6.2. Installation
5. Description of the centrifuge
The centrifuge SMC 6 is a table-top centrifuge with horizontal rotor designed for continuous operation. The
horizontal rotor contained in the standard delivery schedule and the tube holders can accommodate up to
6 specimen tubes. The special horizontal rotor facilitates a fast and simple specimen charge and completehorizontal separation.
A lid safety switch prevents the centrifuge from operating when the lid is open. The yellow “LATCH” indicator
at the front of the centrifuge lights up as soon as the lid has been correctly locked. In addition to the lid safetyswitch, the SMC 6 is equipped with a “0 rpm” lid locking system. This safety system keeps the lid closed at all
times (even in the event of a power failure) and ensures that the lid can be unlocked only when the rotor hascome to a standstill.

6• Position the centrifuge on a firm, vibration-free and flat surface.
• Maintain a safety zone around the centrifuge of at least 30 cm.
• During centrifuging, no person or dangerous substance must come within the safety zone.
• During operation, no contact must occur with other equipment or objects.
• Do not place vibration-sensitive objects or samples on the installation surface.
• There must be sufficient space above the installation surface to open the centrifuge lid.
• Ensure that there is adequate air circulation to prevent the samples and the centrifuge
from overheating.
• The installation location must always be well ventilated.
