Shaking up Microtitre Plate Incubation Stuart®
sample volumes in microtitre plates and microfuge tubes. The chamber of the Stuart®
announces the SI505, a combined incubator shaker specially designed to reduce sample evaporation and provide fast, optimised mixing of very small SI505 can accommodate up to four standard microtitre or deep-well plates, or two racks holding 0.2, 0.5 or 1.5ml micro tubes.
The high-speed orbital shaking action is ideal for effective mixing of samples in even the smallest vessels, while a state-of-the-art microprocessor enables accurate, reproducible control of temperature between ambient +7ºC and 60ºC. The versatile integrated timer can be set from 1 second to 9 days. Removable water reservoirs increase the humidity in the chamber of the SI505, minimising sample loss due to evaporation. Tests have shown that at 78% humidity, samples incubated at 37ºC for 24 hours in lidded microtitre plates lost on average only 6% of the total sample to evaporation, based on a 200µl sample in each well. The warm air feed from above also prevents condensation of sample on the lid, eliminating the risk of light scattering by liquid droplets when the plate is to be read in a plate reader.
The new compact benchtop SI505 shares several proven features with the unrivalled Stuart® SI500 shaking incubator. A retractable stainless steel platform
provides easy access to samples, a digital display shows the independently controlled temperature and speed, and USB connectivity allows long-term monitoring of the incubator temperature via a PC. As with all Stuart® technology as standard, to minimise microbial contamination.

Bath Range Extended
The latest addition to the Huber refrigerated bath circulators range offers temperatures down to -55°C. The CC-508 thermostat is ideally suited for controlling the temperature of externally closed applications or for thermoregulating objects directly within the bath. Operating within the temperature range of -55 to +200°C, heating powers from 3kW and cooling powers from 1.5kW @ 0°C are available. The powerful variable speed pump guarantees an optimum circulation of 33l/min and 0.9 bar (pressure side) and 22l/min and 0.4 bar (suction side). The CC-Pilot controller offers professional features to meet the highest application demands.
Housing is made of stainless steel with a thermoregulated lid to prevent the formation of ice or condensation. The bath volume is 5L and is fitted with a tap on the front for easy draining.

A New Mobile Multiparameter System from WTW
Making your Measurement Life Easier: photoLab® The PC software photoLab®
6100 VIS and 6600 UV-VIS, e.g.: meters Data Spectral Data spectral is a helpful tool for convenient data management with WTW's
photoLab® 6000 Series spectrophotometers. This software package allows a safe handling of the original data taken with photoLab®
• GLP-compliant administration of data reading instrument ID and using the complete user administration as set in the photoLab®
• Data transfer from photoLab® spectrophotometers to PC for post-processing and graphical elaboration in the user environment, e.g. with LIMS or spreadsheet
• Export of scans into spectra software for a consistent display and evaluation of multiple spectra • Matching several photometers with methods, profiles and software updates.

WTW GmbH from Weilheim, Germany, announces its new MultiLine®
The new sensors are based on the proven WTW SenTix®
handheld measuring instruments with IDS intelligent digital sensors. pH / ORP sensors and TetraCon®
conductivity cells. However, the IDS sensors convert the raw signals into digital signals which are insensitive against interference and can be transferred over large distances, particularly with pH sensors.
For optical DO measurement, a completely new IDS probe, the FDO®
925 has been developed. It
employs a factory-calibrated sensor cap, thus making further calibration unnecessary.
Three new meters are available:
The Multi 3410 is a one-channel multi meter for users who measure different parameters only sequentially. The Multi 3420 can simultaneously measure, display and store two, the Multi 3430 three parameters.
All meters have waterproof (IP 67) housings and keypads.
