LabRAM II

The Resodyn LabRAM II mixes by ResonantAcoustic Mixing (RAM) — low-frequency acoustic energy driven at resonance, with no impeller or other mechanical means inside the vessel.

That last point is the reason to choose one. Nothing enters the sample, so there is nothing to clean between materials and nothing to shed into the mix — which is what makes it usable for powders, pastes and materials an impeller would contaminate or simply fail to move.

Specifications

Resodyn publishes the following for the LabRAM II, beyond the At a glance table above.

Technology	Second-generation ResonantAcoustic Mixing (RAM)
Observation	Acoustic housing with strobe lighting, to observe mixing phases and progress

Resodyn describes RAM as combining the efficient power generation of resonance with the effects of low-frequency sound energy. The strobe lighting is a practical touch: at mixing frequencies the contents are a blur, and the strobe is what makes the phase visible to an operator.

A LabRAM II H variant is offered for hazardous environments. The figures above are for the LabRAM II.

Supported methods

• Mix — run a mix

That is the whole control surface. Mixing parameters — acceleration, duration, profile — are set on the instrument or in Resodyn’s own software; Revolution decides when a mix runs.

Integration

Revolution needs two serial connections for this device, not one:

Property	Purpose
Labram COM Port	Serial port for the mixer itself
Motor Controller COM Port	Serial port for the motor controller

This is the setup detail most likely to catch someone out. Resodyn describe the LabRAM II as fully integrated with no separate control component — but the Revolution integration still addresses a second controller on its own port. Both need to be identified and configured; getting one right and leaving the other unset will not work.

Prerequisites

• Both serial ports must be known and configured before the device is initialised.
• The mix parameters the schedule relies on must already be set on the instrument.
• Payload must be within the stated 1 kg capacity.
• At up to 100 g of acceleration, vessels and their closures must be secured as Resodyn requires — this is a mixer that will move anything that is not properly retained.

If you need more of this instrument driven from a schedule, get in touch — the driver is extended on demand.
