Water quality coliform enzyme substrate detection system:
It consists of LK-2010 program-controlled quantitative sealing machine, 51 or 97-well quantitative detection tray, 100mL quantitative bottle and enzyme substrate detection reagent. Scope of water samples: drinking water, source water, bottled water, medium water, secondary water supply, pipe network water, wastewater, food water, livestock water, medical water, etc. The detection method uses Escherichia coli to produce a β-galactosidase-decomposing color source substrate-ONPG (Ortho-nitrophenyl-β-D-galactopyranoside) to make the culture solution yellow. Escherichia coli produces β-glucuronidase to decompose MUG (4-methyl-umbelliferyl-β-glucuronide) to fluoresce the culture medium at a wavelength of 366 nm to qualitatively quantify the total amount of water. Coliform, fecal coliform (heat-resistant coliform) and Escherichia coli. Serial numberIndicator name

Coaxial Power D-Sub Solder Cup
Coaxial Power D-Sub Solder Cup Contacts with Mixed or Full Layout
Transmit Radio Frequency Signals
The Coaxial D-Sub have like the Power D-Subr replaced the two rows in a Standard Density connector with a coaxial contact that take up about the same size as the two rows of signal contacts. The Coaxial D-Sub is exactly the same size as the Standard Density connector but instead of example 9 positions of signal pins it has 2 power contacts , or instead of 37 positions of signals it has 8 coaxial contacts.
The Impedance for the coaxial contacts are 50Ω or 75Ω
The Coaxial D-Sub with Mixed Layout mixes both coaxial contacts and signal contacts in the same connector. For example the same size as a 15 position Standard Density D-Sub you can have what we call a 7W2, which means there is 7 contacts where 2 of them are coaxial contacts, which means there are 5 signal contacts, so 5 signals and 2 coaxial. See the Layout in the Tech Specs on the bottom, there are a lot of combinations of the Mixed Layout alternative.
Antenk's Coaxial D-Sub connectors are available in 5 standard shell sizes with 23 multiple contact arrangements. These reliable, robust combination d-sub connectors allow a combination of signal and coaxial contacts in cable mount, vertical board mount & right angle board mount termination type variations.
