YSI 2700-D Select Dual-Channel Biochemistry Analyzer Glucose Lactate

YSI 2700-D Select Dual-Channel Biochemistry Analyzer Glucose Lactate

The YSI 2700-D Select is a benchtop dual-channel biochemistry analyzer made by Yellow Springs Instrument Co., Inc. (YSI) of Yellow Springs, Ohio. It uses enzyme electrode technology to measure the concentration of specific metabolites in liquid samples, delivering results in roughly 60 seconds per sample. The instrument supports two simultaneous analyte channels, making it well suited for high-throughput bioprocess monitoring where multiple substrates or byproducts need to be tracked in parallel.

Applications

The YSI 2700 Select series is a well-established platform in bioprocess and cell culture laboratories. It is used to monitor key nutrients and metabolic byproducts in fermentation broths, mammalian cell culture media, and other biological process streams. Typical users include pharmaceutical and biopharmaceutical manufacturers, academic research labs, and contract research organizations running fed-batch or perfusion bioreactor processes. The dual-channel configuration allows simultaneous measurement of two analytes — commonly glucose and lactate together — providing real-time data used to adjust feeding strategies, assess culture health, and maintain consistent productivity. YSI introduced the 2700 Select platform in the 1990s and it became a standard reference instrument in bioprocess QC labs. Enzyme electrode-based analyzers like the 2700-D remain relevant in facilities that have validated SOPs around the platform, making this a practical option for labs seeking a proven, cost-effective replacement unit.
