The 21 CFR Part 11 Compliance Module is a solution especially useful for those users who are obliged (more) to conform to provisions of 21 CFR Part 11 and EU GMP Part 4, Annex 11 regulations. These two documents determine the rules for using electronic records and signatures. Data protection is guaranteed by: advanced password settings, control of logging correctness, various permission levels, data management access, backup, electronic signature, time-defined automatic logout, modification record to Audit Trail file. The module includes "Audit Trail". Audit Trail is a kind of a log where all modifications of balance settings, changes in database records and user activity are recorded. Audit Trail, for example, keeps record of previous and new modifications in databases and informs by whom and when they were introduced. This log allows the administrator to track and find out who logged in, when, who signed a document or who used invalid password. The Audit Trail Reader freeware allows users, upon connection with a balance, to display Audit Trail log and manage it by generating reports of various formats: pdf, xls, csv, html.

Balance of the AS R1 PLUS series is a standard analytical weighing device of the SYNERGY LAB line. T (more)he AS R1 PLUS is exceptional due to a range of modern constructional and system solutions that guarantee reliability, precision and accuracy of measurement, and make everyday operation easy. Ergonomic Mechanical Design The latest AS R1 PLUS analytical balance features spacious weighing chamber, and the open-door clearance facilitates easy access to the weighing pan. With this it is possible to use laboratory glassware of various sizes. New aluminium base is a guarantee for weighing system stability. Dual-CLICK system allows tool-free assembly and disassembly of the weighing chamber, and a special design of guides for weighing chamber panes (no rims) makes keeping the device clean convenient. Innovative construction solutions increase balance durability and reliability in long-term operation. Levelling System Standard AS R1 PLUS balances are equipped with a levelling device located at the front of the weighing chamber, which facilitates level control. Levelling operation is now simplified and easier due to the reduced quantity of adjustable supporting points (2 points). Intuitive Operation Balances are equipped with LCD display ensuring clear presentation of the weighing result. Direct access to functions and databases is possible via the following keys: Database – direct access to databases, Function – direct access to basic functions, F1-F4 – programmable function keys and menu navigation keys. AS R1 PLUS analytical balances signal operated working mode, computer connection, battery status, weighing and service functions via pictograms. The quantity of displayed weighing units is also expanded. Dedicated status bar enables display of additional messages, e.g. product name, tare value. Real-time mass measurement is presented using bar graph. ALIBI Memory Data safety is ensured by the ALIBI memory integrated into AS R1 PLUS balances, which enables record of up to 100 000 weighings. ALIBI guarantees continuity of data collection over a long period of time. Data Protection Access to valuable information is possible after logging. The administrator manages the data access configuration. Databases The information system is based on 5 databases, which allows several users to work with several product databases, and the registered weighing results can be subject to further analysis. The data is registered in 5 databases: operators (up to 10 users), products (up to 1000 products), weighings (up to 5000 weighings), tares (up to 100 tares), ALIBI memory (up to 100 000 weighings). Communication Interfaces The functionality of AS R1 PLUS balances can be expanded using the following communication interfaces: USB-A, USB-B, RS 232, Ethernet, Wi-Fi (option). The additional USB port located at the front of the balance enables easy and fast communication with the USB flash drive, it is possible to connect additional devices via this port too. AS PLUS balances are equipped with Kensington Lock, which allows to secure the device against theft.

XA100 pipette calibration adapter enables calibration and/or verification of piston pipettes by mean (more)s of a gravimetric method using the XA analytical balence. Set content: base weighing pan weighing vessel evaporation ring glass chamber with an opening for dosing Evaporation ring is an integral part of the adapter that increases relative humidity inside the weighing chamber. With this evaporation of the liquid during calibration/verification is stopped. An integrated weighing pan enables centric loading of the vessel in the weighing chamber. The weighing pan and the vessel are housed in a glass chamber featuring an opening allowing the user to dispense liquid through it, and reducing air drafts. Vessel capacity: 100 ml Adapters for Pipettes Calibration Pipette calibration adapters are intended for calibration and verification of piston pipettes using gravimetric method. Use of the pipette calibration adapter reduces maximum capacity of the balance by the mass of the weighing vessel. The table below, which presents the minimum requirements in accordance with ISO 8655-6:2022 standard, enables to select suitable adapter for pipette calibration and respective balance version. The parameters of the balance have been selected so that the expanded uncertainty of measurement in use is less than ¼ of the maximum permissible error of the test object.

THB sensor THB sensor is a device measuring ambient conditions, it cooperates with: a computer (1 se (more)nsor via USB 2.0 port); direct cooperation, a weighing device (1 sensor via USB 2.0 port); direct cooperation, a THBR Box (up to 4 sensors connected to THBR Box via USB 2.0 port). The THB sensor is designed to measure parameters such as temperature, humidity, pressure, air density and vibrations level. Sensor registers level of permissible vibrations at the workstation, wherein the values of vibrations level are displayed within 0 - 100% range versus reference values in laboratory conditions. Values exceeding 100% threshold inform about potential occurrence of error greater than permissible error of mass measurement performed using weighing device. Each sensor has its own identification number that is assigned to measurements saved to the database. Ambient conditions can be monitored using: weighing instrument display website Windows OS application: THB Single or THB Multi Android application. On the basis of sent measurements, the THB Single or THB Multi software determines air temperature, humidity, pressure, density and permissible vibrations factor.

THBR BOX is an autonomous measuring device operating in a local computer network. THBR Box enables c (more)ollecting ambient conditions measurements, storing the database, sending customized warnings and alerts and generating website for accessing measurements and settings. THBR Box There are three models of the recorder: with an integral screen, with a separate screen, without a screen. Communication with THBR BOX can be established wireless or via Ethernet. The module enables direct connection with up to 4 sensors. With use of USB hub it is possible to connect greater number of sensors. Each sensor has its own identification number that is assigned to measurements saved to the database. THBR Box features the following connectors: 4xUSB, HDMI, Ethernet. The device is powered using external micro USB 5V 2A power supply. Data stored by the THBR Box can be presented via THBR Multi software, website or Android application.
