SCAT adapters for Justrite® HPLC disposal cans

Continue using existing Justrite containers effectively

In many laboratories across the United States, Canada and South America, Justrite HPLC disposal cans are already in place and firmly integrated into laboratory workflows. These robust containers provide a proven basis for collecting liquid laboratory waste.

In practice, however, the existing quick couplings do not cover every connection task—for example when several capillaries, tubing with different diameters, a SCAT exhaust filter or an additional manual filling point must be integrated.

This is where SCAT Americas Inc. adds value. Purpose-designed SCAT adapters, collectors and connectors create the defined interface between the existing Justrite quick coupling and the required SCAT components. The existing container system can therefore be expanded to match the application instead of replacing a disposal can that is already installed and fully functional.

Practical benefits

• Existing Justrite HPLC disposal cans remain in service.
• Capillaries and tubing are routed in a defined way and securely fixed.
• Depending on the existing coupling, SCAT exhaust filters, compact collectors or HPLC manifolds can be connected.
• Additional connection solutions for LISA and MARCO are available for compatible polymer/CPC couplings.
• Laboratories across the Americas receive suitable components and technical support directly from SCAT Americas Inc. (SCAT Lab Safety).
  
  

Why defined connection technology is critical

HPLC, UHPLC and LC/MS systems continuously discharge liquid waste through capillaries or tubing. If these lines are only placed loosely into a container opening or connected through improvised transitions, lines can slip, ports can remain open and solvent vapors can escape in an uncontrolled manner.

A professionally configured waste system therefore routes waste lines into the container through suitable connections. Unused ports on manifolds or modular connection solutions are closed with the specified blanking plugs.

When waste liquid flows into the container continuously, the displaced gas phase must be be able to leave the container in a controlled manner. This helps prevent back pressure and impermissible pressure build-up in the disposal system.

The waste lines are therefore routed in a closed manner, while the required pressure equalization takes place in a controlled and filtered way. The system is not hermetically sealed; it is vented in a defined way.

SCAT solutions for different connection tasks

Different SCAT solutions are available depending on the existing Justrite coupling and the intended application. The key selection question is: Which solution matches the existing coupling – polymer/CPC or stainless steel?

SCAT offers different adapters, collectors and connector solutions for Justrite stainless-steel and polymer couplings. Selection should therefore always be based on the existing coupling and the specific connection task.

Polymer or stainless-steel coupling: the connection must match

Depending on the model or customer-specific configuration, Justrite HPLC disposal cans are equipped with polymer or stainless-steel quick couplings. These variants differ not only in material, but also in connection geometry and seal design.

The SCAT adapter must therefore always be selected to match the coupling actually installed on the container. For clear identification, check the Justrite model number and the existing coupling before ordering. If this information is not conclusive, a photo of the coupling supports technical selection. This helps avoid incorrect orders and unsuitable connection combinations.

Filtered venting instead of an open container port

Many solvents used in chromatography are volatile and evaporate even at room temperature. At the same time, collecting liquid waste creates a need for venting: when waste liquid flows into the container, the displaced gas phase must be discharged in a defined manner.

The combination of a Justrite container, a suitable SCAT adapter and an appropriate SCAT exhaust filter enables defined liquid inlet routing and controlled, filtered venting. Volatile solvent vapors can be adsorbed in the exhaust filter, helping reduce the solvent load in laboratory air.

Manual waste input with the SCAT safety funnel MARCO

For manual input of smaller waste quantities, MARCO provides a separate filling point that can be closed in a defined way. The hinged lid with integrated seal supports safe handling, while the removable sieve retains solids such as magnetic stir bars.

For Justrite containers with a compatible polymer/CPC quick coupling, the SCAT safety funnel MARCO creates a separate manual filling point. With the matching Quick-Lock connection, the funnel can be disconnected from the container when required.

Check materials and chemical resistance for the specific application

Depending on the design, SCAT adapters, collectors and connectors are made from different chemically resistant materials. Electrostatic-conductive versions are also available for selected applications. The suitable configuration always depends on the specific laboratory application and the actual waste mixture.

Chemical resistance is not determined by the container material alone. The entire wetted path must be evaluated, including couplings, seals, adapters, fittings, tubing, capillaries and filter components. Electrostatic-conductive components perform their function only when they are properly integrated into a suitable grounding concept.

Safe operation starts with the correct configuration

For reliable operation, connection components should not be viewed in isolation. They should be selected and operated as an overall system. The following points are especially important:

• Select the adapter to match the existing polymer/CPC or stainless-steel coupling.
• Close unused ports on manifolds or modular connection solutions with the specified blanking plugs.
• Route capillaries and tubing without mechanical stress and secure them against unintentional pull-out.
• Check couplings, seals and lines regularly for correct fit and damage.
• Replace exhaust filters according to the specified service life and actual exposure.
• Check the fill level regularly and replace or empty the container in good time.
• Evaluate chemical resistance and electrostatic requirements for the specific application.
  
  
  

Conclusion: expand Justrite containers with SCAT Americas in a targeted way

Justrite HPLC disposal cans are an established basis for collecting liquid solvent waste in many laboratories across the Americas. SCAT Americas Inc. (SCAT Lab Safety) adds the required connection flexibility to these existing systems. With suitable adapters, collectors and connectors, capillaries, tubing, exhaust filters, HPLC manifolds and—for compatible polymer/CPC couplings—the LISA and MARCO systems can be connected.

This creates an application-specific expansion solution that preserves existing investments, makes laboratory installations clearer and supports a closed-routing, filtered-vented disposal process.
