Introduction
A fixed volume pipette delivers a constant predefined liquid volume. It is widely used in clinical and research laboratories. The system ensures dosing consistency. It solves variability in manual pipetting. By providing fixed measurement, it supports reliable laboratory workflows.
Standards
ISO 8655-1:2022-Piston-operated volumetric apparatus-Terminology, general requirements and user recommendations
ISO 8655-2-Piston-operated volumetric apparatus-Piston pipettes
ISO 8655-6:2022-Piston-operated volumetric apparatus-Gravimetric reference measurement procedure for the determination of volume
JJG 646-Metrological verification regulation for pipettes
Complies with the above standards, but is not limited to them.

FAQ
Q1: What is the fixed volume pipette mainly used for?
A: It is used to transfer a fixed volume of liquid accurately in chemistry, biology, clinical and pharmaceutical laboratories, such as dispensing reagents, standards and samples in routine assays. Fixed volume reduces operator error in repetitive dispensing tasks.
Q2: What standards does the pipette comply with?
A: The pipette follows applicable ISO standards for piston-operated volumetric apparatus, including accuracy and precision requirements, and relevant GB/T standards. Verification should follow the applicable standard method. Compliance documentation can be provided on request.
Q3: What is the warranty period for the pipette and key components?
A: The pipette carries a 12-month warranty covering the body and mechanism. Tips, seals and O-rings are excluded as consumables. Damage from improper handling, dropping or unauthorised repair is not covered.
Q4: Is the pipette difficult to operate?
A:Operation is simple and requires minimal training: attach the tip, aspirate and dispense with correct technique. Good pipetting practice, including pre-wetting and vertical immersion, improves accuracy. The manual explains correct use and maintenance.
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: Does the pipette require calibration or verification?
A: Pipettes should be verified gravimetrically against calibrated balances, typically every 3 to 6 months or per quality procedures. The pipette is factory calibrated before delivery. Optional calibration service can be arranged.
Q7: Are consumables or spare parts universal?
A: Pipette tips and seals are standard consumables available from our channel and compatible with common tip systems. No proprietary locked parts are required. Provide the model and serial number when ordering.
Q8: Can the pipette be customised?
A: Options include different volume ranges, tip systems, colours and calibration certificates. We confirm each option before order confirmation.
Q9: Is installation or setup required?
A: No installation is required; the pipette is ready to use with appropriate tips. Remote guidance is available for first-time use or technique training.
Q10: What liquids should not be pipetted with this pipette?
A: Highly viscous, volatile or corrosive liquids require appropriate technique and compatible tips. Avoid aspirating liquids that exceed the pipette volume or damage the seals. Follow laboratory safety regulations.
