The series of XA 4Y.M.A.P PLUS microbalances is a modern solution for piston pipettes calibration where high accuracy and measurement speed are a must.

They are equipped with reliable measuring system housed in a hermetic casing, this guarantees fast and precise measurement in almost any laboratory conditions. External factors such as air drafts, dust, vibrations, operator competence - all of them generate disturbances that influence the final result of a measurement.

RADWAG-manufactured balances are equipped with range of protections designed to eliminate errors (hermetic weighing chamber, vibrations dampening filters), and tools informing about errors occurrence (vibration sensor, electronic levelling device, ambient conditions module).

4Y Series Balances

The 4Y Series displays are 5.7" resistive color touchscreens. They feature on screen keys plus 8 physical keys. The 4Y series has a customizable workspace and toolbar on the display. The series includes 19 databases. 2 programmable IR sensors allow for handsfree commands. Features an electronic level system. Interfaces include: (x2) UISB-A, (x2) RS-232, Ethernet, 4-IN, 4-OUT, Wireless connection. 

Antistatic Weighing Chamber

XA 4Y.M.A.P PLUS microbalance is a device 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 in-built ionizer.

The ionizer neutralizes electric charges inside the weighing chamber upon placing the sample in it. The lower relative humidity and a reading unit of the balance, the more evident influence of static electricity.

The ionizer neutralizes any uncompensated electric charge accumulated on the weighed object. The influence of static electricity gives greater repeatability error, often also greater error of indication. Measurement errors, due to the harmful effects of electrostatics, often reach the value of thousands of reading units and more. The problem concerns non-conductive samples, e.g. glass flasks, paper filters, plastics, etc. The antistatic ionizer implemented in the XA 4Y.M.A.P PLUS microbalance is a modern technology solution which 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 weighing instrument panel. The operation is signaled by blue diode which emits light when the ionizer is on.

The XA 4Y.M.A.P PLUS series is equipped with 5.7" LCD color touch screen facilitating device operation and presentation of the results. Complex databases enable users to register, print and export measurements. The weighing instrument system supports 13 languages.

Defined Profiles

'Defined profiles' is a new function, it automatically sets weighing instrument's parameters in accordance with user requirements.

Profiles:

• 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,
• USER - customization of the parameters in accordance with operator's requirements.

Innovative 2-Point Adjustment System

New adjustment system guarantees the highest measurement precision. Minimized linearity errors and 

The new system of the XA 4Y.M.A.P PLUS microbalance levelling guarantees:

• Ground tilt test
• Fully automatic balance levelling
• Balance level control
• Confirmation of balance levelling printed on adjustment reports and weighing reports.

With use of the "Smart Min Weight" function, the XA 4Y.M.A.P PLUS microbalance automatically adjusts resolution of the range to the currently weighed mass. This results with improvement of the minimum sample weight parameter by 30%.

All XA 4Y.M.A.P PLUS balances are compliant with 21 CFR part 11 and EU GMP part 4, annex 11. They are equipped with a number of security and monitoring functions that control work of particular operators and an electronic signature. Data protection is guaranteed by:

• Advanced password settings
• Verification of login operation correctness
• Assigning operators with individual permissions
• Auto logout
• Electronic signature, e.g. for series of measurements
• Granting/denying access to data management
• Database backup
• Modifications saved to Audit Trail file

Ergonomic Mechanical Design

Latch-type system of weighing chamber components fastening allows easy and tool-free assembly/disassembly which facilitates keeping the chamber clean, and which makes it easy to install a manual adapter for pipettes calibration.

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.

Door Opening Automation

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.

Pipettes Calibration Adapter

The pipettes calibration adapter enables calibration and/or verification of piston pipettes by means of gravimetric method. It is operated automatically using IR sensors. Evaporation ring is an integral part of the adapter that increases relative humidity inside the weighing chamber. With this evaporation of the liquid during weighing process is stopped.

Use of the pipette calibration adapter reduces maximum capacity of the balance by the mass of the weighing vessel.

Faster Measurement with the New CPU

The XA 4Y.M.A.P PLUS microbalances are equipped with Dual Core 2× 1 GHz processor and offer new possibilities of fast operation assuring short indication stabilization time at a respective repeatability.

16 GB Memory - New Possibilities of Data Management

Upgraded 16 GB memory enables record of measurement data in a form of reports, time and statistical graphs.

Remote Operation

Wi-Fi enables transfer of 4Y PLUS balances data to iOS or Android mobile devices 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.

• Update balance software
• Export weighing data
• Export/import databases
• Export/import balance settings
• Exchange data between balances

Optional functions:

• PRINT function
• TARE function
• Sensor's sensitivity adjustment

Elimination of extra sources of vibration

Using wireless terminal facilitates elimination of additional vibrations resulting from daily operation on a balance. Owing to that, balances with highest resolutions might be used without the need of dedicated weighing workstations.

Convenience and comfort of weighing in fume cupboards and laminar flow cabins

Wireless communication between a terminal and a weighing module makes balance operation more comfortable and safer.

Balance isolation form influence of environmental conditions

Wireless communication allows to either place the weighing module inside a draft shield or to isolate it from the operator. This allows to weight toxic substances without putting operator's health or life at risk.

• Ethernet
• 2×USB
• 2×RS 232
• 4 in / 4 out
• Wi-Fi 2,4GHz b,g,n

• Fully removable components of the weighing chamber
• Uncomplicated and fast disassembly requiring use of no tools
• Latch-type system for components assembly
