Manual handling of acids with digestion vessels – a health and safety concern?
Operator exposure to acid fumes especially with working with multiple acids is a possible concern for health and safety when adding acids to digestion vessels. In addition, the task takes valuable operator time that limits laboratory productivity and the ability of the chemist to accomplish other tasks.
Any sample preparation for elemental analysis requires the addition of reagents and the handling of these reagents, even if ultrapure, is a key factor in achieving lower detection limits and ensuring reliable quantification limits. Apart from potential contamination from pipette tips and dirty glassware, another consideration is the potential for the presence of the analyst to contaminate the reagents from the use of cosmetics and the presence of watches, rings, bracelets, and other jewellery.
Implementation of an automated dosing system such as the Milestone easyFILL acid dosing station from Analytix can effectively overcome both safety concerns and reagent contamination as it controls direct addition of reagents in most digestion vessels and vials without exposing the operator to the reagents. It provides better acid dispensing capability, and a superior analytical blank value compared to the manual bottle top dispensing method by removing analyst contamination and human error.
The system provides automated dosing of up to six acids (including HF) and reduces operator time to just a few seconds. The dosing compartment and all parts in contact with acids are manufactured from anticorrosive materials and the system is controlled via a Microsoft Surface GO with customised software that has pre-stored rack configurations. For routine processes, it is possible to create a library of customised methods with the type and volume of reagents and the number of vessel positions.

63757pr@reply-direct.com Versatile autoclaves for superior steam sterilisation
Priorclave’s QCS range of autoclaves is one of the most versatile and cost- efficient steam sterilisers available. What sets the QCS range apart is that the three standard cylindrical chamber sizes of 100, 150 and 200 litres provide 20% more loading capacity than sterilisers of the same capacity. This extra space enables the QCS range to accommodate taller or more usual items, avoiding the need to invest in larger, heavier and more costly rectangular chambered sterilisers.
From simple cycles to fully featured multi-programme operations, Priorclave’s exclusive Tactrol®3 control unit allows unrivalled flexibility and allows users to focus on other tasks, secure in the knowledge that it will automate the entire sterilising process from start to finish perfectly.
Feature packed as standard, every autoclave in the QCS range features a quick-seal single-action door fitted with both thermal and pressure locks, whilst utilising Priorclave’s patented door retention device, altogether these prevent accidental openings at load temperatures above 80°C and pressures above 0.2bar. Non-tip shelves ensure all media remains secure throughout the loading and unloading process. Biomaster ™ anti-bacterial silver nano-technology is incorporated into external surfaces providing effective defence against bacteria and fungi, including MRSA. This coating also reduces the risk of microbial growth and cross-contamination. Every QCS features low external surface temperatures whilst in use. Inside the chamber, automatic free-steaming greatly improves temperature distribution by encouraging air removal. Powerful fans also blow cold air over the autoclave vessel reducing cooling times. The Tactrol®3 also enables a delayed start if required to protect loads sensitive to media volume loss.
Optional features include load-sensed processed timing, where an internal probe ensures exact sterilisation times. Whilst Pre- and Post-cycle vacuum ensures air removal from difficult loads. When combined with pulsed free-steaming, this achieves excellent steam penetration.
