Scalable automation of sample prep

For spatial biology and flow cytometry — so your team can focus on science, not pipetting.

Trusted by industry-leaders around the globe

What we do

Automation across four areas

Spatial biology automation

Dewaxing, antigen retrieval, staining and panel mixing on one instrument. Eleven validated workflows from H&E to PhenoCycler, GeoMx and Visium.

Flow cytometry & single cell

Panel mixing, staining and washing for cell suspensions. Up to 96 sub-panels in a run, 96 cryovials thawed in ten minutes hands-on.
Learn more
Lab-in-the-loop

Built for the future of AI in the lab. Both platforms speak an open REST API, so your own software — or your agent — can design and run protocols alongside your team.

Digital pathology & AI
In development

Models are only as consistent as the slides they learn from. Reproducible, standardised sample prep is the prerequisite — and where we're heading next.

Whom it's for

Built for the people who run the samples

The same instruments, doing rather different jobs depending on who is standing in front of them.

Academia

Reproducibility you can publish.

A protocol should run the same way in June as it did in January, and the same way after the postdoc who wrote it has moved on. Automation makes that the default rather than something a lab has to defend in review. And it does it without a dedicated automation hire — the instrument absorbs the work, so the people are free for the science.
Core facilities

One protocol, every operator.

Serving many principal investigators means the same assay has to come back the same way whoever is on shift, and staff turnover cannot be allowed to show up in the data. Automated runs make the protocol the constant instead of the operator, which shortens training and makes results comparable across projects. Reagent inventory is tracked as runs proceed, so the facility knows what it has without a manual count.
CROs

Throughput with an audit trail.

Client work has to be both fast and defensible: consistent execution across studies, and a record that stands up when someone asks how a sample was prepared. Run logs and user accounts supporting 21 CFR Part 11 mean the traceability is a property of the instrument rather than a spreadsheet someone maintains alongside it.
Biotech & pharma R&D

Scale without variability.

The methods that work for a pilot are usually the ones that break when a study gets large enough to matter — variability that was tolerable across twelve samples becomes the finding across hundreds. Standardised prep holds the protocol steady as volume grows, and an open API means the platform fits into pipelines and analysis you already run rather than sitting beside them.

What researchers say

Testimonials

“…auto staining enables testing more conditions and finding the optimal one.”

Dr. Noemi Kedei Staff Scientist, NIH

“With the Parhelia Omni-Stainer I’ve been able to increase the number of coverslips or slides I can do CODEX staining at the same time and, on top of that, I’ve been able to save reagents and antibody while preserving staining quality. Using their product was a great investment for our project.”

Dr. Ruan Medrano Senior Scientist, Washington University in St. Louis

Partnerships

Announced in July 2026, our partnership with Sirona Dx brings the Spatial Station together with their technology-agnostic spatial biology expertise — spanning cyclic immunofluorescence and imaging mass cytometry, from discovery research through clinical development. The aim is straightforward: better reproducibility, higher throughput and lower cost across studies and sites.

We are working with Quanterix to bring automated PhenoCycler-Fusion and Opal workflows to their customers, so labs running those assays can move to hands-off sample prep without leaving the chemistry they already trust.
Parhelia Bio is pleased to be partnering with Hamilton to bring the next generation of sample automation for spatial biology and flow cytometry with the Parhelia Spatial Station™.
Parhelia Bio is pleased to be partnering with Opentrons to offer competitive pricing on a complete tissue auto-staining solution. Omni-Stainer™ is compatible with most liquid handling robots, but if you don’t have one, we recommend our partner Opentrons OT-2.
