Take the burden out of buffer exchange with Unagi & Big Tuna

The Problem

Buffer exchange and concentration of proteins requires undivided attention and takes up your valuable time, even when you’re dealing with only a handful of samples. Traditional approaches keep you chained to the bench and keep you wondering about sample quality and whether you’re going to recover enough sample. With manual methods, achieving reproducible exchange and concentration goals with all samples is always a hassle. It becomes the worst part of your day when the number of samples increases.

The Solution

Unagi is the first completely hands-free benchtop buffer exchange solution that automates the entire buffer exchange and concentration process. Set up takes only minutes for up to 8 samples with starting volumes between 0.5-8 mL. Unagi’s set-up-and-go software puts process control in your hands, so exchange and concentration targets hit the mark every time — with sample recoveries of at least 96%.

Is your sample load beyond the throughput of Unagi but you still want to automate your buffer exchange? Big Tuna takes the same technology and throttles the throughput to 24x 0.5-8 mL or 96x 100-450 µL parallel exchanges.

The Proof

Come check out how fast & easy it is to set up buffer exchanges for your proteins on Unagi or Big Tuna then tend to more thought-provoking tasks in the lab. We’ll show you data to highlight how Unagi and Big Tuna play nice with downstream protein characterization tools and how consistent, hands-off exchanges can make your days in the lab a breeze.
