ASI S Series Automatic Sampling Instrument

Fully Automatic Operation & High Sampling Timeliness

Powered by stable Siemens PLC and 10-inch capacitive touch HMI, this bioreactor automatic sampler realizes unattended full-automatic sampling. Users can customize sampling frequency freely and activate long-term automatic continuous sampling, capturing samples precisely at every critical time point of fermentation cycles. It eliminates delayed sampling and missed data caused by manual operation, greatly improving the timeliness and integrity of bioprocess monitoring data for overnight and long-cycle fermentation experiments.

3 Sampling Modes to Fit Diverse Bioprocess Application Scenarios

Three switchable independent sampling modes are integrated inside the fermenter sampler to meet differentiated lab testing demands. Supporting 4 independent sampling channels and simultaneous connection to up to 4 fermenters, the device adapts seamlessly to strain screening lab trials, mammalian cell culture pilot tests, recombinant protein fermentation verification and other synthetic biology & biopharma research scenarios with outstanding versatility.

Sealed Vial Sample Storage to Boost Sample Test Reliability

All collected samples are sealed in independent airtight vials for retention, isolating samples from air exposure, microbial contamination, volatilization and oxidation. Matched with low-temperature refrigerated storage function, the sampler effectively preserves cell activity and stable metabolite concentrations, minimizing detection deviation in downstream HPLC and biochemical analysis to deliver highly reliable experimental results.

Multiple Optional Sample Retention Specifications for Flexible Matching

This automatic sampling instrument supports compatibility with various sizes of sample vials, featuring adjustable sampling volume ranging from 1 mL to 8 mL and standard 16-position 10 mL sample rack. It fits common mainstream analytical equipment perfectly without extra secondary subpackaging steps, simplifying pre-processing workflows in biotech laboratories.

Aseptic Docking with Fermenters Without Disturbing Fermentation Experiments

The sampler adopts fully closed aseptic pipeline connection with bioreactors. Its high-temperature & corrosion-resistant silicone sampling tubes and connectors can undergo integrated sterilization together with fermentation tanks. The whole sampling and sample retention workflow maintains sterile tank internal environment, avoids bacterial intrusion, and causes zero interference to dissolved oxygen, pH, cell density and other core fermentation parameters during bioprocess running.

Biopharma GMP Pilot Cell Culture

Aseptic automatic sampling for antibody, recombinant protein fed-batch/perfusion culture; low-temperature sealed samples meet GMP traceability standards for upstream process QC.

Synthetic Biology & Strain Screening Labs

4-channel parallel sampling for engineered bacteria/yeast long-cycle evolution experiments; consistent timed sampling ensures parallel group data comparability.

Bioprocess Validation & Batch Consistency Testing

Standardized repeatable sampling for process validation; auto sampling logs complete batch records for cross-shift overnight fermentation runs.
