Q. What is the difference between Model ChemLab Professional and Standard editions?
A: Model ChemLab Pro includes the Lab Wizard tool which enables instructors to run, edit, and create lab simulations while the Standard edition enables students only to run lab simulations.

Q. What's the difference between a UDL and a DLL simulation file?
A: There are two types of lab simulation files: a) User-Defined Lab (UDL) files with a *.udl extension can be created and edited by users with a Lab Wizard tool (available with Pro edition only), and b) pre-programmed simulation plug-ins with a *.dll extension that cannot be created or edited by users but are supplied with Model ChemLab.

Q. What is the Lab Wizard?
A: The Lab Wizard is a Model ChemLab tool used to design chemistry lab simulations (available with Pro edition only). Although ChemLab comes with a variety of lab modules, you need not limit your work to these pre-fabricated experiments. The Lab Wizard will translate your experiments into ChemLab modules called User Defined Labs (UDL's) by asking you to supply it with documentation, chemical data and reaction formulas.

Q. What lab simulations are included with Model ChemLab?
A: Model ChemLab comes with a range of pre-designed lab experiments for general chemistry at the high school and college level. Users can expand upon the original lab set using ChemLab's LabWizard development tools, thus allowing for curriculum specific lab simulation development by educators. These user designed simulations combine both text based instructions and the simulation into a single distributable file.

Q. What platforms does Model ChemLab support?
A: Model ChemLab is available for Windows 8/7/Vista/XP/ME/98/95, Windows 2000 &  NT version 3.51 and higher, and Mac OSX

Q. Does ChemLab run on Windows 8?
A: Yes, ChemLab will run on Windows 8. But, you will need to run Windows in desktop mode to run ChemLab. You will also need to run the installer from desktop mode.

To run desktop mode touch or click the desktop tile to switch to your desktop. The desktop tile is usually at the bottom left hand corner of your tile collection and has 'desktop' written on it.

Note: chemlab will not run on Windows RT; this is a special version of windows for tablet devices which utilizes ARM architecture.

Q. Is Model ChemLab networkable?
A: Yes. Simply install Model ChemLab on your server. Then add a Windows shortcut to the ChemLab application (chemlab.exe) installed your server on each of your networked computers.

Q. Is Model ChemLab suitable for distance learning?
A: Yes. Model ChemLab is used for distance learning, virtual schools and home schooling.

Q. Why can't I get the beaker to pour?
A: Pouring and decanting involve selecting a piece of lab equipment, positioning its left side over the receiving container and selecting the decant button from toolbar or decant/pour menu item from the procedures menu or from the right-mouse-button context menu. If the pouring object is not directly over the receiving object, the contents will be suspended. Note: liquid is transferred first in this process to allow separation.

Q. How can I get a printout of the lab Introduction and Procedures?
A: There are print options settings for selecting which documents are printed. Goto the Options menu and select from the printer options the documents you wish to print, prior to printing. The default is to print the observations and lab window.

Q. Is Model ChemLab available on a CD?
A. Yes. Model ChemLab is available both on CD and Online.

Q. Where do I find the ChemLab serial number?
A. You will find the serial number in the About ChemLab dialogbox.

Q. How do I upgrade ChemLab?
A. You can obtain the ChemLab upgrade online from the upgrade page. You will need your serial number from the ChemLab About Box. You can upgrade both the Spanish and English versions. You can also upgrade from English to Spanish if you wish (if you do so you should unistall the English version before running the Spanish Install). The Update page will also give you a Password that is need for the install program, you should write this down.

Q. Install program fails, no error message?
A. For Windows 7/Vista/XP/2000/NT, only the Administrator or user with Administrator rights can install software. Log out and back in as an administrator and try install again.

Q. Downloaded Installer fails when opened in Web Browser under Vista?
A. If you are having problems running the downloaded installer for ChemLab on Vista, do the following:

  1. login as an administrator in Vista - only administrators can install software on Vista and XP.
  2. Download the install file and save it on hard drive.
  3. Right mouse click on install file and use the menu option "Install as Administrator"

Q. When performing a titration, how do I get the buret to work?
A. There are a number of reasons why your buret may not work:

  • The buret must be correctly positioned above the container into which you are titrating; it cannot overlap.
  • The buret must have some contents.
  • You must open the stop-cock using the titration dialog and that dialog must correspond to the buret you are using. If you label the buret; the label text will appear in the Titration dialog's title.
  • The container you're titrating into must not already be full.

    It should look like this:


Q. The conductivity meter doesn't work; conductivity value is always shown as 0.00?
A. You need to
combine the conductivity meter with the container with your solution to obtain a measurement.

  • Select both the Conductivity meter and container with solution you wish to obtain a measurement from.
  • Right mouse click in the selection rectangle then select the "Combine" menu from the pop-up context menu.
  • Conductivity meter should appear to be combined with the container.
  • Use the remove menu option to remove the conductivity meter from container.

    It should look like this:



Q. I cannot find the filter in ChemLab?
A. The Filter is the
'Buchner Funnel' menu option in the equipment menu. You can add it to an Erlenmeyer flask by selecting the flask and using the Buchner Funnel menu option (right-mouse-click context menu). You can remove it by doing the same again; this will display a dialog box that allows you to place its in contents into another container. You can also just use the Tool Bar (Buchner Funnel) button with nothing selected; this will add a flask with a funnel already added.
