Why labs are switching

The real cost of JuLI Stage

JuLI Stage is a solid instrument – but its size, required desktop PC, and lower resolution add cost and complexity that many labs don't need.

💸
Requires a dedicated All-in-One Desktop PC

JuLI Stage ships with a bundled touchscreen desktop PC (Intel Core i5, 23" monitor). That's extra hardware to manage, extra desk space, and more IT overhead. zenCELL owl connects via a single USB-C cable to your existing laptop.

🔒
18kg – not easy to move between incubators

At 429×310×324mm and 18kg, moving JuLI Stage between incubators is a two-person job. zenCELL owl weighs 1.5kg and fits on any shelf – equip multiple incubators without logistics headaches.

📦
2.8MP camera limits morphology detail

JuLI Stage uses a 1,936×1,456 pixel CCD sensor (2.8MP). zenCELL owl delivers 5MP – nearly double the resolution for more precise confluence analysis, scratch assays, and morphology work.

What researchers say

Labs that switched from expensive systems

★★★★★

"zenCELL owl has considerably helped our research projects – timelapse imaging of various cell phenotypes in 2D and 3D without opening the incubator door."

Research Team
University Research Institute
★★★★★

"We monitor our PC12 cells constantly and check performance each time. Reliable, reproducible, and the price made it possible to equip multiple incubators."

Biotech Company
Austria
★★★★★

"Wound healing assays can be monitored so fast and constantly. With small adjustments you can reduce the analysis time enormously."

Questions about switching

zenCELL owl vs. JuLI Stage – FAQ

Is zenCELL owl really comparable to JuLI Stage? +
For the majority of brightfield live-cell imaging applications, yes – completely. zenCELL owl delivers higher image resolution (5MP vs 2.8MP), requires no dedicated PC, weighs 12× less, and costs approximately 3× less. JuLI Stage offers multi-channel fluorescence (GFP, RFP, DAPI) which zenCELL owl does not currently support. If your work is brightfield-based – confluence, migration, cytotoxicity, spheroid monitoring – zenCELL owl is the smarter and more affordable choice.
Can zenCELL owl do fluorescence imaging like JuLI Stage? +
zenCELL owl is a brightfield (transmitted light) system and does not currently support fluorescence imaging. JuLI Stage supports triple fluorescence (DAPI, GFP, RFP). If fluorescence channels are essential for your specific assay, that is the key technical differentiator. For all brightfield applications, zenCELL owl is a complete and higher-resolution alternative.
Do I need to buy a new PC to run zenCELL owl? +
No. JuLI Stage ships with a dedicated All-in-One touchscreen desktop PC. zenCELL owl connects to your existing laptop or desktop via a single USB-C cable. No additional hardware purchase required.
Does zenCELL owl support 96-well and 384-well plates like JuLI Stage? +
Yes. With the motorized XYZ stage add-on, zenCELL owl fully supports 6-, 24-, 96- and 384-well plates as well as T-flasks and dishes. Multiple imaging points per well are possible for higher statistical coverage – identical to JuLI Stage's multi-position monitoring.
Are there hidden costs like JuLI Stage's software? +
No. The zenCELL owl software is included in the device purchase price. ImageJ integration is completely free and open-source. There are no annual licence fees, no subscription costs and no mandatory service contracts. The price you see is the price you pay.
Can I get a demo before purchasing? +
Yes – we offer fully remote live demos twice a week, showing zenCELL owl inside a real incubator with live cells. You can see AI cell counting, XYZ stage navigation and the full software in action. Book your free demo below.
