Question/Answer

Are the D1025 BOD Stoppers considered disposable? What is the price?

The D1025 stoppers for the BOD bottles are intended to be used over and over again. Current pricing can be found by logging into the website or contacting your sales rep.

Are these bottles volume accurate?

The bottles are designed to hold 300 mL of liquid. There is no graduation line on the bottle anywhere to signify the fill line to achieve this volume. Because of the natural inconsistencies in forming glass products there will be some deviation from bottle to bottle.

What does this book cost and how do I order it?

The book can be ordered online if you have an online login. Otherwise please call us at 800-343-5319 to place an order.

What is the max temperature the bottle can handle? We are trying to see if the bottle can withstand a hot water bath.

The bottles are molded from PET, which has a melting point of 260°C.

Where does the item ship from?

This item ships from Charleston, SC.

How many capule(s) per volume of dilution water?

The instructions included with Polyseed call for the contents of one capsule to be added to 500 mL dilution water. However, the formulation is flexible in that it allows each laboratory to adjust this volume of water in order to get the seed strength in whatever range is desired.

Can I use glass stoppers?

Yes, the standard glass stoppers will fit into these bottles.

Does Env Express have a program for recycling the disposable BOD bottles? Or is that something we would have to do locally through a recycling program?

We do not have a recycling program for the BOD bottles. They are number 1 PET plastic and are easily recyclable. Check with your local municipality for recycling programs and instructions in your area.

Do you have data on how the disp BOD bottles work for a twenty day BOD?

Because of the lack of information regarding QC we have not gathered any data for tests lasting longer than 5 days for our disposable BOD bottles. We do have customers who have used the bottles for longer term BOD projects. It will depend entirely on the composition of the sample and how it might react with the coating on the bottle.

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.
