Commissioning

Attention has to be paid to the operating instructions of the individual components: stirrer RE 162 P4 analog and RE 162 P7 ana-
log respectively, and if required, the ULTRA-TURRAX T 25.
At first the filled reactor vessel is put into the container support in the instrument base. Then reactor vessel and hoses for tem-
pering liquid are connected. For this the quick-release couplings (plug nipple) with the in- and outlet hoses of the thermostat are
connected. The inlet is plugged to the bottom quick-release coupling and the outlet to the top quick-release coupling. The quick-
release couplings are self-sealing on both sides so that no tempering liquid can leak out.
The IKA-laboratory reactor LR.2000 V is designed for operations under vacuum or atmospheric pressure. The vacuum pump is
connected laterally at the left-hand side of the telescopic stand (see fig. 2).
The attained vacuum can be displayed by means of the vacuum gauge LR 2000.30 or by means of the IKA-vacuum controller
VC 2. All further installation parts such as dispersing tool, temperature sensor, flow breaker and ground-glass joints for the reac-
tor cover are sealed with PTFE-sleeves or O-rings.

Description

The IKA-laboratory reactor system has a modular construction. It consists essentially of the following construction groups (see
fig. 1).

Device base, telescopic stand

Vibration insulating plates are fitted to the bottom side of the instrument base: In the centre there are thermally insulated con-
tainer supports for fixing the reactor vessel. The telescopic stand is fitted at the rear. The protective gas spring, built into the
telescopic stand, allows for an easy lifting and lowering of the complete reactor. The reactor can be fixed at any given height by
means of a clamping device. At the rear of the stand column there is a multiple cable channel which houses the connecting
cable of the stirrer drive. The multiple cable channel can also take up the connecting cable of the ULTRA-TURRAX and the tem-
perature measuring instrument.

Stirring motor carrier, stirring shaft bearing

The stirrer carrier is clamped to the telescopic stand column. At its late-
ral side a bracket is fitted for the following connections:
- vacuum connection with stop cock
- vacuum gauge or vacuum controller
- aerating valve
- vacuum hose leading to the reactor cover
- threaded bore holes for stand rods
For depositing the ULTRA-TURRAX-drive, a bracket with spigot and a
stand rod is laterally fitted to the right-hand side. The stirring shaft bea-
ring is firmly fitted into the front bearing eye of the stirrer carrier. The
stirring shaft which is ball bearing supported and vacuum tight, is
connected firmly to the stirrer drive by means of a coupling flange. The
stirring shaft with covered ball bearings is precisely supported and sea-
led with radial shaft sealing rings with PTFE-sealing lips for vacuum ope-
ration. In order to keep the unavoidable abrasion of the stirring shaft cau-
sed by its running-in, away from the product, a protective ring is pushed
from below onto the stirring shaft. The anchor stirrer with teflon wipers
is also plugged from below into the stirring shaft. The rotary motion is
transferred to the anchor stirrer by means of a square bar, and is axially
fixed with a circlip.
