Title:
SYRINGE PUMP
Document Type and Number:
WIPO Patent Application WO2005016411
Kind Code:
A3
Abstract:
The invention is directed to a syringe pump (10) for the controlled addition of reagents to a chemical reaction. The syringe pump (10) has a reduced size for use as a cordless, hand-held laboratory device, and includes a driving mechanism for moving the plunger of a syringe (30) along the syringe barrel (32), a means for sensing a physical property of the reaction mixture (60), and a logic control circuit (44). The driving mechanism includes a motor (40), a drive shaft (26), a drive block (28), and a sliding barrel clamp (34). The logic control circuit (44) is programmable and controls the syringe pump (10) based on predetermined parameters. The syringe pump (10) adapts the delivery rate of reagent according to changes in physical properties of the reaction mixture (60) such as pH and/or temperature, thus providing a high degree of automated control over a chemical reaction.
