Environmental Express' disposable BOD bottles provide huge labor savings and improved quality in any environmental laboratory. Lightweight, unbreakable and recyclable, disposable bottles offer safety as well as convenience.
The US EPA recommends the use of Environmental Express disposable BOD bottles for EPA approved Methods.

Bottles are formed from PET resin, the most recycled plastic available. Simply use once and toss into the recycling bin.
Consider how many gallons of water per year you use washing, triple rinsing and DI rinsing your glass BOD bottles. With disposable bottles you conserve water and elliminate waste water treatment.
The use of clean, new bottles eliminates the problem of contamination from sample carry over or detergent residue. Our disposable bottles have an amorphous carbon coating which keeps oxygen from diffusing into or out of your sample. Bottles provide uniform blanks, high standard recoveries and quality test data.
Bottles come packaged and are individually numbered.

Yes the overcaps (D1050) are reusable.
Yes, we have nutrients available in multiple sizes. Please refer to the following product page: http://www.envexp.com/products/1-Wet_Chemistry/BOD-BOD_Testing/BODDW-Dilution_Water
These stoppers are made of acrylic which is safe to 90°C. They are not autoclave safe.
I have never run a BOD test using 60ml sized bottles. Using wastewater and DOmeter readings are the results comparable and acceptable to 300ml bottle results?
The most important thing to keep in mind when using a different size bottle is to keep the volume percentage of sample the same. If you are used to using 100 mL of sample in a 300 mL bottle you would need to reduce that down to 20 mL of sample in a 60 mL bottle. Similarly, when preparing the GGA standard you will need to make sure that you use 20% of what is normally used.
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.
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.
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.
This item ships from Charleston, SC.
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.
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.
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.
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.
No certification is provided with the BOD bottles.
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.
Yes, they are PET, number one recyclable. Please check with your municipality for further details.
They are yellow due to the amorphous carbon coating. This coating prevents oxygen migration in or out of the bottle.
