Automated Blood Sampler - Instech

Automated Blood Sampler

Instech's ABS2™ automates the collection of blood samples from laboratory animals including mice, rats and large animals. By eliminating labor-intensive manual withdrawals it can substantially increase the throughput of pharmacokinetics research groups. It can also reduce the stress on animals caused by handling and venipuncture. 

 

The sampler withdraws blood from a tethered freely-moving animal according to your programmed schedule, stores the samples in an integrated refrigerated fraction collector, and replaces the withdrawn volumes with IV fluid. You control and monitor sampling schedules, volumes and withdrawal rates for up to twelve animals from a central computer.

Unique advantages of the Instech blood sampling system include:

  • Undiluted samples, verified by in-line sensors
  • A short collection path, to minimize mixing and collection times 
  • Less than 5 µL of blood wasted per sample, to minimize hemodilution 
  • The flexibility to work with a range of species, from mice and rats to large animals

The ABS2, Instech's second-generation autosampler, builds on the proven foundation of a series of precision peristaltic pumps to move blood and IV fluids directly to their destinations. The fraction collector has been redesigned from the ground up for additional features and high reliability. 

The ABS2 not only works with refrigerated vials (such as the Greiner MiniCollect® tubes), but also can deposit 10-25µL microsamples directly onto dried blood spot paper.

Instech has a version of the ABS2 that is optimized for use in PET imaging studies.
