RapidPick™ SP Single Pin Colony Picker

Precise, compact colony picking

RapidPick™ SP brings the imaging, colony detection, and picking capabilities of the RapidPick platform to a compact single-pin system.
Designed for labs that need reliable automated colony picking without high-throughput multi-pin capacity, RapidPick SP picks up to 250 colonies per hour with >99% inoculation efficiency. Its compact footprint makes it particularly well suited for benchtop use and space-constrained environments, including anaerobic chambers and biosafety cabinets.
Use RapidPick SP as a standalone colony picker or automate plate loading for greater walk-away operation as throughput needs grow.

Specifications

  • Colony detection and characterization powered by RapidPick software
  • Holds one source plate and two destination plates at a time.
  • The camera takes a single image of the entire plate. No image stitching or cropping.
  • Typical picking speed is 250 wells inoculated per hour.
  • The Pin is sterilized with direct heat. The tungsten construction allows the pin to rapidly cool before being used for picking again.
  • The picker can support NUNC Omnitrays, ANSI/SLAS footprint microplates, and Petri dishes for picking
  • The picker supports most ANSI/SLAS format shallow and deep well plates for the source/destination or for use with plate replication; 24, 96, and 384-well formats.

RapidPick SP — Frequently Asked Questions

What is an automated colony picker?
An automated colony picker uses imaging and software to identify colonies on a culture plate and then physically transfers selected colonies into destination plates or other media. Automation reduces repetitive manual colony picking and can improve consistency, reproducibility, and traceability across microbial screening and isolation workflows.
What is the RapidPick SP colony picker?
RapidPick SP is a compact, single-pin automated colony picker that combines full-plate imaging, automated colony detection and selection, and robotic colony picking. It is designed for laboratories that want reliable automated colony picking without requiring the throughput or footprint of a multi-pin system. RapidPick SP can pick up to 250 colonies per hour with average inoculation efficiency of >99%.
How does RapidPick SP identify colonies for picking?
RapidPick software captures an image of the entire source plate and detects and characterizes potential colonies. Users can define selection criteria based on colony characteristics including size, shape, contrast, and separation, then review or modify the colonies selected for picking.
Does RapidPick SP use AI for colony selection?

RapidPick uses image analysis and user-defined selection criteria to detect and characterize colonies based on morphological and image characteristics. The resulting images and colony meta data can also support more advanced, data-driven workflows in which external analytical or AI models determine which colonies should be selected for downstream processing.

What types of plates can RapidPick SP pick colonies from?

RapidPick SP supports colony picking from Petri dishes, NUNC OmniTrays, and ANSI/SLAS-footprint microplates. It supports common shallow- and deep-well destination plates, including 24-, 96-, and 384-well formats, providing flexibility across microbial isolation, screening, and re-arraying workflows.

How does RapidPick SP prevent cross-contamination between colonies?

RapidPick SP uses a reusable tungsten picking pin that is washed and sterilized with direct heat between picks. The tungsten construction allows the pin to heat rapidly for sterilization and cool quickly before the next colony is picked.

Can RapidPick SP be used in an anaerobic chamber or biosafety cabinet?

Its compact footprint makes RapidPick SP particularly well suited for space-constrained environments, including anaerobic chambers and biosafety cabinets. This makes it an attractive option for microbiology workflows where colony picking needs to take place within a controlled environment.

Can RapidPick SP be automated for walk-away colony picking?

Yes. RapidPick SP can operate as a standalone automated colony picker or be integrated with automated plate handling to increase plate capacity and walk-away operation. For more extensive workflow automation, it can also form the colony-picking component of a RapidPick Connect system.

What applications is RapidPick SP used for?

RapidPick SP is suitable for automated colony picking in applications including microbiome research and microbial isolation, synthetic biology, colony screening and selection, strain development, protein expression, antibiotic and antimicrobial discovery, and other microbial workflows.
