Quick answer: Both the 51-well and 97-well trays are enzyme-substrate MPN (Most Probable Number) quantification trays used for coliform and E. coli testing in water. The key difference is well structure, measurement range, and reading method — the 51-well tray suits clean, low-concentration water, w

Third-party water quality testing agencies commonly face a major challenge during peak business seasons: water sample volumes surge dramatically, but manual plate-sealing efficiency remains extremely low. Production capacity simply can't keep pace with incoming orders. Traditional sealing equipment

For laboratory procurement managers,environmental testing institutions,water plant laboratories,and industrial quality control departments,purchasing suitable water testing consumables is not a simple bulk ordering work.The quality of 97-well trays directly affects the accuracy of MPN microbial dete

Commonly used instruments and equipment for detecting total coliforms, Escherichia coli, and fecal coliforms, along with a summary of laboratory routine configurations, can be directly used for laboratory inventory, acceptance, and procurement:

The enzyme substrate method is currently a simple, accurate, time-saving, and highly efficient analytical approach. Below we outline its methodological advantages and product features:

Enzyme Substrate Quantification Sealing Machine: Consisting of a programmable quantitative sealing machine, 51- or 97-well detection plates, 100mL quantitative bottles, and enzyme substrate detection reagents. Water sample detection scope: drinking water, source water, bottled water, reclaimed water
