WPI’s new 5 µL NanoFil™ syringe is designed for researchers who require exceptional precision when delivering ultra-low volumes in ophthalmic and neuroscience applications. Featuring a gas-tight, zero-dead-volume design and a compact format that supports comfortable single-handed operation, the syringe improves dosing accuracy, volume resolution, and reagent conservation. Researchers can maintain greater control during delicate procedures such as intravitreal, subretinal, and stereotaxic injections while minimizing tissue disruption and reducing operator fatigue. Ideal for gene therapy, optogenetics, CRISPR research, and ocular drug delivery, the 5 µL NanoFil™ syringe helps produce reliable, reproducible experimental results.

Vessel damage during small animal procedures can affect tissue viability, recovery, animal welfare, and experimental reproducibility. Fortunately, many vascular injuries are preventable through appropriate instrument selection and careful tissue handling. This article explores the most common causes of vessel damage, including excessive clamping force, repeated manipulation, poor visibility, and instrument mismatch. It also discusses how hemostatic forceps, thumb forceps, and microsurgical instruments can help preserve vascular integrity when properly selected and maintained. By combining thoughtful instrument choice with atraumatic technique, researchers can reduce tissue trauma, improve procedural consistency, and support more reliable research outcomes.

Microsurgery demands precise tissue handling, where even small technique variations can influence outcomes. This article explores four common causes of iatrogenic tissue damage: excessive clamping force, instrument-related thermal transfer, repeated tissue grasping, and poor instrument tip alignment. Readers will learn how these mechanisms contribute to endothelial injury, inflammation, tissue fragility, and compromised healing, often before visible signs of damage appear. The article also outlines practical strategies for recognizing and preventing tissue trauma through proper instrument maintenance, careful energy management, and atraumatic handling techniques. These principles help improve surgical consistency, tissue viability, and experimental reproducibility in microsurgical procedures.

WPI’s disposable scalpels come in many styles and are ideal for students, researchers, and crafters. Here we will describe some of the uses for these popular blades.

Choosing the right cell culture dish for microscopy involves four key decisions: material, objective compatibility, format, and surface coating. This guide provides a practical framework for matching dish selection to imaging technique — from widefield fluorescence and confocal to TIRF, super-resolution, and live cell time-lapse. It covers when glass bottom dishes are required versus when plastic is acceptable, how to match FluoroDish™ format to workflow requirements, and when the FD3510's unique geometry makes it the right choice for microinjection and reagent conservation. A format reference table and technique-by-technique recommendations make this a practical resource for researchers, CRO analysts, and pharma imaging scientists.

Tissue preservation is critical in research surgery, where excessive trauma can affect healing, animal welfare, and experimental outcomes. Hemostatic forceps help minimize tissue damage by providing controlled pressure, improving bleeding control, and reducing unnecessary tissue manipulation during procedures. From fine mosquito forceps used in small animal surgery to larger instruments designed for tissue bundles and vascular pedicles, selecting the appropriate hemostat can improve precision and consistency. This article explores how hemostatic forceps contribute to atraumatic tissue handling, common mistakes that increase tissue injury, and best practices for preserving tissue integrity during laboratory and research procedures.
