New double-duty pipette makes your money work twice as hard.
'It's a dispenser!"
"It'sadilutor!"
This new Grumman ADP-30SD switches readily from dispensing to diluting and back again. Orjustsetitupforonefunction and keep it there. Either way you'll get a real bargain, because its cost/performance value is far greater than competitive units. As a dilutor you can pick up 0.002 to 1 ml and dilute with 0.05 to 20 ml with ratios up to 10,000:1, depending on which of six diluting range combinations you choose. The ADP-30SD functions efficiently at ratios as low as 5:1, unlike some which require about 50:1 ratio for efficient operation. As a dispenser, you combine two liquids from 0.002 ml to 20 ml of each, depending on range selected. And you do it with repeatability of up to one part in a thousand. The MDA-30 (optional) multiplier can increase the output in integral steps from 2 to 10 times. An optional footswitch makes this a fast Reg. DuPont ™ ® Reg. Corning
operating unit. The high visibility micrometer volume-setting panel improves accuracy and speeds changeover. The priming cycle is virtually automatic, faster, requiring no separate injection by hypodermic when diluting. Standard disposable tips matched to sample size. Teflon' and Pyrex* passageways handle a tremendous variety of materials as well as facilitating cleaning. This Grumman dilutor/ dispensing pipette meets appropriate FBS and NBS standards and specifications. We'd like to send you a brochure on the ADP-30SD complete with accessories; and give you a free 10-day demonstration.
