Custom Cleaning Brush
45mm PA66 Lab Bottle Brush
45mm PA66 Lab Bottle Brush is built for Laboratory Glassware Cleaning where the brush must enter or follow glass bores, tapered walls, and bulb sections. Head size, working length, stem flexibility, and fill are selected to loosen reagent film, precipitate, and powder without losing access or control.
Product Features
45 mm cylindrical head cleans laboratory bottles and small flasks — The brush reaches sidewalls and the base.
PA66 bristles provide resilient general-purpose cleaning — Suitable for residue, film, and loose deposits.
Flexible neck options follow bottle shoulders — The head can contact curved transitions.
Protected or fan tip reaches the bottom — End finishing reduces scratching.
Long handle keeps hands outside the vessel — Twisted or molded stems can be supplied.
Working length, PA66 stiffness, head profile, stem, tip, and handle can be customized.
Product Overview
45mm PA66 Lab Bottle Brush uses a working section shaped around the available opening, depth, and internal profile. It contacts glass bores, tapered walls, and bulb sections to remove reagent film, precipitate, and powder; the access path and minimum clearance determine whether the brush needs a rigid stem, a flexible extension, a tapered head, or a stepped cleaning section. The brush must reach the full vessel length without scratching glass or striking the base with exposed wire.
Key dimensions start with Brush head diameter 45 mm, Brush head length 120 mm, and Handle length 220 mm. The structural layout follows the bottle & container brush category. The specified interface is fixed. PA66 Nylon are the principal material directions in the current specification. Set the handle and head proportions around the working distance, access angle, and the level of contact control required.

Application Areas
45mm PA66 Lab Bottle Brush is primarily mapped to Laboratory Tube Cleaning. When adapting this brush to another job, confirm the workpiece surface, how debris will leave the area, and the required finish.
- Use for Laboratory Glassware Cleaning
- Match contact to surface risk: Controllable
- Use with Water / Neutral Detergent / Alkaline Cleaner
- Confirm interface and clearance before production.
Selection Guidance
Structure fit
Match the bottle & container brush geometry to glass bores, tapered walls, and bulb sections, the available access, and manual operation. Confirm Brush head diameter 45 mm, Brush head length 120 mm, and Handle length 220 mm against the complete working envelope before finalizing the brush.
Contact material
Choose from PA66 Nylon according to the behavior of reagent film, precipitate, and powder, the surface sensitivity, and any wet, chemical, temperature, or hygiene requirements. Do not choose stiffness from the material name alone. Filament size, free trim, and density control the final contact.
When to use another solution
For 45mm PA66 Lab Bottle Brush, use another cleaning method when reagent film, precipitate, and powder cannot be released by controlled filament contact, when glass bores, tapered walls, and bulb sections cannot tolerate the selected contact material, or when the access path prevents safe engagement and residue removal.
