In the field of spectral analysis instruments, Persee has always centered on technological innovation and stable performance, providing reliable testing solutions for global users. Among its products, the T6 Series (T6U/T6V) stands as a classic benchmark, becoming an industry favorite due to its outstanding performance and market reputation; while the upgraded T400/T500 models have achieved comprehensive evolution based on this foundation. With more flexible design and smarter functions, they meet the diverse testing needs of the new era.
T6 Series: The Classic Cornerstone of Spectral Analysis
Since their launch, T6U and T6V have become “longtime friends” of laboratories, thanks to their “stable reliability and excellent cost-effectiveness”. Their core advantages stem from Pgeneral’s years of expertise in optical technology and modular design, which perfectly balance advanced functions with ease of use.
Performance Benchmark: Dual Guarantee of Accuracy and Stability
The T6 Series is equipped with an advanced double-beam monitoring ratio optical system, ensuring measurement accuracy from the source. Specifically, T6U covers a full wavelength range of 190~1100nm, with a wavelength accuracy of ±1nm and stray light controlled at ≤0.05%T—even capable of capturing subtle differences in low-concentration sample testing. T6V focuses on the visible light range of 325~1100nm, with a wavelength accuracy of ±2nm and stray light of ≤0.1%T, meeting the efficient needs of routine testing.
Stability is the “hallmark” of the T6 Series: The fully sealed monochromator, combined with silica-coated optical components, effectively isolates dust and humidity interference; the micro-step motor-driven grating eliminates the need for frequent calibration of positioning accuracy, enabling maintenance-free operation; the dual-light source combination of deuterium lamp and tungsten lamp (for T6U) ensures stable output across the full spectral range; and the environmentally friendly, corrosion-resistant housing allows the instrument to withstand harsh laboratory environments for long-term use.
Flexibility and Ease of Use: Adapting to Diverse Scenarios
The T6 Series handles tasks effortlessly, whether in scientific research laboratories or production quality control. Pre-programmed application cards support multiple functions such as DNA/protein analysis, kinetic testing, and quantitative measurement, allowing users to replace them flexibly as needed; it can be easily connected to computers and printers via the RS232 interface, enabling one-click data export and report generation.
User-friendly design is reflected in every detail: Fully automated functions—including automatic wavelength positioning, light source switching, and sample holder switching—reduce human operation errors; the built-in lamp life monitoring system displays the usage time of deuterium and tungsten lamps in real time, providing early warnings for replacement cycles; the fast scanning speed of 7000nm/min (wavelength-driven) greatly improves the efficiency of batch testing; and the simple operation interface and UV-Win software (including GLP-compliant version) lower the entry barrier for new users.
Market Verification: Classic Strength Proven by Reputation
With its core advantages of “low cost, high quality, and strong stability”, the T6 Series has been widely used in fields such as pharmaceuticals, environmental protection, food, and life sciences, becoming a long-term choice for tens of thousands of laboratories worldwide. User feedback shows that its average fault-free operation time far exceeds the industry average, and its maintenance cost is low—truly achieving “one-time investment, long-term reliability”.
T400/T500: Upgrading Classics to Redefine the Spectral Analysis Experience
Building on the mature technological foundation of the T6 Series, Pgeneral has launched the upgraded T400 (visible light) and T500 (UV-visible) models. While retaining the classic advantages, they have achieved three major breakthroughs—”more compact, smarter, and more flexible”—to adapt to the testing scenarios of the new era.
Enhanced Reliability: Optimizing Durability and Maintenance Costs
The T400/T500 inherit the T6 Series’ stable performance and further improve durability through structural innovations: The fully sealed optical system, with lenses covered by a silica protective film, significantly enhances dust and moisture resistance; the direct-drive grating motor replaces the traditional lead screw structure, completely eliminating the risk of mechanical wear and enabling lifelong maintenance-free operation; the washable dust filter keeps internal components clean at all times, extending the service life of core parts.
The exterior is made of high-strength corrosion-resistant materials, balancing aesthetics and durability. Even in scenarios involving frequent movement or outdoor testing (such as vehicle-mounted environments), the instruments maintain stable operation, with maintenance costs lower than those of the T6 Series.
Flexibility Innovation: Small Size, Great Capability
Addressing the needs of modern laboratories—”limited space and changing scenarios”—the T400/T500 adopt a compact design (470mm×400mm×210mm, weight 11kg), which can be easily carried by a single person and saves a lot of bench space. The elastically connected optical platform ensures no vibration damage during transportation, making the instruments suitable not only for fixed laboratory scenarios but also for mobile testing needs such as fieldwork and vehicle-mounted applications.
The open sample compartment supports flexible accessory replacement—from 8-cell sample holders to thermostatic cells and solid sample holders. No complex debugging is required to switch testing modes, adapting to diverse testing needs ranging from routine liquids to solids and high-temperature samples.
Intelligent Advancement: Comprehensive Expansion of Software and Functions
The T400/T500 are equipped with newly upgraded operating software, redefining the user experience with a “simple interface + powerful functions”: Four core modules (quantitative measurement, photometric measurement, spectral scanning, and system settings) cover most routine testing needs, supporting multiple fitting methods such as single-point calibration and dual-wavelength method—allowing new users to get started quickly.
For teaching and compliance scenarios, the instruments have built-in digital teaching systems and GLP compliance functions: VR animations intuitively demonstrate internal structures and working principles, making teaching more engaging; automatic operation log recording and hierarchical user permission management meet regulatory requirements such as GMP/21CFR Part 11, adapting to highly regulated fields like pharmaceuticals and clinical testing.
The fast scanning function (7000nm/min) triples the efficiency of wavelength positioning. Combined with one-click USB data export and instant archiving via external printers, it significantly shortens the testing cycle.
Application Scenarios: Full Coverage from Classics to Upgrades
- Scientific Research Field: T6U’s wide wavelength range and low stray light characteristics make it suitable for high-precision research such as DNA/protein quantification and material spectral analysis; T500 adds intelligent data analysis tools on this basis to accelerate scientific research data processing.
- Quality Control: The stable performance of T6V and T400 makes them ideal for routine quality control scenarios such as food additive testing and water heavy metal analysis, ensuring consistency in batch testing results.
- Teaching and Training: The VR function of T400/T500 makes them ideal teaching tools for university spectral analysis courses, helping students quickly understand instrument principles and operations.
- Mobile Testing: The compact design and anti-interference performance of T400/T500 enable their use in scenarios such as emergency environmental monitoring and rapid on-site sample screening.
From the classic inheritance of the T6 Series to the innovative upgrading of T400/T500, Pgeneral has always centered on user needs, integrating stable performance and technological innovation into every generation of products.
