Folistech Autosampler for TOC Analyzer | Automatic Sample Injection System
Manual TOC injection suffers from poor repeatability, low efficiency and human errors. Air suction, inconsistent sampling and long-time on-site operation bring extra burden to lab technicians. Contamination risks also arise from inadequate needle cleaning, while limited sample capacity cannot meet batch testing demands.
Compact 24-position autosampler, ideal for labs with small daily sample batches.
30-position autosampler, balanced capacity for routine TOC water testing.
36-position autosampler, suitable for medium-volume continuous batch analysis.
Features of our TOC Autosampler
Multi-language switchable touch interface for straightforward setup and operation.
Smart liquid level sensing identifies sample surface accurately to avoid air aspiration.
