Overview
The Decloaking Chamber NxGen has been designed for ease of use in heat-induced epitope retrieval (HIER). It has 5 discrete
temperature settings ranging between 60ºC and 110ºC with user programmable times. The 110ºC heat-induced epitope retrieval
protocol can be completed from start to finish in under an hour. With a capacity of 72 slides and only minutes of hands-on time per
run, the NxGen offers a walk-away capability similar to fully automated staining instruments.
The Decloaking Chamber NxGen transfers run data to a USB drive for export to a user’s computer. The run data recorded includes the
date and time per run with temperature and pressure readings throughout. With the Decloaking Chamber NxGen retaining the settings
from the last run, a quick start of the same protocol is possible.
The Decloaking Chamber NxGen is an excellent tool for HIER. The proper use of heat and pressure in conjunction with the appropriate
retrieval solutions is of the utmost importance for consistent immunohistochemistry (IHC) staining. The Decloaking Chamber NxGen is
designed to optimize and standardize antibody staining procedures and has been engineered to pass strict laboratory safety requirements.
Temperature, pressure and time can be monitored and recorded with the Decloaking Chamber NxGen to produce consistent staining.

2. Do not touch hot surfaces of Decloaking Chamber NxGen. Use handles only.
3. Never attempt to open lid while the unit is greater than or equal to 95ºC.
Do not open the Decloaking Chamber NxGen until the unit has cooled to below 95ºC and all internal pressure has been released.
If lid is difficult to rotate, this indicates that the chamber is still pressurized. Do not force it to open. Any pressure in the
chamber can be hazardous.
4. Do not use with glass or plastic containers.
The Decloaking Chamber NxGen has been designed using metal slide canisters for optimal heat transfer. Glass and plastic slide
holders are not recommended.
5. Always check that there is deionized or filtered water in the water chamber before use.
Do not run the unit when the metal water pot is empty, as this will cause the metal water pot to burn.
6. Always check that the pressure cable is connected before use.
If pressure cable is not connected, the Decloaking Chamber NxGen will not be able to record the pressure during the run.
7. Always check the pressure release device for clogging before use.
Do not operate without the pressure release properly installed.
8. Do not place the Decloaking Chamber NxGen in a heated oven or on any heated surface.
Do not place the Decloaking Chamber NxGen near a flame or gas source.
9. Keep the exterior of the unit dry.
To protect against electrical shock, do not immerse cord, plug or outer vessel in water or other liquids.
10. Adhere to the product voltage requirement and make sure it is compatible with the electrical voltage/frequency for the country
of operation.
11. Do not let the Power Cord hang over edge of table or counter, or touch hot surfaces.
12. Do not use outdoors.
13. Do not use under hanging cabinets, as steam from the pressure may cause damage.
14. Always attach Power Cord plug to appliance first, before plugging the other end into wall outlet. To disconnect, first unplug from outlet.
Note: Always unplug the power cord from the electrical outlet to fully disconnect power to the instrument.
15. For laboratories where multiple Decloaking Chamber NxGen units are in operation, it is important to note that each metal water
chamber is adjusted to its specific Decloaking Chamber NxGen. It is advisable to mark the metal water chamber to ensure it remains
with the correct Decloaking Chamber NxGen.

95°C Protocol Function
The Decloaking Chamber NxGen has the ability to preheat retrieval solutions when the 95°C protocol is selected. The preheat functionality
temporarily pauses the unit when the target temperature is reached, allowing the user to add deparafnized slides to retrieval buffers
that have already been warmed to 95°C. This workow modication enables better compatibility with protocols for breast tissue retrieval
that previously required the use of a water bath for preheating solutions.
The unit will beep when the target temperature has been achieved. The following message will be displayed (pictured below) on the unit
screen with two separate options for user input.
1. If slides will be added to the hot retrieval solutions, press the button under the “Load slides” option and open the unit to add the
necessary slides. Replace and secure lid. The run will resume automatically with the user selected hold time after the unit temperature
equilibrates back to 95°C.
2. If preheat is not needed and slides are already present, nothing needs to be done. After 2 minutes the program will automatically
proceed to the run screen and deduct the two minutes from the programmed hold time. If desired, press "Skip" to immediately move to
run screen. Any elapsed time will deduct from the programmed hold time.

11
Reporting Software
USB Flash Drive
The Decloaking Chamber NxGen has the ability to record run data, including run ID, protocol time, protocol temperature and pressure
to a USB drive. The run ID is an automatically assigned sequential number for each Decloaking Chamber NxGen.
The USB Drive must be present in order to record the run data. Do not remove the USB drive until the run is completed. The Decloaking
Chamber NxGen can be run without the USB drive present but the run data will not be retrievable after the run. If runs are completed
without the USB drive, the corresponding run ID number will be skipped when reviewing the data on the drive.
The USB Drive provided with the Decloaking Chamber NxGen contains reporting software that can be installed on users’ computers. The
Decloaking Chamber NxGen Reporting Software creates linear chart and summary table reports using the run data accumulated from one
or more Decloaking Chamber NxGen systems. Please refer to the “Software Installation” le on the USB drive for installation instructions.
Software Reports
Three different types of reports can be generated with the Decloaking Chamber NxGen Reporting Software. The report types include:
Chart Report
A chart report will provide a graphical output of the recorded temperature and pressure for any selected run captured by the
USB ash key. This type of report may be useful for documentation of the unit’s performance as well as association with any
calibration or verication procedures in use by the lab.
Summary Report by Instrument
The summary report by instrument provides a list of all runs initiated while the USB ash drive was in place on the selected
instrument. If run data was collected from multiple Decloaking Chamber NxGen, the Summary Report can be congured to list the
run data from a single instrument or for all associated units at once.
Summary Report by Date
The summary report by date generates a list of all of the runs performed between two user selected dates. If run data was collected from multiple
Decloaking Chamber NxGen systems, run completion summaries can be provided from a single instrument or all associated units at once.
Decloaking Chamber NxGen run les are stored on the computer’s hard drive after upload from the USB Flash Drive provided with each
instrument. Therefore, Decloaking Chamber NxGen run les collected from multiple USB keys (or multiple Decloaking Chamber NxGen
systems) can be reviewed from the same computer. Reports generated by the Decloaking Chamber NxGen Reporting Software may be
printed directly from the software or exported to a le for future reference.

NxGen. The best temperature for a Steam Monitor strip to show quality control is 110ºC +/- 5ºC. It is at this temperature and relative
pressure that a dark brown to black color is achieved. Lower temperature and pressure will produce a lighter strip. The steam strip can
be dated and recorded for laboratory and CAP inspections.
Cat. No. 613
QC Heat-Tested pH Strips
The pH of retrieval solutions at high temperatures can be critical for proper IHC staining. However, the pH of retrieval solutions can
change at high temperature. To assure quality control and consistent staining, Biocare Medical has developed heat-tested strips that
give accurate and true pH at high temperatures. The pH of a solution at a certain temperature can be recorded on a daily basis to comply
with JCOHA and CAP recommendations.
Cat. No. PH615 (pH 4-7); Cat. No. PH616 (pH 7.5-10.5)
