Thanks for that Sebas, it's still difficult to say because it's a translation into English "bench scale" could be a poor translation for a "bench-top scales/balance" which would change it completely.
However, having said that, if I had to choose, I'd go with Liz's suggestion, it's the most likely IMO.

I think "the correct reproducibility of the step on the chosen bench scale" indicates that it is NOT a measurement (not a weighing on a balance/bench scales) but rather it is a "STEP" in a procedure.

Thank you Neil!

Hello, the document is a translatron from Italian to English (I am doing the translation from English to Spanish) and I have found so many things that make no sense...
Regarding context:
This is the only time I have this phrase, here I copy the page where appears
-With these modifications, the analyses carried out on the samples produced during Blank Run 2, gave results within the acceptance range for both virus. The results are reported in table 9.3.
The analytical results demonstrated that the introduced changes were effective in assuring the correct reproducibility of the step on the chosen **bench scale**.
A third Blank Run was conducted with the only purpose of generating a new batch of Test ltem B for the completion of the preliminary experiments. For this reason, during Blank Run 3, only the sample at the end of the 3-hour incubation period was collected for the analytical tests and stirring interruption was not carried out.

Thank you
Neil Ashby May 16, 2022:
Hi Sebas From the less-than-perfect English in the source text, it could actually be talking about a weighing balance (scales). i.e., checking reproducibility of the weighing balance selected for the experiment.

It's almost certainly "a escala de lab.", like Liz says, but could you give us some more context that would confirm whether scale = weighing balance or 'size'/'dimension'?
TIA

en la balanza seleccionada

Estoy con lo planteado por Neil en la Discusión; para mi se trata de la balanza escogida.

Los resultados analíticos demostraron que los cambios presentados fueron efectivos en asegurar la correcta reproducibilidad del paso en la balanza seleccionada.

Un poco tarde (a lo mejor no tendrá "de acuerdo") pero creo que es el espíritu de la frase.

escala de banco / escala de banco de pruebas

Cuando se diseñan procesos o plantas para producción en la industria química/farmacéutica y otras, se va efectuando ese proceso o producción a distintas escalas.

Inicialmente es a nivel laboratorio (lab scale), luego a nivel banco de pruebas (bench scale), si bien esta puede ser coincidente (o no) con la lab scale, luego a nivel de planta piloto y luego en una planta de desmostración o directamente una planta normal de producción.

Una referencia:
https://en.wikipedia.org/wiki/Pilot_plant#Bench_scale_vs_pil...

Las traducciones usuales de "bench scale" son escala de banco o escala de banco de pruebas (Una referencia: https://www.linguee.com/english-spanish/search?source=auto&q... ). Según el caso, puede ser adecuado o no traducirlo como "escala de laboratorio", pero traducirlo así sin conocer si realmente se efectúa utilizando equipamiento de laboratorio y no de banco de pruebas es aventurado e innecesario. Como se puede ver en la presentación copiada debajo, entre las escalas de laboratorio y de banco hay diferencias de objetivos y de cantidades generadas del producto.
"Escala de banco" es jerga sumamente común en la industria. Por otro lado, no coincide con lo que escribió el autor (que no escribió "laboratory scale", otra frase muy usual).

Material de una presentación en slides que muestra la diferencia entre lab scale y bench scale a nivel técnico y de objetivos:

"• Laboratory scale (OK at university) – Done in test tubes etc., some grams of product
• Bench scale (OK at university) – Device fits in a normal room, kilograms
• Pilot scale (almost never at university) – A “small industrial machine” that requires several men to operate it, possibly has its own building, tens of kilograms to tons of product
• Industry scale, machinery may occupy the area of a university campus

4. These are the steps to industrial production!
• Lab scale: prove that a product can be made from raw materials (“Proof of concept study”)
• Bench: make enough product to test its properties, learn about fundamentals of processing, improve formulation
• Pilot: Try small scale production before bigger investment at high risk. Critical points? Problems? Automation? Space and power requirements? Help in designing a factory or plant! "

balanza de sobremesa

Hola, evidentemente nos falta contexto. Si el texto fuera más claro, estaríamos hablando de una balanza de sobremesa pero con el párrafo que citas no lo podemos saber. Suerte!
