Confirm your gas pressure and size of the gas line is correct. Confirm the auto-purge valve is opening correctly. If you have a flow control valve on your regulator, you may be getting a bit too much flow. Adjust this down slowly to reduce the over-pressure situation. Make sure you have enough flow and pressure to keep the valve open. You also need to confirm that your vent line is connected and operating correctly.

To set up your new glovebox you will need a basic set of fractional wrenches, a set of screwdrivers, and an adjustable wrench.

The foot pedal is for manually raising and lowering the pressure in the glovebox. It is typically used when placing hands in the glovebox or taking them out.

The ante-chamber door should only be tightened until it is snug. The best way to tighten the door is to use one finger to turn the handle. Tighten until you can’t turn it any more with that one finger.

This alarm means that the electro-pneumatic circulation valves on top of the filter column are not opening and closing properly. This is almost always caused by low gas pressure or an empty gas cylinder. Check the gas supply and make sure the system has at least 60 psi going to it.

On a full size glovebox the circulation blower is enclosed in a round stainless steel case and is located behind the filter column and in front of the vacuum pump. If you put your hand on the side of the blower housing it should be warm to the touch. This indicates that the blower is running. On a LCPW glovebox you should be able to hear the blower running. If you switch it on and off a few times you should notice a definite change in the sound.

This is also normal as the regeneration process causes water to be pulled from the filter material during the evacuation stage of the regeneration process. It is recommended to change the vacuum pump oil after each regeneration.

This is normal. The regeneration process produces steam and this causes water to collect in this line. It is external to the glovebox and does not cause the system any harm.

The internal solvent charcoal trap should be replaced every month. Your system was shipped with a set of 12 filters for one year of operation. The external solvent removal filter material (activated carbon) should be changed about every 3-6 months, depending on how much solvent you use.

The short answer is yes, but you should be very careful with solvent use inside the glovebox. You should use as little solvent as possible within the system. The glovebox system is completely sealed, so any solvent that evaporates is still within the glovebox and will condense or collect somewhere inside the gas purifier. It is highly recommended to use an internal solvent trap for trace amounts of solvent use or a large external solvent removal system for higher solvent use. It is also recommended to purge while using solvents, and for at least 10 minutes after using solvents. Some solvents—especially chlorinated solvents—can damage the filter material quickly.

Yes. All LC Technology gloveboxes are equipped with a quick release front window. It is easily removed/replaced in minutes. When replacing the window please make sure the gasket and window are free of any particles that might get into the seal area.

This is usually easy to notice. Typically if you have a leak in your system you will hear the gas solenoid clicking on/off constantly throughout the day. This is the system adjusting for the loss in gas pressure within the system. You will also notice an increase in the oxygen level in the system. If you think you have a leak please contact the service department at LC Technology.

Yes, the systems are all labeled for self-installation. Please refer to the operation manual for detailed instructions.

You need to run 3 evacuation and refill cycles to make sure that you do not bring any air into the system.

The analyzers are flow sensitive and the circulation blower is used to flow gas through the analyzers to get a sample of gas from the glovebox. Once you turn off circulation the flow stops and causes the analyzers to read a false high level of oxygen and moisture. Once you turn the circulation blower back on the levels will return to normal. Your glovebox is not leaking.

Our oxygen sensor is a very durable fuel cell design that is not damaged by most solvents.

For most applications we recommend a calibration interval of 5 years.

Once every 6 months. This is very important. If the filters get clogged they cause the blower to run hotter than normal and it can cause the blower to fail prematurely.

We recommend that you change your vacuum pump oil after every regeneration or every 3 months, whichever comes first.

No. The glovebox system does not require any cooling water to run.

You must purge the glovebox prior to running a regeneration. The regeneration process uses the glovebox environment for cooling and therefor needs to have a low oxygen environment inside the glovebox.

You will need to purge your glovebox when you first set it up. A standard single length system takes approximately 2 cylinders of inert gas to purge the system. As a rule, the amount of purge gas is easy to calculate. First you need to calculate the volume of your glovebox in cubic feet. A typical standard single length glovebox is approximately (4 ft X 2.5 ft X 3 ft) 30 cubic feet. An estimate is fine to use for this calculation. Then multiple the volume by 15 and you get a purge gas amount of 450 cubic ft. There is 300 cubic feet of gas in a standard gas cylinder so you will need 2 cylinders of gas. This is a very useful calculation for larger or smaller systems.

Yes. You will need a regulator for the regeneration gas. This regulator will need to deliver between 10-15 PSI of pressure and need to have a flow meter attached to deliver 15l/min of flow to the system while regenerating. This regulator will also need a 3/8” hose barb connection and should be equipped with a shut off valve. Please see your installation requirements for details.

You will need a regulator to run your system. The regulator will need to deliver between 60 – 80 PSI of gas pressure at a flow rate of 200 l/min. The regulator will need to have a 3/8” hose barb connection and should be equipped with a shut off valve. Please see your installation requirements for details.

You will need 1 standard cylinder of regeneration gas to start the system. One regeneration consumes half a tank of regeneration gas. You will most likely only regenerate your system once every 3-6 months and you can disconnect the regeneration gas when not in use.

You will need either nitrogen or argon at a purity of less than 10 ppm oxygen and moisture to operate the system. You will also need regeneration gas (3-5% hydrogen balance nitrogen or argon) for the regeneration process. A quality of 99.995% or better is required to operate the system correctly.

You will need to connect the common vent line to an exhaust connection in your lab. The common vent line connects all of the exhausts for the entire glovebox system into one connection at the top of the system. This is a 1.5” pipe connection labeled VENT at the top of the system, typically located behind the antechamber.

Your system comes with an electrical feedthrough to supply power inside the glovebox system. This is either 115V 10 amps or 220V 5 amps. A standard wall outlet will work fine for this as well. Please refer to Installation Requirements documentation for additional power requirements.

All standard glovebox systems are either 115V 15 amps for domestic installations or 220V 8 amps for international installations. A standard wall outlet should work fine for running the glovebox systems.

Used columns are of value. See instructions on how to repack the filter columns yourself. You will need to purchase the necessary filter material to repack the columns.  Please note this is a time consuming process.  We recommend purchasing our pre-packed, activated filter columns. The replacement columns cost $350 each and you will need two columns.

If you want to use a different solvent you will need new columns and an in-line filter. You will also need to remove the piping for that particular channel and thoroughly wash and dry them before using the new solvent. These steps are critical to avoid cross contamination.

Typically this is caused over time by solvents sitting in the filter columns unused for long periods of time. The solvent then reacts with the filter material and sometimes produces odd colors. Try dispensing 2-4 liters of solvent to flush the system. If this does not solve the problem, the filter columns will need to be replaced.

If you use solvent with a starting moisture content of 250 ppm or less the columns should dry approximately 800 liters. If the starting moisture content is higher, the amount is correspondingly decreased. Example: 500 ppm would equal 400 liters.

No. Once you have used one type of solvent in a solvent channel you cannot switch to another type of solvent. This would cause large amounts of cross contamination. If you want to change solvent types you would need to replace the filter columns (or the material), the particle filter, and clean out the entire channel of all of the old solvent. Then you could use a new type of solvent in this channel.

The color coding of the system is very important. You must always connect the correct color kegs to the matching colored lines to the same color solvent channel. (Example: Red keg, attached with red lines (gas and solvent), to red solvent channel). This color coding is important to keep the correct solvent in the correct kegs. Once you decide to put say, THF in the red keg, then it will always be in the red keg, red lines and red solvent channel. This is important to keep from cross contaminating your solvents.

Your full size system was delivered fully assembled. All you need to do is unwrap the system and the kegs. Remove all of the packing material and connect all of the color coded lines. Your bench top system needs some assembly. Please refer to the drawing of your system. Every piece of your system has a number label attached to it. If you match up the numbers each connection will be made correctly and the system will be assembled. This typically takes between 10 and 30 minutes maximum.

The system is supplied with one glass collection vessel for testing. Additional glassware can be supplied upon request.

The system is supplied with Teflon 24/40 connectors. Many other connection types are available upon request.

The full size system only comes one size (52” L x 34” W x 69” H). The bench top systems come in various sizes depending on the number of channels requested. Your system was supplied with a drawing showing the exact size and this information is also available on the literature supplied.

The vacuum pump exhaust should be vented out of the building through an exhaust connection. On full size systems you can also vent the fire cabinet and the top of the solvent purifier cabinet. This helps reduce the solvent vapors in the lab when using the system. The vent connections are shown in the operation manual. Refer to Section 3.4: Utility Connections.

The vacuum pump is not required to run the system 24/7 but is needed to operate the solvent purifier correctly. We recommend leaving the vacuum pump on all of the time.

The system is maintenance free and should not require any regular maintenance.

This is also very well explained in the manual. Refer to Section 5.2: Operation of the Solvent System.

This is very well explained in the manual. Refer to Section 5.1: Initial Start Up.

This is very easy to do and is well explained in the manual. Refer to Section 3.5: Filling the Solvent Kegs.

Yes. Each solvent channel has a particle filter. If you are using methanol your system will also have a special particle filter attached to that channel.

For the full size solvent purifier we recommend filling the kegs with 16 liters of solvent. For the bench top solvent purifier you will need 8 liters to fill the system.

There are several requirements for the solvents. It is recommended that you purchase ACS grade or better solvents with no more than 250 ppm of moisture content. If you are planning to use THF or ether it must be inhibitor free. The inhibitor (BHT) will react with the filter material and clog the system.

The gas connection for all of the solvent systems is on the back of the system. There is a gas inlet label on the back showing the connection point. This is also shown on your approval drawing.

The inert gas bottle will need to have a regulator that is capable of delivering 15 PSI of inert gas to the system. The system contains an internal regulator that is set to deliver 7 PSI within the system. A regulator at the gas supply (bottle) is required.

You will need inert gas (either nitrogen or argon) to run the solvent purifier. This should be high or ultra-high purity gas with less than 10 ppm of oxygen and moisture.

The system is already grounded to the vacuum pump which is then ground to earth ground through the power cord. No additional grounding is required.

The only item on the solvent purifier that requires power is the vacuum pump. For 115V systems the vacuum pump requires about 2 amps of power. For 220V systems the vacuum pump requires about 1 amp of power. A standard wall outlet is typically sufficient for this application.
