Q5: How can the magnet heads be changed?
A5: By running the Change_magnet protocol under the Maintenance
menu using the Up and Down arrow keys.
Q6: How does the heating block work?
A6: The heating block is located inside the instrument and can be used
automatically during the protocol. All plates can be heated using
specially designed, interchangeable heating blocks. Any number of
heating steps can be added to the protocol. During the protocol, when
the protocol enters the heating step, the plate is automatically moved to
the dedicated heating position for heating. After the heating step, the
protocol continues automatically to the next step.
Note No cooling steps can be added.
Q7: How long does it take the heater to warm up from RT to 80
A7: The heating block warms up about 10 degrees per minute, so it will
take about 6 minutes.
Q8: What should I do if the magnets set are dirty?
A8: Wipe the magnetic rods with a soft cloth or tissue paper soaked in a
mild detergent solution, soap solution or alcohol.
Q9: What should I do if I forget to insert the tip combs into the tip comb
holder?
A9: The protocol will not start without the tip combs inserted into the
tip comb holder.
Q10: What if the magnetic particles remained in the sample well?
A10: If the starting material is too viscose, the magnetic rods will not be
able to collect the particles. Dilute the sample and check that the
sample is properly homogenized/lysed.
Adding low amounts of detergent will improve the collection of
magnetic particles as well.
Quickly centrifuge the plate to sediment the particles to the bottom of
the plate.
