English to Spanish Medical Medical: Instruments loosely capped slide jar

Buenos días,

Espero que puedan ayudarme con una expresión al español: “loosely capped slide jar”, relacionada con un kit de tinción. Muchas gracias:

“Staining procedure:

- In a loosely capped Slide Jar heat 10 ml of Reducing Solution in a microwave oven for 5 seconds at full power.
- Repeat as needed until solution is hot, but do not allow solution to boil. Remove Slide Jar from microwave, tighten cap and agitate to equalize temperature.”
