ASI A Series Automatic Sampling Instrument

Fully Automatic Sample Sampling & Retention Workflow

The device delivers unattended automatic sampling and sample storage in one unit. It connects seamlessly with bioreactors, supports adjustable sampling frequency and continuous auto-sampling without manual intervention, eliminating human operation errors and ensuring consistent sampling timing throughout long-term fermentation runs. It features flexible sampling volume ranging from 1 mL to 8 mL, adapting to different analytical test standards.

Refrigerated & Frozen Dual Low-Temperature Sample Storage Modes

Equipped with precise temperature-controlled sample retention system, the ASI sampler provides both refrigerated and frozen storage conditions post-sampling. Low-temperature environment effectively stabilizes sample composition, preserves cell activity, metabolite concentration and biological integrity, preventing sample degradation during waiting periods before offline lab analysis.

Wide Compatibility with Diverse Sample Retention Specifications

This sampling system offers strong adaptability to various sample tube, vial, and container specifications. It supports different sample holding volumes, tube sizes, and preservation container types, and is compatible with common downstream analytical equipment, including HPLC, mass spectrometers, and biochemical analyzers, with flexible customization options to meet unique laboratory sample retention requirements.

Key Advantages for Bioreactor Systems

The base model supports connection to a single bioreactor and features dual sampling modes to cover all mainstream bioprocess application scenarios. Combined with automatic continuous sampling, adjustable sampling frequency, and temperature-controlled preservation, the ASI sampler provides a complete, closed-loop sampling and retention workflow for microbial fermentation, cell culture, and biopharmaceutical process development.
