Menda 4 oz Impact-Resistant Amber Glass Pure-Take Locking Dispenser with PFA Stem – 35742

Keep compatible cleaning liquids and solvents conveniently accessible with this 4 oz amber glass dispenser featuring Menda's locking Pure-Take pump, protective plastisol safety coating, and chemically resistant PFA stem. Designed for professional liquid-handling applications, it combines controlled one-handed dispensing with a non-return purity protector and a locking mechanism for secure storage and transport.

The Pure-Take pump is designed to prevent liquid from flowing back into the bottle after dispensing. Its patented purity protector helps maintain the cleanliness of the remaining liquid, making this dispenser especially useful for precision cleaning, laboratory work, electronics maintenance, and applications where contamination control is important.

Unlike standard nonlocking pumps, the Pure-Take mechanism can be secured when the dispenser is not in use. When properly engaged, the locking pump is designed to prevent leakage, making the bottle convenient for technicians who move between workstations or carry compatible liquids in service kits.

The amber glass bottle offers excellent chemical resistance and is suitable for many liquids that may not be compatible with conventional plastic containers. Its translucent amber color also helps protect light-sensitive liquids while allowing the remaining contents to be viewed.

A protective plastisol coating surrounds the glass bottle, improving grip and increasing resistance to impact and fall damage. If the glass breaks, the coating helps contain fragments and liquid, reducing the risk of injury and allowing time for appropriate cleanup.

The stainless steel pump dispenses approximately 0.2 cc of liquid per press, allowing controlled application to cotton swabs, cleaning pads, wipes, and other compatible applicators. Its one-handed operation eliminates the need to pour directly from an open container.

A PFA (perfluoroalkoxy) stem provides excellent resistance to many industrial solvents, acids, and bases. This fluoropolymer material is particularly useful for demanding chemical-handling applications where conventional stem materials may not offer adequate resistance.

Manufactured in the United States, Menda 35742 provides a convenient combination of chemical resistance, contamination protection, impact-resistant glass construction, and secure locking operation.

Pure-Take Locking Pump

The Pure-Take pump combines two important features: a locking mechanism and a non-return purity protector.

The locking mechanism allows the pump to be secured when the dispenser is not in use.

When properly engaged, the pump is designed to prevent leakage, making it convenient for storing and transporting compatible liquids.

The non-return purity protector prevents liquid from flowing back into the bottle after it has been dispensed.

Together, these features provide controlled liquid application, contamination protection, and more secure storage.

The Pure-Take design is particularly useful for technicians who move between workstations or need to keep a small quantity of compatible solvent in a portable service kit.

Patented Non-Return Purity Protector

The patented purity protector is a defining feature of Menda's Pure-Take pump.

With conventional return-flow pumps, unused liquid in the dispensing well may drain back into the bottle.

The Pure-Take mechanism prevents this reverse flow.

This helps reduce the possibility of contaminants being carried back into the remaining liquid after contact with cleaning swabs, pads, or wipes.

The non-return design is especially useful for laboratory applications, precision cleaning, and other processes where liquid cleanliness is important.

The purity protector does not make the dispenser sterile or eliminate the need for proper handling and cleaning procedures.

Locking Design for Storage and Transport

The Pure-Take pump is designed to lock when not in use.

This helps prevent accidental dispensing and leakage during storage or movement.

The locking mechanism is particularly convenient for technicians who carry cleaning supplies between workstations or keep compatible liquids in portable service kits.

Before moving the dispenser, verify that the pump is fully locked and the bottle is securely closed.

For hazardous or flammable chemicals, follow all applicable storage and transportation requirements.

The locking feature does not replace appropriate chemical containment or safety 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-Take pump dispenses approximately 0.2 cc of liquid per press.

This small volume is convenient when only a limited amount of cleaning liquid is needed.

Controlled dispensing helps reduce unnecessary liquid consumption and avoid oversaturating cleaning applicators.

Simply press a compatible cotton swab, cleaning pad, or wipe against the pump top to obtain a working quantity.

The actual volume may vary depending on 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, contamination protection, and secure dispensing are 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 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, 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 hinged lid works alongside the Pure-Take locking mechanism to provide convenient operation and secure storage.

Silicone- and Latex-Free Pump

Menda specifies that the Pure-Take 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-Take vs. Pure-Touch vs. One-Touch

Menda offers several dispensing pump designs for different applications.

Pure-Take: Locking pump with a non-return purity protector. Designed for controlled dispensing, contamination protection, and secure storage.

Pure-Touch: Nonlocking pump with a non-return purity protector. Designed for applications where liquid cleanliness is important.

One-Touch: Nonlocking return-flow pump that allows unused liquid in the dispensing well to drain back into the bottle.

For applications requiring both non-return dispensing and a locking mechanism, Pure-Take combines these features in one pump.

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, locks securely, and prevents return flow as intended.

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.
