Prova S1 is a microscope slide in the standard 75 × 25 mm footprint with sensors, a clock and memory sealed into its frosted label end. It is designed to record the temperature, time and handling a slide goes through from microtome to scanner, and to keep that history as a signed record you read with a phone.

Not yet. S1 is in development. You can reserve S1 for your lab for free on this page.

S1 is designed to record multi-point temperature, elapsed time at each step, three-axis motion such as loading, transfers, tilts and drops, and its own unique identity. Every reading is time-stamped and written to an append-only record that is signed on the slide.

How do I read an S1 slide?

Hold an NFC-capable phone to the slide's label end and open the Prova app. There is no reader, cable or network install.

Will S1 work with my instruments?

S1 keeps the standard 75 × 25 mm footprint so it can follow the same racks, carriers, stainers, coverslippers and scanners as other slides. Compatibility is a design goal and requires validation on each instrument.

Prova S1Capture what you can’t see.

A slide that records the heat, time and handling your patients’ tissue goes through, from section pickup to scan.

Your lab records what’s on the slide. S1 records what happened to it.

Images, reports, LIS fields and instrument logs tell part of the story. S1 adds the slide’s own record of temperature, elapsed time and handling.

Prova captures the ground truth you can’t see.

A protocol says what should happen. S1 records what did, at the slide, on every run.

The Prova Record™

Know which slide, when, and by how much.

Read the slide

Hold the top edge of your phone against S1’s label end. Keep it still until the read is complete.

Read S1

Follow your phone’s scanning prompt.

When something goes wrong, know where to look.

Find the step.

When a stain is weak, review the recorded conditions to see which steps need a closer look.

Have the record ready.

When a result is questioned, the slide’s Prova Record™ is already there.

Show your work.

Bring the slide’s recorded history into QA reviews, investigations and inspections.

Ground truth can’t be scraped. It has to be measured.

Every S1 adds a measured history to your lab’s record. It compounds with every run, and it’s the kind of evidence images and logs can’t supply.

Built for the lab you already run

Designed to go where your slides go.

S1 keeps the standard 75 × 25 mm footprint and is designed for the baths, dryers, stainers, coverslippers and scanners you already use.
