1.0 Hardware Overview

The LabTec™ has been designed to automate batch-dispensing of liquids from the low milliliter
(0.5 mL) to liter range. The LabTec™ allows you to optimize the dispensing rate per aliquot as well as
the dispensing precision and accuracy, while monitoring pressure if a fi er is in use. A high pressure
alarm may be set to stop the pump when a user-defined value has been achieved. The LabTec™
can be used for either sterile or non-sterile dispensing applications as well as for aqueous and
nonaqueous batch dispensing.
In automated batch dispensing, three (3) important parameters, namely, dispensing rate, precision
and dispensing accuracy need to be considered. The LabTec™ has typical precision and accuracy
levels consistently in the 0.3% to 1.0% range; however the actual precision and accuracy levels are
somewhat dependent on the dispensing speed or pump rate.
In general, the higher the dispensing rate is, the poorer the dispensing precision and accuracy will
be. Conversely, the dispensing precision and accuracy generally will improve with lowering of the
pumping rate.
The two-channel Tandem™ 1081 peristaltic pump head can accommodate PharMed and
Platinum-cured Silicone pump tubing, sizes 13, 14, 16, 25, 17 & 18. If equipped with the ™ 1082
model, sizes 15, 24 & 35 can be accommodated. All pump tube sizes are factory calibrated, however,
the user can easily recalibrate any tube size with a single keystroke from the LabTec
Constant Rate mode.
The ™ pump head delivers fl w rates ranging from 0.03 mL / min. to 2200 mL / min. for each of the
two pump channels depending on motor rpm. Two pump heads can be mounted together to provide a
four-channel pumping capability, and drastic reduction in pulsation when two upper or lower
channels are combined into one with appropriate Y-type connectors.
Note: The LabTec™ usually is configured with a 600-rpm motor and one of the aforementioned
pump heads. However, if your dispensing needs require, the LabTec™ is available with piston
or magnetic gear pump heads and appropriate motors that work well for both aqueous and
non-aqueous solutions.
