Smaller stents can be weighed even with the readability of d = 1 μg. The highest measurement accuracy, repeatability of sd ≤ 0.01 mg and compliance with USP (Chapter 41 and 1251) make the 4Y PLUS series a new benchmark of mass measurement quality.
The XA 4Y.M.A PLUS STENT balances are equipped with specially designed weighing pans for weighing even the smallest and lightest stents. They feature an additional shield and an applicator for stent loading.
New adjustment system guarantees the highest measurement precision. It also minimises linearity errors to ensure reliable results over the full weighing range.
Reflex Level System
The new autolevelling system of the XA 4Y.M.A PLUS STENT balance guarantees:
- ground tilt test,
- fully automatic balance levelling,
- balance level control,
- confirmation of balance levelling printed on adjustment reports and weighing reports.
The innovative weighing chamber system for door opening and closing guarantees smooth and quiet door movement, and eliminates vibrations that may disturb the measurement. The solution enables to define how wide the door is to be opened.
Fully Antistatic Weighing Chamber
The XA 4Y.M.A PLUS STENT balances are devices where the influence of electrostatics onto the weighing result has been eliminated due to use of special antistatic coating of the glass panes, and thanks to an integrated ionizer. The antistatic ionizer generates positive and negative ions alternately, leading to an electrostatically inert working environment. The substance with which the stent is covered, when placed in such an environment, also becomes electrostatically inert, so that the weighing process runs smoothly. The antistatic ionizer implemented in the XA 4Y.M.A PLUS STENT balances compensates both cations and anions. The ionizer activates when the balance door opens, and deactivates when the door is closed. It is possible to control ionizer operation using the weighing instrument panel. The operation is signalled by blue diode which emits light when the ionizer is on.
With use of the "Smart Min Weight" function, the XA 4Y.M.A PLUS STENT balances automatically adjust resolution of the range to the currently weighed mass. This results with improvement of the minimum weight parameter by 30%.
When the sensors for constant monitoring of ambient conditions and level status record deviations, the balance displays warnings about potential errors occurrence during weighing.
Additional 21 CFR Part 11 Compliance Module
The XA 4Y.M.A PLUS STENT series balances are compliant with 21 CFR part 11 and EU GMP part 4, annex 11. They can optionally feature an electronic signature function and be equipped with a number of security and monitoring functions that control the work of particular operators.
Data protection is guaranteed by:
- advanced password settings,
- verification of log-in operation correctness,
- assigning permissions to operators,
- auto log-out,
- electronic signature, e.g. for a series of measurements,
- granting/denying access to data management,
- data backup,
- modification record to Audit Trail file.
16 GB Memory - New Possibilities of Data Management
Upgraded 16 GB memory enables record of measurement data in a form of advanced reports, time and statistical graphs.
Ergonomic Mechanical Design
Latch-type system of weighing chamber elements assembly enables their quick, uncomplicated and tool-free assembly/disassembly. This makes it easy to keep the chamber clean and allows the manual pipette calibration adapter to be assembled. Smart system of pressures equalization guarantees stable measurement. It eliminates errors generated by rapid change of pressure inside the weighing chamber. A real novelty is an option of lighting the weighing pan up using a LED diode. The diode does not affect the weighing chamber temperature.
Standard Wireless Connection offers possibility to send data from the 4Y PLUS balances to a mobile iOS or Android device via special data management apps. Wireless communication between the indicator and the weighing instrument enables operating the 4Y balance that is placed inside laminar flow hoods and fume cupboards.
All LAB SYNERGY line balances feature internal ALIBI memory guaranteeing safety and automatic record of measurements, they also offer the possibility to preview, copy and archive data.
Four predefined profiles enable automatic customization of balance parameters:
- FAST – the measurement result is obtained in a very short time,
- FAST DOSING – quick reaction to mass changes, useful for dosing or adding more product to the dispensed portion,
- PRECISION – balance settings providing the minimum standard deviation,
- USER - customization of the parameters in accordance with operator's requirements.
Under-pan weighing will only be possible on balances that are equipped with this function in the production process. The need for such (extra-paid) functionality should be reported at the time of placing the order.
