Stuart Herskovitz established his unique Qosina company in 1980 to serve medical device companies by providing stock components. Companies purchase from Qosina to eliminate the cost of tooling their own components and to receive immediate delivery from inventory. This particular approach is useful to companies of all sizes, but has proven especially effective for small to mid-range manufacturing companies, as evidenced by Qosina's broad customer base cultivated over the years. 

Our company’s offering has grown from four pages of components in flier format to a 400+ page catalog featuring thousands of stock items. We offer customer-centric solutions, such as providing samples for testing and sourcing items not already in Qosina's comprehensive catalog. 

Save time and money by purchasing components from Qosina. Our thousands of SKUs provide an essential inventory management solution.

We can provide Kanban replenishment service based on your real time need. Place a "blanket" Kanban order and let Qosina release your parts as you need them. This service can cut inventory levels, shorten production lead times, reduce required manufacturing space and ensure orderly material flow.

Stock components can eliminate the cost and time of creating a mold since one may already exist. However, if the item you require is not in our inventory, we will work to develop the part to your exact specifications. Slight alteration of an existing mold can be a cost-effective way to create a new part to meet your requirements. Fill out a sourcing request form and we will work to develop a part to your exact specifications.

We support your production requirement with just-in-time delivery from our ISO 9001, ISO 13485 & ISO 14001 Registered 95,000 square foot climate-controlled facility with a Class 100,000 Cleanroom.
