UYA 4Y PLUS STENT microbalance is a device from the family of professional weighing instruments intended for the most demanding applications. Innovative SYNERGY LAB line guarantees the best quality, precision and reliability.

The Best Repeatability and Compliance with USP
Smaller stents can be weighed with the readability of d = 0.1 μg. Measurement accuracy and repeatability of sd ≤ 0.08 mg, plus compliance with USP (Chapter 41 and 1251), make the 4Y PLUS series balance a new benchmark of mass measurement quality.
Solution for Stent Weighing
UYA 2.4Y PLUS STENT balance has been equipped with a special weighing pan for weighing of the smallest and the lightest stents, placed inside a special shield, and an applicator for stent loading.
Ergonomic Design
UYA 4Y PLUS STENT ultra-microbalance design ensures comfort of the everyday operation. The weighing chamber can be completely disassembled tool-free, which makes keeping the device clean easy. Thanks to a programmable IR sensors the chamber can be opened and closed touch-free.

Weighing Chamber Antistatic Characteristics
Special, antistatic coating compensates electrostatic charges accumulated on the substance sprayed over the stent, and laboratory accessories. With this the influence of electrostatics onto the weighing pan is limited.

Auto-levelling system of UYA 4Y PLUS STENT balance guarantees:
  • ground tilt test,
  • fully automatic balance levelling,
  • balance level control,
  • confirmation of balance levelling printed on adjustment and weighing reports.
2-Point Adjustment
The new 2-point adjustment system guarantees the most accurate measurement. Additionally it minimizes linearity errors which ensures reliable results within the whole weighing range.

Smart Min Weight
With use of „Smart Min Weight” function, the UYA 4Y PLUS STENT balance automatically adjusts range resolution to the currently weighed mass. This results with improvement of the minimum sample weight parameter by 30%.
Mobile Operation
Wi-Fi®®, which comes standard, offers the possibility to send data from 4Y PLUS STENT balance 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.

Data Safety
4Y PLUS STENT series balances feature internal ALIBI memory guaranteeing safety and automatic record of measurements, it also offers possibility to preview, copy and archive data.
Faster Measurement with the New CPU
UYA 4Y PLUS STENT balances are equipped with Dual Core 2× 1 GHz processor, they ensure short indication stabilization time at a respective repeatability, which results with fast balance operation.

16 GB Memory - New Possibilities of Data Management
Upgraded 16 GB memory enables record of measurement data in a form of reports, and time and statistical graphs.

Additional 21 CFR Part 11 Compliance Module
UYA 4Y PLUS STENT 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.
  • advanced password settings,
  • verification of log-in operation correctness,
  • customized user permissions,
  • auto log out,
  • electronic signature, e.g. for series of measurements,
  • granting/denying access to data management,
  • data backup,
  • modification record to Audit Trail file.
Defined Profiles
Four predefined profiles enable automatic customization of balance parameters:
  • FAST – measurement result obtained within 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.
Anti-Draft Shield
The standard equipment of the UYA 4Y PLUS STENT ultra-microbalance is an anti-draft chamber improving conditions in weighing rooms (air draft elimination). The ultra-microbalance is placed inside the anti-draft chamber, and sliding side panes enable easy access to the weighing chamber.
Filter Weighing Option
Innovative constructional solution enables the user to easily swap the weighing chamber with the chamber for filter weighing, which considerably expands the UYA 4Y PLUS STENT balance functionality. The characteristic feature of the chamber is high ingress protection. Large open-work weighing pan enables precise weighing of filters of various dimensions (max ø100). It is made of stainless steel resistant to chemicals, colour change and scratches. The additional chamber does not come standard with the UYA 4Y PLUS STENT ultra-microbalance.
