Luozhong Technology UV3000S Cosmetics UV Sunscreen Tester

Simplify sun protection verification with high efficiency

Luozhong Technology UV3000S Cosmetics UV Sunscreen TesterIntegrating technology and software upgrades to achieve high-precision in vitro sun protection index (SPF) analysis. UV3000S adopts technology to accurately determine the in vitro SPF (sun protection factor) of cosmetics and sunscreen products, helping products obtain the "ultra-high protection (SPF 50+)" certification, and supporting HEVIS (high-energy visible light) sun protection efficacy testing. In response to the industry's demand for simplified product labeling and based on optimized in vitro testing methods to verify UV protection effectiveness, UV3000S strictly follows internationally recognized in vitro testing standards and in vivo spectrophotometric specifications to ensure reliable and compliant test results.

Efficient and precise

UV3000S Flash Testing Technology - Accelerating and Reducing Costs for New Product Launch

◆ Rapid detection: Instantaneous measurement of transmittance of 290-450nm ultraviolet band and 400-500nm high-energy blue light (HEV).

◆ Adopting Spectralon ® Integral sphere system, combined with optimized xenon flash, achieves ultra uniform diffuse illumination of samples

New high-performance diode array spectrometer, combined with fiber optic technology, system level optimization ensures ultra-low stray light interference, wavelength stability, and high repeatability between flashes.

advantage

◆ Newly reinforced structure ensures long-term stable operation

Adopting Labsphere flash technology significantly reduces testing time

◆ New menu driven software, low learning cost, in line with industry standards, customizable interface and report format, meeting diverse needs

◆ More comprehensive testing capabilities: Expand the detection range to 290-500nm UV visible light band, which can simultaneously determine the UV Sunscreen Factor (UVSPF) and High Energy Visible Light (HEVIS) protective efficacy for preventing pigmentation

◆ New calibration validation kit, paired with linear filter holder, improves calibration efficiency by over 75%

◆ Accurate reproduction of sample positioning: Manually operate the sample stage positioning system to ensure that the sample position is consistent before and after irradiation, achieving high repeatability testing

◆ New automated sample stage (optional), further optimizing the testing process

◆ Flexible and diverse testing solutions: equipped with 50mm, 75mm, and ISO standard 9-point sample testing templates to ensure high repeatability of the testing process and data reporting

Easy to operate

This instrument adopts menu driven software, which can gradually guide users to complete the industry standard testing process. The built-in report function automatically generates key data analysis and industry standard report formats. The report contains complete information such as date, time, operator, sample number, and testing parameters. Users can conveniently access reports through PC, print them directly, or export them to data processing software for in-depth analysis and review.

*Application software system

Developed based on NET Framework @ and compatible with Windows ® 11 operating system, providing a complete user experience for capturing, archiving, and calling all test data (including raw substrate data that may affect UVA protection factor (UVA-PF) due to substrate surface roughness), and supporting data export function. Integrated performance verification program - supports rapid on-site verification and retesting to ensure continuous acquisition of instrument performance.
