Introduction
An 8 channel adjustable volume pipette is a laboratory pipette with the eight channels, used for the simultaneous dispensing of the same volume of the liquid into the eight 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 8 channel adjustable volume pipette consists of eight 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 eight tips simultaneously, with the volume adjustable over a range, and it is used with the multi-channel tips; the 8 channel adjustable volume pipette is used for the dispensing into the 96-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 8 channel adjustable volume pipette provides a rapid and a consistent dispensing, and it is an essential instrument for the high-throughput liquid handling. 8 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 eight channels, 8 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 8-channel adjustable pipette is used in molecular biology, immunology, clinical diagnostics and pharmaceutical research laboratories for simultaneous liquid transfer across eight wells of a microplate. It supports ELISA plate coating, PCR setup, cell culture medium changes, serial dilutions and reagent addition in high-throughput workflows where single-channel pipetting would be too slow. The adjustable volume allows flexibility across different assay protocols with a single 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 with new instruments. Users should follow the standard for periodic recalibration based on usage.
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 adjustment mechanism are covered, while pipette tips are consumables excluded from warranty. Damage from improper cleaning, autoclaving beyond the rated cycle or dropping is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in proper pipetting technique including pre-wetting, consistent plunger speed and tip immersion depth. We provide an operation manual and calibration guidance. No professional certification is required, but consistent technique is important for accurate multi-channel 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 laboratories and every 6-12 months for moderate use, according to ISO 8655 and internal quality procedures. Routine performance checks with a calibrated balance are recommended between formal calibrations, especially after maintenance or repair.
Q7: Are supporting consumables universal? What about the long-term procurement cost?
A: Pipette tips are standard and available from multiple suppliers in filtered and unfiltered options. Using original or certified tips is recommended to ensure sealing and accuracy. Long-term consumable cost depends on throughput and can be managed through bulk purchasing.
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, tip ejector and instruction manual. On-site calibration service is available at additional cost for laboratories without in-house calibration capability.
Q10: What types of samples are compatible with this equipment?
A: The pipette transfers aqueous solutions and compatible organic solvents within the volume range and chemical resistance of the materials. Highly viscous, volatile or corrosive liquids may require special technique or alternative pipette types. Users should verify material compatibility and use filtered tips for contamination-sensitive applications.
