Press
Spex 3636 X-Press®
35-ton (31.8 metric ton) hydraulic laboratory pellet press that accepts 13 mm, 31 mm, 35 mm, and 40 mm pellet die sets. Automatic and fully programmable. Ideal for repetitive pressing of sample pellets for XRF, IR, and other analytical techniques.
Features:
- Automated, programmable laboratory press.
- Presses samples in minutes and accepts all standard die sets.
- Safety interlock and automatic pump shut-off safety valve ensure safe operation.
- Compact bench top system.
- Can be operated manually as a simple motorized press whose functions are under direct user control.
- Programmable LCD touch screen interface. Allows the user to enter final pressure desired, time to hold at the final pressure, and interval to return back to zero pressure.

Training
Before onsite training
MCC registered users should pass the following EHS online trainings prior to onsite training:
- Yale EHS Laboratory Safety Training
- Yale EHS X-ray Safety Training, required for XRD and XRF users only.
- Finish the online X-Ray Generating Equipment Safety Program. Make sure to submit the X-ray Safety Quiz to EHS online at the end of the training.
- After onsite training at the core, fill the X-ray Training Signoff Sheet (download only on core website) and email to Shuhang Pan for signature.
- Email the signed signoff sheet to EHS.
- Download Request Form for Radiation Monitors and fill in the following info:
- List Shuhang Pan as Authorized Principal Investigator.
- Check Gamma/X-ray Source box and specify Cu as the source.
- Check X-ray diffraction box and list location as Room A119, 810 West Campus Drive, West Haven.
- Check right or left box to indicate which hand is to be most exposed to X-rays.
In the List Location next to X-ray Diffraction, put the following address:
Room A119Energy Science Center (ESC) II810 West Campus DrWest Haven, CT 06516
- Email the Radiation Monitor form to EHS.
Course sessions
The core operation training course for each instrument includes three sessions.
- Introduction, covering an introduction to theory and demonstration of core operation by the lab manager.
- Practice session I, scheduled within one week. Users will practice core operations under lab manager supervision.
- Practice session II, also scheduled within one week. Users are expected to be able to work independently at the core as judged by the lab manager.
Important note
- Users must schedule two practice sessions within one week, otherwise they need to retake two sessions.
- Users should use the facilities at least once a month, otherwise they should contact the core for practice again.
