Dispersion Tool S 25 N; Dispersion Tool S 25 Nk - IKA ULTRA-TURRAX T 25 basic Mode D'emploi

Generator:
The generator (dispersion head) consists of a rotor and a stator. These
parts can be unscrewed from the shaft. Note that rotors and stators form
matching pairs and must not be confused. Nine different dispersion heads
are available for various applications:
S 25 N - 8 G / ..- 10 G / ..- 10 G-VS / ..- 18 G / ..- 25 G / ..- 25 F
S 25 NK - 19 G
S 25 KV - 18 G / ..- 25 G / ..- 25 F
The dispersion tools you have ordered (e.g. S 25 NK - 19G) are always
supplied fully assembled.
Never run dispersion tools dry, as the gasket and bearings will be
destroyed if the tools are not cooled by the medium.

Dispersion tool S 25 N -

Overview (Fig. 5)
The bearing of the S 25 N - shaft is a friction bearing. This friction
bearing is made of PTFE. The shaft has a dispersion head added
whenit leaves the factory.
The dispersion tool can be disassembled for cleaning as described
below:
• Unscrew the rotor (9) from the shaft (13) using the gene-
rator and shaft key included in the tool set. The rotor is held
fast by means of the generator key and screwed off from
above by turning the shaft using the shaft key.
• Unscrew the stator (10) from the shaft (4) (left-hand
thread). Insert flat key into the front-end slot of the shaft
tube. By using the generator key the stator may now be scr-
ewed off in a clockwise direction.
• Pull the shaft (13) out of the shaft tube in a downward
direction. The individual parts threaded on the shaft (5, 6 and
20
S 25 KR - 18 G / ..- 25 G / ..- 25 F
S 25 KV - 25 G-IL / ..- 25 F-IL
7) may simply be pulled off.
• The slotted bearing (7) shall be replaced in the case of
wear.
Reassemble the dispersion tool in the reverse sequence. When
assembling ensure that the bearing bushing and the rotor are
correctly installed.

Dispersion tool S 25 NK -

Overview (Fig. 5)
The bearing of the S 25 NK shaft consists of a slide bearing and a ball bea-
ring. The slide bearing is made of PTFE. The shaft is provided with a rotor
when it leaves the factory.
The dispersion tool can be disassembled for cleaning as described below:
• Unscrew the rotor (7) from the shaft (2) using the generator and
shaft key included in the tool set. The rotor is held fast by means of
the generator key and screwed off from above by turning the shaft
using the shaft key.
