38 Reliable Sterilisation of Coronavirus Particles
Exhaust air filtration in autoclave steam sterilisation is extremely important, especially in light of the current coronavirus epidemic. Tests show that the exhaust air filtration in Systec autoclaves reliably prevent hazardous aerosols from escaping during the autoclaving process.
Systec products filter exhaust air by means of an autoclavable sterile air filter inside a filter housing and a PT-100 temperature sensor. All air displaced from the autoclave is passed through the filter and, as a result, the microorganisms are retained in the filter. The filter is also sterilised ‘inline’ during the sterilisation process in order to inactivate the microorganisms contained in it. The temperature inside the filter housing is monitored by the PT-100 temperature sensor. During the heat-up and sterilisation phases, the condensate is retained in the pressure vessel and also sterilised safely. Exhaust air filtration and condensate sterilisation prevent any viruses or germs from escaping before the end of the sterilisation phase.
The filtering medium used by Systec GmbH is an autoclavable sterile air filter in the form of a PTFE membrane filter cartridge with a pore size of 0.2 µm. The filter cartridge is located in a pressure- resistant housing and can be replaced quickly at any time. The PTFE membrane is additionally protected by polypropylene nonwoven fabrics on the upstream and downstream sides. External support bodies and end caps made of a special, heat-stabilised polypropylene as well as internal support bodies made of stainless steel ensure exceptionally high thermal resistance and mechanical strength. The filters are monitored via a maintenance counter, with a replacement interval of 150 cycles.
To ensure a validatable filtration, the heating temperature of the autoclave is monitored throughout the process via the PT-100 temperature sensor (class A). At the same time, this sensor ensures that the filter cartridge is heated to a temperature that enables the safe inactivation of filtered particles. In the event of any deviation from the prescribed process sequence, the autoclave is put into a fault mode, which prevents the outflow of contaminated exhaust air. The integrated user management functionality prevents unauthorised access.

Survey Finds Quality Control is a Major Challenge in Clinical Labelling A survey conducted among global
healthcare companies by PRISYM ID, a leading provider of data-led label and artwork management solutions, shows that a fifth of them experience quality control issues with clinical labelling on a monthly basis. The survey, which included companies ranging from pharma to medical device manufacturers, found that 6% had quality control issues with labelling as often as once a week and 18% once a quarter. 20% experienced these problems annually and the rest were not sure.
The majority (69%) blamed human error for mistakes in label printing; while 29% cited printer failures, such as a mechanical issue. 18% put problems down to incorrect data in the labelling system and a further 12% cited incorrect data from a third party or ERP system. The most common methods of capturing errors were human inspection of every printed label (57%), followed by the use of an inspection system, such as an electronic vision system, and regular printer maintenance and cleaning, which were each cited by 47% of respondents.
With regard to plans for an electronic vision inspection system, nearly a third (31%) had this type of system and 12% planned to buy one. However, 33% did not intend to invest in this technology and the remainder were unsure about their company’s plans. When asked about the most important benefit of a vision inspection system, the majority of respondents (63%) cited detecting and reducing errors. This was followed by compliance and then speed and efficiency.
Warren Stacey, SVP of Sales at PRISYM ID, said: “Our survey shows that many respondents struggle to ensure quality control during the product labelling process, with a fifth of them experiencing problems once a month and a small proportion suffering issues even more frequently.
“Human error is cited as the major culprit and that is very worrying as many respondents rely on manual inspection processes. Given the legal and reputational implications of errors or omissions occurring on product labels, we believe automated inspection is essential. An automated vision system will continuously inspect labels for problems ranging from incorrect barcodes that cannot be read by the human eye, to poorly defined characters, or text that has been printed in the wrong place. This enables companies to manage risk in label production and ensure regulatory compliance.”

User-Friendly Support System for Laboratory Scale Reactions
The ReactoMate DATUM from Asynt is a high quality, dual-rod stainless steel and aluminium support system built to ensure the stability and safety of your lab reactor. Sturdy, yet compact, the ReactoMate DATUM support system can accommodate a wide range of reaction vessels from 100 mL up to 5000 mL. Designed with user-friendliness in mind, the ReactoMate DATUM support system incorporates a suite of innovative features. Changing a vessel supported by the ReactoMate DATUM is as simple as ‘Clip & Click’. The novel neck clamp allows fast changeover between reactor vessel sizes thereby enabling simple reaction scale-up, whilst the ingenious mounting mechanism ensures excellent stability and alignment every time.
The Reactomate DATUM support system is fully compatible with all leading brands of overhead stirrers and circulator heating/cooling systems. Designed by chemists for chemists, low-friction polymer bearings line both the overhead stirrer alignment chuck and the neck support to ensure smooth and easy operation.
Ideally suited for use within a benchtop fume hood, adjustable feet allow you to level the ReactoMate DATUM support system ensuring stability and security while you work. Each DATUM system is also supplied with a moulded drip tray that fits perfectly within the base of the support, for safely catching any drips and spills from the reaction vessel during draining. With a wide range of accessories and upgrades available, including drain manifolds and automation packages, the ReactoMate DATUM support system really is the perfect all-rounder for laboratory scale reactions.
