Quiz of the day, is your freeze dryer vacuum/drain valve fully closed ?

Before starting each freeze-drying batch, it's crucial to ensure that your vacuum and drain valves are fully closed. This step is essential for creating an airtight chamber, which is key to the efficiency of your freeze-drying process.

Routine Check: Alongside securely closing the acrylic door, make sure to press down on both the vacuum and drain valves with your finger to confirm their position. If either valve is not aligned at a 90-degree angle, it is not completely sealed.

Incorporate this check into your pre-batch routine to maintain optimal operation. This simple yet critical step ensures that your freeze dryer functions at its best, preserving the quality and integrity of your products. Remember, proper setup leads to perfect results!
