Top 5 Questions You Should Ask When Buying a Pipette

Are You In The Market For A... Pipette?

Pipettes can be found in almost every laboratory and, if you’re looking to buy one, there are many options— manual or electronic, single or multi-channel. Luckily, a few main considerations can help in deciding whether or not to buy the latest pipette technology.

Best practices dictate that pipettes undergo preventive maintenance and calibration at least once per year. Calibration involves dispensing set volumes of a liquid, usually water, into the weighing pan of a calibrated balance. Service personnel correct for temperature, humidity, and atmospheric pressure, and then compare the expected weight to the actual weight.

Top 5 Questions You Should Ask When Buying a Pipette

  1. What differentiates the pipette from others offered in terms of performance and ergonomics?
  2. Is the product compatible with other manufacturers’ consumables (tips)?
  3. What types of services are offered for this product? Calibration? Repair?
  4. Does the company offer application support and technical phone support before and after product purchase?
  5. What is the product life expectation? What is the product’s warranty period? If the company discontinues the product, for how many years do they provide accessories and parts for the instrument?
