Precision and accuracy are imperative regarding liquid sample handling in the lab. Using useful tools along with the best instruments available can streamline the automated liquid handling process. There should be high standards of training for protocol and procedures in place with a concentration on safety in the lab. Read on to learn more about important liquid sample handling tools and safety tips.

Liquid Sample Handling: Safety First

One of the most important considerations when it comes to safety is the handling and storage of flammable liquids. Try to reduce the number of flammable liquids you have in the lab and keep only what you need for the job at hand. Also, only store your flammables in a UL-approved flammable storage cabinet, and be sure to place flammables on a tray when in use to avoid any spillage.

Liquid Sample Handling: Useful Tools

Depending on the experiment or purpose, different equipment and instruments are used for liquid handling solutions. Some are more simplistic, while others are used in automated liquid handling systems. You should be familiar with all equipment and a precise knowledge of how to use each piece. Some equipment includes:

  • Pipettes. These may also be referred to as pippetors or pipets. These are used in many sciences and carry liquid from one place to another. There are several types of pipettes, including electronic pipettes, single-piece types, and adjustable pipettes.
  • Cryovials. As its name suggests, this vial stores liquids at extremely low temperatures.
  • Burettes. This equipment is a cylinder-shaped glass piece with a stopcock at the bottom and measures small amounts of liquids.
  • Funnels. A funnel allows you to move liquid from one container to another without risk of spillage.
  • Centrifuge tubes. This is made of calibrated glass and is inserted into a centrifuge machine. The tube is then spun at high speeds for analysis or used for additional testing.
  • Culture tubes. Also known as a test tube, this is likely the most common piece of liquid sample handling equipment.
  • Erlenmeyer flasks or conical flasks. This flask has a cone-shaped body and stores and heats liquids. Because of its shape, it can heat liquids more quickly.

Some very common liquid handling tools include:

  • Bottles
  • Beakers
  • Evaporating dishes
  • Stir rods
  • Thermometers

Liquid Sample Handling: Tools for Automated Systems

There are also liquid sample handling tools for automated systems. While pipettes have already been mentioned, other tools can be useful in your lab, such as:

  • Pipette tips. There are different types of pipette tips that can improve pipette performance.
  • Pipette fillers. This provides a rechargeable, heavy-duty battery to extend the working life of your pipette.
  • Microplate dispensers. These work with many different types of plates and save time on manual labor in the lab.
  • Robot movers. Using these can increase efficiency in the lab.

Other automated liquid sample handling equipment includes:

  • Automated incubators
  • Channel pipetting modules
  • Automated plate sealers
  • Thermal cyclers

While this is not a complete and comprehensive list, these tools and equipment can help save time and increase efficiency in the lab.
