Introduction
A 12 channel adjustable volume pipette is a laboratory pipette with the twelve channels, used for the simultaneous dispensing of the same volume of the liquid into the twelve wells or the tubes, with the adjustable volume, and it is used in the biology, the clinical, the pharmaceutical, and the many other laboratories. The 12 channel adjustable volume pipette consists of twelve pipetting channels, each with the piston and the tip, a body with the volume adjustment mechanism, and a plunger, and it aspirates and dispenses the liquid into the twelve tips simultaneously, with the volume adjustable over a range, and it is used with the multi-channel tips; the 12 channel adjustable volume pipette is used for the dispensing into the 96-well and the 384-well plates, for the sample transfer, for the serial dilutions, for the immunoassays, for the cell culture, for the PCR setup, and for many other applications, and it is available in various volume ranges, with features such as the autoclavable parts and the tip ejector; the 12 channel adjustable volume pipette provides a rapid and a consistent dispensing, and it is an essential instrument for the high-throughput liquid handling. 12 channel adjustable volume pipettes are used in the biology laboratories, in the clinical laboratories, in the pharmaceutical industry, in the research, and for many other applications. With their twelve channels, 12 channel adjustable volume pipettes are essential for the multi-channel liquid handling.

FAQ
Q1: What testing scenarios is this instrument mainly applied to?
A: The 12-channel adjustable pipette is used in high-throughput molecular biology, drug screening, clinical diagnostics and immunology laboratories for simultaneous liquid transfer across all twelve wells of a microplate row. It supports ELISA reagent addition, PCR plate setup, cell-based assay plating, serial dilution and whole-plate sample processing where 8-channel pipettes would require two passes per row. The adjustable volume provides flexibility across multiple protocols with one instrument.
Q2: What standards does the instrument comply with?
A: The pipette complies with ISO 8655 piston-operated volumetric apparatus standards for accuracy and precision, and relevant GB/T standards for laboratory pipettes. Calibration certificates are provided. Users should follow the standard for periodic recalibration based on usage frequency.
Q3: What is the warranty period for the whole machine and key components?
A: The whole pipette is covered by a 12-month warranty. The piston assembly, body and volume mechanism are covered, while tips are consumables excluded from warranty. Damage from improper cleaning, autoclaving beyond rated cycles or dropping is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in proper multi-channel pipetting technique including aligned tip loading, consistent plunger speed and even immersion across all channels. We provide an operation manual. Consistent technique across all twelve channels is important to avoid well-to-well variation in assay results.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Calibration should be performed every 3-6 months for high-throughput use and every 6-12 months for moderate use, per ISO 8655 and internal quality procedures. Channel-to-channel uniformity should be checked during calibration, as 12-channel instruments are more sensitive to individual piston variation.
Q7: Are supporting consumables universal? What about the long-term procurement cost?
A: Pipette tips are standard and available from multiple suppliers. Filtered tips are recommended for contamination-sensitive work. Long-term consumable cost depends on throughput and can be optimized through bulk purchasing and tip reuse policies where appropriate.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes volume range, color coding and branding. Additional accessories such as calibration tools, stands and spare seals can be ordered separately. Minimum order quantities apply for custom versions.
Q9: Does the purchase include on-site installation and commissioning service?
A: No installation is required. The package includes the pipette, calibration tool and instruction manual. On-site calibration service is available at additional cost for high-throughput laboratories.
Q10: What types of samples are compatible with this equipment?
A: The pipette transfers aqueous solutions and compatible solvents within the volume range and material resistance. Highly viscous, volatile or corrosive liquids may require special technique or alternative pipette types. Users should verify channel alignment and tip sealing before critical assays to ensure uniform transfer across all twelve wells.
