5. Nose shell

4. Installation of the Glass Rotary Flask

Set the Teflon seal ring on the assembled glass rotary shaft as shown in the drawing and then set the rotary flask nut on the bottom flask with the check ring on the flask neck. Rotary flask positioning: apply the allen wrench to insert into the hole (inclined left) of nose seat, turning the rotary shaft to make sure the shaft hole coincided with the seat hole, no inserting of allen wrench when the rotary shaft cannot be twisted any more. Last, install the rotary flask with retaining nut and check ring on the glass rotary shaft, tightening the rotary shaft nut. Turn the rotary shaft, ensuring the rotation steady and consistent with the shaft center.

5. Installation of Auxiliary Condenser and Three-Way Flask

　　a. Connection of R-1010 / R-1020 / R-1050 condenser with three-way flask

First, secure the pallet on the upright pipe and then place the auxiliary condenser (R-1010 / R-1020 / R-1050 provided with auxiliary condenser) on the mounted pallet, adjusting the height and ensuring the side connecting mouth of auxiliary condenser and three-way flask connecting mouth at the same level, fix the pallet and cross clamp screw .Then set the connecting flange on the bottom connecting mouth of auxiliary condenser with the check ring on the connecting mouth neck of auxiliary condenser. In the same way, set the other connecting flange and check ring on the three-way flask connecting mouth, place the flange seal washer in any of connecting bores of three-way flask or auxiliary condenser and finally tighten the retaining screw and nut. (As shown below)

Note: R1005 is not provided with auxiliary condenser, for which, the below method shall be directly adopted to connect the condenser and three-way flask.

1/3. 60# connecting flange

2. 60# flange seal washer

4. Three-way flask

5. 60# flange check ring

6. Auxiliary condenser

7. Cross clamp

8. Pallet

　　b. Connection of R-1010 / R-1020 / R-1050 auxiliary condenser with three-way flask:

First set the connecting flange on the bottom connecting mouth of three-way flask and set the check ring on the neck of three-way flask, insert half of the flange seal washer into the three-way flask bore and then set the connecting flange nut and check ring on one end of glass elbow, finally screw the nut and bolt together, adjust the condenser pallet to an appropriate height with the glass elbow in right direction, and in the same way, connect the auxiliary condenser and glass elbow with connecting flange and check ring which shall be tightened at last.

2/7. 60# flange seal washer

3. Glass elbow (deleted)

4/6/8/10. 60# connecting flange

5/9. 60# flange check ring

11. Three-way flask(deleted)

6. Installation of the Receiving Flask

　　a. R1005 receiving flask installation

Place the receiving flask on the pallet and lift it to a certain height; set the connecting flange on the bottom connecting mouth of receiving flask with the check ring on the neck, insert half of the flange seal washer into the receiving flask bore and then in the same way, set the connecting flange bolt and check ring on the lower connecting mouth of condenser connector; finally insert the lower interface of condenser connector into the other half of the flange seal washer and screw the nut and bolt together. Afterwards, in the same way, successively set the connecting flange and check ring on the lower connecting mouth of condenser and upper connecting mouth of condenser connector, with half of the seal washer inserted into the condenser connector bore. Then raise the height of receiving flask of the fixed condenser connector, ensuring the other half of the flange seal washer inserted in the condenser bore to secure the receiving flask pallet; tighten the connecting flange and make sure that the connecting mouths of condenser, condenser connector and receiving flask are closely meshing with each other without strain so as not to break the glass.
