Introduction
The DST-1000 upgrade kit is applicable to DST-1000 units with serial numbers beginning with “V”. The kit
eliminates the top mounted filling funnel replacing it with a front fill tube that is easier to access. The fill tube
also has graduation marks that show the acid level in the still. A larger vent assembly also helps prevents
differential pressure build up and avoids surges when the fill tube cap is removed.
The instructions below will guide the user through the installation of the DST-1000 upgrade kit. The
installation will require removal of the existing unit’s safety funnel and stopper/dust cover, fill tube assembly,
top vent assembly, bottle bracket, and elbow drain. See red shaded items in Figure 1.
Safety Information
The following safety information should be read carefully prior to installing the upgrade kit for the DST-1000.
Installation of the DST-1000 upgrade kit may expose the user to residual acid that has previously been in the
DST-1000. Take appropriate measures and always wear recommended personal protective equipment during
the installation process.
Savillex assumes no liability for injury or damages resulting from improper handling or a failure to comply with
this information.

Assembly
Section 1 – Prepare Still
REMOVE ALL RESIDUAL ACID FROM STILL PRIOR TO DISASSEMBLY
It is highly recommended that all residual acid is removed from the DST-1000 prior to the installation of the
upgrade kit. This involves refluxing with deionized water following the steps below:
1. Drain any acid contents from the DST-1000 unit by opening the stopcock valve on the drain tubing and
directing the acid into an appropriate container
2. Close the stopcock valve
3. Drain any residual acid in the distillate collection channel inside of the still vessel by slightly tilting the
still in the direction of the distillate outlet and allowing liquid to flow into 1000 mL Purillex PFA collection
bottle
4. Disconnect distillate tubing, and remove the 1000 mL Purillex PFA collection bottle from bracket and
set aside. These items will be needed for the upgraded DST-1000.
5. Thread the enclosed ¼” OD ferrule plug on the distillate output port and tighten finger tight
6. Fill the DST-1000 with 500-1000 mL of deionized water
7. Turn the control knob on the power control unit to the HI setting
8. Allow the still to operate on the HI setting for the next 48 hours. The reflux action will transfer any
remaining acid inside the vessel into the deionized water in the reservoir.
9. Turn the control knob to the OFF position and allow the DST-1000 to cool.
10. Drain the DST-1000 as outlined in steps 1 & 2
11. The remaining distillate (approximately 50 mL) in the distillate collection channel inside the vessel will
also need to be drained. Carefully tilt the unit backwards so the distillate outlet is angled upwards and
the distillate has drained away from the opening.
12. Remove the ¼” OD ferrule plug from the distillate outlet and re-connect the 1000 mL Purillex PFA
collection bottle
13. Drain any residual chemical in the distillate collection channel inside of the still vessel by slightly tilting
the still in the direction of the distillate outlet and allowing chemical to flow into the 1000 mL Purillex
PFA collection bottle
14. Disconnect the DST-1000 from power outlet
15. Disconnect heater cable from heating control unit

Tools Required: Adjustable Wrench
1. Remove the safety funnel and stopper/dust cover. The safety funnel and stopper/dust cover are no
longer needed for the new DST-1000 and can be discarded
2. Remove the stopcock valve and drain tubing from the DST-1000. Set-aside the drain tubing and
stopcock valve fitting. These items will be used for the upgraded DST-1000.
3. Remove the fill tube assembly by unscrewing the ¼” MNPT x 3/8” ferrule connector fitting and fill tube
from top-middle of the still vessel (an adjustable wrench may be necessary to loosen and remove the
fitting). The fill tube assembly is no longer needed for the new DST-1000 and can be discarded.
4. Remove the vent assembly from the top of the vessel (an adjustable wrench may be necessary to
loosen and remove the vent assembly). The vent assembly is no longer needed for the new DST-1000
and can be discarded.
5. Disconnect distillate tubing, and remove the collection bottle from bracket and set aside. These items
will be needed for the upgraded DST-1000.
6. Remove the bottle bracket. The bottle bracket is no longer needed for the new DST-1000 and can be
discarded.
7. Lay the DST-1000 unit on its side to expose the underside of the still
8. Unscrew and remove the elbow drain fitting from the bottom of the still vessel. The elbow drain fitting
is no longer needed for the new DST-1000 and can be discarded.

Section 4 – Final Steps
1. Unscrew and remove the threaded cap from the graduated filling tube.
2. Carefully and slowly pour approximately 500 mL deionized water into the filling tube. DO NOT FILL
TOO QUICKLY: the water drains slowly into the reservoir. The fill tube has graduation marks which
indicate the liquid level in the reservoir.
3. While filling, check all fittings from the fill tube to the still for any leaks. If any leaks are present, check
all connections to ensure that the ferrule nuts are tight against the tubing and fitting. If leaks persist,
contact Savillex.
4. Drain the deionized water from the stopcock valve and drain tube in the front of the DST-1000. Check
for leaks as described in Step 1.
5. When all connections are confirmed leak-free, it is recommended to follow the initial cleaning
procedures in the DST-1000 user’s manual Section 4.4.
