Prior to sampling, unused blood is aspirated
from animal to inserted an air gap.
Sample blood is aspirated and sandwiched by
The blood is collected via by a fraction collector.
The unused blood is returned to the animal
Sampling parameters (kinds of animals, intervals, volume, administration conditions*,etc.) are set for each channel independently or collectively. Irregular sampling setting is
Each channel is controllable independently. Group of channles
are also controllable simultaneously by channel grouping.
Sampling history, status and end time for each channel can
Every sampling time, its status and administration time*
for each channel are recorded. These data can be exported
to other softwares.
→ GLP compliance
Even if the PC freezes or is shut down, the parameters are
stored in the sampling unit and blood sampling isn’t interrupted.
(The sampling unit is equipped with Start/Stop button.)
* For administration, a syringe pump,
two way swivel, etc. are required.
Any sampling interval or volume is programmable by users and this
makes irregular time setting possible. Timer function is also equipped.
Sample blood is sandwitched by air gaps. This prevents sample dilution
as minimum as possible and eliminates any cross contamination. For a
precise sampling, volume of catheter and tubing are taken account of.
Blood sampling from freely moving animals is possible. Optical senser
makes sampling volume control more precise than usual. The volume of catheter is measured and calibration with this volume is carried out automatically. At most 16 units of the DR-II can be controlled simultaneously
or independently by one PC (One DR-II carries out sampling from one catheter).
