Abstract
An embodiment provides a method for moving precise volumes of fluid using a linear peristaltic pump, including: operating the pump for a first portion of a pump cycle, wherein the operating the first portion dispenses a first reagent, wherein the pump comprises a motor and a cam; pausing the pump for a period of time; and operating the pump for a second portion of the pump cycle, wherein the operating the second portion dispenses a second reagent. Other aspects are described and claimed.

A method for moving precise volumes of fluid using a linear peristaltic pump, comprising:
- operating the pump for a first portion of a pump cycle, wherein the operating the first portion dispenses a first reagent, wherein the pump comprises a motor and a cam;
- pausing the pump for a period of time;
- and
- operating the pump for a second portion of the pump cycle, wherein the operating the second portion dispenses a second reagent.
A device for delivering a precise volume of fluid using linear peristaltic pump, comprising:
- a motor;
- a cam;
- a motor controller;
- a processor;
- a memory device that stores instructions that, when executed by the processor, causes the system to:
- operate the pump, using the motor controller, for a first portion of a pump cycle, wherein the operating the first portion dispenses a first reagent;
- pause the pump, using the motor controller, for a period of time;
- and
- operate the pump, using the motor controller, for a second portion of the pump cycle, wherein the operating the second portion dispenses a second reagent.
A product for delivering a precise volume of fluid using a linear peristaltic pump, comprising:
- a computer-readable storage device that stores executable code that, when executed by a processor, causes the product to:
- code that operates the pump, using a motor controller, for a first portion of a pump cycle, wherein the operating the first portion dispenses a first reagent;
- code that pauses the pump, using the motor controller, for a period of time;
- and
- code that operates the pump, using the motor controller, for a second portion of the pump cycle, wherein the operating the second portion dispenses a second reagent.
