Frequently asked questions for: FertiCult™ Mineral Oil

FAQ1: Is the peroxide value tested of the mineral oil?
Yes, each batch of FertiCult Mineral Oil is tested for peroxide value (POV) and values have to be below 0.1mEq for the product to be released for sale.

FAQ2: Is FertiCult Mineral Oil a parrafin oil ?
Light parrafin oil is synonymous to Light Mineral Oil.
FertiCult Mineral Oil is in fact pharmaceutical grade light parrafin oil, that is double-washed with pharmaceutical grade, ultrapure water.

On top of the testing described in the European Pharmacopoeia, we perform extra and more stringent quality controls on the product (e.g. peroxide value test).

FAQ3: Is it normal that the oil becomes turbid in the fridge?
This is normal. Turbidity disappears when the oil is heated up again.

FAQ4: What is the storage temperature?
FertiCult Mineral Oil can be kept at 2-25°C, but can become turbid when stored in the fridge (turbidity disappears again when heated up).

FAQ5: What is the in-use stability?
FertiCult Mineral Oil is stable for 28 days after opening when sterile conditions are maintained and bottles are stored appropriately.

FAQ6: How to prepare oil?
Prepare dishes or aliquot the oil, and put the needed amount in a CO2 incubator at 37°C. If the aliquots are stored in holding devices that can be closed, leave the device open to allow the oil to saturate with gas. When preparing dishes, use an as thick as possible oil overlay (but make sure that the oil is not spoiled).

FAQ7: What is the difference between glass and PETG bottles?
Only the packaging material is different. There is no difference in product specifications and stability between glass and PETG bottles.

FAQ8: Why is the oil washed?
FertiCult Mineral Oil is washed to saturate the oil with water, to wash off possible hydrophilic residues/contaminants, and to reduce the amount of peroxides.
