EM-Tec variable tilt and pre-tilt angle holders

EM-Tec variable tilt and pre-tilt SEM holders are useful for imaging specimens under a pre-tilt angle without having to tilt the SEM or FIB-SEM stage. With these holders you can image previously mounted specimens on standard SEM pin stubs or Hitachi SEM stubs at pre-set angles or any chosen angle. Tilt holders are particularly useful for table top SEMs without specimen tilting facilities or for standard SEMs where high tilt would interfere with the polepiece or with detectors in the chamber. Sometimes, pre-tilt holders are used to get full tilting from the SEM stage. With a pre-tilt 45°  holder, the SEM stage only needs to be tilted another 45° to get a full 90° specimen tilt.

EM-Tec tilt holders include:

  • EM-Tec TV12 mini variable tilt mount allows a 0-90° angle in a small specimen mount and are available with an SEM pin stub (#12-000241) or M4 thread (#12-000347). The specimens need to be mounted on the tilting platform of this compact holder. Side engravings at 0, 30, 45, 70 and 90 degrees on the tilting platform assist in setting the desired tilt angle.
  • EM-Tec TV25 larger variable tilt holder allows a 0-90° angle for SEM specimen stubs or SEM specimen holders up Ø38mm. Larger SEM stubs can be mounted, but tilting can be limited, depending on the SEM in question. Compatible with both pin or Hitachi M4 threaded stubs or holders. Available with SEM pin stub (#12-000248) or M4 thread
    (#12-000348)
  • The EM-Tec GS1 0(#12-000110) is a swivel vice which covers a full 180° angle and can also be rotated with the specimen stub. This is the optimum holder for imaging cross sections at any desired angle.  The swivel head size without clamping screws is only 16 x 16 x 14mm. The specimen is held by two clamping screws and the swivel head can be locked in place with these screw. Made from gold plated brass.
  • EM-Tec PS15 (#12-000211) swivel pin stub mount. The head of the mount is attached to the pin via a swivel hinge which allows for 90 degrees tilting each way. Excellent mount for SEMs without tilting facilities or when random tilt angled are needed. When the desired tilt angle is set, the top is secured with a socket cap screw. Top diameter is 15mm and height above pin is 15mm.
  • EM-Tec P36 (#10-002236) fixed angle 36° tilt holder for Zeiss SEM pin stubs. Used to pre-tilt specimens 36° for Zeiss CrossBeam  FIB systems.
  • EM-Tec P38 (#10-002238) fixed 38° tilt holder for FEI pin stubs. Used to pre-tilt specimens 38° for ThermoFisher Scientific / FEI Dual Beam FIB systems.
  • EM-Tec P45 (#10-002245) most popular  45° pre-tilt holder with pin for standard and Zeiss SEM pin stubs.
  • EM-Tec P45M (#10-002246) popular 45° tilt holder with pin for Hitachi M4 SEM stubs or M4 threaded holders.
  • EM-Tec H45P (#12-000345) popular 45° tilt holder with M4 for standard and Zeiss SEM pin stubs.
  • EM-Tec H45 (#12-000346) popular 45° tilt holder with M4 for Hitachi M4 SEM stubs or M4 threaded holders.
  • EM-Tec P70 (#10-002270) fixed 70° EBSD tilt holder with pin for SEM pin stubs and pin stub-type specimen holders.
  • EM-Tec P70M (#10-002274) fixed 70° EBSD tilt holder with pin for Hitachi M4 SEM stubs and M4 threaded holders.
  • EM-Tec H70P (#12-000370) fixed 70° EBSD tilt holder with M4 for pin stubs and pin stub-type specimen holders.
  • EM-Tec H70 fixed 70° (#12-000371) EBSD tilt holder with M4 for Hitachi M4 stubs and M4 threaded holders.
  • EM-Tec 45° multiple SEM pin stub holders can be found on: EM-Tec multiple pin stub holders
  • EM-Tec 45° multiple M4 stub holder can be found on: EM-Tec multiple Hitachi M4 SEM stub holders

All the holders are precision machined from vacuum grade aluminium and include set screws and allen key.
For using the pre-tilt and variable tilt holders on JEOL SEMs, you can find the JEOL pin stub and JEOL M4 on the  SEM stub adaptors page.
