EPPENDORF
Frequently asked questions
Common questions about EPPENDORF from 3G Electric.
What volume ranges are available in the Eppendorf single-channel pipettors supplied by 3G Electric?
The Eppendorf single-channel pipettors listed include fixed-volume and adjustable-volume models. Examples include a 500 µL fixed-volume pipettor (SKU 44C797, MPN 3124000113) with 0.2% accuracy, a 10 µL adjustable-volume pipettor (SKU 44C772) with 0.01 µL increments, and a 20 µL adjustable-volume pipettor (SKU 44C773) with 0.02 µL increments. Color coding is used: blue for 500 µL fixed, gray for 10 µL adjustable, and yellow for 20 µL adjustable. All listed models are autoclavable. For other volume ranges, check the full Eppendorf catalog or request a specific model through 3G Electric.
Are Eppendorf pipette tips from 3G Electric sterile or non-sterile?
Both sterile and non-sterile Eppendorf pipette tips are available. Sterile options include a 10 µL filtered tip in a preconfigured rack (SKU 26UX35) and a 5 mL individually wrapped tip without filter (SKU 26VC05). Non-sterile options include a 2.5 mL tip in a preconfigured rack of 480 (SKU 26UX51), a 2.5 mL tip in a bulk bag of 500 (SKU 26UX58), and a 2.5 mL individually wrapped tip (SKU 26VA87). All are made from biomedical-grade plastic. Selection depends on contamination-control requirements and workflow format.
What is the difference between Eppendorf pipette tips with and without filters?
Filtered Eppendorf pipette tips include an integrated filter, which is intended to reduce cross-contamination between samples and protect the pipettor from aerosol or liquid carryover. For example, SKU 26UX35 is a sterile 10 µL tip with a filter. Non-filtered tips, such as SKU 26UX51 (2.5 mL, non-sterile, racked) and SKU 26VC05 (5 mL, sterile, individually wrapped), are used where filter barriers are not required. The choice depends on the sensitivity of the application and the risk of sample-to-sample contamination.
Are Eppendorf pipettors from 3G Electric autoclavable?
Yes, the Eppendorf single-channel pipettors listed are autoclavable. This includes the 500 µL fixed-volume model (SKU 44C797), the 10 µL adjustable-volume model (SKU 44C772), and the 20 µL adjustable-volume model (SKU 44C773). Autoclavability allows sterilization between uses, which is relevant for workflows requiring contamination control. Always follow the manufacturer's recommended autoclaving conditions for temperature and cycle duration to avoid damage to the pipettor.
Which Eppendorf pipette tips are compatible with universal pipettes?
Several Eppendorf pipette tips supplied by 3G Electric are specified for universal pipette types. These include SKU 26UX35 (10 µL, sterile, filtered, preconfigured rack), SKU 26UX51 (2.5 mL, non-sterile, preconfigured rack of 480), and SKU 26UX58 (2.5 mL, non-sterile, bulk bag of 500). Other tips, such as SKU 26VA87 (2.5 mL, non-sterile, individually wrapped) and SKU 26VC05 (5 mL, sterile, individually wrapped), are designed for use with Eppendorf pipettors. Compatibility should be confirmed against the pipette model in use.
How can I identify the correct Eppendorf pipettor or tip for my application?
Identify the required volume range, whether fixed or adjustable volume is needed, channel count, sterility, filter presence, and packaging format. Eppendorf pipettors are color-coded by volume for quick identification. For tips, match the capacity (e.g., 10 µL, 2.5 mL, 5 mL) and compatibility (universal or Eppendorf pipettors). SKU and manufacturer part numbers, such as 3124000113 for the 500 µL fixed-volume pipettor, can be used to confirm specifications. 3G Electric can provide quotations based on these parameters.
