"Here at Health Maintenance we've had a tremendous increase in our laboratory load. In one year we went from 300 to 1000 tri­ glyceride and cholesterol specimen tests per week. "Even without the extra load, hand-held pipetting resulted in a high percentage of errors. Many tests had to be done twice. This was intolerable, because most of our test results are required the same day with many needed in 45 minutes. "Obviously, we needed to automate our pipetting to handle the extra diluting. After we looked at other units, we chose the Grumman ADP-30SD dilutor/dispenser. "It has now been working for us for eight months. That comes to about 32,000 tests. Errors have been significantly reduced, and I haven't had to increase our costs. An equivalent yearly saving in time of over $10,000. "NowonderlthinktheADP-30SDiswell worth the money we invested'.'
