Bottle-Top Dispenser

The dFlow Electronic Bottle-Top Dispenser is a motor-controlled digital dispensing system designed for precise, fatigue-free delivery of laboratory reagents directly from reagent bottles . Featuring a volume range of 0.1-99.9mL with 100μL resolution, 16 adjustable speed levels, and a TFT display module, this dispenser provides accurate volume delivery (10mL: R=0.5%, CV=0.3%) compliant with DIN EN ISO 8655 standards .

The external remote control panel allows operation without manual disturbance, significantly reducing the risk of repetitive strain injury while keeping operators away from hazardous chemical contact . Two operation modes—dispenser mode for single aliquots and stepper mode for continuous multi-volume dispensing—provide versatility for diverse laboratory workflows . A recirculation feature minimizes costly reagent waste by allowing priming without discarding expensive solutions .

For the clinical laboratory scientist and medical technologist, the dFlow electronic dispenser supports accurate dispensing of clinical chemistry reagents, immunoassay buffers, molecular biology reagents, and pharmaceutical quality control samples. The stepper motor drive ensures smooth, consistent operation across 16 adjustable speed levels, accommodating liquids of varying viscosities . The fluid path features chemically resistant materials (borosilicate glass cylinder, FEP tubing, PTFE components) compatible with a wide range of laboratory reagents . Included bottle adapters (S40, GL25, GL28, GL32, GL38) allow attachment to various reagent bottle thread sizes via the standard GL45 base .

For the patient undergoing diagnostic testing, precise and consistent reagent dispensing using the dFlow electronic bottle-top dispenser ensures that clinical chemistry, immunoassay, and molecular diagnostic test results are accurate, reliable, and reproducible—supporting appropriate clinical decision-making across laboratory medicine and pharmaceutical quality control applications.
