Introduction

Cole-Parmer series of benchtop multipurpose centrifuge (MPR16 refrigerated models 17406-20 and -25; MP16 ambient models 17406-50 and -55) offers rugged construction without sacrificing reliable performance. Extra-thick stainless steel chamber and zinc-coated alloy and steel frame increase durability for inorganic separations requiring strong solvents. Industrial-grade inverter drive (VFD) and brushless motor provide a long service life. User-accessible service sections allow onsite maintenance.

Refrigerated models feature a highly accurate PID controller which allows better overall temperature control, achieving the desired set temperature. In addition, the large, efficient CFC-free compressor uses less power and lasts longer.

LED displays show temperature, rpm, and time. Programmable memory supports 10 programs including acceleration and deceleration rates, allowing you to quickly perform routine tasks.

The included fixed-angle rotor (model 17406-09) accommodates eight 50-mL tubes—ideal for civil, environmental, and water supply engineering applications. Increase versatility by using optional rotors; call for details.

Before Operation

If the centrifuge has been in operation for some time, over an hour, at the same temperature, then equilibration is not necessary. However, if the centrifuge has just been turned on then we recommend the following for the best and most accurate results.

Below ambient or 18°C (4 to 18°C / 39 to 64°F) – Refrigerated Models Only

Turn on the unit. Select your temperature, make sure the rotor is in position and firmly fixed. Close the lid. Wait at least 20 minutes.

Whilst waiting place your samples, with tubes in refrigerated unit at the desired temperature.

After your set temperature has been reached, use the precondition mode by pressing down the Function button and Start/Stop button together. Two dots will appear on the display showing that precondition mode has been activated.

Precondition mode runs the centrifuge at half programmed speed to ensure full mixing of the chamber air and therefore equilibrates all areas of the rotor and parts for maximum efficiency.

Once this has finished, lift the lid and load samples in position. See page 9 for correct loading procedures.

How to Operate the Centrifuge

Load samples, fit lid (if applicable). Set Speed or RCF x g, then designated time.

Close the centrifuge lid. Press down firmly on both left and right sides.

Press Start button (bottom left), the motor will now accelerate to the designated setting.

When time has counted down (time display right), the rotor will decelerate (brake).

According to your programmed setting (9 being the fastest), the rotor will stop and “OpEn” will appear on the display.

Press Lid open button and retrieve your samples.

You can stop the run at any time by pressing the Start/Stop button.

How to Use the Pulse (short run) Feature

This method allows very short runs mainly for “pelleting” purposes.

Set your desired speed or RCF x g. Time is not relevant.

Load your samples. Fit lid (If applicable).

Press Pulse button (bottom right) keep held down. You will see the Time display counting up in seconds. As long as you keep the button held down, the time will increase.

On releasing the Pulse button, the centrifuge will brake.

Press Lid open button when “OPEN” appears on the display and retrieve your samples.

CAUTION!

Follow all safety instructions on previous pages. Always load samples evenly.

Troubleshooting

Mechanical Emergency Door Release

During a power failure, you will not be able to open the centrifuge lid with the regular electric lid release. A mechanical override is provided to allow sample recovery in the case of an emergency. However, this should be used only in emergencies and after the rotor has come to a complete stop

WARNING!

The rotor can still be spinning at high speed. If touched, it can cause serious injuries. Always wait until the rotor has come to a complete stop without braking. The brake does not work when there is no current. The braking process lasts much longer than usual.

Proceed as follows:

1. Make sure the rotor has stopped (view port in the lid).

WARNING!

Never use your hands or other tools to brake the rotor.

2. Pull out the power supply plug.

3. On the bottom of the housing is one black plastic plug which you can pry out of the side plate with a screwdriver. It is located below the front side of the centrifuge. It is reachable with a screwdriver. Pull the release cord attached to it to trigger the mechanical door release. The door will open and the samples can be removed. Open the front door.
