Freeze Drying Apparatus, Umbrella Design, Ace Glass
The economical "umbrella" design of this freeze drying apparatus utilizes Ace-Threds for positive, grease-free connections that are easy to manipulate
Cooling is done in Dewar in the usual manner. If the main tube of the umbrella or cooling trap should clog, it may be disassembled, cleaned and reassembled in minutes without fear of vessel "drop-off". Capacity of the trap is approximately two liters.
Compression fitting of nylon bushing on FETFE o-ring against the shoulder of the Ace-Thred holds the vessel in place with or without vacuum, and thus prevents vessel "drop-off" at start-up or shut-down. The "umbrella" has three #25 threads at 90° angles of each other, leaving the rear of the umbrella without a port for easier mounting. A vacuum gauge connection is located near the top of the umbrella. A vertical tube extends down from the umbrella, and it is secured in the collection trap by a #50 Ace-Thred.
