- 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.

- 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.

- 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

- 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
|
|

|
- 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
|
- 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
|
- 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)

|
- 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
