Benchtop sample prep instrument

The Callisto™ Sample Prep System. Right the first time.

Callisto Sample Prep System benchtop instrument, closed front view

Callisto automates extraction, library prep and hybrid capture on one benchtop system. A new chemistry is a kit you load, not a new instrument you buy.

Why Callisto

A new chemistry is a kit you load, not a new instrument.

✓
No new instrument

Add apps as kits on the Callisto™ you already have.

✓
No re-automation project

Each app is already automated on Callisto.

✓
No new method development

Load the kit and walk away.

How it works

Load the kit. Walk away.

Callisto Sample Prep System, closed front viewWatch the demo
Step 1
Load

Load the app’s kit and your samples on Callisto.

Step 2
Run

Start the app on the touchscreen. Callisto runs it walk-away.

Step 3
Collect

Take your output off the deck: extracted DNA, sequencing-ready libraries or captured libraries.

Step 4
Continue

Run the next app on the same Callisto, or go straight to your sequencer.

Fit for your lab

Sized for a benchtop. Batches that match your runs.

On your bench

Callisto sits on a stable lab bench and runs on standard 100–240 VAC power. Full dimensions are in the specs below.

Up to 24 reactions per run

Up to 24 reactions per run is the platform maximum. Some apps run smaller batches; Twist Fast Hyb Cap runs 4 reactions per run.

Your sequencers

Library prep apps cover AXELIOS 1, Illumina, Oxford Nanopore, PacBio, Element and Ultima Genomics. See by sequencer

FAQ

Questions about Callisto

What is the Callisto Sample Prep System?

Callisto™ is a benchtop sample prep system from Volta Labs that automates extraction, library prep and hybrid capture in walk-away runs, with 14 released apps. For Research Use Only. Not for use in diagnostic procedures.

What is a Callisto app?

An app is an automated protocol and the reagents you load on the same Callisto instrument, so adding a new chemistry or sequencing technology means buying a kit, not a new instrument.

Which sequencers do Callisto apps support?

Callisto library prep apps cover AXELIOS 1, Illumina, Oxford Nanopore Technologies, PacBio, Element and Ultima Genomics sequencing. Each app page lists its compatible sequencers.

How many reactions can Callisto run at once?

Callisto supports up to 24 reactions per run. Some apps run smaller batches; Twist Fast Hyb Cap runs 4 reactions per run.

How big is the Callisto instrument?

Callisto measures 66.8 cm (H) × 92.7 cm (W) × 84.6 cm (D), is 90 cm tall with the door open, weighs 70.3 kg and needs a stable lab bench and 100–240 VAC, 50/60 Hz power.
