Netgut — Plain & Chromic Catgut Sutures

Natural absorbable collagen monofilament sutures designed for high knot security, smooth tissue passage, and predictable enzymatic digestion across general and specialized surgery.

Absorbable Natural Collagen Suture

Netgut — Catgut Plain & Chromic

High-Purity Bovine Collagen Monofilament

Netgut is a natural absorbable surgical suture processed from purified collagen derived from the submucosal layer of bovine intestines. Available in Plain (natural tan) for rapid tissue healing and Chromic (brown) treated with chromic salt solutions to retard enzymatic degradation, providing extended tensile strength retention for critical soft-tissue approximation.

Technical FAQ

Catgut Suture Sourcing Questions

Direct answers for hospital procurement teams, tender officers, and OEM distribution managers.

What is the key difference between Plain Catgut and Chromic Catgut sutures?
Plain Catgut is untreated purified collagen that absorbs rapidly via enzymatic digestion within 50 to 70 days, ideal for fast-healing tissue. Chromic Catgut is treated with chromic salt solution to delay enzymatic degradation, extending tensile strength retention up to 14-21 days and complete absorption to 90 days.
Are Suture Planet Netgut Catgut sutures compliant with international USP standards?
Yes, Netgut sutures strictly comply with United States Pharmacopeia (USP) and European Pharmacopoeia (EP) monograph standards for natural absorbable surgical sutures, manufactured under ISO 13485:2016 and WHO-GMP conditions.
Can global distributors order private label or OEM customized Catgut suture specifications?
Yes, we support full OEM and private-label manufacturing for international medical importers, including customized needle-thread combinations, USP sizes from 6-0 to 2, custom thread lengths, and branded foil packaging with UDI barcodes.
What packaging and shelf-life assurances are provided for export orders?
Netgut sutures are individually packed in aluminum foil primary packs with fluid preservation medium to maintain collagen flexibility, placed inside secondary peel-open pouches, and EO sterilised to a Sterility Assurance Level (SAL) of 10⁻⁶ with a 5-year shelf life.
