2 System Overview
PureLab HE is designed as a complete package including box, Antechamber(s), gas purification
system and vacuum pump. The system is capable of removing O2 and H2O to levels less than 1
ppm. O2 and H2O are removed from the inert atmosphere by a combination of molecular sieve
and copper catalyst. Once saturated, these materials are easily regenerated to their original state.
The PureLab HE has been designed with the user in mind.
The Operator Interface comprises a color HMI (Human Machine Interface) touch screen that
is mounted on a swing arm for ease of use.
The foot pedal allows the operator hands free control of the box pressure.
Interior and exterior doors are easy to operate.
The controls and indicators are simple yet fully functional.
The PureLab HE (Figure 1) is designed to be a completely modular system. The gas purification
system is contained within a separate module that is located beneath the large Antechamber.
This module has casters allowing easy movement for servicing.
All service connections are located on the rear of the gas purification system and are clearly
labeled.

3 Installation
This section explains how to install a PureLab HE Glovebox
3.1 Pre-Installation Requirements
3.1.1 Working Gas
The working gas requirement is Nitrogen, Argon or Helium with a suitable regulator to adjust
pressure to 55-60 psi. The working gas must be connected to the gas inlet on the Glovebox
either by flexible hose or hard copper plumbing to a 3/8" compression connector. Four (4)
cylinders are required: three (3) for purging and one (1) for the final operation of the Glovebox.
Note 1: Refer to system specific installation requirements for further details. This document was
supplied prior to shipping the system. Please contact your local Innovative Technology
representative if you need another copy.
Note 2: The working gas tubing must be 3/8” outside diameter for the entire distance from the
regulator to the working gas connection. Any reductions in tubing diameter will result in
insufficient gas flow for optimum system performance. Outside North America the connections
and tubing should be 10mm
3.1.2 Regeneration Gas
Note: The gas purification system has been regenerated and performance tested to < 1ppm of
O2 ands H2O at our factory prior to shipment. It does NOT need to be regenerated prior to first
use upon installation.
One cylinder of Nitrogen or Argon containing approximately 3 to 7% Hydrogen.
3.1.3 Electrical
All Innovative Technology, Inc. Glovebox systems are configured to operate using the electrical
power standard for the region in which the Glovebox has been ordered.
Note: The standard 2-glove system requires 2 electrical outlets, one for the main system power
and one for the power supplied to the power strip inside the Glovebox. Larger systems and those
configured with other options require additional outlets.
3.1.4 System Exhaust
Note: The Regeneration Gas, Vacuum Pump, and Purge exhausts should be handled in
accordance with your facility’s required specifications.
The regeneration gas exhaust is 3/8" I.D., 19/32" O.D. Tygon tubing. The Vacuum Pump
exhausts are 1" OD tubing. The purge valve should also be vented, 1" Female NPT (manual
purge) or KF-40mm flange (automatic purge).
WARNING: Proper ventilation of the exhausted gases is imperative as high levels of inert gas
can cause asphyxiation.

Installation
14 of 80 Pure_Lab_Manual Rev 6_4-14-2015.docx
3.2 Unpacking the System
All systems shipped outside North America are packaged in specially designed shipping crates.
These systems require a forklift or similar lifting device to safely remove the Glovebox and Gas
Purification module from the crate. For more information, please ask your Innovative
Technology, Inc. representative.
WARNING: Glovebox systems are typically top-heavy.
All systems shipped within North America are shipped on a special-designed pallet that includes
detachable ramps to enable the Glovebox and Gas Purification module to be rolled off the pallet.
Please ensure that you have sufficient personnel available to assist in the unloading process to
ensure personnel safety.
To unpack the Glovebox system
1 Place the Glovebox and gas purification module on a level floor in the desired location.
2 Remove the shrink-wrap and any other strapping that may be supporting the vacuum pump
or any other accessories.
3 Depending on the exact system configuration purchased, there will be one or more boxes
containing items such as gloves, power strips, etc. inside the large Antechamber and on the
pallet. Carefully inspect all packaging materials before discarding to ensure that any small
components are not misplaced.
3.3 Assembly
Figure 2 Assembled Glovebox

Installation
Pure_Lab_Manual Rev 6_4-14-2015.docx 15 of 80
Note: For double box systems, the two boxes need to be joined prior to performing the
following procedure. See the next procedure, “To assemble a double box system”.
To install the Glovebox system
1 See Glovebox layout drawing (Figure 1).
The Glovebox system has lockable casters on each leg to facilitate its placement. Once in
place, the casters can be adjusted to lock the system in place.
2 Level the system by adjusting the leveling feet underneath each leg.
3 Place the Gas Purification module underneath the Large Antechamber.
4 Connect the Gas Purification module to the Glovebox. Match up the labels on the piping and
components to the labels on the Glovebox and the gas purification module. e.g., “1” connects
to “1”, “2” connects to “2”, “A” connects to “A”, etc.
5 Lock the Purifier Cart into place by adjusting the casters.
6 Locate and install the shelves inside the box at your preferred height. The shelves are
adjustable and can be relocated at any time. Fit the shelves into the box by sliding them
through the Antechamber. It is not necessary to remove the window.
7 Place the power strip in the box as desired. Connect the male plug to the female outlet, which
leads to the feed-through on the side of the box.
8 The oxygen analyzer requires that the small sampling pump be connected to the black tubing
connected to the bulkhead fitting on the inside of the Antechamber wall. The batching pump
should also be plugged into the electrical power strip inside the Glovebox.
9 Attach the purge valve to the corresponding KF-40 flange located on the top of the
Glovebox. The purge valve and flange are labeled like the removed plumbing. For the auto-
purge version, locate and connect the electrical and pneumatic lines.
10 Install the gloves. Gloves are placed inside the box through each glove port. The cuff end of
the glove is stretched over the glove port until the lip fits into the last groove. Two O-rings
are then stretched over each glove and placed in the outer two grooves.
To assemble a double box system
1 Remove the window from one box. See “Removal and Replacement Procedures” on page
69.
2 Press both boxes together and make them level on the inside by adjusting the leveling feet.
After the boxes are level, lock the leveling feet into position.
3 Press both boxes apart far enough so that you can fit between them. Apply a bead of DAP
latex sealant, approximately 1/8"-3/16" wide continuously around the flange of one box in
the area between the inside of the box and the bolt holes.
4 Press the boxes together and put in the four corner bolts. After the four are in and hand tight,
insert the rest of the hardware and tighten all bolts. Excess sealant will squeeze out from
between the flanges.
5 Clean the excess sealant; it is easier to do this when the sealant is slightly dry. Clean the
entire interior of the Glovebox.

with this switch. There is no other action necessary to turn power on with the possible exception
of optional equipment.
The fluorescent light in the hood is controlled by its own manual switch located on the top of
the light hood.
3.7.2 Pressure Testing the System
The Glovebox system is a leak-tight, hermetically sealed system. The entire system has been
pressure and performance-tested prior to shipment. After assembly, the system must be pressure
tested to ensure that all of the fittings and pipework have been connected properly.
After initial power on, the Glovebox Control screen shows the following display (Figure 3). In
order to change any setting, the user must log in to the system.

6 Use the appropriate foot pedal to add/remove gas to/from the Glovebox to reach a pressure
of 11.0 mbar.
7 Using a timer, wait 25 minutes and observe the current box pressure.
If the pressure has not decreased more than 1 mbar in this time period, the Glovebox is
leak tight.
If the pressure drops more than 1 mbar, check all of the connections that were made
during the assembly process. Contact your Innovative Technology, Inc. representative if
you require assistance in troubleshooting.
3.7.4 Purging
The purpose of purging the system is to displace the air in the box with the inert gas of your
choice. It is extremely important to displace as much of the air as possible prior to circulating
the inlet gas through the purifier column. It is advisable to use at least three cylinders of gas per
Glovebox module during this purging procedure and to reduce the O2 and H2O levels to less
than 50 ppm.
Note: If you have a freezer, the door should be open during purging.
The purging method is as follows:
1 Set the Working Maximum pressure to +10.0 mbar and the Working Minimum Pressure to
+5.0 mbar See “Adjusting the Box Pressures” on page 18.
2 Open the manual purge valve located on the top left of the box. If your Glovebox system is
fitted with an Auto Purge valve, refer to “Purge Control” on page 30.
3 Adjust the flow using the purge valve so that there is a steady flow of incoming gas and the
box pressure is maintained at >1mbar.
4 Create turbulence in the box to increase the efficiency of the purge. This can be done by
pressing in the gloves and waving inside the box or installing a small electric fan inside the
box.
5 During the purge process you will need to change the working gas cylinder as it empties.
You must close the purge valve before changing the cylinder.
6 Re-open the Purge valve after replacing the cylinder and opening the valve on the cylinder.
7 Purge the system with at least 3 cylinders of inert gas for a standard 2-glove system.
Note: If you do not have an Oxygen Analyzer, it can be assumed that after purging with
three (3) cylinders (for a single 2-glove system), the Oxygen content in the box is 25 ppm or
less. Close the Manual Purge valve..
8 The O2 level may increase after the blower has been turned on. If the O2 level exceeds
100 ppm, stop the blower and continue to purge. Repeat steps 6 and 7 as necessary.
