AlgaBoost EPA-1002/1003 no EDTA is a 400x concentrate of the medium used for Toxicity Testing. It is identical to AlgaBoost EPA-1002/1003, except for the absence of EDTA.
Application : medium of choice for heavy metal toxicity tests; the exclusion of EDTA from this formulation allows more sensitive detection of heavy metals.
Makes: When diluted in water according to instructions, it makes the following media:
1. EPA Test Method 1002.0 (but EDTA free) (Daphnid Ceriodaphnia dubia, Survival and Reproduction Test).
2. EPA Test Method 1003.0 (but EDTA free) (Green Alga, Selenastrum capricornutum, Growth Test).
2 litres distilled water
+ 1 x 5ml Syringe Part A
+ 1 x 5ml Syringe Part B
2 litres USEPA-1002/1003 medium (EDTA-free)
Nutrient Balance: When added to your seawater + freshwater mix (seawater : freshwater = 4 : 1.1 ) according to the accompanying
instructions, the combined parts of this formulation will provide the following nutrient levels:
|Nutrient||Final conc per litre (g/l)|
Nutrient Balance: When added to freshwater according to the accompanying instructions, this formulation will provide the following nutrient levels:
How is the product supplied ? - As a 2-part mix, in packs containing 12 kits (enough to make 12 x 2 litres of EPA 1002/1003 medium). Each part of the 2-part mix is sterile and is provided in a convenient 5ml syringe; the two syringes are provided in a sealed sterile pack.
To Make the Medium: - Open a 2-syringe kit. Then add the the contents of one 5ml syringe to 2 litres of pure water, mix thoroughly, then add contents of the other 5 ml syringe and mix (instructions accompany the product). Aerate the mixture, adjust pH if necessary (recommended for EPA method 1003.0) and filter sterilise.
NOTE: EPA-1002/1003 is sterile; the final sterilisation step (described above) is necessary only if diluent (water) is not sterile and/or if sterile technique has not been used while preparing the final medium.
