Supply and disposal

Safe storage – active and passive

There can be very different technical and documentation requirements for the active and passive storage of flammable liquids. How will you store your chemicals? It is best to determine how substances will be stored before setting up your work stations or your laboratory. The following overview highlights some important aspects to consider with regard to active and passive storage.

Active storage

Flammable liquids are stored in open or unsealed containers.
Chemicals are filled or transferred in or on the safety storage cabinet.
Your safety storage cabinet is actively connected to your processes. It is a storage location – and also a workplace.

Passive storage

Liquids or solids are stored in sealed containers.
No filling or transferring takes place in or on the cabinet.
Your safety storage cabinet acts only as a storage location.

Proactive work safety

DÜPERTHAL safety storage cabinets for active storage guarantee that your work adheres to the regulations. Their design offers a firm foundation for efficient workflows. This enables us to offer you individual solutions, optimally tailored to your processes.

Your technical advantages

Optimum management of liquids during supply and disposal.
The risk of an accident due to overfilling is minimised.
Effective and monitored object and air curtain extraction when filling – as well as ventilation at every cabinet level – ensure the risk of a potentially explosive atmosphere forming is reduced and health protection is increased.
The integrated earthing concept includes internal and external conductive surfaces as well as connection of all electrically conductive components with the potential connection on the cabinet body.

Your economic advantages

Decentralised storage with media available directly at the workplace makes work easier and saves time.
Safety processes are easy to set up and define, simplifying documentation in your risk assessment.
The explosion protection concept recommended in the GS certification can be incorporated in the explosion protection document and facilitates documentation.
Decreasing consumption of chemicals reduces purchase and disposal costs and protects the environment (carbon footprint).

VisiCon Waste Collection System

Collect flammable media centrally and flexibly
The VisiCon Waste Collection System is the perfect addition to DÜPERTHAL safety storage cabinets for active storage. The system can be used to collect larger quantities of solvent wastes centrally at a single collection point, e.g. a DISPOSAL line safety storage cabinet, in accordance with the regulations. The VisiCon collection system is also characterised by its high media resistance. All components are conductive and prevent the formation of ignition sparks.

Maximum flexibility for a streamlined workflow

The system can be extended almost without limit and the modular concept can be adjusted individually for each process on site. The diverse connection options are suitable for funnel systems and HPLC connections, and can also be adapted to individual requirements. Thanks to pre-assembled, ready-to-plug-in connections, it’s easy to get started, enabling flexible workflows and more efficient work processes.

Your benefits

Secure collection of hazardous substances in accordance with TRGS 509 and minimisation of harmful gases and vapours (emissions) in the workplace.
Continuous earthing to prevent ignition hazards resulting from electrostatic discharges, in accordance with TRGS 727.
Higher efficiency, thanks to gathering waste from several work areas at a central location.
Process reliability due to defined workflows, additional channels for the disposal of solvents are avoided.
Approved explosion protection concept for simplified recording in your explosion protection documentation, as part of the risk assessment in accordance with TRGS 400.
Flexible connection to DÜPERTHAL system solutions for active storage.
The almost infinitely extendible modular system can also be integrated at a later stage.

Your advantages with VisiCon!

Efficient workflow in accordance with regulations
Solvent waste is disposed of directly at the workplace, additional channels for waste disposal are eliminated.
Sustainable and flexible disposal system
The modular system can be optimally integrated into any work or laboratory situation and can be extended almost without limit.
Efficient and certified solution
The hazardous substances can be channelled from several systems/work stations to a certified safety storage cabinet.

Modular system

For a high level of media resistance, all metallic components are manufactured from high-quality stainless steel 1.4571. The hose system is made of electrically conductive PTFE-el and has a smooth finish to guarantee good media flow. The hoses are also wrapped in a spiral on the exterior for protection against mechanical stress.

Funnel systems
Safe disposal of hazardous substances via a funnel with a direct connection to the disposal container.

Direct connection of HPLC systems
Easy connection of capillary and media hoses thanks to a large selection of bench penetrations and adapters.

Distributors and smooth-walled hose systems
The distributors and hose systems are available in various diameters – the right solution for every viscosity.

Prevention of ignition hazards
All components are electrically conductive and the system for the earth connection is prepared in line with TRGS 727.

Tested and certified disposal system
The media are collected in system solutions with special explosion-protection devices, e.g. DISPOSAL BENCH line, in accordance with TRGS 509 and TRGS 727.

Profile system – flexible and robust
The flexible profile system is the alternative to bench penetration and can be used as a standing surface, for example, for HPLC systems.
