|| '''Slide Number 1'''

'''Title Slide'''
||Welcome to this spoken tutorial on '''Solution Transfer Modes in Vlabs'''.
|-
|| '''Slide Number 2'''

'''Learning Objectives'''
||In this tutorial, we will learn about,

3 different modes of solution transfer in Vlabs

Precise transfer

Significant transfer and

Realistic transfer

|-
|| '''Slide Number 3'''

'''System Requirement'''
||Here I am using,

'''Ubuntu Linux '''OS version 22.04

ChemCollective Virtual labs version 2.1.0

Java version 11.0.5 and

A working internet connection

|-
|| '''Slide Number 4'''

'''Prerequisite'''

||To follow this tutorial,

Learners must be familiar with the ChemCollective Virtual labs interface.
|-
|| Type ChemCollective virtual labs on Google search page.
||For this demonstration I will open the '''ChemCollective Virtual Labs online''' interface.

Open any web browser.

In the Google search, type '''ChemCollective virtual labs '''and press''' Enter.'''
|-
|| '''https://chemcollective.org/vlabs'''
||Click on the '''ChemCollective Virtual labs '''link that appears first on the page.
|-
|| Cursor on the page.

Point to '''Resources Type''': '''Virtual Labs'''.

||By default the main page opens with '''Resources Type''': '''Virtual Labs'''.

List of available topics are listed on the page.
|-
|| Click on '''Stoichiometry''' topic.
||Click on the down arrow next to '''Stoichiometry''' topic.

A menu with the available virtual lab experiments opens.
|-
|| Click on the yellow coloured '''Go''' button.

Cursor on the page.

|| In the''' Glucose Dilution Problem '''activity, click on the '''Go''' button.

'''Glucose Dilution Problem, virtual lab''' page opens.

|-
|| Point to '''Stockroom''' and '''Workbench 1'''.
||Page has two panels: '''Stockroom''' and '''Workbench 1'''.
|-
|| Point to the '''Solutions''', '''Glassware '''and '''Tools''' tabs.
||In the Stockroom, we have '''Solutions''', '''Glassware '''and '''Tools''' tabs.

|-
|| From the '''Stockroom''', click on '''1M Glucose Solution. '''

Cursor on the panel.

Cursor on the Panel.

Point to the information
||From the '''Solutions tab''', click on '''1 Molar Glucose Solution. '''

100 mL of 1 Molar glucose solution is added to the Workbench.

Information about 1 Molar glucose solution is shown in the left panel.
|-
|| From the '''Stockroom''', click on the '''Glassware''' tab.

Click on''' Erlenmeyers'''.

Select 250 ml Erlenmeyer flasks by clicking on the plus button.
||From the '''Stockroom''', click on '''Glassware''' tab.

Select 250 mL '''Erlenmeyer flask''' by clicking on the plus button.

Drag and place the 250 mL flask at a convenient location.
|-
|| Drag the Glucose solution flask to the empty flask
||I want to transfer 1 Molar Glucose solution to an empty flask.

Drag the Glucose solution flask to the empty receiving flask.
|-
|| Cursor on the pop-up window.
||A pop-up window with 3 different modes of transfer appears.
|-
|| '''Slide Number 5'''

'''Precise Transfer'''
||'''Precise '''transfer mode is used to transfer precisely upto second decimal point.

Precise transfer mode can be used for transfer of both solids and liquids.

|-
|| Type 10.546 in the volume field. Click the on '''Pour''' button.
||I will transfer 10.546 mL of solution.

Type 10.546 in the volume field.

Click on the '''Pour''' button.
|-
|| Click on the X button on the right-side of the pop-up window.
||Click on the '''X''' button on the right-side of the pop-up window to close the window.
|-
|| Click on the receiving flask.

Cursor on the left panel.
||Click on the receiving flask.

The left panel shows the volume in the flask as 10.546 ml.
|-
|| Right-click on the flask.

Click the '''Remove Liquid '''option.

Point to the empty flask.

||Let us empty the liquid in the receiving flask.

Right-click on the flask to open the context menu.

From the menu, click the '''Remove Liquid '''option.

The flask is now empty.

|-
|| Cursor on the workbench.
||Now I will demonstrate '''Significant Transfer '''mode.

|-
|| '''Slide Number 6'''

'''Significant Transfer '''

||Significant transfer is used to transfer liquids from or to the glassware which hold a definite volume of liquid.

This mode is used when glassware such as pipette, burette or measuring cylinder are used to transfer liquids.

It can only transfer the maximum amount of liquid the glassware can hold.

|-
|| Click on the 10 ml Pipette from Glassware tab.
||I will select a 10 ml pipette from the '''Glassware''' tab on the left panel.
|-
|| Drag the 10 ml pipette to the Glucose stock solution flask.
||Drag the 10 mL pipette to the Glucose stock solution flask.
|-
|| Cursor on the pop-up window.

Click on the '''Sig Fig''' button.

||The pop-up transfer window appears.

Click on the '''Sig Fig''' button.

Notice the '''Withdraw''' and '''Pour''' buttons.
|-
|| Type 10.00 in the volume field. click on '''Withdraw''' button.

Click on '''X '''button to close the window.
||Since we are using a 10 ml pipette, type 10.00 in the volume field.

Click on the '''Withdraw''' button.

Click on the '''X '''button to close the window.
|-
|| drag the pipette to the receiving flask.
||Now drag the pipette to the receiving flask.

Again the transfer pop-up window appears.

|-
|| Type 10 and now click on the '''Pour '''button.
||Type 10 and now click on the '''Pour '''button.

Notice the error message in the pop-up window.

|-
|| Type 10.00 and click on the '''Pour '''button.
||While pouring, we need to type the decimal figures also.

So type 10.00 and click the '''Pour''' button.

Close the pop-up window.
|-
|| Cursor on the receiving flask,
||Now you can see 10 ml is transferred to the receiving flask.
|-
|| Right-click on the Pipette and select remove.
||To delete the pipette, right-click on the pipette and select '''Remove '''option.
|-
|| Right-click on the flask.

Click on the '''Remove liquid '''option.

||Again empty the liquid in the receiving flask.

Right-click on the flask, click on '''Remove Liquid '''option.

Now I will demonstrate the '''Realistic transfer '''mode .
|-
|| '''Slide Number 7'''

'''Realistic Transfer'''
||In realistic transfer mode, solutions are transferred by holding down the '''Pour''' button.

The longer the Pour button is held down the greater volume of solution is transferred.
|-
|| Drag the flask with Glucose solution on to the empty erlenmeyer flask.

In the transfer pop-up choose the '''Realistic '''option.
||Bring the flask with '''Glucose''' solution on to the empty Erlenmeyer flask.

In the transfer pop-up choose the '''Realistic '''option.
|-
|| Text Annotation.

Press and hold the '''Hold to pour''' button to transfer the solution
||Press and hold the, '''Hold to Pour''' button to transfer the solution.

Release the button once the desired amount of liquid is transferred.
|-
|| Cursor on the pop-up window.
||The amount of solution transferred is shown in the pop-up window.
|-
|| Click on the '''X '''button to close the window.
||Close the pop-up window.
|-
|| '''Slide Number 8'''

'''Summary'''

In this tutorial, we have learned about 3 different modes of transfer in Vlabs.

Precise transfer

Realistic transfer

Significant transfer
||With this we come to the end of this tutorial.

Let us summarize.

|-
|| '''Slide Number 9'''

'''Assignment'''
||As an assignment,

Practice the transfer of solutions using various transfer modes demonstrated in the tutorial.
|-
