Reliable probes that save you time…
“The SCOUT probes give more reliable high resolution than other suppliers, which often have a dud or two from every box, hence why I recommend them.” - Dr James Thomas, University of Oxford, UK
“It was much easier to set up “good” imaging parameters with these tips compared to tips from other suppliers. I will definitely recommend these.” - Fouzia Bano, University of Leeds
