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

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.
Callisto is For Research Use Only. Not for use in diagnostic procedures. Oxford Nanopore products are RUO. Regulatory status and claims regarding third-party products are the responsibility of the third party.

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

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.
