Frequently Asked Questions
Pipette FAQ
How often should a pipette be calibrated?
For routine laboratory use, calibration is generally recommended every 3–12 months, depending on usage frequency and quality requirements.
Can the pipette be autoclaved?
Fully autoclavable models can be sterilized at 121°C for 20 minutes. Please refer to the product manual before autoclaving.

  • Loose tip fitting
  • Damaged seal components
  • Cracked pipette tip

Replace the tip and inspect the sealing system.

Why is the pipette dispensing inaccurate volumes?

Possible causes include:

  • Incorrect pipetting technique
  • Worn piston seals
  • Damaged O-rings
  • Incompatible pipette tips

Regular maintenance and calibration can improve accuracy.

What types of pipettes are available?

Common options include:

  • Single-channel pipettes
  • Multi-channel pipettes
  • Fixed-volume pipettes
  • Adjustable-volume pipettes
Laboratory Centrifuge FAQ

Use this text to answer questions in as much detail as possible for your customers.
Why does the centrifuge vibrate excessively?

Possible causes include:

  • Unbalanced sample loading
  • Improper rotor installation
  • Damaged rotor
  • Uneven laboratory bench

Always balance samples before operation.

How often should the rotor be inspected?

Rotors should be inspected regularly for corrosion, cracks, or deformation before each use.

 

What should I do if the centrifuge does not start?

Check:

  • Power connection

Can biological samples be centrifuged safely?

Yes, provided that suitable tubes, sealed rotors, and proper operating procedures are used.

Vortex Mixer FAQ
What is a vortex mixer used for?
A vortex mixer is designed for rapid mixing of liquids in tubes, vials, and small laboratory containers.
What is the difference between touch mode and continuous mode?
  • Touch Mode: Mixing starts when the tube touches the cup head.
  • Continuous Mode: Mixing runs continuously until switched off.
Why is the mixer not rotating?

Possible causes include:

  • Power supply issues
  • Faulty switch
  • Motor malfunction
  • Internal electrical failure
Can a vortex mixer handle multiple tubes at once?
Yes. With optional tube racks or platform attachments, some models can mix multiple samples simultaneously.
Why is the vortex mixer making unusual noise?

Check for:

  • Loose accessories
