Page 4: Introduction
Introduction EasyPREP BOD-300 is an automated offline system for the sample preparation and analysis for Biochemical Oxygen Demand (BOD). With three liquid-handling peristaltic pumps, the EasyPREP BOD-300 adds seed and nitrification inhibitor as well as dilution water to perform sample dilutions. The low maintenance dissolved oxygen (DO) probe with either optical or membrane technology incorporates a blade stirrer, keeping the sample homogeneous and accelerating probe equilibration for DO measurement. -

Page 30: Dilution Water Preparation
• Remove any residual chlorine (by letting it evaporate or by titration after sodium thiosulfate addition). • Sample dilution: when diluting the sample, the sample volume should not be less than 1% the BOD bottle volume.

Page 33: Probe Operation And Maintenance
| 33 Guidelines on Probe Operation and Maintenance 8 .1 INITIAl SETUP Remove the ProOBOD cable/probe assembly from the shipping container and locate the instruction sheet that is included. This instruction sheet is important because it contains the calibration coefficients for your sensor cap. After using this sheet for general probe setup, be sure to store it in a safe place in case you need to reload these calibration coefficients in the unlikely event that they are ever deleted from the instrument and probe. -
Page 34: Maintenace And Storage
8 .2 MAINTENACE AND STORAGE This section describes the proper procedures for care, maintenance and storage of the ProOBOD probe. Do not attempt to access the probe motor assembly or open the probe body. Doing so will void any remaining warranty. The probe NOTE body should only be opened by a YSI Authorized Service Center. -

| 35 Figure 35. YSi Probe. Avoid touching the sensing end of the sensor cap during the following maintenance procedures. CAUTION • Remove the stir paddle from the probe by pulling it straight out. • Remove the old sensor cap from the probe by grasping the probe body with one hand and then rotating the sensor cap counterclockwise until it is completely free. -
Page 36: Rehydrating The Sensor Cap
8.2.1.4 Rehydrating the sensor CAP The Sensor Cap must remain in a moist environment. If you inadvertently leave your sensor exposed to ambient air for a period of more than approximately 8 hours it may dry out. If the sensor cap is allowed to dry out, it is likely to drift slightly at the beginning of your next study unless it is rehydrated. -
