Pipettes are among the most frequently handled instruments in any laboratory, and disorganised storage can contribute to safety risks and workflow delays. A structured system for storing pipettes helps protect staff from strain and cross-contamination risks while keeping testing schedules on track. Fitting benches with a dedicated pipette storage tray keeps instruments upright, ventilated and separated from general bench clutter, while stocking a reliable range of serological pipettes ensures the right tool is available when needed. This guide sets out practical steps for organising pipettes safely and efficiently across healthcare, pathology, education and research laboratories.
Why Does Pipette Organisation Matter in the Laboratory?
Disorganised pipette storage increases the risk of dropped instruments, cross-contamination between samples, and repetitive strain from awkward reaching or prolonged searching. A structured storage system reduces handling time, protects measurement accuracy and supports compliance with workplace health and safety obligations.
Safety Risks of Poor Pipette Storage
Pipettes left loose on benchtops or crowded into drawers are more likely to be knocked, dropped or damaged. Serological pipettes with sharp tips can cause puncture injuries if stored incorrectly, and glass or plastic barrels left unsupported are prone to chipping or cracking. In healthcare and pathology settings, damaged pipette tips also raise the risk of specimen contamination, which can compromise test results and patient safety.
Efficiency Losses from Disorganised Benches
Staff who cannot locate the correct pipette volume or type lose valuable time during batch testing, and misplaced equipment often leads to duplicate purchasing. Laboratories that organise pipettes by size, function and frequency of use report smoother workflow during high-volume periods, particularly in diagnostic and research environments where turnaround times matter.
What Are the Best Ways to Store Pipettes Safely?
The safest pipette storage methods keep instruments upright, separated by type, and away from moisture or direct sunlight. Purpose-built trays, wall-mounted racks and drawer inserts all reduce contact damage while making stock levels easy to check at a glance.
Using Purpose-Built Trays and Racks
A dedicated tray or rack designed specifically for pipette storage prevents rolling, reduces contact between tips, and makes daily stock checks faster. Recyclable PVC trays are easy to wipe down between uses, which supports infection control in clinical and pathology settings while also protecting delicate graduations from wear.
Separating Pipette Types by Volume and Function
Grouping pipettes by volume, whether 1ml, 5ml or 10ml, and by whether they are sterile, graduated or serological, reduces the chance of selecting the wrong tool mid-procedure. Colour-coded pipettes make this separation even faster to manage visually, particularly in busy shared laboratories where several staff use the same storage area throughout the day.
How Can Laboratories Reduce Cross-Contamination Risk?
Cross-contamination risk drops significantly when pipettes are stored in designated, cleanable containers rather than shared drawers. Assigning specific trays to specific procedures or sample types creates a clear physical barrier between clean and used equipment.
Australian competency standards for laboratory technicians identify dedicated, non-shared storage and equipment handling as a core technique for preventing cross-contamination between samples (Manufacturing Industry Skills Alliance, 2024). Applying this same principle to pipette storage, keeping sterile stock separate from pipettes in active use, and cleaning trays between batches, helps laboratories maintain sample integrity without adding extra steps to daily workflow.
How Does Pipette Organisation Support Workplace Health and Safety?
Searching for pipettes, reaching into cluttered drawers or repeatedly restocking a disorganised bench are all examples of repetitive and awkward manual tasks. Reducing these movements through better organisation lowers the risk of musculoskeletal strain over time.
Safe Work Australia identifies repetitive movement, awkward posture and sustained reaching as characteristics of a hazardous manual task that can contribute to musculoskeletal disorders (Safe Work Australia, 2016). In a laboratory context, this includes the small but frequent movements involved in locating, retrieving and returning pipettes throughout a shift. Fixed storage positions, at a comfortable working height and within easy reach, minimise these risks while also making handover between staff simpler and more consistent.
How often should pipette storage trays be cleaned?
Pipette trays should be cleaned according to the facility’s SOPs, contamination risk assessment and workflow requirements. In clinical and pathology environments, trays may require more frequent cleaning, particularly after spills, contamination events or handling of high-risk materials. Recyclable PVC trays can be cleaned according to the manufacturer’s care instructions, using compatible laboratory cleaning agents where suitable. Cleaning method and disinfectant selection should be confirmed based on the tray material and product specifications to help maintain durability and performance.
Can different pipette types share the same storage tray?
It is best practice to separate pipettes by volume, sterility and function rather than mixing types in one tray. This reduces selection errors and keeps sterile stock isolated from pipettes already in use.
Does pipette storage affect measurement accuracy?
Yes. Pipettes stored horizontally in cluttered drawers are more prone to knocks that affect tip alignment and graduation accuracy. Upright, individually supported storage helps protect pipettes from damage, contamination and unnecessary wear during daily laboratory use. Maintaining measurement reliability over the life of the instrument also depends on regular calibration, appropriate maintenance, correct handling and suitable operating conditions.
