Ductless Fume Hoods and Powder Stations   TOPAIR Systems manufactures ductless fume hoods and POWDER STATIONS to provide protection to both laboratory personnel and the environment from toxic fumes, gases, and particulate It has a powerful fan, which pulls the air through the hood and away from the operator’s breathing area while they work within the hood. Various filter can be used depending on the chemical vapors/and or particulates that are generated (such as HEPA filters or activated carbon). Applications : laboratory, chemical, manufacturing, pharmaceutical, commercial, and industrial. The advantages of the Duckless Ductless hoods are Green these hoods filter take out chemicals fumes and recycle it back to the laboratory as clean air, providing energy savings, personnel and environmental protection cost efficient you do not have to deal with complicated ducting systems mobility- ductless hoods are independent systems which do not require connection to extraction systems.  Topair Systems produces laboratory fume hoods in a wide range of sizes and configurations, that gives our customer all the flexibility
	Laminar Flow Clean Benches TopAir manufactures a wide range of Laminar flow clean benches in vertical and horizontal configurations for creating a class 10 (ISO 4) environment. Our vertical and horizontal benches are available in various sizes including a standard size and custom made. They can also be found in a range of materials. Applications: pharmaceutical industry, food industry, R&D Laboratories, hospitals, manufacturing facilities. The vertical/horizontal is best recommended for use in a clean area. It doesn’t provide protection for the worker. It gives ISO 4 in the work area using HEPA (High Efficiency Particulate Air) filter which removes particles from the air. The HEPA filter can trap 99.99% of particles that are less than 0.3 micron in size and help to meet the cleanliness requirements.

	UV - PCR CABINET Polymerase chain reaction (PCR) is a scientific technique in molecular biology to amplify a single or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. PCR is now a common and often indispensable technique used in medical and biological research labs THAT ARE working with DNA and RNA Because of the high copy number generated during PCR, it is essential to prevent possible contamination of the PCR reaction. The PCR process Prevent cross-contamination inside the working chamber at the end of the procedure, the operator will close the front window and the UV automatically will start. When the cycle has been completed the timer will automatically start the operational-mode (fl putrescent lights). . When the set time expires, the UV light automatically switches off in preparation for the next experiment. Our TopAir’ PCR models combines ergonomic design and premium materials to create the highest quality components. The dependable filtration system provides complete protection from contamination. The cutting-edge EBM motor fan provides long term reliability and ensures the lowest possible noise levels. Two styles are available: standard UV PCR and HEPA/UV PCR systems.  Prime features of TopAir’s powder stations include:  • Double UV sterilization system, in the PCR cabinet and in the filtration hall . • Double-sided tempered glass in the side windows • Cold rolled steel, static powder coated structure  • SUS-304 work surface  • tempered glass sliding front window • 600-800 lux fluorescent illumination • convenient opening for easy filter replacement • comprehensive main control panel • wind speed of 0.35+0.1 m/s in open window mode • UV safety mechanism for preventing UV exposure 100% UV-safe work chamber
