Automated Filling Station

PeriFlex™ is an automated, peristaltic pump based filling instrument that tackles simple and complex filling tasks with ease

High performance peristaltic pump

Periflex™ is an automated filling station based on the succesful Beeline range of robotic sample processors. At the heart of the system is a high-resolution peristaltic pump drive which delivers precisely metered quantities of liquid into any tube or vessel that will fit on the instrument. Pipetting layouts can be readily created to cope with any array of racks or tubes.

Ideal for sterile applications

Being based on a peristaltic pump ensures that the entire fluid path is easily removable for sterilisation. A special locating arrangement ensures that the probe remains sterile when installing it back on the instrument.

Accurate for a wide range of volumes

The pump is designed to take tubing with a range of internal diameters (typically 0.5mm up to 3.2mm) making it suitable for a wide range of volumes and liquid types. This enables you to optimise the pumping performance to match your particular requirements.

Automatic calibration

For applications requiring a higher degree of accuracy, an automatic self calibration check can be performed to compensate for minor differences in tubing performance.

Flexible software

PeriFlex is supplied with software specifically designed for filling tasks. Although powerful, the PeriFlex software can be set-up for very simple routine operation. The number of runtime parameters required can be controlled so that operation of the instrument is simplified further.

Variable volume batches

For greater flexibility, up to 4 batches with different pipetting requirements can be made to run consecutively without user intervention. This is particularly useful when needing to fill different sized tubes with the same liquid. Furthermore, the volumes dispensed can also be controlled by an external spreadsheet enabling individual tubes to receive different volumes based on a calculation. For example, when disolving compounds, the volume of solvent added could be based on the mass of the compound in the vial to achieve a predetermined concentration.

Septum piercing option

A special high-torque Z-drive option can be fitted in conjunction with a septum piercing needle arrangement to allow filling of tubes with rubber stoppers such as Vacutainer® tubes (Becton Dickinson), Vacuette® tubes (Greiner) and chromatography vials.

Security shield

A perspex security shield can be supplied (optional) to keep the work platform clean and also to provide additional safety when the septum piercing option is fitted.
