannels. The flow of fluid across the microchannels into or out of the central viewing area is controlled by simply adjusting the relative fluid volumes (How does fluidic isolation work and when do I use it?) in each of the chambers. Consequently, the viewing area becomes a mixing chamber where molecules of interest that have been added to the source chambers will produce a long-lasting and uniform chemical gradient across the viewing area. The OMEGAAG device has been specifically designed to help researchers study axon guidance and chemotactic factors in vitro.

How does fluidic isolation work and when do I use it?

Fluidic isolation limits the flow and diffusion of solution/molecules between two neighboring culture chambers that are interconnected with microfluidic channels. In this way, the small size of the microchannels can serve to fluidically isolate two connected chambers, but still permit neurites or axons to project across into the adjacent chamber.

Fluidic isolation is achieved by imposing a directional flow of fluid across high resistance microchannels, which is most easily controlled by adjusting the relative level of fluid in each of the chambers. Differences in fluid levels in the two adjacent chambers provide the force required to drive fluid to flow from a chamber with a relatively higher fluid level towards a chamber with a relatively lower fluid level. The unidirectional flow across the microchannels created by this asymmetrical volume loading can serve to fluidically isolate the chamber with the relatively higher fluid level from any adjacent chambers containing relatively lower fluid levels. The unidirectional flow will persist until the fluid levels in each of the chambers equalizes, at which point the directionality of flow will subside. Having reached an equilibrium, a slow bidirectional mixing of fluids will then occur between chambers.

In our testing, the unidirectional flow across the microchannels in the OMEGA devices can be maintained for 40+ hours without adjusting chamber volumes. Since the flow across the microchannels will be towards the chamber with the relatively lower fluid level, the chamber with higher relative fluid level will not be exposed to molecules that have been specifically added to the chamber with the lower fluid level. However, the chamber with lower fluid level will be exposed to molecules that have been specifically added to the chamber with the higher fluid level.

For more information please check the OMEGA user guide for your product.

How much time do I have to exchange the solutions of my OMEGA device?

Not more than a few minutes! It is crucial to prevent the microchannels from drying as this will cause them to lose their hydrophilic property. If the microchannels do dry, the device can be rejuvenated. This process involves thoroughly rinsing the device with deionized water, allowing it to dry completely, then oxidizing and sterilizing the device using a plasma or UV/ozone cleaner.

How often do I have to refill the water in the evaporation minimizer?

Verification frequency of fluid levels inside the OMEGA device and the evaporation minimizer will mostly depend on the incubator environmental conditions and on the number of times the culture is removed from the incubator. For example, improperly humidified incubator environments (<80 % humidity levels) will lead to increased evaporation from the wells. We recommend verifying the fluid level in each well of the device as well as within the evaporation minimizers every 2 days, and refilling when required.
