User Policies and Fees

Whether you’re a new user or an existing user who is planning new experiments, please contact usfor a free consultationto discuss your experimental needs, sample preparation, and options for imaging.

After the consultation, you can request training on an instrument, or you may choose to be assisted at the microscope by a staff member.

For select projects, we provide Imaging Service, where you can provide samples for imaging by CSMSR staff. Please consult with us to find out if this service is appropriate for your imaging applications.

Appointments for imaging service or training should be requested at least 7 days in advance.

Training

  • Training is provided for users who wish to use the microscopes independently.
  • Certified independent users are entitled to reduced user fees and 24/7 access to instruments on which they have been trained.
  • All training must be performed by core staff.

Reservations

  • For most instruments, reservations must be made at least 24 hours in advance, and no more than 7 days in advance.
  • There is a 1-hour minimum reservation time for most instruments. There is a maximum reservation time of 4 hours per day and 8 hours per week during peak hours (9 am - 5 pm, Mon.-Fri.). There is no maximum reservation time outside peak hours.
  • Reservations cancelled less than 24 hours in advance will be charged unless someone else can use the time; please ask users scheduled before and after you if they can use it. There is no charge for cancellation at any time due to illness. 

Safety

  • The core operates at BSL-1; all samples potentially containing pathogenic agents must be properly fixed.
  • Follow current Columbia and Shared Resource guidelines for COVID safety.

If your experiment requires an exception to any policy, please discuss it with the Technical Director.
