Our products do what they promise. But of course, we ourselves do too. That's why we always calculate our quotes for Spectro cleaning products in liters. After all, a liter is not always a kilo and vice versa. How exactly does that work? Account Manager Bram Maessen explains.

A kilo is a kilo. Whether it's feathers or lead. But that comparison fails when you compare kilograms and liters. A misunderstanding that, unfortunately, is difficult to clear up.

Bram: "Customers often compare our products with their existing assortment. And then I get the question why we are more expensive. I then explain that we calculate our prices in liters and not in kilograms as many other producers do. That gives a distorted picture. Indeed, it is not entirely fair. Because those "kilo products" not only appear unjustifiably cheaper; in reality, there is even less in a package. An unethical trick to better market your products."

Math

"Professional cleaners are often much heavier than water," Bram explains. "This is because the specific gravity, or relative density of a liquid, is regularly higher. With water, it's about 1.0. In that case, a kilo equals a liter. But with alkaline agents that contain a lot of lye, such as a foam cleaner or soap-like products, that density is 1.2 or sometimes even more. If you then fill a kilogram, the liter container is only slightly more than three-quarters full."

Super sin (and unsustainable)

For small volumes, the difference between liters and kilograms is hardly noticeable, according to Bram. But with 1,000-liter IBC containers, it makes a big difference. These are only filled to about eighty percent with such a foam cleaner. A great shame and totally unsustainable, both in transport and storage.

Even with a lower specific gravity, a calculation in kilograms is inconvenient, by the way. "Suppose you order a thousand kilograms of disinfectant hand gel," says Bram. "Then you get not one, but two IBC drums delivered. Of which the second is almost empty... Well: we don't do that at Spectro. What do we do then? We first visualize the specific gravity of the product and always make our quotations based on liters. Very honest and transparent!"
