What is paraffin used for in IVF ?
Paraffin oil is used in in vitro fertilization (IVF) as a protective overlay on culture media drops to stabilize pH, maintain temperature, and prevent water evaporation.

Purpose and Function
Light-Protective Packaging for Embryo and Gamete Safety
To ensure the highest level of safety for embryos and gametes, NidOil™ is packaged in amber, screw-top bottles that protect against light-induced changes. This precaution is based on documented cases where paraffin oils became embryo-toxic after exposure to light on laboratory benches.
By shielding the product from harmful light exposure, we help maintain its integrity and safeguard sensitive biological materials during use.
