Question/Answer

What is the height of this bottle? It is also suitable for method ISO 5815-1 with luminescence probes?

These bottles are the standard size of all glass BOD bottles. It measures 5.5\" H X 2.625\" W. The mouth has a flared opening 1.375\" wide. The bottles will fit all standard dissolved oxygen probes sold for BOD use. They are suitable for use with luminescence based or Clark cell probes.

Do you have a certification of the volume for BOD Bottles?

Disposable BOD bottles are volume accurate to 300 mL +/- 1%. The volume accuracy is determined by weight using an analytical balance certified with Class S weights traceable to NIST at room temperature. Certificates are not supplied with the bottles but every lot is tested to meet these requirements before they are released.

Do the disposible BOD bottles leach carbon (dissolved organic carbon)? How long does the carbon coating last?

Our disposable BOD bottles do not leach carbon. The carbon coating will last indefinitely, however it is not recommended that the bottles are re-used as cleaning the bottles may scratch the coating, thereby sacrificing the integrity of the oxygen impermeable bottle.

Do you receive a certificate of calibration w/ the bottles?

No certification is provided with the BOD bottles.

the volume of the bottle is 300 ml +/- ?? ml ? thanks fore a data sheet

The volume of our disposable BOD bottle is 300mL +/- 3mL. The uniformity of our disposable bottles has been found to be better than the uniformity of glass bottles due to inequalities that are inherent in the manufacturing process of glass bottles.

Can we recycle these bottles?

Yes, they are PET, number one recyclable. Please check with your municipality for further details.

Why are the bottles yellow?

They are yellow due to the amorphous carbon coating. This coating prevents oxygen migration in or out of the bottle.
