• Cat. No. 427 for 240 V, 50/60 Hz The Centra-CL2 accommodates a wide variety of rotors, including fixed angle and horizontal (swinging bucket). IEC AeroCarriers™ provide aerosol containment along with autoclaveability. The CL2 can handle up to 300 ml (801 rotor), and reach maximum speeds of up to 8500 rpm (841 fixed angle rotor) and 3900 rpm (236 horizontal rotor).
300mm in the event of a disruption. The user should therefore mark the clearance envelope boundary around the centrifuge, or laboratory management procedures should require that no person or any hazardous materials are within such a boundary while the centrifuge is operating.

Opening The Cover Once the red light over the STOP button is steadily illuminated (no longer flashing) pressing the COVER OPEN button on the control panel will release the interlock, allowing the cover to be opened. STOP/COVER OPEN Centra-CL2 Instruction Manual...
Tighten the nut with your fingers; do not use a tool. Rotors with or without a keyway can be used on the Centra-CL2 since there is no key on the shaft. Starting And Stopping A Run To start a run, use the ARROW buttons to set the desired run time (0 to 60 minutes) in the TIME display, and the desired rpm in the SPEED display.
1. Load four tubes. Positions 3, 6, 10, 13 or 2,5,9,12 or 1,4,8,11 2. Load six tubes. Positions 6,7,3,13,14,10 or 5,7,2,12,14,9 or 1,7,4,8,14,11 3. Load an odd number of tubes. Not recommended (unless a dummy tube is used for balance.) Centra-CL2 Instruction Manual...
4.2 Derating Table for Dense Samples The Speed and Force Table lists the Maximum speed for each rotor/ accessory combination in the Centra-CL2. IEC guarantees that the units can achieve these speeds when used at nominal voltage. These speeds are guaranteed only with samples whose specific gravity is not...
Compatible Processes For Decontamination WARNING: This chart describes the material compatibility of various sterilization methods. It does not specify the adequacy of sterilization. Refer to section 4.3 Chemical Resistance Table for material compatibility during centrifugation. Centra-CL2 Instruction Manual...
Store them open to the atmosphere, not in a plastic bag, so that any residual moisture will evaporate. The parts should face downward to avoid retaining moisture in the cavities. Centra-CL2 Instruction Manual...
1/4 of an inch long. Be sure to reinstall all parts removed. It is important to check the brushes periodically since damage to the motor can occur if the brush is allowed to wear down to the spring. Centra-CL2 Instruction Manual...
IEC part no. 40794 Cover Interlock Bypass The Centra-CL2 has an interlock bypass for easy sample retrieval in the event of a power failure. To bypass the safety interlock, unplug the centrifuge and pry off the plastic plug located on the bottom of the control panel. Pull downward on the cord to release the interlock.
Warranty IEC wants you to be satisfied with the quality of your Centra-CL2 centrifuge. We warrantee your IEC centrifuge for one year and IEC rotors for seven years. We will repair or replace a product that fails, within this period from the date of its delivery, due to defects in material and workmanship, and we will ship you the repaired product or its replacement at our expense.

Warning Messages and Error Codes The following Warning Messages and Error Codes can appear in the display of the Centra-CL2. A Warning Message indicates improper opeartion, and may be cleared by opening the lid, correcting the problem, and then using the centrifuge.
Slide the pin out. Interlock The IEC Centra-CL2 has a safety interlock which prevents the cover from being opened unless the rotor is turning 20 RPM or less. There is a switch in the interlock assembly which senses that the cover is closed and locked.
(such as wriststrap) when handling or servicing. Motor The IEC Centra-CL2 uses an AC series wound drive motor. The motor is not a singular replaceable component, as the base housing of the centrifuge serves as the motor housing. The motor is made up of an armature (includes bearings), field, brushes, brush holders, brush caps, brush leads, and a magnetic rotor.
Interlock PC Board The Interlock PCB in the IEC Centra-CL2 disables power to the interlock during rotation. This PC board is mounted below the motor. To sense rotation, it uses a Hall effect sensor to pickup pulses form a magnetic disk mounted on the motor shaft.
