Diestro’s Autosampler Cap Pierce, developed by JS Medicina Electrónica S.R.L., received the Argentine Good Design Seal No. 7819 in 2026.
The system enables automated sample collection directly from capped primary tubes, reducing handling steps and exposure to air. Integrated with the Diestro V4r electrolyte analyzer, it features up to 45 positions to automate routine sample processing.
The distinction was presented on September 24, 2026, at Palacio Libertad in Buenos Aires.
What is the Diestro Autosampler Cap Pierce?
The Autosampler Cap Pierce is an automated loading system designed to work with primary tubes.
Its main feature is its ability to pierce the tube cap and collect the sample directly from its original container, without the need for a prior manual transfer.
This allows a routine laboratory task to be performed with fewer operator interventions.
The system accommodates adult and pediatric primary tubes, with or without caps, and provides up to 45 positions.
What does the Cap Pierce system bring to the laboratory process?
Automation is not only about processing a larger number of samples. It also means reviewing each stage of the process and identifying where unnecessary intervention can be reduced.
By working directly from the closed primary tube, the Autosampler Cap Pierce can:
- reduce sample handling;
- minimize the need to transfer the sample to another container;
- limit exposure to air;
- automate the loading and processing of successive samples;
- reduce manual tasks for the operator.
Reduced exposure to air is particularly important when working with measurements such as ionized calcium and pH, which are sensitive to the sample’s pre-analytical conditions.
Cap Pierce and the Diestro V4r electrolyte analyzer
The Autosampler Cap Pierce can be integrated with the Diestro V4r, the analyzer in the V4 family that expands electrolyte measurement to include pH and TCO₂.
The V4r measures Na⁺, K⁺, Cl⁻, Ca²⁺, Li⁺, pH and TCO₂ and provides calculated parameters such as Anion Gap, calcium corrected to pH 7.40 and HCO₃⁻.
The addition of the Cap Pierce provides an automated sample-loading option and allows a solution to be configured according to the needs and workflow of each laboratory.
Why is design important in laboratory equipment?
For Diestro, medical technology design goes beyond the appearance of the instrument.
It also encompasses the relationship between the equipment and the operator, the path followed by the sample, component integration, manufacturing, and the ability to transform a specific laboratory need into a solution that is simple to use.
In the Autosampler Cap Pierce, this approach guided the design, engineering and production process.
The ability to operate directly on a closed tube is the visible result of numerous decisions that take place behind the product: from the piercing mechanism to its integration with automated sample processing.
What cannot be seen is designed, too.
Argentine Good Design Seal No. 7819
For Diestro, this distinction recognizes the integration of technology, functionality, biosafety, manufacturing and identity within a development carried out in Argentina.
“Receiving the Argentine Good Design Seal encourages us to continue developing solutions in Argentina that are designed around the real needs of laboratories. Congratulations and thank you to the entire Diestro team who made this recognition possible,” said Ian Sarcansky, General Manager of the company.
Argentine development for laboratories around the world
At JS Medicina Electrónica S.R.L., we have been developing and manufacturing laboratory technology under the Diestro brand since 1991.
Today, our electrolyte analyzers and related solutions are marketed in more than 65 countries.
The development of the Autosampler Cap Pierce continues this journey by combining engineering, local manufacturing and accumulated knowledge of laboratory workflows.
The Argentine Good Design Seal represents a new recognition of this work and an incentive to continue developing solutions that make laboratory processes simpler, safer and more efficient.
When design improves the process, innovation becomes visible.
