An adaptor configured for connection to a syringe having an air chamber and a liquid chamber, the adaptor including a liquid channel configured to be in communication with the liquid chamber, an air channel configured to be in communication with the air chamber and at least one filter positioned in the liquid channel.

Some embodiments are directed to a connector for connection with a fluid transfer device, including an outer body having a longitudinal axis; and a luer lock connection port positioned within the outer body and configured to be coupled with an external port of said fluid transfer device. The luer lock connection port can be rotatable about the longitudinal axis at least in one of a clockwise direction and a counter-clockwise direction at least prior to initiation of coupling thereof with the external port. The outer body can be structured, and the luer lock connection port is positioned therewithin, such that to prevent an operator to access, through the outer body, directly by fingertips an exterior of the luer lock connection port after the luer lock connection port has been coupled with the external port.
