Hypoxic Fuel Cell O2 Sensor Control
A standard Fuel Cell O2 Sensor provides basic hypoxic control by displacement with nitrogen.
- IVF – Low oxygen levels aid in maturation, fertilization, and culture phases.
- Tumor Research – Replicate carcinogenic tumor conditions by reducing O2 levels.
- Aging studies – Research pathological conditions such as heart failure, diabetes, chronic obstructive pulmonary disease (COPD) in aging patients bsuppressing oxygen levels to replicate tissue degradation.
O2 Range: 2 to 21%
O2 Accuracy: ± 1.0%
Relative Humidity (RH) ControlA RH sensor continuously samples chamber humidity levels to monitor and control the humidity set point. If the system senses any variation in humidity, vapor is injected into the chamber by a water reservoir located underneath the chamber.
Dual Sterilization Cycles
Easily accessible through the NuTouch Intelligent Interface, In-VitroCell offers 145°C high heat sterilization and a 95°C humidified decontamination cycles as a preventative measures and to eradicate contamination in the growth chamber. On screen instructions read users through the process. A timer function is available to delay the sterilization process for an overnight procedure.
NuTouch Intelligent Interface
NuTouch is a user-friendly 5” x 7” (127 x 178 mm) color touch screen designed for high user adoption. The electronic control system is a microcomputer designed to service the precise control requirement of the chamber environment for culture growth. The microcomputer is supported with Read Only Memory (ROM) containing executable software, Random Access Memory (RAM) for temporary storage, and Electronically Erasable Programmable Read Only Memory (EEPROM) for control set points and parameters. The EEPROM provides for indefinite storage of these values during periods of power off or power interruption (power fault tolerant). NuTouch features are:
- Temperature and Gas Monitor and Control
- Status Indicators – Screen Identity; Run or Standby mode; Door Adjar; Air and CO2 Inject; Air and CO2 Chamber Sampling
- Date and Time Functions in International Format
- Password Protection
- Onscreen Icon Descriptions – Pressing on any icon will provide a description of what the item is.
- Onscreen Directions – Directions are available to perform calibrations.
- Step-by-Step directions (i.e. sterilization cycle procedure)
- Alarm Status Menu - A red “Alarm Status” text button will appear on the Main Screen to indicate a fault within the Incubator system.
- Maintenance Required Reminders – Onscreen Icon “MAINTENACE REQUIRED” appears when a programmable reminder (0 to 48 months) hits set point to notify filter check.
- Historical Performance Monitor – Temperature and CO2 gas history is available to view onscreen in graphical form or can be downloaded via USB for alarms, control systems, events, and performance information.

Constant Contamination Control (C3)A unique blend of product features to promote cell growth while minimizing potential contamination creating the most intrinsic and reliable growth chamber.
Closed Loop HEPA FiltrationA maintenance free air pump continuously draws environmental samples from two locations inside the chamber and passes the sample through a 99.99% HEPA filter before entering the sensor bay to measure gas and oxygen levels. The sensor bay measures gas and humidity levels from the sample to monitor before injecting back into the growth chamber. The NuTouch Electronic Control system will then determine the appropriate course of action to maintain chamber set-point conditions by placing the system on standby or injecting 99.99% HEPA filtered CO2 gas, air, nitrogen, or vapor into the growth environment.
ISO Class 5 Cleanroom Conditions
Based on clean room technology, In-VitroCell maintains the growth chamber at positive pressure similar to an ISO Class 5 Clean room to slow airflow to minimize desiccation. Anytime the chamber door is open to the laboratory environment, clean HEPA filtered will be forced out instead of contaminated lab air being drawn in.
Single Beam, Dual Wave Infrared (IR) SensorA microprocessor-based, non-dispersive, single source dual wave infrared (IR) sensor monitors and controls CO2 levels inside the growth chamber. Wavelengths are only absorbed by CO2 making measurement insensitive to other components, such as water vapor. The stable IR sensor has a controlled range of 0.1 to 20% accurate within 0.1%.
The chamber walls are surrounded by five (5) heating elements to control temperature. A door heater is separately controlled to minimize condensation on the inner chamber door. The heating elements are wrapped in a high density R5 insulation to maintain temperature integrity. Dual temperature sensor probes monitor and control temperature set points to ensure consistency and uniformity throughout the chamber.
A relative humidity level of up to 90% is achieved in the Incubator by the use of a stainless steel pan placed on the bottom of the chamber. An air pump injects fresh air into the chamber at a preset duty cycle to reduce condensation forming on the chamber walls and front glass door.
The inner chamber is constructed of high grade 16 gauge, type 304L polished stainless steel using crevice-free construction that provides an easily cleanable inert surface that does NOT promote biological growth. Seamless coved interior corners are easily cleaned promoting a healthy growth chamber. A single piece gasket creates a liquid tight seal from incubator chamber to inner door to eliminate condensation build up and potential contamination. Inner chamber shelving and gasket may be removed and routinely autoclaved if desired.
Minimal Vibration Promotes Cell Growth
By minimizes moving parts, In-VitroCell ES utilizes an accurate air pump to inject air and gas to eliminate potential vibration.
Smaller Footprint with More Useable Space
A large 7 cubic foot (200 Litre) growth chamber comes standard with four incubator shelves with a maximum capacity of 23 shelves. By attaching heating elements directly to the chamber and insulating with High Density R5 insulation In-VitroCell was engineered as a compact design while maximizing chamber capacity.
CuVerro® Antimicrobial Copper Surfaces (Optional Feature)
Add CuVerro® Antimicrobial Copper Surfaces to the incubator growth chamber and/or shelving to kill bacteria* to minimize potential incubator contamination. CuVerro® is laboratory tested and EPA registered. CuVerro® Antimicrobial Copper Surfaces kill more than 99.9% of bacteria* within 2 hours, and continues to kill 99% of bacteria* even after repeated contamination, when cleaned regularly.
EPA Reg No 85353-5
EPA Est No 088257-MN-001
*Laboratory testing shows that, when cleaned regularly, CuVerro® antimicrobial copper surfaces kill greater than 99.9% of the following bacteria within 2 hours of exposure: MRSA, Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas aeruginosa, and E. coli O157:H7. CuVerro® antimicrobial copper surfaces are a supplement to and not a substitute for standard infection control practices and have been shown to reduce microbial contamination, but do not necessarily prevent cross contamination; users must continue to follow all current infection control practices, including those practices related to cleaning and disinfection of environmental surfaces.
