PACKING and SHIPPING
How is our diffusion pump oil packaged?

We offer diffusion pump oil in three very convenient packages including 5kg, 10kg, and 25kg plastic containers. For large quantities, we can package the oil in either 200kg metal drums or 1000kg IBC totes. To ensure there are no leaks from our plastic containers, we make sure the bottle caps are 100% secure and sealed. Further more, the plastic containers are lined with a plastic liner before being packaged in a very sturdy, double-layerd cardboard box. An outside layer of bubble wrap surrounds the cardboard box to add yet another layer of protection. We can also package the diffusion pump oil based on your requirements. 

 
When will my order ship?

We keep a large volume of diffusion pump oil in stock, we guarantee all orders to leave our facilities within 10 business days of payment confirmation. While this is so, our lead times are usually much lower.
