Abstract
  • Manual sample handling, such as moving samples or recording data visually, is a tedious and error prone process.  Sample Handling Operation Wizard (SHOW) is a system developed to guide manual sample handling in laboratories.  It comprises a sample tray mounted on a 15” flat - panel computer monitor.  Up to four transparent micro titer plates and up to 8 reagent vials may be placed on the sample tray. Images of the wells of the plates and vials are generated on the monitor and controlled by computer software.

Abstract (continued)
  • These images are directly aligned with the positions of the physical wells or vials.  By highlighting the wells or vials involved in a sample handling step of a predefined protocol, manual operations can be performed with precise guidance from the system.  As a result, the risk of locating a wrong sample or placing a sample at a wrong location can be minimized, and sample handling operations become more efficient and less stressful.

Introduction
  • Manual sampling handling
    • Tedious
    • Error-prone
    • Stressful
    • Lack of tracking
  • Automated liquid handlers
    • Complex
    • High maintenance cost
    • Not portable
5
Objective
  • Display graphic guidance underneath each sample and text memo in close vicinity for manual sample handling
  • Handle samples without memorizing or reading instructions of a protocol
  • Define and store sample handling protocols
  • Modify and test sample handling protocols
  • Facilitate automatic recording sample handling details, such as amount transferred and the time of transfer

Demo Application 1
- Parallel Synthesis
  • Protocol: 4 x 5 library
  • Task 1
    • Reagent A dissolution into vials
    • Reagent A transfer from vials to 24-well synthetic plate
  • Task 2
    • Reagent B dissolution into vials
    • Reagent B transfer from vials to 24-well synthetic plate
15
Demo Application 2
Compound Plating
  • Protocol: Compound Plating
  • Task 1
    • Transfer from 24-well synthetic plate to 48- well storage plate
    • Transfer from 24-well synthetic plate to 96- well QC plate
    • Transfer from 24-well synthetic plate to 384-well assay plate
16
Demo Application 3
Serial Dilution
  • Protocol: Serial Dilution
  • Task 1
    • Transfer from stock solution to Row A of a 96-well assay plate
    • Split samples to Rows B to H with two-fold decreasing volumes
    • Add solvent
17
Potential Application
- Data Recording
  • Protocol: Record MIC (minimal inhibition concentration for bacterial growth)
  • Task 1
    • Load a serial dilution assay plate
    • Visually inspect cell growth
    • Record MIC by clicking on the well with the lowest concentration and no cell growth (under implementation)
18
Conclusion
  • The SHOW system provides guidance to manual sample handling
  • Flexible design allows different plate formats
  • System is simple and inexpensive
  • Manual sample handling becomes more accurate and less stressful
