Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to
24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Quantitative analysis of total mycotoxins in metabolic extracts of four strains of Bipolaris sorokiniana ( Helminthosporium sativum)[Reference:
WebLink]
METHODS AND RESULTS:
The production of total mycotoxins by four strains (3, 5, 8, and 18) of Bipolaris sorokiniana was analyzed using ethyl acetate and ethyl ether as solvents. Physiologically, strain 3 was the best one for the production of mycelium, whereas strain 5 was the best one for the production of total mycotoxins.
CONCLUSIONS:
According to HAT-FTIR spectroscopy, the composition of ethyl ether was more complex, allowing for the identification of OH and CO axial stretching and CH3 angular deformation present in prehelminthosporol and Prehelminthosporolactone.
