KNOWLEDGE marking CE stands for Communauté européenne, European Commission. CE marking of products allows for free movement of goods within the European Union without any additional formalities and certificates. It is not an official mark. The responsibility for application of the CE mark lies with the manufacturer in the European Union or the importer. Further obligations for distributors are specified in various Directives. There is no “separate” European Directive for laboratory equipment and laboratory fa- cilities. Examples for applicable EU Directives and regulations for laboratory equipment: • Low Voltage Directive 2014/35/EU • Electromagnetic Compatibility Directive 2014/30/EU • Machinery Directive 2006/42/EC • Pressure Vessels Directive 2014/29/EU • Pressure Equipment Directive 2014/68/EU • Regulation on appliances burning gase- ous fuels 2016/426/EC • Regulation on in-vitro diagnostic medical devices (EU) 2017/746 • Regulation on medical devices (EU) 2017/745 • Other directives and regulations, e.g. Measuring Instruments Directive or Reg- ulation on protective equipment Depending on the intended purpose of the laboratory equipment, the person responsi- ble (manufacturer/importer) determines the intended use and specifies the selection of the applicable directives or regulations with the relevant standards, ideally European standards that have been harmonized. With the CE Declaration of Conformity, the person responsible declares that the prod- uct complies with the applicable standards. The CE mark is affixed to the product or alternatively to its packaging if the product is too small. Detailed instructions for use or operating instructions are a part of the re- spective product. If a directive or regulation is applicable, the CE mark must be affixed; otherwise the product may not be sold.

KNOWLEDGE KNOWLEDGE Sterilisation of laboratory equipment made of plastics Autoclaving Recommended autoclaving protocol 20 minutes at 121 °C (2 bar), according to DIN EN 285 Autoclaving (steam sterilisation) is defined as the destruction or irreversible inactivation of all reproducible microorganisms under exposure to “saturated steam at a minimum of 120 °C.” (DIN 58946-1, 1987). DIN EN 285 specifies a minimum exposure time (te) of 20 minutes (killing time and safety margin) at a sterilisation temperature of 121 °C. For the correct sterilisation procedure, including biological safety (DIN EN 285), please contact your hygiene specialist. Prior to autoclaving plastic labware, ensure that no soiling or residual contamination remains on the equipment. Otherwise, the residual con- tamination will bake on solidly during the autoclaving process. Even substances that have no effect on the plastic at room temperature can still lead to destruction of the plastic during the autoclaving process. Additionally, microorganisms might not be killed effectively if they are protected by the residual contamination. Notes on autoclaving • Containers with screw tops or stoppers must be open during autoclaving to allow for pressure equalisation ➡ Autoclaving of a closed container will lead to the deformation or destruction of the container • Plastic labware should be stood upright on a level surface during autoclaving to avoid shape deformation. ➡ Plastic labware should not be laid on its side during autoclaving • No mechanical stresses should be present during autoclaving ➡ For example, do not stack items • Do not autoclave any container that contains residual contamination or even rinsing agent • Not all plastics are resistant to steam sterilisation! For example, polycarbonate loses its tensile strength ➡ Mind the temperature limits for the plastics ➡ Autoclavable products are identified with a “121 °C” symbol in this catalogue The surfaces of some plastics can be attacked by chemicals present during autoclaving, which can cause persistent clouding. Some transpar- ent plastics can absorb minute quantities of steam, which can lead to reversible clouding. This clouding disappears upon drying, which can be accelerated through the use of a drying oven. Note! For gas sterilisation, dry heat, and prior to heating in a microwave oven, all closures and stoppers must be removed as well. Heating plastics in microwave ovens Many plastics are suitable for use in microwave ovens. More accurate information can be obtained from the Table “Physical Properties of Plastics” on page 26. In this connection, it is important to be mindful of the chemical and temperature stability of the various plastics, and to ascertain whether the particular article and its contents are compatible with the given temperature. When aggressive acids, alkalis, or sol- vents are to be heated, the use of fluoroplastics is recommended. It is very important to provide for adequate ventilation (e.g., fume hoods). Prior to the use of plastic labware in a microwave oven, the closures and stoppers must be removed from the apparatus. 28

A flat bottom can be needed, if the vials have to run down minimal in the device. • Bevelled headspace rim resp. flat DIN beaded rim A bevelled headspace rim can be required for some special closure systems (Perkin Elmer).

This new screw cap is made of a material of highest chemical resistance (TpCh260). In order to prevent the medium from being contaminated in any form, the cap does not contain any colorants or plastic pigments. The pressed-in silicon seal is coated with PTFE on both sides for highest demands on chemical resistance. The matching pouring ring is made from the same material and guarantees non-dripping and safe handling. The Premium Cap is characterized by its temperature resistance ranging from -196°C to +260°C. Due to the high temperature range, this cap is suitable for many sterilization methods such as autoclaving or dry sterilization. The ”Premium Cap“ meets all requirements of both US Pharmacopoeia (USP Class VI) and European Pharmacopoeia (EP). With Retrace Code (Batch Certificate of Performance via Internet).

DURAN PURE Premium Screw Cap with Lip Seal GL 45, DURAN Group / IDL Thanks to the highly resistant material (PFA), the DURAN PURE Premium screw cap with lip seal GL 45 is perfectly suited for chemically and thermally demanding processes. Due to the very high temperature resistance, it is ideal for difficult sterilisation processes such as hot air or dry heat sterilisation and depyrogenisation at 260°C. The material used com- plies with the FDA requirements (FDA 21 CFR Section 177.1550) and the USP (USP Class VI plastics -121°C). This means that this screw cap is particularly well suited for applica- tions in the pharmaceutical, chemical, and food industry. The Der DURAN PURE Premium screw cap made of PFA is equipped with a cone, i.e. an integrated lip seal, and accord- ingly does not need any additional seal to keep the bottle tightly closed. Furthermore, this feature makes the cap easy to clean and to sterilise. Product features: • Material: PFA; can be used for all GL 45 threads • Produced and packaged under cleanroom conditions class 7 • Excellent temperature resistance from -196°C to +260°C • Ideal for dry heat sterilisation / depyrogenisation • Very high chemical resistance • Complies with FDA 21 CFR Section 177.1550 & USP class VI • Easy to clean and to sterilise • No colour additives (leaching out of colourants excluded) Continued on next page
