Are your lab instruments working against 1 in 10 of your researchers?
Up to 10% of the population is left-handed, yet the vast majority of laboratory scissors and instruments are designed exclusively for right-handed use. In everyday life, that's an inconvenience. In a precision research environment, it's a variable that affects cut quality, technique consistency, and researcher fatigue.
The mechanics are straightforward: standard scissors are designed so that a right-hand squeeze drives the blades together. A left-hand squeeze does the opposite and causes the blades to splay apart rather than shear cleanly. Left-handed researchers compensate instinctively, often without realizing the toll it takes over a long session at the bench.
The good news? The solutions are simple and affordable:
• Dedicated left-handed scissors with mirrored blade geometry allow for natural, precise cutting actions
• Spring scissors are fully ambidextrous by design, and an excellent choice for fine dissection work regardless of hand dominance
We've put together a full article covering the science behind scissor mechanics, the instruments most affected by handedness, and why inclusive instrument selection matters for research quality.
WPI carries a wide range of spring scissors and left-handed laboratory scissors, because no researcher should be fighting their instruments.

Not all glass bottom dishes are the same, and the right choice depends on more than just material.
Technique, objective type, cell model, field of view, media volume, and workflow geometry all factor into the decision. A dish that's optically correct for confocal may be the wrong format for microinjection. A standard 35mm dish may not provide enough surface area for tiled acquisition or organoid culture.
We built a practical selection guide that maps key variables to a concrete recommendation, including a technique-by-technique breakdown covering widefield fluorescence, confocal, TIRF, super-resolution, and live cell time-lapse, and a format reference table for matching dish geometry to workflow.
There's also a section on the FD3510, a 35mm dish with a 10mm angled well specifically engineered for microinjection workflows and reagent conservation, that's worth reading if you're doing intracellular injection, IVF, or working with expensive media where volume matters.
If you've ever chosen a dish by default rather than by design, this guide gives you a better framework.

Even the most skilled researcher can unintentionally cause tissue trauma if the wrong instrument is used or used incorrectly.
Hemostatic forceps do far more than control bleeding. They help minimize tissue manipulation, provide consistent clamping pressure, improve visibility, and support more precise surgical workflows. When working with delicate tissues in small animal surgery, neuroscience research, or tissue harvesting procedures, these seemingly simple instruments can have a significant impact on both outcomes and reproducibility.
Our latest article explores how proper hemostat selection and technique can help preserve tissue integrity and support refinement principles in research surgery.
