20 Compact Heating and Cooling


The powerful Huber Ministat range offers precise temperature control from -40°C to 200°C and their compact size makes them idea for use in fumehoods or on crowded benches.


Each of the three Ministat models feature the new CC Pilot controller with a choice of three control options; basic, exclusive and professional. Units may be easily upgraded from one control level to another via a user installed electronic upgrade.


The CC Pilot controller’s bright, clear, LCD colour screen displays internal, process and set point temperatures in large format enabling easy viewing from across the lab, with the option of a real time graphical display. Safety information such as over-temperature setting, set point limits, bath level indicator, alarms and pump pressure/speed can be displayed simultaneously.


All Ministat units feature a powerful variable speed pressure/suction pump that can heat or cool objects either in the internal bath or externally, such as reaction vessels or block. The small bath volume and high power means exceptionally rapid heating and cooling rates are achieved. Optional displacement inserts reduce the bath volume by approximately 50% amplifying this effect. All models have ‘Active Cooling Control’ that allows cooling even at the maximum working temperature.

New Syringe Filters


As part of the development of the KX+ brand, Kinesis is pleased to announce the launch of KX+ Syringe Filters. A premium quality range, KX+ Syringe Filters are available in a wide choice of membrane, pore sizes and formats to address all common filtration applications. Manufactured using a fully automated process under an ISO Quality Management System, KX+ Syringe Filters do not compromise filtrate quality. The filters exhibit excellent chemical compatibility, contain minimal extractables and have leak free connections. This ensures minimal instrument downtime and analytical column lifetime is extended.


Circle no. 562 Stop Time-Wasting Cleaning


Available only with Fritsch Cutting Mills: all grinding parts can be removed for cleaning in just a few seconds without tools – unbeatable fast, simple and efficient. This makes them ideal, time saving assistants in the comminution of fibrous and tough materials, plastics and heterogeneous mixture of materials and for sample preparation for RoHS and WEEE analysis.


Practical applications include: comminution of toys – to verify lead; comminution of PET-plastic bottles/PET pressings – for analytical assessment of the recycled material for the production of higher value products; comminution of all kinds of nuts – for example to verify the contamination with mycotoxins; comminution of natural rubber – for analytic assessment of the crude materials, before they can be used for further processing; comminution of leather – for chemical analysis and for analytical monitoring; and comminution of wood - for the analysis of matured timber in regards to heavy metals, arsen and PCP/PCB.


Advantages of the Fritsch cutting mills include; especially simple operation for fast work; unmatched ease of cleaning thanks to patented quick opening facility; optimum airflow for particularly fast grinding and secure protection against clogging; more stable running and low wear due to the patented double cone bearing of the rotor; exceptionally long service life through use of replaceable and fixed knives; unique grinding chamber geometry: minimal dead space and progressive cutting geometry between the rotor and the fixed knives – for faster and simpler operation; and grinding parts with different cutting geometries and materials - perfectly adjustable to individual applications.


Fritsch Cutting Mills are available in different configurations – for each application the perfect Mill. LAB PRODUCTS Circle no. 565 LAB PRODUCTS Circle no. 564


Isolated Island Achieves Health Self-Sufficiency


At the Princess Elizabeth Hospital on Guernsey, two cobas®


linked to MODULAR PRE-ANALYTICS, from Roche are helping the hospital’s laboratory increase efficiency and become more self-sufficient.


With 183 different assays, Roche offers the largest menu of tests available on an automated SWA (serum work area) platform, thus providing an ideal solution for the Guernsey laboratory.


The new system has brought benefits for staff and patients alike. Previously, different platforms meant multiple blood draws – one serum tube for each of the analysers, typically three to four per patient – to try to get the work done as quickly as possible. The new streamlined workflow makes the phlebotomist’s job easier and means less discomfort for the patient.


One of the critical aspects for a laboratory in a remote location is reliability. With 99.9% of serum and urine samples being processed by the automated system, this was a major factor in the lab team’s decision. “The cobas®


e-link remote diagnostics, which allows Roche technicians to


interrogate, diagnose and often resolve issues without having to fly in to the site, was also seen as a benefit for our island laboratory”, added Nigel. Despite their special circumstances, Nigel and his staff know that with Roche’s superior technology, reliability and support, they are not cut off from the world.

Reproducible and Easy Measurement of Large Sample Areas


The accurate measurement of large sample areas is now faster, simpler and more convenient with the introduction of the Carl Zeiss Axio CSM 700 confocal microscope. The new microscope visualises surfaces three- dimensionally in true colour at high resolution to enable the precise measurement of 3D microstructures surface roughness.


Ideally suited to materials research, quality inspection and routine applications, The Axio CSM 700 offers a motorised scanning stage


with a 150 x 150mm travel range and performs topographical measurements at a rate of more than 100 frames per second. Height information is reliably detected even on relatively ‘soft’ surfaces with step heights from 20 nm up to the millimetre range and the depth of focus has previously only been offered by scanning electron microscopes (SEMs).


Scanning stage control is integrated into the Axio CSM 700 software and a ‘Mosaic’ function allows large sample areas to be captured with a stitching algorithm that eliminates transitions in the final image. The large sample area allows parameters such as roughness and wear rate to be determined with a higher statistical reliability. The easy-to-use software provides numerous analysis options, including the measurement of roughness, evaluation of layer thickness and particle analysis. Additional functions, such as a newly programmed filter, facilitate and improve image processing.
