Micropipette Storage and Cleaning: A Quick Maintenance Guide

Blog Article

Any laboratory needs precision, and well maintained equipment is essential to that precision. A basic instrument for measuring and moving tiny amounts of liquid, the micropipette needs constant maintenance to remain accurate and useful. In addition to reducing the micropipette's lifespan, improper cleaning or negligent storage might produce inconsistent experimental findings. Following the proper maintenance procedures can make all the difference, regardless of your level of experience as a lab technician or your level of inexperience as a student.

Why Micropipette Maintenance Matters

Being a sensitive device, a micropipette needs to be calibrated precisely and have clean internal parts in order to work properly. Dust, moisture, or residue buildup can contaminate samples or have an impact on the pipette's seal and piston action. The tool's operating life may be increased, cross-contamination risk can be decreased, and volume accuracy can be maintained with regular cleaning and secure storage.

Cleaning Your Micropipette: Simple but Crucial

Your lab's protocol should include routine micropipette cleaning. If it has come into touch with biological materials, begin by cleaning the outside using a moderate disinfectant and a lint-free cloth. Use of harsh chemicals should be avoided as they can damage the labeling or outside surface.

Following the manufacturer's instructions, disassemble the micropipette for a more thorough cleaning. The majority of micropipettes enable the lower shaft and piston assembly to be removed. Use a non-abrasive detergent or 70% ethanol to gently clean these areas. Before reassembling, give them a good rinse and let them dry fully.

Particularly with electronic or adjustable types, avoid wetting the entire micropipette as this could harm internal parts. Additionally, unless a part is marked as autoclavable, never autoclave it.

Storage Practices That Protect Your Micropipette

Cleaning is crucial, but so is proper storage while not in use. A specialized pipette stand should be used to store a micropipette upright. By keeping liquids out of the pipette's body, this posture lessens the mechanical strain on its internal components.

The micropipette should not be placed flat on a bench where it could roll, be knocked off, or come into contact with something corrosive. Additionally, to avoid warping or condensation inside the pipette, keep it out of extremely hot or cold environments.

Make it a practice to keep your micropipette in a clean location, away from any possible pollutants, if your lab works with a variety of chemicals and reagents. By doing this, exposure to any fumes or residues that could get into the device is reduced.

When and How to Schedule Regular Servicing

A micropipette needs to be calibrated and maintained by a professional on a regular basis, even with the best of care. Depending on usage frequency, service should ideally be performed every six to twelve months. More frequent inspections may be necessary in high-use labs to make sure the pipette is still accurately dispensing volumes.

Using gravimetric techniques, some labs do internal checks by contrasting the actual dispensed volume with the predicted values. For long-term accuracy, however, expert calibration by accredited service providers is advised, particularly in controlled settings like research or pharmaceutical labs.

Common Mistakes to Avoid

If the micropipette is not made for it, do not use it for a variety of volumes. Excessive range extension may result in harm or inaccurate results. Pipette tips should also not be firmly attached or removed as this can damage the internal sealing system or nozzle.

Storing a micropipette with a used tip still attached is another frequent error. Contamination may result from this, particularly if any leftover liquid evaporates and enters the shaft.

The micropipette should always be handled cautiously. Even a single drop can disrupt the internal calibration and reduce its accuracy. It is best to recheck a pipette's function or send it for calibration before using it again after an unintentional drop.

Final Note

A properly kept micropipette improves the overall integrity of your lab work in addition to making research cleaner. Long-term problems and expensive repairs can be avoided by allocating a few minutes each day for appropriate cleaning and according to storage guidelines. You can make sure that your micropipette will continue to provide precise, reliable results for many years to come by giving it the care and attention it needs.
