Buy cod digestion vials for measuring water quality

A series of reactors to fit varying numbers and sizes of tubes, including 16mm, available either as single or double blocks. The DRB200 thermostat ideallycomplements Hach COD, TOC and

2021/06/11 · Chemical Oxygen Demand is an important water quality parameter because, similar to BOD, it provides an index to assess the effect discharged wastewater will have on the receiving environment. Higher COD levels mean a greater amount of oxidizable organic material in the sample, which will reduce dissolved oxygen (DO) levels.

Camlab water mercury-free COD can be measured in three ranges. LR (3-150 mg/l) is applicable for final effluents and treated waste water. MR (20-1500 mg/l) is suitable for measuring crude sewages, untreated and partially treated waste water. HR (200-15000) is suitable for monitoring trade effluents. Please note a reactor is required for COD

2019/01/23 · Luminescence lifetime-measuring sensors are less affected by dye degradation than intensity-measuring sensors, which means that they will maintain their accuracy even with some photodegradation 24. However, optical dissolved oxygen sensors usually require more power and take 2-4 times longer to acquire a reading than an electrochemical DO sensor 7, 14 .

It is also called a colorimetric tube and is a common accessory for water quality testing instruments such as COD analyzers. In the process of water quality testing, COD tester, total phosphorus tester, total nitrogen tester, total chromium tester and other water quality test instruments need to be used in conjunction with a digester, usually with a digestion tube after digestion, and then use

COD Digestion Vials. Minimize handling of corrosive and toxic chemicals and eliminate pipetting hazardous reagents. 16 mm Test ’N Tube for Hach DR 6000™ and DR 3900™ Spectrophotometers.

Vials contain premeasured digestion reagents suited to your expected range of COD, so there is no measuring of harmful chemicals- simply add your sample to the vial and digest. Caution: The vials

• Take three COD vials with stopper (two for the sample and one for the blank). • Add 2.5 mL of the sample to each of the two COD vials and the remaining COD vial is for blank; to this COD vial add distilled water. • Add 1.5 mL of

This measuring station from AQUALYTIC® allows the accurate, rapid, and economical determination of waste water COD levels (Chemical Oxygen Demand). Includes a COD photometer, 25 tube tests covering lower measuring ranges, a reactor block for sample digestion and a tube stand. Photometer specifications. Range: 0 bis 15.000 mg/L.

Qty. The K-7365 COD Vials Kit was designed to accurately measure COD in water from 0-1,500 ppm. The determination of Chemical Oxygen Demand (COD) is widely used in municipal and industrial laboratories to measure the overall level of organic contamination in wastewater. The contamination level is determined by measuring the equivalent amount of

Accommodates Most Test Vials The DRB 200 reactor can heat solutions in round vials of two different sizes. Small, 16-mm diameter vial wells are suitable for Hach COD, UniCell™, TOC, and Test ’N Tube vials

2010/10/14 · A COD reactor/heating (150 C) block and a colorimeter are turned on so that both instruments are allowed to stabilize. Pre-prepared low-range (3-50 ppm) or high-range (20-1500 ppm) vials are selected for the COD test based on

U-50 series Multi-parameter water quality checker enables to measure and indicate the monitoring result simultaneously up to 11 parameters with one unit. Tough & powerful design, considering user friendly field monitoring on site

Pre-filled with COD reagents, these digestion vials come in either EPA-approved or mercury-free versions for low-, standard-, and ultra-high-range analysis. Each lot is tested to ensure superior quality from the cap and vial to the chemical contents. Glass vials are 16 mm x 100 mm to work with your existing COD reactor and spectrophotometer.
