Socorex StepperTM 411 Adjustable Repetitive Pipette
The Socorex StepperTM 411 Adjustable Repetitive Pipette is a high-precision laboratory instrument that enables fast and reliable multiple dosing with minimal effort. Thanks to the unique four-finger pressure function, the thumb is noticeably relieved, making the pipette ideal for prolonged use. Compared to other repeater pipettes, this model offers a clear volume display, a high degree of shock resistance and sophisticated corrosion protection, which ensures precise results in the long term. In laboratory situations in particular, where controlled and reproducible work is required, this device scores highly thanks to its versatile volume range of 10 to 5000 µl and up to 73 individual doses.
Precise and ergonomic dosing
The compact design and selected materials ensure long-lasting durability and safe handling. The four-finger mechanism is used precisely where repetitive movements in laboratory environments often lead to fatigue: in the wrist and thumb area. This special design distributes the necessary pressure over several fingers, which leads to significant relief.
In addition, the clear display of the volume allows different dispensing quantities to be set precisely. This makes the device ideal for applications that require fine gradations and microliter-precise repetitions, for example in sample preparation or the serialization of test series.
The color coding of the included positive displacement syringes is particularly advantageous, as it helps to quickly identify and assign the appropriate volume. The internal construction of these syringes minimizes the risk of contamination by being designed for alignment without complicated gaps. The stop or safety mechanism at the end of the pipetting process prevents uncontrolled liquid dispensing and makes it easier to change syringes or adapter parts.
- Four-finger dispensing lever for fatigue-free working
- Adjustment knob with clear volume display
- Three color-coded syringes for different volume ranges
- Shock-resistant materials and corrosion protection
- Repeatable doses up to 73 times
- Volume interval from 10 µl to 5000 µl
- Safety lock to prevent accidental dosing
The robust design and stable surfaces also ensure easy cleaning and maintenance. This reduces operating costs and ensures a long service life. An accompanying inspection certificate confirms the accuracy, which is a great advantage for quality audits and regular calibrations.
Certifications and standards
Socorex Isba S.A. attaches great importance to high quality standards. The pipettes generally meet the current requirements of the ISO standards for piston-operated pipettes and repeater pipettes, as they are designed for professional laboratories in research, medicine, pharmacy and industrial applications. Conformity with the relevant standards contributes to increased measurement reliability and reproducibility. In addition, the materials used support CE conformity in terms of durability and safety.
Examples of applications
- Microbiological tests: Precise dosing of culture media or bacterial suspensions in Petri dishes.
- Clinical diagnostics: Repeatable dispensing of reagents, for example for enzymatic tests or analytical procedures with several steps.
- Molecular biology: Precise sample preparation for PCR assays to ensure consistent conditions.
- Chemical analysis: Fast and reliable processing of standard solutions or buffers so that even the smallest volumes can be dosed precisely.
Typical uses include the precise pipetting of common reagents such as buffer solutions, enzymes, dyes or standardized calibration liquids, which are used in biotechnology, pharmaceutical and environmental analysis laboratories.
FAQs
How often should the pipette be calibrated?
It is advisable to check the pipette at least once a year or after a specified number of cycles. For particularly sensitive applications such as forensic analysis, more frequent calibration may be advisable.
Is the repeater pipette autoclavable?
The majority of the components are generally easy to clean. Certain parts can also be autoclaved when partially disassembled. It is advisable to strictly follow the manufacturer's instructions on autoclaving.
How does the syringe change work?
Thanks to the adapter and the color-coded syringes, changing the syringe is quick and easy. Simply remove the empty syringe and insert the appropriate plunger with the desired volume until the locking mechanism clicks into place.
Which liquids are compatible
The robust design and corrosion-resistant materials enable a wide range of applications: aqueous bases, low-concentration acids, organic solvents and buffer solutions are generally compatible without any problems. In the case of highly aggressive or viscous media, material compatibility should be checked on a case-by-case basis.
Conclusion
The repeater pipette presented here offers an ideal combination of precision, ergonomics and durability. In particular, multiple dispensing with precise volume control and the patented four-finger dispensing lever allow a high degree of convenience and safety in everyday laboratory work. The flexible volume range from 10 to 5000 µl, the clear color coding of the syringes and the reliable stop system underline the high quality standards. This makes this instrument an excellent choice for laboratories that rely on repeatability and user-friendliness without compromising on measurement accuracy.
