1.1 Description
The Liquid Handling Station can be combined with sample changers
equipped with a robotic arm. Depending on the swing direction, either
the left-handed (6.2841.120) or the right-handed (6.2841.130) version of
the Liquid Handling Station is used.
The Liquid Handling Station consists of two function units:
Rinsing unit
The rinsing unit is equipped with a two-pipe system.
The interior pipe is for rinsing the sample tube.
The outer pipe is for the disposing of liquids and collecting the overflow
from the interior tube.
Dilution unit
The dilution unit is used for the fully automated production of diluted sol-
utions.
The Liquid Handling Station must be reconfigured for the sample dilution
function. In order to obtain a homogeneous dilution, it is important that
the concentrate be mixed with the dilution medium. A homogeneous dilu-
tion is achieved by installing the magnetic stirrer (2.741.0010) in the Liq-
uid Handling Station.
