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?

Plenty of discussions are happening on LabWrench all the time. We have many questions come in daily from users that are seeking advice from fellow users and lab professionals on LabWrench. Can you help any of these users find the answers they are looking for?

Thermo Scientific Harris SLT-13V-40A35
We are in USA and have a SLT-13V-40A35. What are the voltage/Amps? What are the Hz phase requirements? Does this need to be hard wired?  Advise this member.

Beckman Coulter Allegra X-15R (Centrifuge)
Centrifuge model X 15 R is giving error code I4.  Provide an explanation.

Instron CEAST Model 9340 (Impact Testing System)
When I change from metric to British units (which is what I want displayed), the graph panel shows the data compressed along the x-axis. (When it is metric, it is evenly spread across the area of the graph.) When BU is set, I have been right-clicking on the graph and using “Set manual scale” to change the range on the x-axis but it won’t stick. Alternately, when I try “Autoscale”, nothing happens at all. If I reload the data, it reverts to the data being compressed along the x-axis in BU.
Does anyone know how to use autoscale to change the x-axis scale and save it?  Respond to this member.

 Questions from the Vault

We have so many questions filling our forums that sometimes questions can be missed and go without answers. Can you help us provide answers for these users with unanswered questions?

Pipettes under control!
We buy and calibrate hundreds of pipettes per year.  We would like to make an inventory to take the pipettes management under control. Do you know of any efficient way?  Share your experience.

Pipette Calibration
How do I calibrate a Rainin pipet-plus LTS RL? I've already checked for any part problems, and I'm getting high volumes. It just need calibration. Help this member.

Missing 4x objective for Nicon Labophot 2
I've used microscopes for years but don't know about the instruments themselves. This uses E Plan lenses. Do I have to get an E Plan or can I buy a universal 4x Plan that "can be used w/Nikon, Olympus and other microscopes" according to the seller?  Provide feedback.
