The best possible repeatability and USP regulations conformity
The best weighing accuracy and repeatability – with sd ≤ 1d combined with USP regulations conformity (Section 41 and 1251) make 4Y PLUS balances a new standard for mass measurement quality.
Ergonomic Mechanical Design
The UYA 4Y PLUS ultra-microbalance features construction solutions ensuring convenient everyday operation. The weighing chamber can be disassembled without tools, which makes cleaning it convenient. Programmable infrared sensors, when respectively set, enable touchless opening and closing of the weighing chamber.
Antistatic Weighing Chamber
Specially designed antistatic panes coating compensates electrostatic charges accumulated on the sample and laboratory accessories. With this, the influence of electrostatics onto the weighing result is limited.
REFLEX LEVEL SYSTEM
New autolevelling system in UYA 4Y PLUS ultra-microbalances ensures:
- ground tilt test,
- automatic balance levelling,
- control of the correct balance level,
- confirmation of correct balance level on adjustment and weighing reports.
Innovative 2-Point Adjustment System
Brand new adjustment system guarantees the highest measurement accuracy. It minimizes linearity errors simultaneously providing reliable indications for the whole weighing range.
Smart Min Weight
With use of the “Smart Min Weight” function, the UYA 4Y PLUS ultra-microbalance automatically adjusts resolution of the range to the currently weighed mass. This results with improvement of the minimum sample weight parameter by 30%.
Remote control operation
Wi-Fi® module offers wireless transfer of data recorded by UYA 4Y PLUS balance to any portable device powered by iOS or Android systems using special applications intended for data management.
Every single UYA 4Y PLUS ultra-balance features ALIBI memory designed to provide protection and automatic recording of your measurements. Options such as data preview, copying and archiving are also
available to users.
Faster measurement with the new CPU
UYA 4Y PLUS ultra-microbalances feature Dual Core 2 x 1 GB processor which delivers noticeable performance improvements including faster operation and shorter stabilization time retaining high repeatability values.
16 GB RAM – more data management possibilities
16 GB RAM offers possibility of recording data in a form of complex reports. Time and statistic data diagrams on series of weighments are another useful option.
21 CFR Part 11 Compliance Module
UYA 4Y PLUS ultra-microbalances are compliant with 21 CFR part 11 and EU GMP part 4, annex 11. This means that the 4Y PLUS series features numerous functions for protecting and monitoring work results of particular operators. Full data protection is ensured by:
- advanced password settings,
- verification of log-in operation correctness,
- assigning permissions to operators,
- auto log out,
- electronic signature, e.g. for series of measurements,
- granting/denying access to data management
- data backup,
- modifications saved to Audit Trail file.
Four predefined profiles enable automatic balance parameters customization.
- FAST – the measurement result is obtained in a very short time,
- FAST DOSING – the balance quickly reacts to mass changes, especially useful for dosing or adding more product to the dispensed portion,
- PRECISION – balance settings providing the minimum standard deviation of sd ≤ 1,5 μg,
- USER – customization of the parameters in accordance with operator’s requirements.
Filter weighing option
This innovative solution enables the user to easily swap the weighing chamber with the chamber for filter weighing, which considerably expands the UYA 4Y PLUS ultra-microbalance functionality. The filter weighing chamber is characterized by high ingress protection. Large open-work weighing pan allows precise weighing of filters of various dimensions (max ø100). It is made of stainless steel which makes the chamber resistant to chemicals, colour change and scratches. The additional chamber does not come standard with the UYA 4Y PLUS ultra-microbalance.
