Benchtop Frozen Aliquotting

For preserving sample quality and streamlining sample processing.


The CXT 353 Frozen Sample Aliquotter is a semi-automated bench-top instrument that can aliquot a wide range of frozen samples like tissue, feces, serum, plasma, whole blood, urine, and other biofluids. The CXT 353 can extract multiple frozen aliquots from a single sample, thus increasing utilization of  rare samples for critical studies. During the aliquotting process, both the parent sample and frozen aliquots are maintained below -80°C via LN2 chilling, effectively eliminating the freeze-thaw cycle and maintaining the integrity of samples.
