General information

The Eppendorf Combitube is an
aspirating aid for the Repeater
4780 / plus / pro / stream or
Xstream. Using the
Combitube, liquids can be
directly taken out of all original
bottles whose diameter does not
exceed 50 mm. The Combitube
can remain in the bottle and can
be sealed by inserting a
Combitip / Combitip plus into
its opening.

Application

– Shorten the tube, e. g. with

a scalpel, to the desired
length. The tube should not
touch the bottom of the
bottle (Fig. 1).

– Hang the Combitube into

the reagent bottle.

– Clamp the enclosed

Combitip plus 25 ml* into

firmly

the Repeater and
insert the tip into the
opening of the Combitube
(Fig. 2).

– Aspirate liquid by slowly

sliding the filling lever of the
Repeater up to the stop.

for organic solutions (e. g.
chloroform, ether)!

Cleaning the Combitube

from the liquid and hold
over a waste container (Fig.
