Why disposable tip dispensers are superior to disposable syringes

Posted by Susanna Laurén on March 13, 2017

If you are working with inks, paints or other contaminating liquids and thinking of measuring contact angles, we have good news for you. By having a disposable tip dispenser, you can get away with messy sample handling and perform your measurements even faster.

Vanishing interfacial tension measurement - a fast route to minimum miscibility pressure

As the exploration of new oil reservoirs is slowing down, there is a need to be able to utilize the current oil reservoirs more efficiently. After primary and secondary recovery, at least 50% of the original oil is left behind in the reservoir [1]. Additional injections of fluids like polymers, surfactants or different gases are commonly used to displace and dissolve some of the remaining oil. This process is called tertiary or enhanced oil recovery (EOR) and can lead to an additional 8-16 % uptake of original oil in place (OOIP) [1].
