Is the Reactor-Ready range resistant to acids? Summary In general, Reactor-Ready is suitable for use with acids, but it is each customer’s responsibility to assess their particular application, carefully considering any risks. Reactor-Ready has been specially designed to be robust and to have a reduced risk of leaking compared to other systems, but no equipment is indestructible, and safe working practices must be adhered to, with the Reactor-Ready carefully maintained, to minimise the risk of leaking/corrosion. Materials of parts expected to come into contact with chemicals (‘wetted parts’) We manufacture our vessels and other glass accessories from borosilicate glass 3.3. The piston (bottom outlet valve tap) in a Reactor-Ready system is PTFE and glass-filled PTFE, with FEP-encapsulated O-rings. The O-ring between the vessel and lid is also FEP-encapsulated, and is held in place by a PTFE support collar. The stirrers and Pt100 probes are PTFE-coated also. The main body of the stirrer guide is made of PTFE too, with borosilicate glass and PEEK/PTFE parts. Acid resistance of wetted parts Borosilicate glass 3.3, PTFE and FEP all have excellent acid resistance. We have a technical data sheet on the borosilicate glass; you can download this from our Technical Information Downloads web page. For PTFE and FEP, you can double check compatibility with your particular acids using chemical resistance tables/data available online. System maintenance and safe working practices Although our systems have good chemical resistance, it’s important to regularly check the condition of all parts (particularly seals such as O-rings) – these can be damaged in other ways, such as scratching by chemical particles, wearing by moving parts, or being made brittle through exposure to extreme low temperatures. We recommend you purchase the relevant maintenance kit (part number RR121150 for standard Reactor-Ready or order two for Reactor-Ready Duo; the part number is RR210100 for Reactor-Ready Pilot), as this contains the common consumables – so you can replace items as soon as any deterioration is observed, to help avoid leaks or downtime. If you look after your reaction system (maintaining good sealing), you can minimise the escape of chemical vapours that could then damage less chemically resistant parts (e.g. the stirrer drop-in coupling made from stainless steel). Always wipe away any chemical spills immediately and avoid exposure of Reactor-Ready systems to strong vapours such as HCl, as continued exposure to even low levels of chemicals can cause corrosion to metal and/or plastic components.
