Benchtop UV light weatherproof test chamber

Usage
LFZ-UV-S is suitable for accelerated aging tests by light and water exposure to evaluate the relative durability of non-metallic materials such as paints, coatings and plastics. It is especially suitable for observing the physical properties of particularly durable materials such as gloss reduction, fading, haze, strength reduction, chalking, cracking, blistering and embrittlement. Also suitable for the food, pharmaceutical, and cosmetic industries.

Application in the food/pharmaceutical industry
It can meet the light stability test requirements of ICH-Q1 B new drug substance and new preparation drug: Near-ultraviolet fluorescent lamp can emit light at 320~400 nm, and has a maximum energy emission at 350~370 nm; sample should Exposure to cold white light is not less than 1.2 × 106 Lux·hr, and near ultraviolet energy is not less than 200 w·hr, so that the stability of the drug and the preparation are directly compared.

Application in the cosmetics industry
It can meet the validation of cosmetics for UV isolation, and it is crucial to quickly evaluate the anti-aging properties of materials, screen or improve old and new formulations, and monitor product quality. Simple, easy to use and maintain.

Features:

• The outer casing adopts cold-rolled plate spraying process and the inner liner adopts SUS304 stainless steel material;
• 4.3 inch touch screen, menu-based operation interface, easy to understand, easy to observe and operate;
• Irradiance, temperature, humidity, rain cycle, etc. can be set and displayed intuitively;
• Multiple 20W UV lamps are used. Compared with other types of lamps, the quality is stable, the spectral power distribution will not be attenuated with the aging of the lamp, and the service life is up to 5000 hours.
• LFZ-UV-S provides a 3-hole sample spray device to meet the uniformity of sample spray on the sample holder;
• Manually adjust the radiation intensit  y by selecting an ultraviolet radiation meter;
• Self-control of the blackboard temperature through test set values ​​to meet user requirements for light, spray, temperature and other aging tests;
• Equipped with 4 70*150mm standard sample holders, the user can test samples in all directions to meet the placement of shaped samples;

As with other laboratory accelerated tests, LFZ-UV test results cannot be used instead of natural exposure to determine the actual endurance of the material. LFZ-UV products provide comparative test conditions, as UV light is the main cause of the decline in outdoor product durability. Illumination factor, coupled with the relatively stable spectral energy distribution of fluorescent tubes and low price, UV aging test chamber has become the most widely used weathering test machine in the world with its advantages of speed, convenience and economy. As a simple model, LFZ-UV is especially suitable for experiments with limited economic conditions.
