Colony picking robots
Robotic platforms that image a microbial plate, score colonies by size, morphology and fluorescence, then pick and re-array 200–3,000 colonies an hour into fresh growth plates — the automated front end of strain engineering, directed evolution, CRISPR clone screening and microbiome culturomics.
1 · What it gives
Colony picking robots are automated microbiology platforms that image a poured agar plate, identify discrete colonies by size, morphology, spacing and fluorescent marker, and use a sterilisable pin-head or single-pin tool to pick each selected colony and stamp it into a fresh growth plate, liquid well or membrane. They replace the manual picking loop at the front end of strain engineering, directed evolution, CRISPR clone screening, antimicrobial discovery and microbiome culturomics, lifting throughput from a few hundred colonies per technologist-day to 200–3,000 colonies per hour with a full audit trail. The platform is mid-transformation along four axes: AI-assisted colony recognition that scores picks on phenotypic and fluorescent criteria rather than size alone; integrated end-to-end microbial screening lines (QPix FLEX) that plate, streak, pick and inoculate in one closed workflow; high-capacity mega-pickers (Singer PIXL Max, KBiosystems K8XL) serving industrial directed-evolution campaigns; and GMP-grade audit and data integrity (21 CFR Part 11) for regulated pharmaceutical microbiology.
The key directions of colony picking robots are:
- Integrated microbial screening lines (QPix FLEX): Molecular Devices’ end-to-end systems that combine plating, streaking, colony picking and re-inoculation under one software suite, with AI colony recognition on phenotypic and fluorescent criteria.
- High-capacity mega pickers (Singer PIXL Max, KBiosystems K8XL): industrial-scale pickers running thousands of picks per hour for directed-evolution, CRISPR and microbiome culturomics campaigns, with multi-channel fluorescence detection.
- Compact benchtop pickers (Hudson RapidPick SP/Lite, Singer PIXL Go!): single-pin or low-throughput systems for academic and mid-throughput labs, expandable to higher capacity via PlateCrane plate handlers.
- GMP data integrity and traceability (21 CFR Part 11): audit trails, electronic records and barcode plate tracking that let colony pickers sit inside regulated pharmaceutical microbiology and quality-control workflows.

Information, not legal advice — confirm the procedure for your product. (2026-10-06)
United States
The United States is the centre of the integrated microbial-screening class: Molecular Devices (San Jose, CA, a Danaher company) builds the QPix family that defined the category, and Hudson Robotics (Springfield, NJ) builds the RapidPick and PlateCrane lines. US pharmaceutical microbiology and synthetic-biology programmes are the primary buyers, and FDA’s 21 CFR Part 11 data-integrity framework is what gives colony pickers a route into regulated quality-control workflows.
integrated screening lines, benchtop pickers, FDA data integrity#
- Molecular Devices — QPix 420 / QPix FLEX: the integrated end-to-end microbial screening system (plating, streaking, picking, re-inoculation) with AI colony recognition, a Danaher company since 2017.
- Hudson Robotics — RapidPick SP/Lite + PlateCrane: compact benchtop pickers (single-pin SP, expandable Lite) integrated with the PlateCrane overhead microplate handler for walk-away automation.
- FDA 21 CFR Part 11: the electronic-records and audit-trail standard that qualifies colony pickers for GMP pharmaceutical microbiology and QC.
European Union
Europe anchors the high-capacity mega-picker and academic-benchtop class: Singer Instruments (Watchet, UK) builds the PIXL Series (PIXL Go!, PIXL+, PIXL Max) and the ROTOR repertoire-transfer system; KBiosystems (Basildon, UK) builds the K6 and K8XL mega pickers for industrial directed-evolution and microbiome culturomics campaigns. EMA’s ICH Q2(R2) and GMP Annex 1 frameworks complete the regulated microbiology picture.
mega pickers, repertoire transfer, EMA GMP microbiology#
- Singer Instruments — PIXL Series + ROTOR: PIXL Go!/+/Max colony pickers with multi-channel fluorescence, plus the ROTOR repertoire-transfer system for yeast and microbial arraying.
- KBiosystems — K6 / K8XL mega pickers: high-throughput industrial pickers for directed-evolution, CRISPR clone screening and microbiome culturomics.
- EMA ICH Q2(R2) & GMP Annex 1: the analytical-procedure and aseptic-processing framework that qualifies pickers for regulated European pharmaceutical microbiology.
China
China is the demand-side growth market for colony picking robots: a fast-expanding synthetic-biology industry (CRISPR strain engineering, directed evolution, microbiome culturomics) and a large antimicrobial- discovery and vaccine development base are converting manual picking loops into automated picker lines. NMPA’s adoption of ICH Q2(R2) and 21 CFR-equivalent data-integrity expectations frames the regulated route, but the picker OEM base remains substantially imported (US and UK), so the Chinese regional block is held qualitative.
synthetic-biology demand, NMPA data-integrity alignment, imported OEM base#
- Domestic synthetic-biology build-out: CRISPR strain-engineering and directed-evolution programmes in industrial enzyme, fine-chemical and biopesticide firms drive automated picker procurement, mostly QPix and Singer lines.
- NMPA ICH Q2(R2) / data-integrity alignment: harmonised analytical-procedure and electronic-records expectations qualify pickers for regulated pharmaceutical microbiology.
- Imported OEM base: the picker OEM layer is predominantly US (Molecular Devices, Hudson) and UK (Singer, KBiosystems); domestic firms localise plate preparation, media and downstream assay rather than the picker itself.
