What's a new scintillation cocktail that will improve counting efficiency at 30%-50% water content? HANDIFLUOR New HANDIFLUORTM SCINTILLAR®\s making waves. It's a complete cocktail for liquid scintillation counting that does the job you've always wanted done. HANDIFLUOR handles both aqueous and nonaqueous samples, forming brilliant clear solutions or firm translucent gels when you need them. And HANDIFLUOR really shines when you count the tough ones, like tritium at low concentrations. You need the extra 50%—100% counting efficiency that HANDIFLUOR can give you in these tough spots... and it works at both low and ambient temperatures. You'll find that every lot of HANDIFLUOR is controlled and use-tested for freedom from quenching and minimized chemiluminescence. In short, every lot is controlled for optimum counting efficiency against stringent Mallinckrodt standards—the highest in the industry. Compare HANDIFLUOR with your present cocktail.
