Maintenance
Whom to contact if I have problems or questions about measurements?
Problems or questions about measurements and applications can be solved by using the supplied user manual. If you have any further questions, please contact our support team by e-mail (support@anvajo.com).
What happens if the fluidlab gets in contact with water?
The device is not waterproof and should only be wiped dry with a soft microfibre cloth or, in a laboratory environment, with a soft disposable paper cloth. The following video explains the cleaning of the fluidlab R-300 in detail.
What happens if sample fluids enter the measuring chamber?
The measuring chamber can be cleaned using the cleaning swaps supplied. For persistent dirt, the cleaning sticks can be moistened with 99% isopropanol beforehand. In the following video the cleaning of the measuring chamber is explained in detail.
Analysis
What is the technology used in the fluidlab R-300?
The fluidlab R-300 combines the two central laboratory technologies "spectrometry" and "cell counting" in one device. The anvajo technology is based on the holographic microscopy method. The optical signal is processed by anvajo's mathematical reconstruction software. Machine learning methods, such as Deep Neural Networks, then ensure accurate counting and classification.Besides the microscope, the fluidlab R-300 is also the smallest available spectrometer. The spectrum can be recorded between 375 nm and 700 nm, with a spectral resolution of less than 2 nm. Full optical transmission and absorption measurements can thus be performed without any problems.
How capable is the spectrometer?
Our spectrometer is linear in the value range 0 - 2.5 with a photometric accuracy of 0.01 or 1 %. The spectrum can be captured between 375 nm and 700 nm, with a spectral resolution of less than 2 nm. Further information can be found in the performance report of the spectrometer.
How capable is the Cell Counter?
Our Cell Counter shows a high correlation (99% accuracy, coefficient of determination R²=0.9956) both with the manual method (Neubauer chamber) and with established automated cell counters.
Can the viability be measured staining-free?
The determination of viability is performed with the fluidlab R-300 staining-free. Cytotoxic effects are eliminated and pre-analytical steps are reduced. This saves valuable time during preanalytics, increases the stability of cells and avoids contact with harmful staining materials. The differentiation of dead and living cells works based on our innovative optics identifying the refractive index of cells. The adequate visualisation of the viability application, can be found in our product video.
How long does the cell counting with the fluidlab R-300 take?
Robust and fast image signal processing and data-parallel operations combined with high computing power enable the automatic cell counting to be performed within 60 seconds.
What size and type of cells can be measured by the Cell Counter?
The Cell Counter can count cells between 3 μm and 80 μm. Among other things, the number of primary cells, yeast cells or algae can be determined. The viability can be determined for cells between 8 μm and 80 μm.
Which cell types can be analysed with the fluidlab?
Our neuronal networks have been trained with a representative number of cell forms, whereby they have learned to generally differentiate cells from impurities. This has been validated with the following cell types:
Usability
Which sample carriers can be used?
With a flexible adapter system, the fluidlab R-300 supports both standard cuvettes for spectrophotometric measurements and glass sample carriers of different layer strengths for automatic cell counting and staining-free viability determination.
When should I use which sample carrier?
Cuvettes can be used exactly the same way in our fluidlab R-300 according to their standard use in photospectrometers. For cell counting applications, we recommend using the acella 100 (20 μl chamber volume, 100 μm chamber height) . For suspensions with small cells at the upper concentration limit, we recommend using a smaller sample carrier (acella 50 or acella 20). If you are not sure which acella is the right one for your application, please contact our customer service agents at support@anvajo.com.
Is maintenance or calibration required for the fluidlab R-300?
The fluidlab R-300 is delivered factory-calibrated and does not require maintenance.
What are possible applications for the fluidlab?
The combination of spectrometer and cell counter allows a wide range of applications. This can be summarized in the following four fields:
- Research: University institutes, institutes for basic and applied research, cell culture laboratories
- Industry: Chemical, pharmaceutical and biotechnology companies
- Environmental analysis: Ministries of the environment, environmental and consumer protection offices, sewage treatment plants
- Food & Beverages: breweries, institutes for food quality, consumer protection agencies
Where is the measurement data saved?
The fluidlab R-300 has an internal memory that can store at least 500 spectrometric measurements and 500 cell counts. Via the start menu you have access to measurement results and can recall and edit them at any time.
Is my measurement data safe?
Please ensure that you only connect the fluidlab R-300 to trustworthy networks ( Wi-Fi ) that are protected by firewalls from unauthorized access from the Internet. Make sure that data is only released and received with devices that are trustworthy and properly secured. anvajo does not collect personal data and is not responsible for the loss, interception or misuse of data sent or received by the wireless communication methods of the device.
How can I install new updates for the fluidlab R-300?
If your fluidlab R-300 is connected to the Internet, the system automatically checks for software updates. If a new update is available, this is indicated by a green dot in the main menu. Open the main menu and select the menu item "Updates". If an update is available, you can install it. This process may take a few minutes. The installation is completed after an automatic restart of the system.
Can the touch screen be controlled with a pen or with laboratory gloves?
The capacitive touch screen can be operated with a touch screen pen as well as with gloves. In a laboratory environment, we recommend the use of gloves when using the fluidlab R-300 to avoid contamination of the instrument.
Can I transfer the measurement results to my computer?
At the moment the fluidlab R-300 has no network access for data transmission. However, we are working on a software solution for the PC that will allow data to be transferred.
How long does the battery of the fluidlab R-300 last?
The battery life is indicated with 5 hours. Battery specifications depend on network configuration and many other factors. The battery life may vary depending on use and settings.
