Mosquito Hemostat (Halsted)
Alloy / Material: Surgical Stainless Steel (Inox) Length: 12 cm Jaw Shape: Straight Jaw Pattern: Transverse serrations, full length Lockable: Yes (ratchet)

Mosquito Hemostat (Halsted)
The Halsted-Mosquito Hemostat is a small, fine-tipped locking clamp used for hemostasis, vessel occlusion, and tissue retention during small animal surgery. The transverse-serrated jaws and ratchet lock allow you to clamp bleeders and tissue and leave the instrument in place while you continue the procedure. At 12 cm with a slim straight jaw, it is the standard hemostat across rodent surgical workflows.

Fine Science Tools microsurgery instruments — including forceps, scissors, and surgical clips — are standard in animal surgery labs worldwide. They are cited across thousands of neuroscience, physiology, and pharmacology studies involving rodent surgeries, stereotaxic procedures, and tissue preparation.
What is the Mosquito Hemostat used for in animal research?
The Halsted-Mosquito Hemostat is used for hemostasis, vessel occlusion, and tissue retention during small animal surgery. The ratchet lock allows you to clamp tissue or bleeders and leave the instrument in place while continuing the procedure, freeing both hands for further work.
What material is the Mosquito Hemostat made from?
The Mosquito Hemostat is manufactured from high-grade surgical stainless steel (Inox), providing excellent corrosion resistance, durability, and autoclave compatibility.
Is the Mosquito Hemostat autoclavable and reusable?
Yes. The Mosquito Hemostat withstands standard autoclave cycles (121 °C, 15 min) and can be reused across many procedures. The ratchet mechanism should be inspected periodically to ensure proper locking.
Which animal species is the Mosquito Hemostat appropriate for?
The 12 cm slim-jaw Mosquito Hemostat is dimensioned for small animal surgery on mice and rats, matching the anatomical scale needed for delicate vessel and tissue handling.
What is the difference between the Mosquito Hemostat and a larger Halsted hemostat?
The Mosquito Hemostat (13008-12) has very fine, slim jaws optimised for the smallest vessels and delicate tissue in rodent surgery. Standard Halsted hemostats and larger Kelly or Crile patterns have wider jaws better suited to thicker tissue or larger animal models. For rodent microsurgery and small vessel work, the Mosquito Hemostat is the standard choice.
