Low profile transfer mechanism for controlled environment

A system for transferring objects into a device inside a controlled environment, comprising:

• a winch comprising a drum and wire arrangement configured to be reversibly wound onto the drum by a first drive;
• and
• a tool suspended below a distal end of the wire arrangement and configured to suspend an object therefrom, wherein both the tool and the object are sized to fit inside a device located below the winch;
• and
• a carousel connected to a second drive configured to rotate the carousel around a vertical axis, the carousel comprising a storage space centered at a first horizontal angle and a pass-through opening at a different second horizontal angle, wherein the carousel is configured to selectively position the storage space and the pass-through opening under the tool by rotating around the vertical axis, wherein the pass-through opening is large enough to pass the tool and the object suspended from the wire arrangement therethrough as the wire arrangement is unwound from the drum and the tool and the object are thereby lowered relative to the carousel into the device.
