MBI | Rules & Code of Conduct

Trainings and Workshops

1. Users must attend trainings prior to accessing any microscopes in the facility. At this moment, hands-on training is only available for MBI staff/students/MBI collaborators.

2. For operation of microscopes, 1-2 hours hands-on training will be organized based on the following requests:

a) Regular Training Request

- Trainings would be conducted on a regular basis, provided by our core staff or vendor.

b) On-demand Training Request

- Students/staff who wish to be trained have to gather a total of 5 MBI staff/students/MBI collaborators to initialize an on-demand training.

- Simply submit the filled Training Request Form to Microscopy staff and we will organize a training as soon as possible.

- Email endorsement from PI is acceptable if the PI is on oversea trip.

c) Waiting List Training Request

- Students/staff who are unable to gather 5 MBI staff/students/MBI collaborators for On-demand training will be enrolled in Waiting List training.

- Microscopy Core staff will conduct trainings for users who have submitted their request regardless of the total number of trainees available in the Waiting List training Request within 2 weeks from the date of forms submitted.

3. MBI PIs do not need to gather 5 staff/students to initialize On-demand training for themselves. Individual training will be organized for MBI PIs upon request.

4. Users who fail to attend the registered training session without prior notice or valid reason will not be able to attend similar training for one month from the supposed date of training.

5. Regular workshops will be organized for those who wish to learn more about microscopes.

Booking and Cancellation

1. There are 2 groups of microscope users in Calcium booking system:

a) Novice - Users can only book allocated microscopes from 9am to 10pm, Monday to Friday

(Novice users for Biostation CT can register their slots available 24-hourly, Monday to Friday.)

b) Autonomous - Users can book the allocated microscopes at all time.

2. The following flow chart denotes the requirements for promoting from Novice to Autonomous

The criteria to pass the test that promotes access right from Novice to Autonomous:
