Nominal volume
The maximum dispensing volume of a Combitip in conjunction with the selected dispensing device. The
term "nominal volume" comes from the ISO 8655 standard.

Positive displacement principle
The liquid comes into direct contact with the Combitip piston during aspiration and dispensing. Unlike with
a pipette, the liquid and piston are not separated by an air cushion. A small air bubble is visible at the piston
during dispensing.
R
Random error
Precision. Describes how large the deviations of several measurements are from each other, if the same
volume is measured several times.
Remaining stroke
Liquid reserve. The liquid which remains after all dispensing steps have been completed. You can discard
the liquid of the remaining stroke or reuse it.
Reverse stroke
After aspiration, the piston is moved into a defined position. Liquid is dispensed during this piston
movement. The reverse stroke is not a dispensing step.

Sterile
Sterile Eppendorf AG purity grade for consumables. Sterile meets the requirements for standard products,

2.3Features
Combitips advanced are disposable devices for aspirating and dispensing liquids according to the positive
displacement principle. Combitips advanced are used in Eppendorf dispensers (e.g., Multipettes/
Repeaters) and are made up of a cylinder and a piston. Combitips advanced in sizes 25 mL and 50 mL
require an Adapter advanced. Combitips advanced are available in various sizes, which are marked using a
color code.

2.6Evaluation criteria
The Combitips advanced can be used for the single dispensing of all chemicals which are included in the
following tables.
■■■Resistant
The chemical can be used.
■■Limited resistance and/or suitable for limited use
The chemical can be used for a limited period of time. Dispensing
must be performed soon after filling in order to ensure the tightness
of the Combitips advanced and to avoid damage to the dispenser.
Prolonged contact may negatively affect the error and the printing of
the Combitips advanced may become discolored and detached.
■Increased risk and/or increased wear
The chemical can only be used with utmost caution. Dispensing must
be performed immediately after filling in order to ensure the tightness
of the Combitips advanced and to avoid damage to the Combitips
advanced and to the dispenser. Prolonged contact may negatively
affect the error and the printing of the Combitips advanced may
become discolored or detached.

3.1Intended use
Combitips advanced are intended to be used with a Multipette/Repeater or a EDOS 5222 for dispensing
liquids in the 1 μL – 50 mL volume range. In-vivo applications (applications in or on the human body) are
not permitted. The Combitips advanced may only be used by specialized staff who have been adequately
trained. The user must carefully read the instructions for use and the operating manual of the dispenser
used and become familiar with how the device works.
3.2Warnings for intended use
WARNING! Damage to health due to infectious liquids and pathogenic germs.
When handling infectious liquids and pathogenic germs, observe the national regulations,
the biological security level of your laboratory, the material safety data sheets, and the
manufacturer's application notes.
Wear personal protective equipment.
Follow the instructions regarding hygiene, cleaning and decontamination.
For complete instructions regarding the handling of germs or biological material in risk
group II or higher, please refer to the "Laboratory Biosafety Manual" (source: World Health
Organization, current edition of the Laboratory Biosafety Manual).

WARNING! Damage to health due to toxic, radioactive or aggressive chemicals.
Wear personal protective equipment.
Observe the national regulations for handling these substances.
Observe the material safety data sheets and manufacturer's application notes.
NOTICE! Carry-over, contamination and incorrect dispensing results due to the incorrect
use of Combitips.
Combitips are intended for single use. Prolonged use can have a negative impact on
dispensing accuracy.
Only use Combitips once.
Do not use washed and/or autoclaved Combitips for dispensing.
NOTICE! Incorrect dispensing results due to evaporation.
If dispensing with an already filled Combitip is continued after a long waiting time, the next
dispensing step may have a slightly reduced dispensing volume due to evaporation!
If high trueness is required, this dispensing step should not be carried out.
12
Safety
Combitips advanced
English (EN)
WARNING! Personal injury and material damage from a bursting Combitip.
If stored for a long period of time, liquids can crystallize or solidify and thus block the outlet
opening. The Combitip advanced may burst during the process of dispensing.
Check the consistency of the liquid.
Dispense immediately after liquid aspiration.
®
4Operation
4.1Unpacking
To ensure maximum protection from carry-over, use Combitips advanced with Sterile and
Biopur grades of purity immediately after they have been removed from their packing.
3. Insert the Combitip into the dispenser.
Operation
Combitips advanced

4.2Assembling the Combitip advanced and Adapter advanced
Combitips advanced with a maximum volume of 0.1 mL – 10 mL can be used immediately. Combitips
advanced with a maximum volume of 25 mL and 50 mL can only be used with the corresponding Adapter
advanced. Adapter advanced and Combitips advanced have the same color code. The maximum volume is
also listed on the neck of the Adapter advanced.
NOTICE! Sensor damage due to damaged or worn adapter
Always put the adapter and Combitip together outside of the dispenser.
Do not used damaged or worn adapters.
Do not use adapters with damaged coding.
1. Place the adapter on the Combitip.
2. Tighten the adapter.
4.3Inserting the Combitip
NOTICE! Device damage due to incorrect handling of the inserted Combitip
Insert the Combitip straight into the dispenser from below.
Do not rotate the inserted Combitip.
Never grip the dispenser using the Combitip.
The Combitip is easier to insert if the ejector is held pressed down during insertion.
12
Operation
Combitips advanced
English (EN)
1. If the Combitip piston has been pushed out, push
it back into the cylinder of the Combitip.
2. Use force to push the Combitip into the opening
on the lower side of the dispenser until the
Combitip engages .

4.4Dispense liquid
The liquid dispensing angle should always be as steep as possible. A dispensing angle greater
than 45° can result in an incorrect dispensing volume during the final dispensing steps.
Additional information can be found in the operating manual of your dispenser.
