Minimise risk with calibration and validation
M
icrosep offers a variety of high-quality services to ensure weighing instrumentation delivers continued accurate and precise results to meet various industry standards. The range consists of individual weights, weight sets and related balance calibration and validation services. Test weights The weight portfolio covers OIML or ASTM test weights for the performance checks of weighing equipment from 50mg to five tons in all accuracy classes, with or without a calibration certificate. Weights are ideal for the calibration, verification and routine testing of balances and scales. Due to their high quality, test weights are ideal as primary mass standards to calibrate other weights of lower class accuracy, particularly in mass laboratories. Efficient routine testing CarePac sets are greatly beneficial as they fully support routine testing of balances with external weights. They offer a convenient and cost-effective way to limit the risk of working outside of specified process tolerances. By just using two test weights at 5% (repeatability) and 100% (sensitivity and eccentricity) capacity ensures efficient balance routine testing in accordance with USP chapter 41 and GWP. CarePac sets are supplied with a calibration certificate and professional weight-handling accessories. The three sizes of CarePac sets enable you to test balances of up to 8kg weighing capacity. Benefits of calibration In combination with calibrations performed by technicians, and technical balance features, routine testing is a convenient way to professionally monitor balance performance. Microsep's calibration and validation services ensure adjustments to factory specifications; accurate, reliable and traceable results; operation to regulatory requirements; optimisation of equipment settings, and certification documentation.

Thermo’s proven reliability in ULT freezing makes it ideal for storage of Covid-19 specimens
L
ong term storage of all COVID-19 specimen types must be done at temperatures below -70°C as specified by the WHO and CDC in recent publications. The proven reliability of the Thermo Scientific FDE Forma -86°C Ultra Low Temperature Freezer range makes it the ideal choice when you need to increase sample storage capacity due to the COVID-19 emergency. This series is offered with a 5-year standard warranty from the manufacturers.
Forming part of the Standard Performance (STP) family, Thermo Scientific Forma FDE Series ultra-low temperature freezers feature four upright models that maximise storage capacity from 30 000 up to 60 000 2mL vials. The FDE series is a sustainable and reliable solution with ultimate sample security and operational savings for every laboratory. In addition, this series has a wide range of accessories to facilitate your sample storage. Features and benefits of this range • Energy reduction saves on electricity, up to 25% • Heat output reduction saves on HVAC need/continued cost • Lower noise allows for “in lab” equipment positioning minimising footsteps, below 53dBA • Sets the baseline for manufacturer’s warranty coverage – five years • Recovers cabinet temperature 20% faster after opening the door.1 • Natural hydrocarbon refrigerants reduce system operating stresses • The new H-drive Information Center (HIC) combines easy to read temperature with simple capacitive touch buttons in a 5.6” display • Four capacities (300, 400, 500 and 600

Temperature dry-well calibrator with light, compact design
W
ika’s innovative CTD4000 series calibrators have been designed for on-site applications as well as for the severe conditions of the naval and marine sectors. Their ease of use and their compact and practical design make them unbeatable in industrial processes where the calibration of the temperature measurement systems is essential for the control of the process and the quality of the final product. Special attention is paid to reduce weight and size, and to reinforce robustness by using an aluminium body as well as aluminium and stainless steel for many internal parts.
With the available standard inserts, the calibrators are versatile and can be easily adapted for the calibration of temperature probes with the most common diameters. Customer-specific inserts and bores are available on request.
