Sample Measurement Workflow
1.
Switch on Photopette.
2.
Start the Photopette app; enable Bluetooth.
3.
Under “Device” connect with Photopette
.
4.
Under “Measurement type” select “Wavelength Type” or “Application Type”. Use vortexer to
mix your sample to achieve homogeneous sample.
5.
Attach the CuveTip onto the tip of the device. Ensure it sits tightly on the stem.
6.
Press “START MEASUREMENT”
.
7.
Insert the CuveTip into your blank solution or blank buffer or distilled water. Make sure no
bubble stays in the cavity of the CuveTip. Please read our Technical Note “How to use the
CuveTip Correctly” available at the Tip Biosystems webpage at
8.
Press “AUTO ZERO” on the app or press the top button on the Photopette device.
9.
Remove CuveTip from the blank. In case you sample has a large volume of more than 10 mL
you can directly insert the same CuveTip into your sample and move the tip for 10 seconds to
exchange any blank solution residues with sample. For small sample volumes, tap the CuveTip
onto a clean lab paper to remove the blank by capillary force first before transferring into the
sample.
10.
Press “MEASUREMENT”
and the absorbance values or concentrations will be shown directly
on the screen.
11.
You can use the same CuveTip to perform additional measurements.
NOTE:
Do not overfill the sample vial. This is to prevent samples from seeping in from the top of the
sample vial.
NOTE:
Check the chemical compatibility chart for the compatibility of the sample solvent or solution
you are using. The information is available in the annexure of this manual and on the technical
information of the website. Please contact us at [email protected] if your solvent of your
sample is not listed on the chart.
Sample Handling Tips
•
It is important to mix or vortex every sample right before measurement, if needed, to
ensure homogeneity.
•
The minimum volume that can be used for sample measurement is 45 µl and can be reuse
if it is inserted into the tip cavity using a micropipette.
•
Proper fitting of the CuveTip™ is important to ensure accurate
measurement.
•
In most cases, a laboratory clean wipe is sufficient to clean the device.
•
Please avoid touching the tip of the device.
