MG Chemicals 814-50, Rectangular Foam Swabs, Single Sided, 50 Pack, Case of 5 Packs
MG Chemicals 814-50, Rectangular Foam Swabs, Single Sided, 50 Pack, Case of 5 Packs
MG Chemicals 814-50 rectangular foam swabs combine an oversized, absorbent urethane foam head with a rigid polypropylene handle for controlled cleaning of parts and equipment. The large single-ended tip provides a broad contact area for wet wiping with isopropyl alcohol (IPA) or DI water while resisting smearing and streaking. Supplied as 50 swabs per bag, with five packs in this case listing.
Best Uses / Applications
For electronics maintenance, assembly support, precision parts cleaning and surface hygiene sampling. The rectangular head suits larger accessible surfaces where an oversized foam tip is more useful than a narrow applicator. Verify the cleaning fluid and swab are appropriate for the surface and your contamination-control process.
Key Features
- Shred-resistant, 100% urethane foam head with 100 PPI porosity.
- Highly absorbent hydrophilic tip with fast wet-wipe characteristics.
- Rigid polypropylene shaft for controlled pressure.
- Large contact area for IPA or DI-water cleaning.
- Single-ended rectangular format resists smearing and streaking.
- Manufacturer lists Class 100–1000 use; confirm suitability for your facility rather than treating this as a sterility claim.

Use and Disposal

Follow your facility's disposal rules for the swab and any absorbed chemical. Although manufacturer copy describes the shaft as burnable, do not treat this as permission to burn contaminated swabs.
Frequently Asked Questions
How many swabs are supplied?
Each 814-50 bag contains 50 swabs. This case-of-five-packs listing contains 250 swabs in total.
Can they be used with isopropyl alcohol?
Yes. The manufacturer identifies IPA and DI water for cleaning applications. Verify compatibility with the surface being cleaned.
Are the swabs ESD safe?
The 814-50 source does not identify it as an antistatic swab. The cleaning-swabs data sheet specifically associates ESD-safe wording with 812AS; use a verified antistatic option when required.
Are they sterile?
The verified sources do not identify 814-50 as sterile. Do not use Class 100–1000 wording as proof of sterility.
What length should I use for procurement?
The TDS lists 5.5 in overall, 0.9 in tip and 4.5 in handle. Product-page prose says a 5 in shaft, so confirm with MG Chemicals if an exact handle dimension is critical.
What distinguishes this from a narrow foam applicator?
Its oversized rectangular foam head provides a larger contact area for accessible surfaces. Choose a narrower format when access or feature size requires it.
