Hamilton [MPE]²

The Hamilton [MPE]² — Monitored Multi-Flow Positive Pressure Evaporative Extraction Module — consolidates solid-phase extraction (SPE) steps into a single device. Hamilton states it works as a standalone device (US only) and also integrates onto the deck of their automated liquid handlers.

At a glance

Positive pressure	0–100 psi
Evaporation temperature	RT +5 °C – 60 °C
Reagent dispensing	50 µL – 2 mL
Labware	Many SPE cartridges, plus 24-, 48- and 96-well plates
Plate height	Most filter/collection plate heights up to 114 mm
Revolution control	Initialise, set pressure, set temperature, set duration, read status

Instrument features

• Dual elevator — the two plates adjust independently, within the plate-height range given above
• Restricted flow principle — maintains a steady top-to-bottom flow direction through the plate, rather than letting flow take the path of least resistance
• Active monitoring — the unit monitors both pressure and evaporation temperature for consistency across experiments

Optional modules

The base unit can be extended:

• Reagent Module — dispenses up to seventeen different reagents across one or multiple columns. Hamilton states it can dispense 1 mL across a 96-well plate in under one minute
• Evaporation Module — controls and continuously monitors temperature while removing excess liquid, for steps such as sorbent drying, within the evaporation temperature range given above. Includes a portable needle drying module

Which of these are fitted determines what a method can usefully ask for: setting an evaporation temperature on a base unit without the Evaporation Module has nothing to act on.

Supported methods

• Init — initialise the module before use
• Set pressure — set the working positive pressure
• Set temperature — set the evaporation / sorbent-drying temperature
• Set time — set the duration for the step
• Get status — read the unit’s current state, so a schedule can wait on it

Parameters are set and then the step runs, so a schedule can stage pressure and temperature before the plate arrives.

Integration

Revolution talks to the [MPE]² over a serial connection.

Prerequisites

• The unit must be cabled to the Revolution host and its COM port known before the device is initialised.
• The optional modules your method depends on must be physically fitted — see above.
• Filter and collection plate heights must be within the dual elevator’s stated range.
