The medite COT 20 is a linear staining machine which because of its continuous
working principle can be adapted to the individual requirements of histology and
cytology laboratories.
The stainer has 23 troughs with a volume of 250 ml each. Corresponding to the
employed staining method, between station 2 and 17 running water can be used,
supplied by a central water connection. The instrument is constructed in such a way
that up to 4 slide holders can be placed in the start position. Additionally, two
separate removable solvent containers are integrated in the working plate, taking up
10 slide holders each. The slide holders are capable of 20 slides each.
The Tissue Stainer COT 20 is supplied with an instrument cover, reducing the fume
contamination and avoiding a pollution of the staining solvents. Additionally, there
are two covers made of stainless steel which can be put on the staining baths when
the instrument is out of use. The medite Tissue Stainer COT 20 is supplied with fume
extraction as standard equipment.
According to the staining time which can be regulated by means of a timer from 20
seconds to 10 minutes, the slide holders are transported and pass the baths. The set
time is always the same for every bath. Normally, a staining time of 2 minutes is
chosen. In order to keep the carryover of the solvents as low as possible, the COT
20 is equipped with a drain mechanism, adjustable at a timer from 3 to 60 seconds.
By using the agitation, i.e. the up and down movement of the slide holders in the
bath, the effectiveness of the solvents can be increased and the staining time may
be reduced. However, in order to avoid that sections of sensitive specimens detach
from the slides, it is recommended to work without agitation.
