Hach Company Chlorine (Free & Total) Color Disc Test Kit, Model CN-66
This color disc test kit uses powder DPD reagent that reacts with chlorine more quickly than tablet-form DPD, giving more accurate results. Powder DPD also has a considerable advantage over orthotolidine, a hazardous substance sometimes used as a free and total chlorine test reagent. Hach Chlorine Test Kits are manufactured by Hach to ensure compliance with stringent quality control standards. Kit contains 100 tests.*This product has not been evaluated to test for chlorine and chloramines in medical applications in the United States.
Hach Company MEL/MPN Total Coliform and E. coli Laboratory
This MEL provides all the hardware to carryout the Most Probable Number (MPN) method. In additon to potable water, the MPN method is ideal for wastewater samples and nonpotable samples, because the analyst can accomodate highly turbid samples which would otherwise require filtration. MEL/MPN Total Coliform and E. Coli Laboratory. Includes: portable Incubator, portable UV lamp, marker, thermometer and sampling/filtration consumables for 50 tests. Media is not included (order separately - see manual on Downloads page). For wastewater applications, order dilution water 1430598.
Hach Company MultiTest kit case (5.7 x 8.1 x 2.6 in), blue polypropylene
Durable blue polypropylene carrying case allows easy transport of items for field testing.
Gold Biotechnology Inc Tris (Tris Base) 1 kg
GoldBio Tris has the highest purity available on the market. Short for Tris (hydroxymethyl) aminomethane (THAM), Tris is an organic compound often used in buffer solutions such as TAE or TBE for electrophoresis gels. Tris is highly soluble in water and is useful in the pH range 7.0-9.0. It is used in the preparation of Laemmli buffer, one of the most common SDS-PAGE buffers. In addition, Tris can also be used for many custom running and loading buffers, most often with glycine and SDS. The use of single-junction pH electrodes that contain silver should be avoided when determining the pH of a solution containing Tris buffer.
