UP.SIGHT
Single-cell dispenser with fluorescence and plate imaging for double-assured monoclonality.
A high-throughput single-cell sorter and dispenser that isolates individual microbial cells down to 0.5 µm, even strict anaerobes, with image-based proof. As an alternative to plating, it recovers rare and previously uncultivable strains and it brings new convenience in every strain development project.
Legacy isolation methods are slow and resource intensive. B.SIGHT isolates single microbial cells down to 0.5 µm with image-based proof, recovering rare and previously unculturable species. It can work with strict anaerobes inside a glove box, and purity is verifiable from the first image.
Image-based sorting discriminates single cells from doublets and debris in real time, confirming true single-cell dispensing and proving monoclonality for QA and to reviewers. Purity is verifiable from the first image, no streak-and-check cycle so cultures start monoclonal and pure.
On a streak plate, fast growers win and rare organisms vanish. B.SIGHT gives every cell its own well, free of nutrient competition and antagonism, so fastidious and previously unculturable species finally get a chance to grow.
The first benchtop single-cell dispenser designed for anaerobic work. It moves in and out of a glove box or anaerobic chamber, isolating oxygen-sensitive organisms under the exact conditions they need.
B.SIGHT isolates 1,000+ single microbes in under 30 minutes, reaching hundreds to thousands of verified isolates in a week. Screen more clones faster and rare taxa at <0.1% abundance, invisible to bulk culture, become deterministic to recover.
In their 2022 publication, Afrizal et al. developed and benchmarked an anaerobic, single-cell dispensing (SCD) workflow using the B.SIGHT™. SCD cut time-to-pure-culture from 17 to just 5 days and achieved colony growth in up to 87% of wells.
The workflow recovered 52.2% of total faecal OTU richness, far surpassing the 35.2% reached by traditional methods. It also captured 87% of abundant taxa (>1% relative abundance by 16S), representing 82% cumulative relative abundance of the faecal OTUs.
Using this workflow, they successfully isolated new taxa, including six high-priority "most wanted" taxa as defined by the Human Microbiome Project. This work demonstrates the B.SIGHT™'s potential to unlock previously inaccessible microbial diversity.

Time to pure culture cut from 17 to 5 days
87% colony growth across wells
52.2% OTU richness recovered (vs. 35.2% with traditional methods)
87% of abundant taxa (>1% relative abundance) captured
82% cumulative relative abundance of faecal OTUs recovered
6 novel taxa isolated, including high-priority "most wanted" strains
In short: The B.SIGHT™ workflow delivers faster, more efficient, and more comprehensive microbial isolation, enabling researchers to access valuable bacterial and yeast strains that are difficult to obtain with traditional approaches.
Every isolate begins as a single, imaged cell. Its clonal origin is traceable from the first well.
Include or exclude labelled cells by green fluorescence (488 nm laser; 561 nm on request), alongside cell size and roundness. B.SIGHT sorts on multiple parameters at once, filtering out debris, doublets, and unlabelled cells before dispensing. Inquire for alternative fluorescence options.
The B.SIGHT isolates ~40 cells per minute at 97% single-cell efficiency. Unlike FACS, its low-shear dispensing preserves cell viability, reaching up to 80% of wells showing clonal growth.
Once dispensing is complete, the B.SIGHT automatically releases the multiwell plate and opens the lid, allowing robotic arms to transfer it downstream for further processing in an automated workstation.
The B.SIGHT fits in a biosafety cabinet and uses single-use cartridges to prevent cross-contamination between samples.

“The instrument is handy and super user-friendly. The machine is ready to sort after a quick quality control step and adaption of sort settings. It sorts single cells reliably. Due to the usage of cartridges cross-contamination is not an issue anymore and cells are sorted alive and happy since they are kept in their needed buffer during the entire sort process. An in-built laser enables us to differentiate between fluorescently labelled and unlabelled cells, which makes the whole cell sorting process even more precise.”
“EPFL has developed a new pipeline named parSEQ, designed with the help of CYTENA's B.SIGHT, which aims to optimize the capture of sequence-function datasets from screened protein variant pools. With parSEQ, the functional data of each screened variant is effectively paired with its corresponding sequence data.”
“Our lab uses the B.SIGHT to sort microbial cells from environmental samples. It has a very intuitive user interface and the product managers at CYTENA have been very helpful in optimizing the parameters to suit our needs. It dispenses single cells gently with precision and can fill a 384-well plate in under an hour. The sorting speed and accuracy has greatly maximized our capacity to create large libraries of pure cultures.”
B.SIGHT is used across microbiome research, microbial strain development, and synthetic biology workflows to isolate image-verified single bacteria and yeast at high throughput, enabling confident clonal cultivation and downstream genomic analysis. The following resources show how researchers put it to work.
Label-free single-cell isolation with image-based detection, followed by miniaturized MDA to reduce reaction volumes and costs. Subsequent 16S rRNA sequencing allowed taxonomic classification.
The B.SIGHT enables a high-throughput workflow for isolating anaerobic gut bacteria by dispensing image-confirmed single cells into 96- or 384-well plates. Its compact design fits into anaerobic workstations and supports both liquid and solid media.
Single-strain isolation was carried out using a two-step workflow with the B.SIGHT. This workflow reduces time and cost compared to traditional colony picking, making B.SIGHT a powerful tool for strain isolation.
Unlocks access to previously unculturable microbes, enabling deeper insights into complex microbial ecosystems.
Speeds up engineered strain development by enabling reliable isolation of high-performing microbial clones.
Improves downstream data quality through precise sorting of verified single microbial cells for multi-omics analysis.
Single-cell dispenser with fluorescence and plate imaging for double-assured monoclonality.
Dual-channel fluoroscent and brightfield sorting for precise isolation of labeled cells.
Tipless, low-volume non-contact dispensing with the I.DOT for fast, precise liquid handling with minimal waste across life science applications.
Centrifugal plate washing system, compatible for 96-, 384-, and 1536-well plates.
Yes — B.SIGHT is CYTENA's single-cell dispenser for microbiology and the first with full anaerobic compatibility. It moves in and out of a glove box or anaerobic chamber, isolating microbial cells across 0.5-20 µm, label-free or GFP-tagged, under the conditions they need.
By giving each cell its own well — a competition-free microenvironment with no fast-growing neighbours or antagonistic metabolites — B.SIGHT lets rare and fastidious organisms establish. Isolation is deterministic, reaching taxa below 0.1% relative abundance that bulk culture in plates or liquid culture never surfaces.
Yes. B.SIGHT isolates thousands of clonal starting points in parallel, so you can screen producers and variants, develop novel growth media, and raise the odds of finding the low-frequency, high-value strains behind fermentation, probiotics and live biotherapeutic products (LBPs).
Complex microbiome samples including faecal matter, soil, water, fermented foods and bioengineered microbial cultures have all been processed with B.SIGHT, with exceptional recovery of the microbial diversity, and image-based verification of single-cell isolation for every well.
