Microinjection Dosing Variability: Four Mechanical Causes (and How to Eliminate Them)
Microinjection accuracy becomes more difficult at sub-microliter volumes because small mechanical inconsistencies can change the delivered dose. Dead volume, trapped air bubbles, micro-leaks, plunger behavior, and manual technique differences all contribute to variability between injections and between users. A true gas-tight, zero-dead-volume syringe system helps maintain stable pressure and reduces sample loss, improving confidence that what you load is what you deliver. For repeatability-focused workflows, pairing the syringe with a microinjection pump can further standardize flow rate and volume, producing more consistent dosing outcomes across sessions and experiments.

WPI's NanoFil: Gas Tight Injection System in Animal Research
WPI’s NanoFil™ is a gas-tight microliter injection system for small-animal research that supports needles down to 36 gauge. Its ultra-low dead volume enables direct sub-microliter injections without oil backfilling, and a patented silicone gasket allows quick needle switching with minimal sample loss. Compatible with GC/CE capillaries and various tubing, it offers blunt and unique 25° tri-surface beveled needles (26–36G) that reduce tissue damage and improve durability. The system is widely used for precise tissue injections, including ophthalmic applications, and is supported by application kits and peer-reviewed studies.

The Hidden Costs of Improper Surgical Instrument Handling in Research Laboratories
Improper handling of surgical instruments in laboratory settings can compromise research quality, instrument performance, and experimental reproducibility. Precision instruments used for dissection, microsurgery, and animal research are especially vulnerable to mechanical damage, loss of sterility, and material degradation when mishandled. These issues can lead to increased costs, inconsistent results, and reduced procedural accuracy. By adopting proper handling, cleaning, sterilization, and storage practices, laboratories can extend instrument lifespan and maintain reliable performance. Choosing high-quality, research-grade surgical instruments and training staff on correct handling techniques helps protect both scientific outcomes and long-term laboratory investments.

How to Store Petri Dishes: 10 Best Practices for Lab Sterility and Coating Integrity
Proper storage and handling of petri dishes is a simple but critical part of maintaining sterility, surface integrity, and reproducible results in any research lab. Dust, humidity, scratches, or premature opening can compromise cultures long before they reach the incubator or microscope. Whether you’re using standard culture dishes, ECM-coated formats, or advanced glass-bottom dishes for imaging, following a few key best practices helps protect your samples and ensure consistent performance. This guide walks through the top tips for storing petri dishes of all types, with notes for coated and glass-bottom formats that require additional care.

Why Titanium Surgical Instruments are the Premium Choice for Researchers
When you spend hours at the bench or under a microscope, the smallest details in your tools make the biggest difference. The weight of your forceps, the glare from a light, the feel of a pair of scissors after repetitive use. Everything adds up. Choosing the right material isn’t just a matter of preference. It directly affects comfort, accuracy, and long‑term success in the lab.

How Long Taper Tips Reduce Sample Loss in Solution
You've calibrated your pressure settings perfectly, your timing is precise, yet you're still watching expensive reagents leak into the bath solution during microinjection. Sound familiar? This frustrating scenario plays out in labs worldwide, often leading researchers to question their pump settings or injection protocols. But after years of troubleshooting with scientists using WPI's next generation microinjection systems, one critical factor emerges repeatedly: tip geometry.
