This instrument requires a stable power supply of AC 220V±10% and a vibration-free benchtop to maintain specified wavelength and photometric accuracy. Optical components are sealed against dust and moisture, but the instrument should be operated in a clean laboratory environment to prevent long-term drift.
- Warm-up Requirement: Allow the instrument to stabilize after power-on to achieve photometric drift ≤0.001Abs/h.
- Cuvette Compatibility: Use standard 10 mm, 20 mm, or 50 mm cuvettes in the sample chamber for all measurements.
- Environmental Sensitivity: Sealed optical design minimizes dust and moisture ingress, but avoid extreme temperature or humidity variations to preserve baseline flatness.
What is the photometric drift stability of the Atomfair-VS-826 for long-term kinetic measurements?
The Atomfair-VS-826 exhibits a photometric drift of ≤0.001 Abs/h at 500 nm after a warm-up period, ensuring stable data for extended kinetic runs. Combined with a baseline flatness of ±0.003 Abs and low stray light (≤0.5%T at 440 nm NaNO₂), this instrument maintains high precision over time without signal drift.
Can the Atomfair-VS-826 accommodate non-standard cuvette sizes or solid samples without additional accessories?
The large-capacity sample chamber is directly compatible with 10 mm, 20 mm, and 50 mm standard cuvettes, but for solid samples or non-standard cell dimensions, an optional solid sample holder and special cuvette rack are required. The instrument does not include these in the base configuration and they must be purchased separately.
What are the power and environmental requirements for operating the Atomfair-VS-826 in a laboratory?
The spectrophotometer requires an AC power supply of 220 V ±10% at 50/60 Hz. Its sealed dust-proof and moisture-proof optical housing protects core components in humid or dusty environments, and the absence of a mechanical transmission structure makes it resistant to vibration and interference, allowing stable operation on standard benchtops without special isolation.
The Atomfair-VS-826 Visible Spectrophotometer delivers a 320-1100nm wavelength range with a 4nm spectral bandwidth, achieving ±2nm wavelength accuracy and ≤0.5%T stray light, making it suitable for routine quantitative and qualitative analysis across chemical, pharmaceutical, and environmental labs. Its large sample chamber and multi-function software support photometric, quantitative, and spectral scanning modes, though the AC 220V power requirement and halogen lamp warm-up drift of ≤0.001Abs/h impose operational constraints.
Positive
- High optical precision and low stray light: With wavelength accuracy ±2nm, repeatability ≤1nm, and stray light ≤0.5%T at 440nm, the instrument ensures reliable photometric data for routine analysis, supported by a holographic diffraction grating and silicon photodiode detector.
- Versatile sample handling and measurement modes: The large sample chamber accepts 10/20/50mm cuvettes, and the instrument supports photometric, quantitative, spectral scanning, multi-wavelength, and peak-valley detection functions, enabling direct concentration reading and standard curve fitting without repeated dilution.
Trade-offs
- Requires stable AC 220V power supply: The instrument operates on AC 220V±10%, 50/60Hz, so laboratories with non-220V mains or unstable voltage will need a voltage regulator or converter, adding infrastructure requirements.
- Photometric drift after warm-up: Specified drift is ≤0.001Abs/h at 500nm after warm-up, meaning the instrument must be powered on and stabilized before precise measurements, which may slow workflow in high-throughput labs.
