Holders for general imaging

FEI single tilt holder

Standard sample holder available for the Tecnai microscopes and the ATEM.

FEI double tilt

The holder has a beta-tilt of about +/-30°. The specimen cradle and clamping material (hexring and anti-twist washer) are made of beryllium to minimize unwanted X-ray signal from the holder.

Gatan double tilt beryllium holder

The holder has a beta-tilt of about +/-30°. The specimen cradle and clamping material (hexring and anti-twist washer) are made of beryllium to minimize unwanted X-ray signal from the holder. The holder has a Faraday-cup at the tip for possible measurement of the beam current (with an external picoampermeter).

Holders for EDS analyses

Gatan double tilt beryllium holder

The holder has a beta-tilt of about +/-30°. The specimen cradle and clamping material (hexring and anti-twist washer) are made of beryllium to minimize unwanted X-ray signal from the holder. The holder has a Faraday-cup at the tip for possible measurement of the beam current (with an external picoampermeter).

FEI double tilt

The holder has a beta-tilt of about +/-30°. The specimen cradle and clamping material (hexring and anti-twist washer) are made of beryllium to minimize unwanted X-ray signal from the holder.

Holders for heating experiments

DENSsolution Wildfire single tilt heating holder

MEMS-based holder for heating up to 1300°C. It is a single tilt holder which is also suitable for EDS.

Protochips Fusion Select double tilt heating holder

This MEMS-based holder has 6 contacts, which allows for heating, electrical biasing/measuring and the combination of both. It has beta-tilt capabilities up to about +/- 20° and is suitable for EDS. The chips can be heated up to about 1200°C.

Gatan 652 In double tilt heating holder

Classical furnace heating holder which is suited for standard 3mm samples. The heating furnace is made from Inconel and suited for heating in oxidizing gas environments (ETEM) up to about 800°C. This holder is not suited for EDS because of the furnace design.

Gatan 652 Ta double tilt heating holder

Classical furnace heating holder which is suited for standard 3mm samples. The heating furnace is made from tantalum and ONLY suited for heating in non-oxidizing gas environments (ETEM) up to about 1000°C. This holder is not suited for EDS because of the furnace design.

Special Holders

DENSsolution Climate gas and heating holder

The MEMS-based closed-cell holder offers the possibility of gas environments up to atmospheric pressure (1bar). Up to three gasses can be used simultaneously. Additionally, it offers temperature control up to 1000°C. The setup is also equipped with an residual gas analyzer to detect reaction products.
