MicroCal VP-ITC

GE Microcal VP-ITC

 

Summary

The MicroCal VP-ITC (Isothermal Titration Calorimeter) unit directly measures heat evolved or absorbed in liquid samples as a result of mixing precise amounts of reactants. A spinning syringe is utilized for injecting and mixing of reactants. The user inputs the experimental parameters (temperature, number of injections, injection volumes) and the computer carries out the experiment. Origin® software is then used to analyze the ITC data using fitting models to calculate reaction stoichiometry (n), binding constant (KD), enthalpy (ΔH) and entropy (ΔS).

To avoid damage or contamination, researchers must provide their own Hamilton 0161714 syringe for loading sample solutions.  The instrument must be reserved in advance, and various rules apply.  Reserve time using "Booked".  Reservations do not require approval.

The instrument is located in 1238 Hach Hall.  Enquiries should be directed to Steve Veysey.  Phone 515-294-5805 (office).  NOTE: The Microcal ITC is now serviced and supported by the Malvern company.  The weblink is: http://www.malvern.com/en/products/measurement-type/microcalorimetry/default.aspx.

FY'18 Rates

The instrument is to be used by students and other researchers.  Significant training is required, including sucessful completion of several tutorials and lessons before you will be authorized to use the instrument.  Staff will NOT provide methods development assistance for this instrument, but will direct you to internet-based ITC resources. The hourly rates are listed below.  NOTE:  There is a minimum charge of $10 for each use of the instrument.

User Category Instrument Charge Staff Assistance
ISU researchers $2.70 $30
Non-ISU academic researchers $4.05 $45
