Menda 4 oz Impact-Resistant Amber Glass Pure-Touch Dispenser with PFA Stem – 35741
Protect the purity of your cleaning liquids while enjoying convenient one-handed dispensing with this Menda Pure-Touch dispenser. Featuring a 4 oz amber glass bottle, protective plastisol safety coating, stainless steel pump, and chemically resistant PFA stem, this refillable dispenser is designed for demanding laboratory, electronics, and industrial cleaning applications.
The Pure-Touch pump features a patented purity protector that prevents liquid from returning to the bottle after dispensing. This non-return design helps protect the remaining contents from contamination, making it especially useful for applications where maintaining liquid cleanliness is important.
Each press delivers approximately 0.2 cc of liquid into the pump's dispensing well. Simply press a compatible cotton swab, cleaning pad, or wipe against the pump to obtain a controlled amount of liquid without pouring from an open container.
The amber glass bottle offers excellent compatibility with many liquids that cannot be stored in conventional plastic bottles. Its translucent amber color also helps protect light-sensitive contents while allowing the remaining liquid level to be viewed.
A protective plastisol coating surrounds the glass bottle, providing improved grip and increased resistance to impact and fall damage. If the bottle breaks, the coating helps contain broken glass and liquid, reducing the risk of injury and allowing time for appropriate cleanup.
The pump includes a PFA (perfluoroalkoxy) stem, a chemically resistant fluoropolymer designed for demanding liquid-handling applications. PFA offers resistance to many acids, bases, and industrial solvents, making it suitable for applications where conventional stem materials may not provide adequate compatibility.
A hinged pump lid with a cam-lock mechanism stays open during dispensing and closed when the dispenser is not in use. The lid helps reduce odors and protects the dispensing well from unnecessary exposure.
Manufactured in the United States, Menda 35741 combines non-return dispensing, chemical resistance, and safety-coated glass construction for professional workstations.

Pure-Touch Non-Return Pump
The Pure-Touch pump is designed to help protect the purity of the liquid remaining inside the bottle.
Its patented purity protector prevents liquid from returning to the container after it has been dispensed into the pump well.
This is an important distinction from conventional return-flow dispensing pumps.
With a return-flow design, unused liquid may drain back into the bottle after contact with the dispensing surface.
The Pure-Touch mechanism prevents this reverse flow, helping reduce the possibility of contaminants entering the remaining liquid.
This makes the dispenser useful for precision cleaning, laboratory work, and other applications where maintaining liquid cleanliness is important.
Patented Purity Protector
The patented purity protector is a defining feature of the Pure-Touch pump.
By preventing liquid from flowing back into the bottle, it helps protect the contents from contamination introduced during dispensing.
This is especially useful when swabs, pads, or wipes repeatedly contact the pump surface.
The non-return design helps maintain a cleaner working supply of liquid throughout repeated use.
The purity protector does not make the dispenser sterile or eliminate the need for proper cleaning and handling procedures.
Stainless Steel Pump Construction
The pump is manufactured from stainless steel for durability and repeated use.
Its precision-machined valves are designed to provide smooth, consistent operation.
The push-down mechanism allows liquid to be dispensed with one hand, making it convenient for technicians who frequently alternate between cleaning and handling workpieces.
The stainless steel construction is suitable for many demanding dispensing applications.
Always verify compatibility with the specific chemical being used.
Controlled 0.2 cc Dispensing
Menda specifies that the Pure-Touch pump dispenses approximately 0.2 cc of liquid per press.
This small volume is convenient when only a limited amount of cleaning liquid is required.
Controlled dispensing helps reduce unnecessary liquid consumption and avoid oversaturating cleaning applicators.
The actual quantity delivered may vary with the liquid's viscosity, pump condition, and operating technique.
The dispenser is intended for convenient application rather than calibrated volumetric measurement.
Impact-Resistant Amber Glass Bottle
The bottle is manufactured from translucent amber glass.
Glass provides broad chemical resistance and is suitable for many liquids that may attack or permeate conventional plastic containers.
The amber color helps protect compatible light-sensitive liquids from ambient light.
Unlike opaque containers, the translucent glass still allows the remaining liquid level to be checked.
The bottle is particularly useful where chemical resistance and convenient dispensing are both important.
Protective Plastisol Safety Coating
A protective plastisol coating surrounds the glass bottle.
This coating improves grip and provides additional resistance to impact and fall damage compared with uncoated glass.
If the bottle breaks, the coating helps contain glass fragments and liquid.
This can reduce the risk of injury and provide time for appropriate cleanup and disposal.
The coating does not make the bottle unbreakable or completely leakproof.
Inspect the bottle and coating regularly and replace the dispenser if damaged.
Chemically Resistant PFA Stem
The pump features a stem manufactured from PFA, or perfluoroalkoxy.
PFA is a fluoropolymer known for excellent chemical resistance and stability.
It is resistant to many acids, bases, and common industrial solvents.
The material also offers low-friction and nonstick characteristics that are useful in fluid-handling applications.
This makes the PFA stem suitable for demanding chemical dispensing environments.
However, chemical compatibility must still be verified for the complete dispenser, including the glass bottle, stainless steel pump, seals, and protective coating.
Amber Glass for Light-Sensitive Liquids
The amber glass bottle helps reduce exposure to ambient light.
This can be useful for compatible liquids that are sensitive to light during storage or use.
The translucent glass also allows technicians to check the remaining liquid level without opening the container.
The degree of light protection depends on the chemical and the wavelengths to which it is sensitive.
Follow the chemical manufacturer's storage recommendations for liquids requiring specific light protection.
Cam-Lock Hinged Lid
The pump includes a hinged lid with a cam-lock mechanism.
The lid is designed to remain open during dispensing and closed when the bottle is not in use.
Closing the lid helps reduce odors and limits unnecessary exposure of the dispensing well.
It also helps protect the pump surface from dust and other contaminants.
The cam-lock lid is not a transport-locking pump mechanism.
Keep the dispenser upright and follow appropriate chemical storage and transportation procedures.
Silicone- and Latex-Free Pump
Menda specifies that the Pure-Touch pump contains no silicone or latex.
This is useful for applications where these materials are undesirable due to process or contamination-control requirements.
The dispenser may be suitable for certain clean work environments and precision manufacturing applications.
Always evaluate the complete dispenser against the requirements of the specific process.
Pure-Touch vs. One-Touch
Menda offers both Pure-Touch and One-Touch dispensing pumps.
Pure-Touch: Features a non-return purity protector that prevents dispensed liquid from returning to the bottle.
One-Touch: Uses a return-flow design that allows unused liquid in the pump well to drain back into the bottle.
Both designs provide convenient one-handed dispensing.
Pure-Touch is the better choice when preventing return-flow contamination is an important requirement.
Chemical Compatibility and Safe Use
The amber glass bottle and PFA stem provide broad chemical resistance, but no dispenser should be assumed compatible with every chemical.
Before filling, verify compatibility with all wetted components, including the pump and seals.
For flammable liquids, follow appropriate ventilation, ignition-source control, and workplace safety procedures.
Use suitable personal protective equipment and consult the chemical manufacturer's Safety Data Sheet.
The dispenser is not specified as a static-dissipative or conductive ESD-safe container.
For applications requiring ESD-protective dispensing equipment, select a dispenser with appropriate electrical characteristics.
Care and Maintenance
Keep the pump and bottle clean to maintain reliable operation.
Inspect the glass and plastisol coating regularly for cracks, cuts, deterioration, or other damage.
Check that the pump operates smoothly and that the hinged lid closes properly.
Avoid mixing incompatible chemicals or introducing contaminants into the bottle.
Use cleaning methods compatible with the glass, coating, pump, and stem.
Keep the contents clearly identified according to workplace labeling requirements.
Replace the dispenser if the bottle or coating becomes damaged or the pump no longer operates correctly.
