Barium fluoride windows Edmund Optics introduces TechSpec Barium Fluoride (BaF2) Windows. The windows are suitable for use in a wide variety of applications, including infrared (IR) spectroscopy, as they offer wide broadband transmission extending from the deep ultraviolet (UV) to the long-wave IR. They are available in four models with diameters from 5 to 50 mm. With good transmission from 200 nm to 14 µm, the windows take advantage of barium fluoride’s low index of refraction (1.48), which provides high transmission without the need for antireflection (AR) coatings. The windows can be used at temperatures up to 800°C in a dry environment. They are said to be resistant to high-energy radiation and feature a Knoop hardness of 82. Barium fluoride is a very fast scintillator for the detection of X-rays, gamma rays and other high energy particles, such as 511 keV gamma photons in positron emission tomography (PET). It is also used to detect high-energy (10-150 MeV) neutrons and separate them from simultaneously occurring gamma photons using pulse shape discrimination techniques.

Agar media dishes Sartorius Stedim Biotech has introduced Microsart @media to complement Microsart @vance, a product line for microbiological quality control in these sectors. The Microsart @media line of agar media dishes is for microbial limits testing according to the USP (Chapter <61>) and EP (Chapter 2.6.12). They are pre-filled with various agar media types, such as Tryptic Soy Agar or R2A Agar, sterile packaged and ready to use in combination with Microsart @filter units. The product features an innovative lid that allows touch-free transfer of the filter membrane onto the media without using any tweezers. In addition,
