Hirschmann laboratory devices labopette®, fix, single-channel pipette
Short introduction
The fixed single-channel pipette is particularly suitable for precise and repeatable pipetting procedures in laboratory environments where constant volumes are required. Compared to other commercially available devices, it impresses with its exceptionally ergonomic design, high measuring accuracy and noticeably reduced force required for pipetting. This pipette offers an excellent combination of ease of use and reliable performance, especially for long-term series work.
Robust construction and ergonomic shape
Designed for maximum durability, the device withstands daily use and delivers consistently high pipetting quality. A special finger grip enables safe handling so that both right- and left-handed users benefit from a more relaxed grip position. In addition, an integrated tension spring mechanism significantly reduces the force required compared to conventional pipettes. This prevents signs of fatigue, which increases work efficiency in the laboratory.
The clear separation of the pipetting button and tip ejector is particularly practical, preventing unintentional ejection of the pipette tip. The outer housing insulation also prevents hand heat from penetrating the inside of the device, ensuring that measurements remain stable and reproducible even during prolonged use. Thanks to special materials, the entire model can be steam sterilized up to 121°C without the need for disassembly. This simplifies the cleaning process and reduces the risk of cross-contamination in microbiological or molecular biological applications.
Technical features at a glance
- Fixed volume setting for consistent precision
- Significantly reduced actuation force thanks to innovative tension spring mechanism
- Simple calibration for fine adjustment if required
- Completely autoclavable up to 121°C without disassembly
- Tip ejector separate from pipetting button
- With certificate of conformity and individual serial number
- CE marking in accordance with IVD 98/79 EC
In addition, the device offers R (accuracy) values between 2.5% and 0.6% for a wide range of volumes, depending on the version selected. At the same time, the relative standard deviation (CV) is between 1.5% and 0.3%. This helps users to ensure precise, reproducible and convenient pipetting for applications in research, quality control or clinical laboratory environments.
Depending on the volume range, the housing is color-coded to enable quick differentiation between different pipettes within a pipette set. Transparent tips are used for small volumes up to 10 µl, while yellow, blue or clear color coding is used for higher volumes. The matching tips range from 0.2 µl up to 10,000 µl, providing broad compatibility for numerous application requirements.
Certifications and standards
This pipette fulfills all requirements according to CE IVD 98/79 EC and is delivered with a certificate of conformity. In addition, each unit is given its own serial number and a calibration certificate. The device can be recalibrated if necessary in order to permanently meet the strict quality guidelines in professional laboratories. It therefore provides a reliable basis for precise measurements in DIN and ISO-certified facilities.
Typical areas of application
In microbiology laboratories, for example, cell culture media or bacterial cultures can be precisely dosed to ensure consistent growth conditions. In biochemical research, precise handling of reagents and buffers is crucial, for example when pipetting very small sample volumes for PCR assays with Taq polymerase. In clinical diagnostics, the pipette also supports the preparation of samples with consistent volumes, ensuring the reproducibility of tests such as blood serum analyses. In pharmaceutical laboratories, it can also be used for precise dosing tasks, for example when preparing test solutions.
FAQs
How often should the pipette be calibrated?
Regular calibration (e.g. every six to twelve months) is recommended. However, the exact frequency depends on the specific requirements of the laboratory and the quality guidelines to which you are subject.
Can all components be sterilized?
Yes. The device can be fully steam sterilized up to 121°C without having to be dismantled. This facilitates both cleaning and decontamination after sensitive applications.
How do I recognize the right tip for my selected volume?
Color coding on the pipette shaft and on the tip packaging helps with quick identification. In addition, the manufacturer's information on the tip packaging and the pipette itself provides information about the appropriate volume ranges.
Is there a risk of accidental tip ejection?
No. The tip ejection mechanism is separate from the actual pipetting button, which prevents unintentional ejection during sample pick-up. The tip is only released when the eject button is pressed specifically.
What are the advantages of the low grip load?
The integrated tension spring mechanism puts less strain on the hand and wrist. This allows you to work in the lab for longer periods of time without tension or strain.
Conclusion
The low force required, the option of complete steam sterilization and the precise volume setting make this model an ideal tool for professional use. Even with high demands in research and routine analysis, pipetting is possible with minimal physical strain. Thanks to the stable design, the clearly structured tip ejection and the easily accessible calibration options, consistent, reliable measurement results can be achieved over the long term - a plus point for any laboratory that values precision and ergonomics.
