Introducing the PP3010T

Quorum Technologies launches new cryo preparation system for SEM and FIB/SEM.

Quorum Technologies is pleased to introduce the PP3010T: a state-of-the-art, highly automated cryo preparation system for scanning electron microscopy (SEM), FE-SEM and FIB/SEM. Building on the success of the market leading PP3000T, the new PP3010T combines the highest performance with unparalleled ease of use.

Cryo-SEM is the optimum preparation method for a wide range of “wet” or beam-sensitive specimens, including for lifesciences, foods, polymers, pharmaceuticals, oils, foams and many other materials.

At the operational heart of the PP3010T is the new gas cooled aQuilo cryo preparation chamber, which includes tools for specimen fracturing and manipulation as well as fully automatic sublimation and sputter coating. Gas cooling ensures unsurpassed thermal efficiency and - along with the SEM stage and cold trap which are also gas-cooled – gives an impressive system temperature capability of down to -190oC or lower.

Cooling works on a simple ‘fill once and forget’ principle, with the remotely positioned cooling dewar/heat exchanger typically giving runtimes of up to 24 hours between fills of liquid nitrogen.

To ensure optimum performance and simplicity of operation, the aQuilo preparation chamber is attached directly to the microscope - but with turbomolecular pumping and the SEM cooling systems conveniently mounted remotely from the microscope.

The PP3010T is controlled using a large intuitive touch screen panel PC mounted on the spacious Prepdek™ workstation, giving the operator instant access and control of all the key operating parameters, data logging and system diagnostics.

CCD images from the cryo system are displayed and can be recorded on the control screen and multiple viewing windows give unsurpassed visibility of the specimen and chamber interior. The Prepdek™ also houses the freezing system and a unique pumped storage tube for the cryo transfer device.

Installation to the microscope has also become easier with the introduction of a compact, single port interface (dependent upon microscope geometry).

Like all other Quorum Technologies products, the PP3010T comes with a generous three-year warranty and specialised support.

Max Planck Institute Martinsred installs Quorum PP3000T

The world famous German institute of biochemistry called Quorum Technologies' PP3000T system "well designed" and "easy to use".

Scientists in the department of molecular structural biology at the renowned Max Planck Institute of Biochemistry in Martinsred, Germany, used the PP3000T system as part of a study on cryo-electron tomography.

The PP3000T played a key role in the development of a new breakthrough technique that enables visualization of the interior of thick eukaryotic cells in their native hydrated state.

Dr Alex Rigort of Max Planck Institute said: "The PP3000T system is a well designed, easy to use system that enables an efficient transfer of cryogenic specimens for FIB processing. It is great in terms of stability and cooling efficiency. 

"The software interface and touchscreen that comes along with it is straightforward to use and gives you an excellent overview of the different system parameters in use".

Competition winner announced

Following our recent competition to find the best short application note and/or image series completed using Quorum Technologies preparation instruments, we’re pleased to announce we have a winner!

The winner is Guohui Lin, a senior electron microscopist working at the Experimental Centre of South China Normal University, located in Guangzhou, Guangdong Province.

His specimens were part of a study looking at the effects of anti-cancer medicine, using a Quorum Technologies K750X Peltier-Cooled EM Freeze Dryer and a Q150T ES Turbo-Pumped Sputter and Carbon Coater.

Living mammary cells were cultured on polystyrene plates and the cells infected with bacteria. The cells were then chemically fixed in 2.5% gluteraldehyde in a fridge for six hours. 

After this, the specimens were rinsed in changes of phosphate buffer and rapidly frozen in slushy liquid nitrogen, generated in the K750X. Specimens were then freeze-dried in the K750X for six hours.

The dried specimens were mounted on stubs and sputter-coated with platinum (Pt) using the Q150T ES. Observation and imaging was then carried out using a Carl Zeiss ULTRA55 Field Emission Scanning Electron Microscope (FE-SEM)..


The competition marked forty years since the launch of Quorum Technologies’ first sputter coating and critical point drying systems in 1971. Other image submissions will be available in the Image Gallery soon. Guohui's images above show tumour cells infected with bacteria, freeze-dried and sputter-coated.

Quorum Technologies Student Prize Winners 2011

Three students from the University of Brighton have received an award through this year’s Quorum Technologies student prize scheme, having demonstrated exceptional use of electron microscopy in their final year projects. Our student prize scheme, in partnership with the University of Brighton, is now in its fifth year and still going strong – attracting interest from undergraduates working in a range of scientific disciplines.

For the first time, students were able to use the impressive new scanning electron microscopy (SEM) instrumentation that was installed and commissioned earlier this year in the Image and Analysis Unit.

This year, three prizes of £200 were awarded for final year undergraduate projects that the judges felt had made particularly good use of electron microscopy. The winners were Oliver Kitt, Benjamin Thompson and Hamidullah Waizy, whose projects are detailed below.

The judges were impressed by both Hamidullah and Ben’s ability to quickly learn to work independently on the SEM and EDS, together with the quality of EDS analysis undertaken and the effective use of elemental quantification in their projects.

They were also impressed by Oliver’s use of the high magnification images (obtained using the new Carl Zeiss Sigma FE-SEM) to provide visual evidence to support novel scientific findings, which would not otherwise have been possible, and was thus clear evidence of the important contribution SEM made to the project.

The prize is held within the University’s Image and Analysis Unit in the School of Pharmacy and Biomolecular Science and awarded on an annual basis.
