Hirschmann laboratory instruments direct positive displacement pipette labopettor macro
The Hirschmann Laborgeräte labopettor macro positive displacement pipette is a versatile piston-operated pipette that is specifically tailored to the requirements of professional laboratory applications. Thanks to its direct displacement principle, it guarantees precise and repeatable results with a wide variety of liquids - even with highly viscous, highly gaseous or very dense media. Its five preset volumes and flexible setting levels make it particularly user-friendly, while the sophisticated design ensures safe handling.
Powerful piston stroke technology for precise dosing
This positive displacement pipette impresses with a specific piston stroke mechanism that reduces the residual volume in the device and therefore enables almost complete liquid displacement. This minimizes the risk of cross-contamination and ensures consistently high measurement accuracy. The device body is designed in such a way that pipetting substances with high vapor pressure - such as ethanol or acetone - and highly viscous media such as glycerine is reliable and effortless.
- Five fixed volumes:
- 50-250 µl (subdivision: 50 µl)
- 100-500 µl (subdivision: 100 µl)
- 0.5-2.5 ml (subdivision: 0.5 ml)
- 1.0-5.0 ml (subdivision: 1.0 ml)
- Easy switching between the volume levels
- Reusable tip that can be quickly replaced if required
- Individual serial number and weighing protocol for each pipette
- Sturdy construction and user-friendly design for everyday use
Each device is calibrated at the factory in accordance with relevant quality standards. Thanks to integrated setting options, experienced users can make additional fine adjustments if required. In addition, the instrument is designed to fully cover routine use in the range from 1 to 5,000 µl. The robust housing protects against damage in everyday laboratory use and supports a long service life.
Certifications and standards
The robust design and comprehensive quality tests ensure that the piston-operated pipette meets current standard requirements. In many laboratories, it is regularly tested in accordance with DIN EN ISO 8655 to guarantee consistently high precision. It is also typically labeled to meet European safety and health requirements.
Concrete application examples
- Pharmaceutical research: Ideal for precise dosing of active ingredients, for example when preparing samples with sensitive substances.
- Biotechnology laboratories: Enables consistent and clean pipetting processes, for example when handling cell cultures and enzymes.
- Quality control in the chemical industry: Reliable measurement of solvents, reagents or density media for analyses that require exact concentration.
- Research and development: Particularly useful in the development of new formulations where reproducible results are essential
The multiple use of the same tip allows costs to be reduced and resources to be conserved without sacrificing accuracy. This also makes the system particularly profitable for laboratories with high work volumes and changing result requirements.
FAQs
Is the device autoclavable
?
Parts of the device are usually removable and can be sterilized according to the manufacturer's instructions. However, the main body itself should not be autoclaved.
How often can the tip be reused?
The tip is designed for several hundred uses, provided it is cleaned regularly and no highly corrosive media are used.
What measures ensure consistent pipetting accuracy?
Regular maintenance and calibration, as well as following the recommended cleaning steps, will ensure that the device remains accurate throughout its lifetime.
Can the pipette also be used with aggressive chemicals?
It is designed for a wide range of solutions, including aggressive media. Nevertheless, users should check the compatibility of the materials with the respective chemicals before use.
Conclusion
Thanks to its direct displacement principle, this piston-operated pipette offers constant, media-independent precision and effectively reduces the risk of swelling effects due to residual wetting. The flexible volume range, the robust individual components and the rapid adaptation to different liquids make it a time and cost-efficient laboratory tool. This ensures accurate, reproducible and standard-compliant pipetting for a wide range of applications.
