Your personal ELISA automation. Crocodile is a compact, fully automated, high performance ELISA workstation for low to medium throughput. Under normal circumstances, running ELISA assays required over an hour of your attention, making it difficult to plan other activities. Crocodile provides the functionality of five individual instruments in a footprint similar to a standard stand-alone reader (only 26.5 cm wide). By eliminating the need to move plates between dispenser, washer, incubator, shaker and reader, Crocodile reduces assay times and allows you to perform other important activities.
Key Benefits
Compact & Space-Saving
Only 26.5 cm wide. With reagent bottles placed beside the instrument, it requires no more than 40 cm of bench space—the width of a typical ELISA reader.
Walk-Away Automation
Designed for truly unattended operation. Simply insert the sample microplate (including standards and samples), choose the assay protocol, and leave the work to Crocodile.
Easy Hardware Setup
All functional modules are housed in one compact box. Simply connect the unit to power and a PC. Tubing for wash and waste liquids is preinstalled and ready to be introduced into the bottles.
Fast Start & Easy Maintenance
Wash, waste, and reagent bottles are readily accessible right next to the instrument with minimal startup time. Simply flush the tubing system after every use. Components are easily accessible for maintenance.
Open System & Validation
Adapts to any ELISA format (sandwich, competitive, or other). Accommodates reagent bottles of any shape and size. Supported by comprehensive 3Q Package (Installation, Operation and Performance Qualification) for easy validation.
Regulatory Compliance & Software
Developed according to DIN ISO 13485 with thorough risk analysis. Each unit undergoes extensive testing with certificate of analysis. User-friendly software adapts to any ELISA protocol with flexible, intuitive step programming. Optional Mikrowin software available for advanced curve fitting, automation and CFR 21 Part 11 compliance.
