BIOLOGY: FEATURED PRODUCTS a. Ethanol Sensor
a
E T H - B TA
ORDER CODE
Use the Ethanol Sensor to measure the concentration of ethanol in air above an aqueous sample. It can be used to determine the rate of ethanol production during fermentation or to measure the discrete amount of ethanol in a given sample.
b. Tris-Compatible Flat pH Sensor ORDER CODE
b
F P H - B TA
The Tris-Compatible Flat pH Sensor uses a double-junction electrode, making it compatible with Tris buffers and solutions containing proteins. The flat glass shape also makes it ideal for measuring the pH of semisolids, such as food or soil.
Measuring CO2 gas and ethanol production during fermentation
c. NEW PAR Sensor ORDER CODE
NEW
c
PA R - B TA
The PAR (Photosynthetically Active Radiation) Sensor measures photosynthetic light levels in both air and water. It features a waterproof sensor head and can be used to measure Photosynthetic Photon Flux Density (PPFD) from sunlight and electric light sources. It is sensitive to visible light in the spectral range that is used by plants in photosynthesis (400–700 nm). This sensor is ideal for experiments investigating photosynthesis and primary productivity, and can also be used in many agricultural and environmental science applications.
d. BioChambers
2000 mL, ORDER CODE B C - 2 0 0 0 250 mL, ORDER CODE B C - 2 5 0
d
BioChambers provide a way for both CO2 Gas and O2 Gas Sensors, or one of these along with the Ethanol Sensor, to be used at the same time in a closed system.
