an autosampler for sample depositing and storage

lab sampling and sample preparation in bioprocess development are often done manually. therefore, deviations can occur, results are timely delayed, recorded manually and missing during weekends and nights. numera® is a modular system which provides an integrated and customized process analytical technology (pat) improvement. it enables on-line analytics for reliable results in real-time 24/7. combined with lucullus, the entire workflow of sampling design, systematic sampling automation, bioprocess monitoring, and feedback control is covered by an all-in-one solution.

application

on-line analytics

the samples are automatically transferred to various directly coupled analytical devices. analysis is started trough re-mote control and results are collected from our software lucullus pims. cell-containing samples are passed to cell analyzers or flow cytometers. filtrated samples are directly injected in an hplc or transferred to enzymatic bio analyzers.

sample storage

samples are collected and stored in cooled conditions in the sample collector. the size of the sample collector can be adapted to specific needs based on different volumes, numbers and types of vials.it performs additional liquid handling steps, if needed. each vial is labeled with a unique barcode and sample id for distinctive identification in subsequent analytics.

sample processing

with the dilution module, biomass-containing samples are precisely diluted over a wide range. the simultaneous addition of reagents is used to perform protein precipitation, product extraction or staining reactions. the biomass-containing samples are filtrated with a unique filtration module with maximum sample yield. cross-contamination is prevented by using a new filter section for each sample. the variety of available filter membranes allows to meet specific requirements, regarding cell-densi

sampling

biomass-containing samples are drawn automatically from stainless steel and benchtop glass bioreactors maintaining their sterility. volumes up to 2 ml are drawn with minimum sample loss. using multiplexer modules, up to 16 bioreactors or downstream devices are coupled independently, each connected with a sample line of up to 10 m length. the sampling frequency lies between 6 and 15 minutes only, depending on sample processing steps.
