AELAB Manual Normal Adjustable Single-Channel Pipette – Precise Liquid Handling

The AELAB Manual Normal Adjustable Single-Channel Pipette (AE-MA Series) is designed for precise liquid handling across a broad working range from 0.1 µL to 10 mL. Eleven mechanically adjustable models cover micro-volume to milliliter-scale transfers, each calibrated with defined maximum permissible systematic and random errors at key test volumes.

Engineered for routine laboratory use, the AELAB AE-MA Series manual pipette supports accurate and reproducible dispensing in clinical diagnostics, pharmaceutical quality control, research laboratories, and industrial testing facilities. Fine volume increments and ergonomic control help standardize pipetting technique while maintaining ISO-style performance levels.

⚙️ Design & Construction

The AELAB Manual Normal Adjustable Single-Channel Pipette is a mechanical air-displacement pipette with a single liquid channel and interchangeable disposable tips. Each AE-MA model incorporates a robust piston-cylinder system, a calibrated volume adjustment mechanism, and a lightweight body designed for one-handed operation. The thumb-operated plunger and integrated tip ejector support comfortable repetitive pipetting, while the clearly readable volume indicator allows precise setting of the selected volume within the specified range for each model.

The body of the AE-MA Series pipette is optimized for chemical resistance and routine cleaning, providing stable performance when used with aqueous and low-to-medium viscosity laboratory liquids. The design maintains a consistent stroke length and plunger feel across the series, allowing operators to switch between AE-MA01 to AE-MA11 with minimal retraining and improved traceability of liquid handling steps.

🔬 Working Principle / Testing Method

The AELAB Manual Normal Adjustable Single-Channel Pipette operates on the air-displacement principle. When the plunger is pressed to the set point, the piston displaces a defined air volume inside the tip cone. Upon release, sample liquid is aspirated into the disposable tip, matching the calibrated volume selected on the AE-MA Series scale. A second plunger stroke dispenses the liquid into the target vessel, ensuring controlled delivery of the programmed volume.

For each AE-MA model, the maximum permissible systematic error (inaccuracy) and random error (imprecision) are specified at three test volumes covering the upper, mid, and lower portions of the working range. These values guide laboratories in establishing calibration and verification procedures and help ensure that volumetric transfer meets method-specific tolerances in quantitative assays, dilutions, and sample preparation workflows.

💡 Key Advantages

• Wide combined working range from 0.1µL to 10mL using eleven AE-MA models, enabling a single AELAB pipette family to cover micro-volume and bulk liquid handling.
• Fine volume increments down to 0.05µL for AE-MA01 and 0.1µL for AE-MA02, supporting precise pipetting in molecular biology, PCR setup, and trace analysis.
• Defined maximum permissible systematic and random error values for each test volume, simplifying ISO-style calibration and performance verification.
• Ergonomic mechanical design with thumb-operated plunger and integrated tip ejector for comfortable high-throughput pipetting sessions.
• Single-channel configuration optimized for accurate transfer of small volumes, minimizing cross-contamination risk with disposable tips.
• Consistent operating feel and control concept across AE-MA01–AE-MA11, supporting standardized training and streamlined laboratory SOPs.
• Mechanical construction with no power or electronics, providing reliable performance in benchtop, field, and teaching laboratories.

🔗 Connectivity & Integration

As a purely mechanical liquid handling device, the AELAB Manual Normal Adjustable Single-Channel Pipette requires no electrical power or electronic interfaces. This simplifies integration into any laboratory workflow, including laminar-flow cabinets, fume hoods, cold rooms, and bench-top sample preparation areas. Data related to volume settings, calibration results, and serial numbers can be recorded in LIMS or laboratory notebooks as part of GLP-compliant documentation. For applications that demand electronic tracking or automated volume programming, the AELAB pipette can be paired with external gravimetric calibration systems and quality control software but itself remains a robust, low-maintenance mechanical tool.

🧠 Model Insight

🧪 Testing Applications

The AELAB Manual Normal Adjustable Single-Channel Pipette is suitable for a wide spectrum of analytical and preparative tasks, including preparation of standards and reagents, serial dilutions, sample aliquoting, and buffer transfers. The micro-volume models (AE-MA01–AE-MA04) support molecular biology, genetics, PCR setup, and enzyme kinetics, while the mid-range AE-MA05–AE-MA09 models fit clinical chemistry, environmental monitoring, and routine quality control testing. High-volume AE-MA10 and AE-MA11 pipettes are appropriate for media preparation, reagent distribution, and bulk solution handling in microbiology and industrial laboratories.

Compliance & Quality Assurance

AELAB manufactures the AE-MA Series manual pipette under stringent quality control and aligns all performance tolerances with ISO-style volumetric standards for air-displacement pipettes. Technicians calibrate each model at multiple test volumes and list the maximum permissible systematic and random error values. These clearly defined limits allow laboratories to compare pipette performance directly with their method requirements.

Laboratories can implement regular gravimetric or photometric verification schedules and document results as part of GLP or ISO 17025 quality systems. Together with AELAB’s service and calibration support, the AELAB Manual Normal Adjustable Single-Channel Pipette provides a reliable, traceable platform for precise liquid handling.
