Microscopy & Microtechniques 61 Customised Cryo-Stage Enables AFM Users to Study Surface Properties Over an Extended Temperature Range
Linkam Scientific Instruments, have been chosen by JPK Instruments to supply a customised version of one of their cryo-stage systems to enable surface properties to be studied over an extended temperature range. Bringing their technologies together has enabled JPK to offer cryo-stage capability for their NanoWizard®
AFM systems. This means AFM users may now study surface property changes as a function of temperature over the range of -120°C to +220°C.
Head of Applications at JPK, Dr Heiko Haschke, describes the background to the development starting with the need as defined by JPK’s users. “The goal of the CryoStage product development at JPK instruments was to offer a versatile heating and cooling platform in one single piece of equipment. One of the main challenges is to design a stage for heating and cooling the sample while simultaneously performing atomic force microscopy (AFM) experiments. In addition, a controlled gas and ice free environment chamber needs to be guaranteed. Having set itself the target of a temperature range of from below -100°C to above +200°C, we were able to customise Linkam’s cryo-technology and obtain sample cooling to -120°C and heating to +220°C.”
Asked why JPK chose Linkam’s technology, Dr Haschke said: “The main alternative to the Linkam stage technology was for us to design a completely new product. However, we could significantly speed up the development by using the well-known and respected products from Linkam. As a result, after careful project planning, JPK Instruments selected Linkam’s technology and no other commercial equipment was evaluated. The main benefit of the Linkam stage was that it was a completely finished product on the market with almost precisely the ranges and specifications JPK Instruments needed, e.g. temperature stability of +/- 0.2°C. Linkam was also known to some employees at JPK Instruments who had good experience working with Linkam in the past. High-resolution AFM on a stage with cryogenic nitrogen pumps required some adjustments on the stage support in order minimise temperature drift. The adjustments were only possible due to the good Linkam technical support. In addition, the ergonomic, user-friendly control of the Linkam stage gave the product a modern finish.”
42058pr@reply-direct.com New Digital Microscope and Scanner Introduced
Laboratory and scientific equipment supplier, Medline Scientific, are pleased to announce the launch of the new Precipoint M8 Digital Microscope & Scanner. Manufactured in Germany, this modern piece of digital microscopy technology allows laboratories to scan slides (fully or partially) and create screenshots within 60 seconds.
With its own software, the Precipoint M8’s unique Live-Stitching feature quickly connects individual images taken at the resolution of your chosen objective (20x or 40x) to form single full-screen pictures, making your work easier and faster. You can flawlessly zoom through slides with this feature and the automated x-y stage, enabling you to annotate and measure your findings in the largest field of view possible at any position and magnification.
The Precipoint M8 also allows you to access and operate your work remotely where you can connect, share and discuss findings with colleagues and specialists around the world. Using a recommended touch-screen computer, the Precipoint M8 can give you fantastic results at the touch of your fingertips.

Jenoptik Completes Portfolio of Microscope Cameras
From September 2016, the PROGRES GRYPHAX®
KAPELLA,
RIGEL and PROKYON cameras will complete Jenoptik’s USB 3.0 product series, making it an attractive option for scientific use.
The new microscope cameras in the PROGRES GRYPHAX®
series
have been developed specifically for scientific applications in difficult lighting conditions. They are equipped with the latest CMOS sensor technology. With this development, Jenoptik has a
USB 3.0 camera portfolio with which every microscope can be upgraded to become a modern, digital workspace.
Scientists working with poorly illuminated or weakly transmitting samples will benefit from the wide-ranging capabilities of the CMOS sensors used. The high level of quantum efficiency and the considerable dynamic range, coupled with very low noise, are properties that set new standards. Active sensor cooling for exposure times of up to two minutes is no longer required.
The PROGRES GRYPHAX® KAPELLA is a sensitive color camera for challenging samples
and lighting conditions. It offers scientific users a new level of image dynamics and richness of detail. The PROGRES GRYPHAX®
RIGEL is the monochrome counterpart to the KAPELLA
and is the most sensitive camera in the entire portfolio. The PROGRES GRYPHAX®
PROKYON camera, the flagship of the PROGRES GRYPHAX
range, combines the best properties of all the models. It is the perfect all-round camera, capable of dealing with all aspects of microscopy through its image resolution of between 2.3 and 20.7 megapixels. Jenoptik is thereby continuing to invest in microscanning and color co-site sampling technologies. True colors can now be determined at speeds never previously achieved.
The operating software included is tailored precisely to the requirements and workflows of the user. With its especially short operating paths, the multifluorescence tool facilitates work in such applications. The software can be installed quickly and is operated in the same way on different computer operating systems such as Macintosh, Windows and Linux OS. Use is intuitive and therefore simple, giving users maximum flexibility when it comes to upgrading their microscopes.
