Are the Multidrop Combi reagent dispensers compatible with Momentum Workflow Scheduling Software?

Yes, the Multidrop Combi reagent dispensers are compatible with the Momentum Software and can be integrated into automated workflow platforms. If you are planning to set up an automated workflow using the Momentum Software, you will also need a microplate mover such as the Orbitor RS2 Microplate Mover, Spinnaker Microplate Robot, or Spinnaker 3 Microplate Mover.

Do Multidrop Combi Reagent Dispensers (Cat. Nos. 58403xx and 58404xx) come with a laptop?

No, Multidrop Combi Reagent Dispensers are not sold with a laptop. This would need to be purchased separately. You can also use your own laptop or PC, as long as it meets the minimum PC requirements outlined in the Thermo Scientific FILLit Software for Multidrop Combi User Manual (pg 15).

When should I use the Versette Automated Liquid Handler vs. the Multidrop Combi Reagent Dispenser?

The Versette Automated Liquid Handler is the perfect solution for applications that require aspiration of liquid, plate transfers/reformatting, mixing, serial dilutions, and other common plate preparations performed using hand held pipettes in the lab.

The Multidrop Combi Reagent Dispenser should be used for fast bulk reagent dispensing and plate preparation.

I have an old spare valve which does not have any valve correction factor enclosed. Can I still use it?

Yes, old spare valves do not have this correction factor and the default value 0 is correct. If an old valve replaces the newer version, the correction factor needs to be set to value 0.

Do I need to recalibrate the instrument when a dispensing valve is changed?

No, you do not have to recalibrate the instrument, because the valve performance is so consistent. However you must apply the valve correction factor to the instrument through the FillIt software.

What is the orifice diameter (OD) of the dispensing valve?

The orifice (OD) is 100 μm.

Where can I see the Multidrop Combi nL internal software version number?

There are 2 places to find the internal software:
1) When the instrument is powered on, the version number appears at the top of the screen during the startup animation.
2) Device information under the Options menu also provides the internal serial number.

Can the Multidrop Combi nL reagent reservoir be autoclaved?

Yes, the reagent reservoir can be autoclaved.

What should I do if the liquid foams during dispensing with the Multidrop Combi nL?

Some liquids foam more easily than others. One option is to reduce the speed (that is, the pressure). There are five dispensing speeds available: 1 to 5.

Do particles in the reagent affect dispensing with the Multidop Combi nL?

Yes. It is recommended that you ensure that there are no particles greater than 40 μm in the reagent to avoid blockage of the dispensing valves. Filter all reagents, detergents, solutions and water before use to remove any solid particles present.

What liquid is recommended for washing the Multidrop Combi nL tubing?

It is recommended that you use distilled and filtered laboratorygrade water and/or a detergent solution, for example, filtered 1% Micro-90, followed by distilled and filtered laboratory-grade water.

Where can I see the Multidrop Combi internal software version number?

When the instrument is powered on, the version number only appears on the bottom of the screen during the startup animation.

Can the Multidrop Combi and Multidrop Combi nL priming vessel be autoclaved?

Yes, autoclaving conditions are as follows: 1 bar pressure at 121 degrees C for 20 minutes.

What is the material of the Multidrop Combi and Multidrop Combi nL priming vessel?

The Multidrop Combi and Multidrop Combi nL priming vessel is made of blue polypropylene (PP).

Do I need specific plate adapters for the Multidrop Combi or MD Combi nL?

No, the Multidrop Combi and Combi nL incorporate a fixed plate adapter and does not use any external plate adapters.
