Abstract
Abstract A fluid dispensing system comprises a first linearly translatable plate and a second linearly translatable plate mounted below the first plate at 90 degrees relative thereto, the first plate being displaceable in one direction and the second plate being displaceable in another direction, said dispenser including an overhead fluid dispenser for dispensing calibrated amounts of fluid into each well of a multi-welled dish wherein the wells are spaced apart in rows and columns.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
131 words
A fluid dispensing system for dispensing fluid into a receptacle having a plurality of spaced apart receiving wells comprising: (a) a first linearly translatable plate adapted to carry the receptacle; (b) a second linearly translatable plate mounted below said first linearly translatable plate at 90 degrees relative thereto; (c) means operatively associated with said first linearly translatable plate to cause a finite predetermined displacement thereof in one direction; (d) means operatively associated with said second linearly translatable plate to cause a finite predetermined displacement thereof in a second direction; (e) means for dispensing fluid in each well of said receptacle; and (f) means operatively associated with said fluid dispensing means to cause a predetermined amount of fluid to be dispensed from said fluid dispensing means into each well of said receptacle.
Claim 2
Dependent Claim
131 words
A fluid dispensing system for dispensing fluid into a receptacle having a plurality of spaced apart receiving wells comprising: (a) a first linearly translatable plate adapted to carry the receptacle; (b) a second linearly translatable plate mounted below said first linearly translatable plate at 90 degrees relative thereto; (c) means operatively associated with said first linearly translatable plate to cause a finite predetermined displacement thereof in one direction; (d) means operatively associated with said second linearly translatable plate to cause a finite predetermined displacement thereof in a second direction; (e) means for dispensing fluid in each well of said receptacle; and (f) means operatively associated with said fluid dispensing means to cause a predetermined amount of fluid to be dispensed from said fluid dispensing means into each well of said receptacle.
