WE MAKE STRUCTURE SOLUTIONS CRYSTAL CLEAR!

Give your pump a Harvard education. Make your laboratory work more efficient than ever before. The New Harvard Apparatus Educated Pump System with a micropro­ cessor-based, interactive computer system is easy to use. You literally turn it on and let the software do all the work. Create any protocol by specifying up to six hundred flow rate/time events. Or write your own programs in BASIC to instruct your Educated Pump to change its delivery rate to fityour experiments. And the hard-copy printer will report, on demand, the activities it has performed. For information on the new Harvard Educated Pump System or how to retrofit most Harvard pumps call 1-800-343-4912, in MA 617-655-7000 or send for our brochure. HARVARD
