No space in your fume cupboard or access to the weighing terminal? Or maybe you want to operate the balance remotely?
Thanks to the hotspot, you can operate the balance on any device previously connected to it. This can be a smartphone, tablet, or computer
ELLIPSIS will connect you directly to:
smartphone or a tablet (hotspot)
spreadsheet (USB-C, Free Link)
printer (Ethernet, Wi-Fi®, USB-A)
computer (Ethernet, Wi-Fi®, USB-A)
barcode scanner (USB-A)
any large screen (HDMI)
your PC software (Radwag communication protocol)
keyboard and mouse
Ambient Light – one look and everything’s clear
Innovative way of user – balance communication.
It couldn’t be easier: the backlight colour informs you about status, process results, procedures, or alerts.
Looking for more than just weighing?
Weighing - Basic working mode that displays the mass of a sample
Parts counting - Quick counting of samples of similar mass
Checkweighing - Control of sample mass in the set min/ max thresholds
Dosing - Weighing to a target value
Percent weighing - Percent mass control
Density - Determining the density of solids and liquids
Animal weighing - Control of mass change over a set period of time
Formulations - Weighing of predefined ingredients, according to the order described in the formulation
Statistics - Real-time statistics determined from carried out weighings
Pipette calibration - Checking piston pipettes according to customer-specific requirements or ISO 8655
Differential weighing - Analysing the change in mass of a single sample over time
SQC - Statistical mass control with set thresholds
Peak hold - Control of the maximum mass on the pan
Mass control - Statistical control of samples of similar mass
Comparator - Control of mass standards
PGC - Statistical mass measurement in accordance with Packaged Goods Control
Always the correct choice of a product or ingredient for a formulation.
ELLIPSIS works with RFID tags* that can be used to tag your products or formulation ingredients in the database. It can also be used to identify a user
* RFID ISO/IEC 14443 Type A, 13.56 MHz
Always at hand, grouped so that the essentials never slip away.
Up-to-date information on ambient conditions
Real-time statistics from a series of measurements
Note down your conclusions
One of ELLIPSIS’ innovative features is the ability to add a voice or text note to a series of measurements or a procedure report. Have you ever wondered if your balance is ready for work?
The Digital Weighing Auditor makes sure it is.
DWA – Digital Weighing Auditor DWA is a system that monitors:
ambient conditions (temperature, humidity, pressure, and vibration),
ELLIPSIS signals the results of the digital audit via Ambient Light, pictograms on the home screen, or a speaker.
Such a large chamber, yet still very accurate balance
Work with different labware in a chamber space of 199 x 157 x 218 mm.
Tool-free disassembly of the weighing chamber
Contaminated weighing chamber? You don’t need any tools to disassemble and clean the ELLIPSIS weighing chamber.
Don’t take our word for it
With ELLIPSIS, you can get:
Declaration of conformity
IQ, OQ, PQ documents
21 CFR Part 11 qualification
USP compliance qualification
Compliance with the latest version of the Pharmacopoeia
21 CFR Part 11
Do you work in the pharmaceutical industry? Do you need a digital signature?
We are offering the laboratory balance which as a standalone fully meets the requirements of 21 CFR Part 11/ EU GMP Annex 11.
Full data security
Have you ever failed to record the weighing result?
Pipette calibration reports
E-signed documents (21 CFR Part 11)
Weight adjustment reports
What was the value of the previous measurement?
ELLIPSIS always displays the history of the last 20 measurements on the slide-out panel. It is also here where the measurement series ready for e-signature, in accordance with 21 CFR Part 11, can be found.
If you use labware, weigh stents or filters, or want to check your pipette, use the ELLIPSIS accessories available Please call us for more info
Q & A
Do I need additional computer software to make the 5Y series fully compliant with 21 CFR Part 11/ EU GMP Annex 11?
RADWAG advanced-class products, including 5Y series balances, do not require any PC software to meet the requirements of 21 CFR Part 11/ EU GMP Annex 11. The balances are equipped with a built-in 21 CFR module, which has been repeatedly validated in the pharmaceutical industry as fully compliant with the aforementioned regulations.
On the new ELLIPSIS 5Y series balances, can I create a text/printout with any content describing my weighing process?
Yes, this is very easy with the 5Y series. Simply create a non-standard printout and fill it with content that describes your weighing process. You can also use over 400 variables to expand your printout with information from the weighing process (for example, date, sample name, net weight, sd value from a series of measurements, etc.).
Will ELLIPSIS allow me to send the measurement directly to a spreadsheet, such as MS Excel, or other word processor?
Yes, every 5Y series balance gives you the option, when connected to your computer with a USB-C cable, to use the Free Link functionality. Free Link is responsible for sending properly formatted data from the balance directly to the currently open spreadsheet.
