behrotest^® BOD sample dilution units

behrotest® BOD sample dilution units are reliable and easy to use. Use the matching accessories - from the dilution water tank with cooling coil over thermostat-circulation pump to the allylthiourea fine dosing function - to design entire workstations. Define BOD5 pursuant to ISO 5815-1, DIN EN 1899-1 (=DEV H 51) to achieve a significant reduction of personnel expenditure and costs.

	Similar to BSB 4A, but with 3 graduated mixing cylinders of 1 l volume, each with magnetic stirrer. Permanently mounted twin head peristaltic pump for increased flow rate.

behrotest^® BOD bottles (Karlsruhe type) with stoppers

The special extension of the bottle-neck retains the water displaced by the insertion of the stopper or the oxygen electrode. This design guarantees neat working processes and ensures that no oxygen can get into the samples and corrupt the measurement results.
