Written Scheme of Examination (WSE) for Pressure Reactors
At Asynt, we collaborate with laboratories, research facilities, and industrial sites to develop and implement a compliant Written Scheme of Examination (WSE) for pressure reactors that aligns with regulatory standards and best practices.
- Tailored WSE Documentation: We assist in drafting custom WSEs suited to your specific pressure reactor setup and laboratory requirements.
- Expert Consultation: Our specialists guide you through the regulatory framework, ensuring your pressure vessels comply with PSSR 2000, PED, and other relevant standards.
- Pressure System Safety & Compliance Audits: We assess your existing safety procedures and provide recommendations for improvements where necessary.
- Training & Best Practices: Our team offers guidance on safe pressure reactor operation, inspection procedures, and preventive maintenance.
- Seamless Integration with Asynt Pressure Reactor Systems: Whether you are using high-pressure reactors, gas systems, or laboratory autoclaves, we ensure your WSE is perfectly aligned with your equipment’s specifications.
Asynt is a trusted provider of high-quality laboratory pressure reactors, with extensive experience in pressure system safety and compliance. Our team ensures that your laboratory remains fully compliant, giving you peace of mind while working under high-pressure conditions.

A Working Scheme of Examination (WSE) is a legally required document for pressure vessels under UK regulations, such as the Pressure Systems Safety Regulations 2000 (PSSR 2000), as well as international standards including the Pressure Equipment Directive (PED) in the EU.

This document sets out:
- Inspection Schedules: Specifying how frequently your pressure reactor should be examined to ensure ongoing safety and compliance.
- Safe Operating Limits: Defining the maximum allowable pressure and temperature for your system.
- Risk Assessment & Hazard Identification: Addressing potential risks, including over-pressurisation, corrosion, or mechanical failure.
- Testing & Certification: Ensuring your pressure vessel meets regulatory compliance for laboratory and industrial applications.
- Record-Keeping & Traceability: Providing a detailed log of maintenance, inspections, and pressure tests for auditing and compliance purposes.
Failure to have a properly documented WSE can result in legal non-compliance, safety risks, and operational downtime – all of which can be avoided with Asynt’s expert support.
