easyFILL Automated Dosing Station

Automated Dosing Station

easyFILL frees the operator from reagent addition and dilution by automating these steps, with the additional benefits of reducing their exposure to concentrated acids and ensuring consistency of the process. easyFILL frees the operator from reagent addition and dilution by automating these steps, with the additional benefits of reducing their exposure to concentrated acids and ensuring consistency of the process.

Aleviating Bottlenecks in Sample Preparation Workflow

Sample preparation is a central part of elemental analysis and includes several manual and time-consuming steps. Reagent addition into digestion vials or vessels is a tedious and often unpleasant process that, in high throughput labs, requires a significant amount of time.
The easyFILL Automated Dosing Station addresses these latter challenges using a single platform that ensures the automation of reagent addition and dilution, finally ensuring superior workflow for the lab and higher safety for the operator.

  • Benefits

  • Less Handling Time

  •  Enhanced Safety

  • Consistency

  • ● High Flexibility

easyFILL is fully controlled by a touch screen terminal with customized software. For routine processes the operator simply recalls a stored method with the type and volume of reagents as well as the number of positions in use. Availability of the reagents in the bottles and the waste volume are tracked by the software, so that the operator knows when it is time to refresh a reagent bottle or empty the waste tank. Moreover the software integrates a guided procedure to calibrate the pump, in just few minutes.


The dispensing accuracy of the easyFILL pump ensures great reproducibility, while the handsoff approach and the use of high-purity PTFE for all the acid lines avoids risk of contamination. Moreover, the automatic cleaning of the lines, built into the sequence, avoids contamination when different reagents are dosed.


easyFILL offers great flexibility with a wide variety of racks to accommodate most digestion vessels and even two sets simultaneously such as two ultraWAVE racks. The system handles up to six reagents at a time (such as HNO3, H2O2, HCl, HF) matching most application needs. easyFILL comes into play before the digestion for acid addition and after for pre-dilution or for acidification of the digested solutions. Moreover, easyFILL is compatible with ICP autosampler racks to avoid additional handling.


Handling of concentrated acids and the use of pipettes under a fume hood could expose the operator to the acids. easyFILL automates these processes and avoids acid handling. The built-in exhaust further enhances the safety of operations by diverting any acid vapours to the lab extraction system.


Less operator time, improved workflow, enhanced safety

The task of manually adding reagents occupies valuable time of the operator, limiting lab productivity and the ability of the chemist to accomplish other tasks. easyFILL automates these steps, reducing the operator time to just a few seconds.

Your Lab Partner for Improved Workflow and Enhanced Safety


easyFILL is available for different type of digestion vessels, racks and ICP autosampler racks.

SK-15 easyTEMP

SK-15 rotor

Regardless of the samples you’re trying to digest, the SK-15 High-pressure rotor is always an effective option to simplify your journey from sample to analysis, even with hard-to-digest samples, reactive samples or large sample masses. The SK-15 is a high-pressure and high-temperature rotor with a capacity of up to 15 PTFE-TFM vessels of 100 mL.

MAXI-44 easyTEMP


Many laboratories routinely process high number of samples, such as soils, sediments and aqueous samples. The MAXI-44, featuring up to 44 PTFE-TFM vessels of 100 ml, perfectly matches these requirements, providing high productivity, reliability and superior ease of use. The MAXI-44 finds its natural fit in all laboratories requiring to process large samples batches.



The MAXI-24 High Performance (HP) and high throughput rotor was designed with double pressure limits and greater capacity than other high throughput rotors. It processes increased volumes of sample and a wide variety of matrices within a single rotor-based platform. Quick-assembly vessels are closed with a simple hand-tightening, improving your daily productivity.
