Interscience Spiral Plater - easySpiral Dilute 414000

easySpiral Dilute is an automatic dilutor and spiral plater for Petri dishes that performs serial 1:10 dilutions and plates up to 6 log on a single Petri dish. It automates dilution cycles and plating for microbial enumeration, enabling processing of samples with bacterial concentrations from 30 to 1 x 10^12 UFC/mL and reducing manual dilution steps. Typical applications are routine microbial counts and quality-control enumeration where rapid, reproducible dilutions and plating are required.

Key Features:

• Manufacturer reference: 414 000
• Automatic cycle of 5 successive 1:10 dilutions per run
• Syringe capacity: 1,000 µL
• Predefined deposit volumes: 50 µL, 100 µL and 200 µL
• Counting range: 30 to 1 x 10^12 UFC/mL
• Cycle times: 25 s (sample + 1 disinfection + 1 plating); 134 s (1 disinfection + 5 dilutions + 1 plating)
• Stylet/needle pressure: up to 8 bars

Advantages:

• Automates serial dilutions and plating to eliminate manual dilution steps and reduce handling time
• Supports multiple plating modes (exponential, constant/uniform, circle, mass) for flexible enumeration strategies
• High-precision glass syringe (typical precision 0.5%) for accurate dispensed volumes
• Integrated automatic disinfection (Overflow technology) and long disinfectant autonomy to streamline workflows
• Accepts common diluents (saline, Ringer’s solution) and plates 55, 90 and 150 mm Petri dishes
