What is the difference between the A, B, C, D, E variants in the SJIA series?
Each variant has a different manifold port count and cold trap configuration. Higher letter variants (D, E) typically provide more manifold connections for simultaneous multi-flask drying. Contact us to confirm which variant matches your vial format and quantity needs.
Can I use the SJIA series for shelf drying as well as manifold drying?
Yes. The SJIA series comes with circular shelf trays (Φ200 mm) for tray-based drying and optional manifold attachments for flask/vial drying. Both modes use the same condenser.
What vacuum pump is included?
The SJIA series ships with an SJ-matched rotary vane vacuum pump. Oil-free pump upgrades are available for clean-room or contamination-sensitive labs.
What is the minimum sample size the SJIA can handle?
You can dry as little as a single vial (0.5 mL). The manifold port accepts standard vials from Φ12 mm to Φ22 mm without adapters.
