The A&D Weighing BA225DTE Dual-Range Semi-Microbalance provides exceptional efficiency and saved time - improving daily tasks and routines while meeting various laboratory requirements - as well as fully reliable results. With a 5-inch wide color touch screen, the BA-225DTE brings maximum operability, enhanced functionality and a broader range of solutions. The unit come standard with an external ionizer (static eliminator).
Automatic opening/closing of the breeze break doors
The side doors of the breeze break can be opened/closed using the non-contact IR sensors on the display unit for smooth, efficient access to the weighing chamber. For the actuator, BA-225DTE features a pump and air cylinder mechanism, which is much quieter and more durable than conventional motor actuators.
Touch screen and user navigation
The BA-225DTE has a touch screen, enabling intuitive operations while making it easy to enter numbers, change settings, etc. Users can operate it even if they are wearing thick gloves, as the unit responds to pressure (i.e. resistive touch screen).
Easily separable glass panes
Each glass pane of the breeze break can be easily separated for thorough cleaning/disinfection, thanks to the BA-225DTE's unique clip system.
Detachable breeze break unit
The breeze break unit itself can also be easily detached from the weighing unit by pulling out the two side fasteners. This allows for fast, simple cleaning as well as easy replacement, in case of failure.
On-screen leveling assist
The BA-225DTE touch screen provides a visual instruction on which leveling foot (feet) to rotate in which direction(s), depending on the position of the air bubble on the level indicator (available as part of the daily check function).
AD-Just – Automatic self sensitivity adjustment
The BA-225DTE balance can be set to calibrate and adjust its sensitivity automatically using its internal weight, according to the set execution condition (i.e. temperature change, preset time or interval) when there is nothing on its weighing pan. An indicator (message for unit) blinks to give notice before the adjustment starts.
Internal repeatability test
It is also possible to have the BA-225DTE test and calculate repeatability (standard deviation) using its internal weight to quickly assess the performance under a given environment. The repeatability measurement mode can be immediately accessed by pressing [P-TEST] on the screen, which enables repeatability testing using an external weight as well as the internal weight.
Impact shock detection (ISD)
The ISD function detects impact loads applied to the weighing sensor and indicates their strength in five levels from 0 to 4. Level 3 and Level 4 are also accompanied by a beep sound. Using this as reference, the user will be able to reduce impact loads in future weighing, and thereby avoid measurement errors as well as potential damage to the weighing sensor. Impact loads of Level 3 and Level 4 are saved in the Impact Shock Detection History log. When there is a problem with the balance, the log can be used to check how the balance was used.
Smart routine check (SRC)
The SRC function displays the balance handling level, or how adequately it has been used, in three levels based on the number and strength of impact loads received by the weighing sensor (available as part of the daily check function). This allows the user to assess and manage risk related to poor handling, and helps improve balance operating skills.
External ionizer for instant static removal
With the provided ionizer, the user can easily ensure that their sample (and container) are completely free from destabilizing static electricity. Since a DC method is adopted, no fan is needed to deliver ions, and therefore no breeze is caused (except for minimal ionic wind), enabling static removal without disturbing even extremely fine powders.
The ionizer draws power via the BA-225DTE balance. For seamless weighing workflows, it can be installed next to the balance and activated for a set duration by hovering a hand over the embedded IR sensor, right before a sample is placed inside of the breeze break.
Daily/periodic balance check support
The BA-225DTE aids in the application of standard operating procedures (SOP) for quality and performance verifications without trouble. The daily check is conducted to confirm that the balance is in good condition, whereas the periodic check is conducted to regularly inspect basic performance. No comprehensive knowledge or experience is required to implement these checks. Simply follow the displayed procedures step-by-step (or skip the items that are not needed for the laboratory). It is possible to set the balance to remind the user of these checks. Meanwhile, the results can be printed out or saved to a USB flash drive in a PDF report format for documentation and compliance.
Minimum weight setting and alert
The user can set the minimum weight for the BA-225DTE balance either by direct key input, or by performing a repeatability test, from which the balance automatically calculates the minimum weight. To ensure that the measured sample amount meets the minimum weight requirement, the balance can keep displaying an alert message until the sample amount reaches the value set as the minimum weight. It is also possible to set the balance to disable output of weighing data smaller than the minimum weight.
Advanced user access control
To prevent unauthorized changes from being made to balance settings/data, users can be classified into four levels (i.e. administrator, lab manager, supervisor, and operator), and the administrator can determine the extent of rights (i.e. change to settings, date/time setting, external sensitivity adjustment, and internal sensitivity adjustment) for each level. The administrator can register users as either lab managers or supervisors with usernames and passwords. Up to 100 users can be registered, including the administrator.
History information
The balance can display/save to a USB flash drive log-in/log-out history, operation (changes to settings) history, sensitivity adjustment history, and impact shock detection (ISD) history with date, time, username and other necessary information for later reference.
GLP/GMP/GCP/ISO compliant output
Data necessary to comply with GLP/GMP/GCP/ISO can be added to sensitivity adjustment reports, calibration test reports, and a series of weighing results.
Formulation mode
The BA-225DTE features a formulation mode, enabling quick, accurate weighing of multiple samples to mix according to a set recipe, while allowing for setting the target value (g) and tolerance (%) for each sample. Up to 150 samples and 300 recipes can be registered in the balance for easy creation or selection/change of recipes.
HPLC mode
The HPLC mode is dedicated to preparing buffer solutions for high-performance liquid chromatography (HPLC). In addition to weight (g), it enables the user to set the target quantity of each sample in terms of molar concentration (mol/L or mmol/L). From the molecular weight of the sample and the volume of the buffer solution to be made, the BA-225DTE balance automatically performs conversion between molar concentration and weight, which is a common source of error when manually calculated.
