Introduction
A fluorometer is an instrument used to measure the fluorescence of the samples, which is the light emitted by the fluorescent compounds after the excitation, and it is used in the biology, the chemistry, the environmental, the food, and the many other applications. The fluorometer excites the sample with the light at the excitation wavelength, such as from an LED or a laser, and measures the emitted fluorescence with a detector, providing the fluorescence intensity, which is related to the concentration of the fluorescent compound; the fluorometer consists of an excitation light source, the optical filters or the monochromators, a sample holder, a detector, and the electronics, and it is available as the benchtop, the handheld, and the field models; the fluorometer is used for the measurement of the chlorophyll in the water, for the measurement of the fluorescent dyes and the probes, for the analysis of the nucleic acids and the proteins, for the measurement of the turbidity by the nephelometry, for the research, for the monitoring, and for many other applications, and it is an essential instrument for the fluorescence measurement. Fluorometers are used in the biology laboratories, in the chemistry laboratories, in the environmental monitoring, in the food industry, and for many other applications. With their fluorescence measurement, fluorometers are essential for the sensitive analysis.

FAQ
Q1: What testing scenarios is this fluorometer mainly applied to?
A: The fluorometer is used in molecular biology, biochemistry, pharmaceutical research, environmental monitoring, food testing and quality control laboratories to measure fluorescence intensity of samples for quantitative analysis, detection and characterization. It supports nucleic acid quantification (Qubit-style assays), protein quantification, enzyme activity assays, cell viability measurements, environmental pollutant detection, food safety testing and routine fluorescence-based assays. The compact, user-friendly design provides fast, sensitive fluorescence measurement without the complexity of a full spectrophotometer, making it ideal for routine assays and high-throughput screening. It is essential for molecular biology, biochemistry and analytical laboratories requiring fast, sensitive fluorescence measurement for nucleic acid and protein quantification, enzyme assays, cell-based assays, environmental monitoring, food safety and quality control, where fluorescence-based detection provides high sensitivity and specificity for routine quantitative analysis in life science, pharmaceutical, environmental and food testing applications.
Q2: What standards does the fluorometer comply with?
A: The fluorometer supports methods referenced in relevant ISO, ASTM and GB/T standards for fluorescence-based assays. The hardware complies with IEC 61010 laboratory safety standards. Calibration should use certified fluorescence reference standards. Specific assays follow validated protocols and manufacturer instructions for reagents and measurement parameters.
Q3: What is the warranty period for the whole machine and key components?
A: The whole fluorometer is covered by a 12-month warranty. The light source, detector, optics and controller are covered, while lamps, filters, cuvettes and assay reagents are consumables excluded from warranty. Damage from improper use or unauthorized repair is excluded.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in fluorescence measurement and assay technique. We provide an operation manual and remote guidance. Proper assay setup, calibration, blank measurement and result calculation are important for accurate fluorescence quantification. Many models are designed for easy operation with pre-programmed assays.
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 with certified fluorescence standards recommended every 3-6 months. Routine verification with a reference standard before each use session for critical measurements. Lamp replacement per usage hours or when intensity drops. Optical surfaces cleaned periodically. Full performance verification annually.
Q7: Are supporting consumables universal?
A: Assay reagents, cuvettes, tubes and microplates are available from multiple suppliers, though compatibility with the instrument format should be verified. Lamps and filters may be model-specific. Long-term consumable cost depends on assay volume and reagent types.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes excitation/emission filter sets, sample format (cuvette, tube, microplate), automation level and software features. Additional filters, sample adapters and accessories can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the fluorometer and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged for laboratory setup projects. Remote guidance is provided.
Q10: What types of samples are compatible with this equipment?
A: The fluorometer measures fluorescence in liquid samples including nucleic acid solutions, protein solutions, enzyme assays, cell suspensions and environmental samples within the measurement range and sample format. Samples should be properly prepared with appropriate fluorescent dyes or labels. Highly turbid samples may cause scattering interference. Very high fluorescence may require dilution. Users should select appropriate excitation/emission filters for the fluorophore, perform proper blank and standard measurements, account for photobleaching and inner filter effects, use matched cuvettes or appropriate tubes/plates, calibrate regularly, and follow assay protocols for accurate, reproducible fluorescence quantification.
