Introducing VoltaHyb:
Automating the Last Mile of Targeted Sequencing Workflows
The Volta Labs team is revolutionizing critical targeted sequencing workflows with the introduction of the VoltaHyb™ suite of Apps and kits for the Callisto™ Sample Prep System. Designed to enrich your targets with confidence every single time, the Callisto platform brings unmatched workflow simplicity to hybridization capture. With Callisto, users no longer need to rely on multiple lab instruments (heated blocks, magnetic racks, vortexers) or perform time-sensitive heated transfer steps - such complex steps are abstracted away from the end user. Furthermore, Callisto's unique architecture enables precise magnetic bead manipulation coupled with uninterrupted and uniform temperature control during the hybrid capture enabling consistent enrichment performance.
Callisto reduces sequencing redo rates to less than 3% while minimizing sample loss throughout the capture process. This breakthrough approach enables reliable targeted sequencing even for challenging applications where conventional tools struggle. These advantages extend across both long and short read-based hybrid capture workflows.
The scalable architecture of the Callisto system enables flexible throughput, with the capacity to process up to 96,000 exomes per year or 48,000 PacBio HiFi samples annually. Whether you're running a small research lab or a high-volume testing facility, Callisto adapts to your needs with flexible batch sizes and consistent performance.

VoltaHyb’s Expanding App Menu
At Volta, we’re continually growing our support for hybrid capture workflows across both short- and long-read sequencing platforms.
On the short-read side, Callisto currently supports IDT xGEN v2 chemistry, as well as Twist’s standard v2 and Fast chemistries. For long-read applications, we support PacBio HiFi enrichment based on Twist’s standard v2 chemistry.
There are more Apps coming to the VoltaHyb menu, and we’re always listening to our users. If there’s a hybrid capture chemistry you’d like to see automated on Callisto, let us know—we’d love to hear from you.

Real-World Impact for Applied Genomics
The combination of Callisto automation and Oxford Nanopore sequencing delivers what laboratories have been seeking: a way to scale advanced sequencing technologies without the traditional automation headaches. This is particularly valuable for service laboratories, clinical laboratories, and research institutions looking to incorporate nanopore sequencing into routine workflows.
"Nanopore sequencing represents a transformative approach to genomics, and we're committed to making these powerful technologies as accessible as possible," says Udayan Umapathi, founder and CEO of Volta Labs. "With our Oxford Nanopore LSK114 app, we're extending the same automation convenience that has transformed other sequencing workflows to nanopore technology. Labs can now leverage these capabilities with unprecedented ease and consistency."
Early Adoption Success
Early access partners have already begun to see significant improvements in both efficiency and library quality using the automated LSK114 workflow. The ability to consistently produce high-quality Oxford Nanopore libraries without traditional automation complexity is proving transformative for laboratories scaling their sequencing programs.
The improvements go beyond just efficiency—we're seeing substantial reductions in failed library preparations and improved consistency across different operators, critical factors for laboratories where reliability and reproducibility are paramount.
