What we make
Range & specifications
Glass and PP dropper pipettes with nitrile, silicon, rubber or PVC bulbs, supplied as components or assembled into a bottle and cap. PP pipettes run by net length from 51 mm to 89 mm, plain or with an embossed graduation at 0.25, 0.5, 0.75 and 1.0 ml.
Why it fits as one unit
Bulb material and colour are a separate decision from the pipette, which lets a nitrile bulb sit on a glass tube, and the teat sizes for 13/425 and 15/425 are listed. Send the bottle depth and the dose you want to draw, and we return pipette length, graduation and bulb as one line.

Patents behind the design
This line sits inside a wider portfolio of 29 valid patents (invention and utility model) across spray pumps, lotion pumps, foam pumps and aerosol cans. Where a product family carries its own design patent, it is listed on the relevant page.
Every patent number links to its Google Patents record — assignee, abstract, claims, drawings and legal status — so a buyer can confirm ownership without asking for a certificate.
