2.3Features

The epMotion 5070 is available with different features. All available features are described in this manual.

2.3.1Function

The epMotion 5070 is an automatic system for dispensing liquids using dispensing tools and ep.T.I.P.S. Motion pipette tips.

The epMotion 5070 dispenses liquids in the volume range 1 μL – 1 000 μL.

The dispensing tool aspirates liquid from source vessels and dispenses this liquid in destination vessels. The dispensing tool works according to the piston-stroke principle. For the epMotion, dispensing tools are available for 3 different volume ranges.

The epMotion features an optical sensor. The sensor checks:

Type and location of labware

Quantity and position of pipette tips in the rack

Filling level of vessels

You control the epMotion 5070 via the EasyCon control unit with the epBlue software.

You can use the epBlue software to define dispensing processes and compile them into an application. To do so, you select source vessels and destination vessels, define the procedure and define the transfer pattern.

2.3.2Cleanbench

The epMotion 5070f must only be operated in a Cleanbench. The function corresponds to a epMotion 5070 without a Cleanbench.

Additional information on your epMotion is available at: www.eppendorf.com/automation.

Fig. 5-2: Optical sensor principle

On the carrier, the optical sensor is located to the right of the tool holder.

The optical sensor records the intensity of the reflected light using a lateral infrared light source, semi-transparent mirror, fixed lens and the procedure in z-direction. Height z0 is defined as the point with the highest intensity which enables the detection of the level in a vessel or the presence of labware.

The optical sensor can detect horizontal, plane surfaces. The surface of the liquid must be at an angle of 90° ± 3° to the optical axis.

The surfaces of liquids can be strongly bent by the vessel geometry or the physical properties of the liquid or vessel. The optical sensor may not detect the level on strongly bent surfaces. If this is the case, the user must enter the liquid volume.

The optical sensor has a detection limit for vessel levels. The detection limit depends on the vessel geometry. Generally, levels of 3 mm or higher can be detected.

The following functions of the optical sensor can be activated:

Liquid detection

Determines the filling level for positions of labware, which has the Liquid detection option activated.

Tip detection

Checks to see if the pipette tips defined in the application are available. Determines the quantity and position of tips in the rack.

Works only with epT.I.P.S. Motion in TipHolders and Racks from Eppendorf.

Location detection

Detects the labware coding.

Checks to see if the labware on the epMotion worktable matches the labware on the epBlue worktable.

Information on setting the optical sensor, and a detailed description of all functions, can be found in the software operating manual.

5.3Tools

NOTICE! Damage to the gold contacts from handling.

The tool is damaged if the gold contacts on the tool become damaged or contaminated.

Do not touch the gold contacts.

The tool holder picks up a dispensing tool and puts it down again. The tool holder recognizes the tool from its gold contacts.

5.3.1Dispensing Tools

Multidispense: Piston travels to the home position in separate steps.

Pipette: Piston travels to the home position in one step.

The dispensing tools are piston-stroke pipettes that function according to the air cushion principle.

If the piston moves upward in the dispensing tool, liquid will be aspirated into the pipette tip. If the piston moves downward in the dispensing tool, liquid will be dispensed from the pipette tip. The pistons will be moved by a motor in the tool holder.

On eight-channel dispensing tools, all 8 channels move simultaneously.

6.1.2 Liquid aspiration up to the remaining volume

0,7 mm 1 mm

Fig. 6-2: Liquid aspiration up to the remaining volume with a constant immersion depth

The pipette tip is immersed 3 mm into the liquid before liquid aspiration. The pipette tip moves downward during liquid aspiration. The immersion depth of 3 mm remains constant while the liquid level decreases.

If the pipette tip reaches a distance of 1 mm to the base of the vessel, the pipette tip reduces its immersion depth to 0.7 mm. If the liquid level continues to sink, the pipette tip will not aspirate any additional liquid. The remaining volume remains in the vessel.

A remaining volume is present because the pipette tip has a minimum immersion depth in the liquid and a minimum distance to the base of the vessel. Under normal conditions, the remaining volume is calculated using a filling level of 1.7 mm.

The distance of the pipette tip to the base of the vessel can be changed in the software (refer to epMotion software operating manual).

If the liquid is aspirated from the remaining volume, the bend of the liquid level can lead to dispensing errors.

6.1.3Bottom tolerance

The bottom tolerance is the distance between the vessel base and the lower end of the pipette tip. The default setting for the bottom tolerance is 1 mm. For 30 mL and 100 mL reservoirs, the default setting for the bottom tolerance is 2.5 mm.

Decreasing the bottom tolerance also reduces the remaining volume.

1.Removing liquid above a pellet increases the bottom tolerance.

2.Do not decrease the bottom tolerance on uneven plates.

3.Check the set bottom tolerance when exchanging pipette tips, plates or vessels.
