New Automated Blood SamplerUser defined sampling scheduleUses one fluid channel for sampling and infusionIntegrated fraction collectorIn-line sensors continually monitor dilutionAuto-retry and operator alert functionsThis new system automates the collection of blood samples from a range of species. By eliminating the need for labour-intensive manual withdrawals, the samplers can streamline pharmacokinetic studies. Exogenous or endogenous compound levels that could be effected by the stress of handling can be measured more accurately since the subjects is not even aware that a sample is being drawn. The sampler is compact (only 6 inches high) and can be set up above your existing cages. Each sampler employs four precision peristaltic pumps to withdraw blood from a freely-moving subject, it then stores the samples in an integrated refrigerated fraction collector, and replaces the withdrawn volumes with IV fluid. This all takes place using a single fluid channel which leaves you free to use an additional channel (when using a dual channel swivel) for drug infusion, blood pressure monitoring or other applications. You can control and monitor sampling schedules, volumes and withdrawal rates for up to 12 samplers from a single PC or Laptop using the standard serial port connection. The controlling PC can be located well away from the samplers, permitting remote control and further reducing exposure and stress to the subjects. An automatic calibration routine gives you the flexibility to choose catheters and tubing sets that work best for you. The sterile silicone tubing sets contain no valves, simplifying clean-up and replacement operations. Each sampler includes a fifth pump for IV drug administration using a second fluid channel. The system monitors proper movement of blood and IV fluid via two strategically located sensors, alerting the monitor to problems such as an occluded catheter and providing verification of successful operation in a log file generated after each sampling session.
