17 User-Friendly Software for Quantitative Force Measurement
The microscopic manipulation of biological specimens, individual cells and cell components is becoming increasingly common in life science laboratories around the world. Now, the launch of the PALM MicroTweezer Force Measurement module from Carl Zeiss, which eliminates the need for additional hardware and time-consuming adjustment and calibration, means that the technique can be adopted by many more users.
The Force Measurement module not only controls the manipulation of microscopic particles with the PALM optical tweezers, but also enables the quantitative measurement of forces relevant to many life science disciplines, visualising the data in real-time. The new module offers users a flexible and user-friendly interface to the software’s functionality, which will enable a large degree of freedom in experimental design and test configuration.
The module also enables the use of the PALM MicroTweezers system for pure specimen manipulation as well as for position detection and quantitative force measurement. This means that direct comparisons may be made between experimental results and data from the literature. Calibration routines for the characterisation of the optical tweezers are performed automatically and archived together with all experimental data and images.
The Force Measurement module is supplied together with an FM StarterKit containing the FluidCell component, which permits fast and easy sample preparation. The PALM MicroTweezers and Force Measurement module can be combined with various solutions from Carl Zeiss, including the PALM MicroBeam and Colibri light source.

New Cost-Effective Refrigerated Incubator
Fisher Scientific, Inc has introduced the Thermo Scientific Heraeus BK 800 refrigerated incubator for storage of valuable substances at, or below, ambient temperatures. With a compact footprint of 0.3m2
and a large capacity of 220 L, this unit provides an innovative space-saving solution for the laboratory.
This easy-to-use, CE certified unit has obtained best-in-class energy efficiency ratings, making it environmentally friendly and cost-effective. Providing a homogenous, stable environment with superior temperature uniformity ranging from 3 to 40°C, the Heraeus® and media storage, microbiological testing and biochemical oxygen demand (BOD) protocols.
BK 800 incubator is ideal for a wide range of applications, including sample
With two internal electrical sockets, the Heraeus BK 800 refrigerated incubator can accommodate stirrers, shakers and lights as well as other equipment that can be time controlled for defined cycles. An impact-proof interior with rounded edges makes the unit easy to clean, minimiing the risk of contamination from unwanted microorganisms. Furthermore, all internal shelves and supports are easily removable to aid the cleaning process. The inclusion of a reversible door enables left or righthanded opening and the door gaskets are simple to replace. With an easy-to-use soft touch control panel, user-friendly operation is facilitated and the unit is easy to set-up within the laboratory, using the built-in rear wheels.
The Thermo Scientific Heraeus BK 800 refrigerated incubator is a cost-effective unit, providing fullyreproducible, high quality results every time. LAB PRODUCTS Circle no. 548
ADVERTORIAL Are your ECDs legal ?
Electron Capture Detectors contain a radioactive source and so are controlled by legislation.
Cambridge Scientific
Instruments Ltd (CSI) is licensed to provide a range of services designed to help users of these devices remain within the law.
It is a legal requirement that the detectors are "wipe tested" to detect radioactive contamination of the surface at intervals of between one and three years depending upon local regulations. CSI supply a convenient wipe test kit containing full instructions and materials to perform the test. The test samples are then sent to CSI for analysis and report.
ECDs can be contaminated by dirty samples and require cleaning, the legal requirements mean that this must only be carried out by suitably qualified personnel in a registered laboratory. This cleaning is another of the services CSI can offer.
CSI is also able to dispose of detectors that are no longer required, safely, efficiently and legally. Circle no. 549
