The Benchmark Scientific H25050-70-E Dual-Convection Incubator for volumes of up to 40 liters provides the highest level of temperature control with uniformity and stability levels that are unmatched by competitive models in the same class. The H2505070E is equipped with the SureCheck data logging system for verification of chamber temperature. The SureCheck system records temperature data points as often as every 60 seconds and stores this information on a flash drive. The data can then be viewed and saved using the included the SureCheck software. The recorded data can also be used to plot temperature points on a graph or exported to a spread sheet program for verification or storage/record keeping. Unlike other laboratory incubators, the H25050-70-E offers "Dual-Convection" technology, allowing users to choose between mechanical convection mode* (for exceptional temperature uniformity) or gravity convection mode* (for longer incubations where airborne contamination or drying of samples may be an issue). The heating elements are strategically located on multiple sides of the chamber and contents can be viewed with the separate inner glass door without disrupting the temperature environment.

The SureTemp Incubators utilize a unique heating technology to ensure fast ramping times with high levels of uniformity and minimal temperature fluctuation.Independent heating elements create an evenly distributed, air jacket that surrounds the entire chamber. In gravity convection mode (fan disabled), this results in uniformity levels within 0.7 degrees Celsius and fluctuations of less than 0.8 degrees Celsius.When the fan is activated, the microprocessor automatically adjusts the heat distribution of each element. The elements now work in conjunction with the increased air flow, resulting in improved performance levels of 0.25 degrees Celsius (uniformity) and 0.1 degrees Celsius (fluctuation).

The stainless steel chamber ensures rapid and uniform thermal transfer, while the smooth-mirrored finish results in easy cleaning/decontamination. The included shelves (also constructed of stainless steel) are adjustable in height, providing the flexibility to hold a wide variety of vessels.The chamber conveniently includes an internal power outlet for connecting small instruments (shakers, mixers, etc.) inside of the incubator, providing temperature controlled agitation. The unique design of the outlet provides worldwide use, accepting USA, European and all common plug types.

The SureCheck data logger is included with each SureTemp Incubator. Simply insert a USB flash drive (memory stick) and use the up and down keys to choose the desired recording interval. The temperature will then be logged to a .txt file automatically. Intervals as small as one minute can be chosen, resulting in the temperature being recorded every 60 seconds.

Each incubator includes the SureCheck installation disc for easy viewing of the recorded data. The .txt files can be opened directly, or these files can easily be converted to a .csv file for opening/editing in Microsoft Excel.The data can be saved and recorded in list format, or can be converted to a temperature curve for a visual representation of the temperature readings. The SureCheck system is the easiest method for ensuring that samples have been properly stored at the desired temperature, when the user is not able to physically perform a periodic check.

* Mechanical Convection: Incorporates optimally positioned heating elements in conjunction with an internal chamber fan to control the internal temperature. Gravity Convection: Eliminates any airflow from the chamber, relying solely on the heating elements and gravity to control the internal temperature.
