PHOENIX Instrument Variable Piston Pipette LHP3 Series
The PHOENIX Instrument variable piston pipette LHP3 series is ideal for precise and reliable volume measurements in a wide range of laboratory applications. Accurate pipetting of critical reagents or samples is particularly important in research facilities, pharmaceutical companies and biotechnology. The large volume range and ergonomic design make this model an attractive choice for laboratories that require high flexibility and efficient working. At the same time, it impresses with its robust workmanship and long-lasting precision, making it suitable for both routine analyses and demanding test series, depending on requirements.
Comfortable and reliable handling
Thanks to its lightweight design and high UV resistance, the piston-operated pipette is also suitable for intensive use in different environments. Their low weight and the minimized effort required for operation prevent fatigue, which is particularly advantageous for many pipetting processes. In addition, the models can be hygienically cleaned and kept sterile thanks to their fully autoclavable design (at 121 °C). The pipette has an intuitive volume setting that can be adjusted using a rotary mechanism and locked if required. This prevents accidental adjustment of the set volume.
The following features make working with this device particularly user-friendly:
- Ergonomic design for comfortable pipetting
- Low weight for comfortable working
- Fully autoclavable at 121 °C for optimum sterility
- UV-resistant plastic for a long service life
- Color coding for volume marking and easy identification
- Simple volume adjustment with secure locking
- Calibration by the user for quick adjustment
All devices in this range comply with the strict requirements of ISO8655 and DIN12650 and therefore offer safety in terms of precision and reliability. As they are also suitable for calibration by the user, it is possible to react very quickly to different application requirements - a valuable feature for laboratories with varying pipetting volumes and high quality standards.
Technical highlights
The variable pipetting device covers an extensive volume range from 0.1 µl to 10 ml. Typical models range from 0.1-2.5 µl, 0.5-10 µl up to 2,000-10,000 µl, for example. Tests are carried out in the lower, medium and upper volume ranges in order to reliably guarantee accuracy and precision. The key characteristics include
- Accuracy in the per mille to lower percentage range, optionally 0.03% to 2.x% depending on the model
- Precision from just 0.02% to around 1.x%, depending on the volume range
- Fine graduation from 0.002 µl (depending on model)
The pipettes therefore meet a wide range of requirements that are particularly relevant in laboratories with high demands on reproducibility and measurement accuracy.
Where appropriate, the pipette can be used for applications in molecular biology for handling sensitive enzymes, buffers or reagents. They are also reliable for serological tests, cell culture, protein research and pipetting DNA and RNA samples.
Certifications and standards
The models are compliant with the applicable ISO8655 and DIN12650 standards, which underpins the high quality of the liquid handling equipment. In addition, these certifications help laboratories to comply with internal and legal requirements. Thanks to their full autoclavability, the pipettes also meet the hygiene requirements of many pharmaceutical and medical facilities.
Application examples
- Dosing of microliter-precise reagents in cell culture, for example for precise media additions.
- Handling sensitive enzyme solutions in molecular biology processes, for example in PCR.
- Pipetting DNA or RNA samples, where extremely small deviations could have a major impact on the results.
- Measuring larger volumes in biochemistry to reliably adjust the concentration of proteins.
Thanks to its robust design, it can also be used extensively in QC (quality control) laboratories and analytical areas without repeated sterilization processes impairing its function.
FAQs
Can I autoclave the pipette several times without affecting the quality?
Yes, the device is designed to be sterilized multiple times at 121 °C. A correct autoclaving process and drying will further extend its lifespan.
How can the volume setting be protected against unintentional changes?
A locking function prevents unintentional adjustment. Once the desired volume has been set, it is reliably fixed by a mechanism.
What are the advantages of UV resistance?
The plastic used also withstands UV light, which enables disinfection under UV radiation. The device therefore remains resistant and reliable for a long time.
Do calibrations need to be carried out regularly?
Regular checks are recommended to ensure precision. Routine adjustment is particularly useful for frequent use or very sensitive applications.
Conclusion
Thanks to its wide range of models and user-friendly design, this modern piston-operated pipette enables reliable and reproducible liquid handling performance in any laboratory environment. The large volume range, autoclavability and ergonomics ensure comfortable working and reliable measurement results. Accuracy, precision and certification according to ISO8655 and DIN12650 meet the highest demands, while the calibration option increases user flexibility. This ensures efficient liquid management that serves a wide range of laboratory tasks and is ideal for both routine and specialized work methods.
