A 10 mL micropipette needs to measure up to 10,000 µL. That immediately rules out a 10 µL pipette, a 1,000 µL pipette and a bottle that merely holds 10 mL. For adjustable milliliter transfers, start with a documented 1–10 mL single-channel pipettor, then check its matching tips and calibration paperwork.
Two useful options to compare are the Eppendorf Research plus 3123000080 and BRAND Transferpette S D-10000, catalog number 705884. Both cover 1–10 mL, but the sensible choice depends on the tip system, servicing and purchasing arrangements you can support. The comparison below uses manufacturer documentation and exact product listings; it is not a hands-on performance ranking.
First, check what “10 mL” actually describes
- 1–10 mL adjustable pipettor: the instrument can be set within that stated range.
- 10 µL pipettor: its maximum volume is one thousandth of 10 mL. The unit symbol matters.
- 1,000 µL pipettor: its maximum is 1 mL, not 10 mL.
- 10 mL tip: a consumable that needs a compatible instrument.
- 10 mL graduated pipette: a different format used with an appropriate pipette aid. Do not confuse the aid or pump with a piston pipettor.
- 10 mL bottle or transfer dropper: capacity alone does not establish calibrated delivery of a selected volume.
Also distinguish an instrument’s range from its family’s range. A product family covering microliters through 10 mL contains several separate instruments. The part number in your cart must identify the large-volume version.
Two documented 10 mL pipettors to compare
| Instrument | Exact version | Range and setting increment | What to check before ordering |
|---|---|---|---|
| Eppendorf Research plus | 3123000080, single-channel, turquoise | 1–10 mL; 0.01 mL steps | Compatible turquoise epT.I.P.S., protection filters and calibration service |
| BRAND Transferpette S | 705884, D-10000, single-channel | 1,000–10,000 µL; 10 µL steps | BRAND 1–10 mL tips, performance certificate and service support |
The two increments are equivalent: 0.01 mL equals 10 µL. An increment describes the volume setting, not a promise that every delivery is within that amount of the target. The model identifiers and specifications are documented in Eppendorf’s Research plus range, its operating manual and the BRANDTECH specification sheet.
Eppendorf Research plus 3123000080: for an established Eppendorf tip system
This is the turquoise 1–10 mL Research plus, supplied with a sample bag of epT.I.P.S. The exact catalog number is particularly useful because visually similar Research plus models cover much smaller volumes. Sigma-Aldrich’s product listing identifies the manufacturer number as 3123000080 and the volume as 1–10 mL.
Consider it if your lab already sources the appropriate Eppendorf consumables and has a practical servicing route. Eppendorf’s catalog lists standard turquoise epT.I.P.S. 0.5–10 mL, 165 mm, as 0030000765. The longer 243 mm version has a different part number, so check both capacity and length. A tip’s wider stated range does not extend the pipettor below its own 1 mL minimum. See the manufacturer’s tip ordering information.
The manual documents protection filters for the 10 mL instrument and calibration under DIN EN ISO 8655. Include replacement filters and a calibration plan in the purchase, and ask what documentation accompanies the specific unit. Do not treat a product-page accuracy specification as a calibration report for the instrument you receive.
BRAND Transferpette S 705884: for a documented BRAND tip and service setup
Choose the D-10000, 705884 version. BRAND’s manufacturer store table identifies its 1,000–10,000 µL range and recommended 1,000–10,000 µL tip size. The S family includes smaller models, while Transferpette pro is a separate product line; the name alone is not enough to order correctly.
The S offers volume-change protection and an adjustment system called Easy Calibration. BRANDTECH’s specification sheet says the single-channel instruments are supplied with a performance certificate. Those are useful purchasing details, but they do not remove the need to check delivery performance in your own quality system.
Its main practical consideration is the tip supply. BRANDTECH identifies the 1–10 mL tip specifically for the 10 mL Transferpette and warns that tip compatibility can vary with instrument design and manufacturing date. Confirm the tip part number with the supplier rather than accepting a generic “universal” description. The manufacturer’s tip selection guidance also explains why changing tips can require a calibration adjustment.
Match the instrument to your normal working volume
Write down the volumes you actually need, including the smallest one. A 1–10 mL pipettor can cover 8 mL, but it is outside its specified range at 0.5 mL. If most work is near the low end, compare the error specification at that volume with a smaller instrument that also covers it. BRANDTECH’s selection guide explains the benefit of choosing a suitable smaller range rather than routinely using the bottom of a much larger one.
Consider the receiving vessel as well. A compatible tip must reach the liquid and fit the vessel opening without forcing it. If you mainly need one fixed volume, compare an appropriate fixed-volume instrument or volumetric pipette with your adjustable option before paying for flexibility you will not use.
Ask for calibration evidence you can use
Before buying, ask the supplier for the documentation included with that exact part number and the available calibration service. Useful questions are:
- Does the report identify the instrument and its serial number?
- Which volumes were checked, with which tip type, and on what date?
- Are measured results and applicable acceptance limits included?
- Does your work require an accredited calibration service or a particular report format?
- What will routine calibration, replacement tips and repairs cost?
These questions help distinguish a general certificate or marketing claim from evidence that meets your own requirements. Eppendorf’s manual describes calibration as a maintenance task; BRAND provides an operating manual and testing instructions for its instruments. Use the applicable documents and your organization’s procedures to set the inspection schedule. A calibration tool in the box does not establish the condition of a pipette indefinitely.
Tip fit, liquids and cleaning are separate checks
Buy the instrument and approved tip system together. Volume capacity, cone fit and sealing all matter; matching the color or the words “10 mL” is insufficient. Keep the tip model used for calibration in your records.
These are air-displacement instruments. If the liquid is unusually viscous, volatile or chemically aggressive, check the manufacturer’s compatibility and operating limitations before selecting the pipette. A different dispensing method may suit the task better. Do not infer chemical compatibility from a plastic housing or from a broad laboratory-use description.
Similarly, an autoclavable part is not a guarantee that a delivered instrument or tip is sterile. Follow the exact model’s cleaning instructions. Neither a calibration claim nor an ability to clean a component establishes suitability for clinical or diagnostic work.
Which one should you buy?
Start with the Research plus 3123000080 if the Eppendorf 10 mL tip and service system fits your workplace. Compare the Transferpette S 705884 if BRAND consumables and support are easier to maintain. Request a quote that includes tips and the calibration documentation you need, then compare the complete setup.
For either choice, the final check is simple: the ordered part number must specify 1–10 mL, the tips must be approved for it, and the calibration evidence must match your use. A longer shopping list does not improve that decision.
