PR160L-390nm 化學燈

LED PhotoReaction Lighting


Newly Designed Linear Reflector

  • A linear illumination area with more even light distribution
  • Higher intensity than the previous model PR160 – average intensity is up to 30% higher than that of PR160
  • Upgrade kit is available if you have the PR160.

Kessil PR160L new reflector

Finely Tuned Wavelengths

  • Seven precise wavelengths to choose from – 370nm, 390nm, 427nm, 440nm, 456nm, 467nm, 525nm. Customized solution is available (540nm, 595nm, 640nm, 740nm, etc)
  • Study in-depth and optimize photoexcitation/photoredox reactions to save time and cost

Increased Intensity for Higher Efficiency

  • Intense and penetrating light reduces reaction times and cost (50% brighter than our already intense Kessil H150 Blue)
  • 4 levels of intensity control allows you to study the functional relationship between intensity and yield

Flexibility & Simplicity

  • Easily configure for different geometries (vials, test tubes, flasks, etc…)
  • Add more PR160Ls to scale up your experiment and increase intensity
  • Multiple mounting: PR160 Rig w/ Fan Kit, lab clamp, Kessil Gooseneck, etc.

Upgraded PR160 Rig With Fan Kit

  • Specifically designed mounting to turn system into photoreactor for typical laboratory photocatalytic reactions
  • Full adjustability and secure mounting provides consistency and accuracy
  • Comes with a powerful fan to blow air efficiently (proved to be more efficient than clamp desktop fan) to keep the reactions at room temperature as much as possible
  • Comes with light-blocking shields for lab safety, which blocks all UV light and most blue light

Designed for Consistency and Reliability

  • Easy to operate
  • Reliable results and repeatable reactions, perfect for commercial setups or flow photochemistry
  • Consistency between every unit
    • Peak wavelength within ±1nm*
    • Optical output within 3%*
      *Standard Deviation

New Products Added!

  • UVA LED 370nm for different applications such as general photochemistry, photocycloaddition, UV Curing, etc.
  • Replace high pressure mercury lamp. Safer, environmental friendly, longer lifespan.
  • Green LED for Photoenzymatic catalysis involving enzymes/protein

“Photoredox 暫時最主要是在有機化學學術領域,使用光和光催化劑(catalyst) 改變compound, 令原來要用幾個月時間甚至沒有辦法製造的compound 在幾個小時內就可以製造出來。這亦代表藥廠可更快和更便宜拿到造藥原材料

普林斯頓大學的Professor David Macmillan 是這領域的專家和領導者,原先提倡使用一般家用CFL 燈具,因為價格低和容易找到,但是光譜太廣和強度不足,研究慢慢找出光的波長是很重要的一環。這時DiCon/Kessil 的優勢就更顯突出。因為我們是自家製造LED chip 一條龍到燈具,所以我們可以做到很精準的波長,而且燈具的強度亦很足夠,很適合Photoredox 這個應用。美國這邊的藥廠現在都爭先去研究出適當的方法及方程式。世界各地尤其是歐洲的研究所都對這方面很有興趣,希望找出特別的方程式。

最近Macmillan 教授用Photoredox 發明出一種新的藥物測試方法。現在一般的藥物測試都是使用人體去測試藥物到底去到身體那裏,有沒有去到好的地方壞的地方或是好壞的地方也去到,而現在要去追蹤這些藥物是有一定的難度,需要幾個月甚至幾年時間去將藥物變成有輻射性去追蹤。Macmillan 教授使用Photoredox 用幾個小時就改變了藥物的Compound,把藥物變成有輻射性,可以被追蹤,令一般藥物的研發時間由14年左右大幅減少。而教授在這次實驗當中也是使用我們Kessil的燈具,他在他的研究paper都有提及Kessil.”
