Nalge Nunc Dropper Pipet, Low-Density Polyethylene, NALGENE 6219-0068 Bottle Drop 1.6ML 68MM PK100, Pack of 100 Review

Let’s Dive into Nalge Nunc Dropper Pipet, Low-Density Polyethylene, NALGENE 6219-0068 Bottle Drop 1.6ML 68MM PK100, Pack of 100

The Nalge Nunc Dropper Pipet, Low-Density Polyethylene, NALGENE 6219-0068 Bottle Drop 1.6ML 68MM PK100, Pack of 100 from Nalge Nunc, a division of Thermo Fisher Scientific, represents a straightforward and practical solution for controlled liquid dispensing. These aren’t your fancy glass pipettes found in a high-end chemistry lab; rather, they are designed for ease of use, disposability (though reusable), and applications where precision isn’t down to the microliter. The pack of 100 offers a cost-effective approach for various applications, and their construction from low-density polyethylene (LDPE) makes them resistant to many common chemicals.

My journey to finding these pipettes started when I was developing a custom waterproofing sealant for my tactical gear. I needed a reliable way to accurately measure and dispense the various components of the sealant, which included solvents, polymers, and UV protectants. I explored various options including syringes and graduated cylinders, but needed something that could withstand the harsh chemicals and offer a degree of control without requiring lab-grade precision.

Upon receiving the Nalge Nunc Dropper Pipet, Low-Density Polyethylene, NALGENE 6219-0068 Bottle Drop 1.6ML 68MM PK100, Pack of 100, my initial impression was that they were exactly as described: simple, functional, and plentiful. The LDPE material felt durable yet pliable, and the bottle-drop design of the tip seemed like it would provide decent control over the flow rate. The overall build quality appeared consistent across the batch, which is important for ensuring consistent dispensing volumes.

Compared to using a standard laboratory glass pipette, the Nalge Nunc option sacrifices a bit of precision for increased durability and ease of handling. A graduated cylinder, while accurate, is cumbersome for dispensing small volumes and can be difficult to clean, especially with viscous or fast-drying liquids. Syringes offer excellent precision, but often struggle with solvent resistance and are more expensive than these LDPE pipettes. The Nalge Nunc pipette seemed to strike a balance between these options, offering good enough accuracy, chemical resistance, and cost-effectiveness.

My first impression was cautiously optimistic. I was neither blown away nor disappointed; they seemed like a solid, utilitarian tool for the job at hand. The key test would be how they performed with the various chemicals I intended to use and whether the bottle-drop design truly provided adequate control for dispensing.

Real-World Testing: Putting Nalge Nunc Dropper Pipet, Low-Density Polyethylene, NALGENE 6219-0068 Bottle Drop 1.6ML 68MM PK100, Pack of 100 to the Test

First Use Experience

My first test involved dispensing toluene, a common solvent used in many waterproofing products. I needed to add a precise amount to a polymer base, and the Nalge Nunc pipette performed admirably. The LDPE construction showed no signs of degradation or swelling, which was a relief.

The bottle-drop tip design allowed me to control the flow rate effectively, dispensing drops with a consistent size and frequency. There was a slight learning curve to get the hang of the pressure needed for optimal dispensing, but after a few practice runs, I was able to achieve repeatable results. The relatively wide mouth made filling easy and prevented spills.

There was one minor issue: static cling. With dry air, the LDPE would sometimes accumulate a static charge, causing droplets to cling to the outside of the tip. This wasn’t a major problem, but it did require a quick wipe with a lint-free cloth to ensure accurate dispensing.

Extended Use & Reliability

After several weeks of consistent use, the Nalge Nunc pipettes have proven to be reliable and durable. I’ve used them with a variety of chemicals, including mineral spirits, acetone, and various acrylic polymers. None of these substances have caused any noticeable degradation of the LDPE.

Durability has also been impressive. While they are designed for single use, I’ve found that they can be reused multiple times, especially with careful cleaning. I typically rinse them with the appropriate solvent after each use and store them in a clean container.

Maintenance is straightforward. A quick rinse with a compatible solvent is usually sufficient to remove any residue. For more stubborn substances, a mild detergent and warm water can be used. Compared to cleaning graduated cylinders or syringes, the Nalge Nunc pipettes are significantly easier to maintain. They are also inexpensive enough that if one becomes too contaminated, it can simply be discarded without significant financial loss. They have certainly outperformed my expectations for a disposable pipette.

Breaking Down the Features of Nalge Nunc Dropper Pipet, Low-Density Polyethylene, NALGENE 6219-0068 Bottle Drop 1.6ML 68MM PK100, Pack of 100

Specifications

• Description: BOTTLE DROP 1.6ML 68MM PK100 – This tells you it’s a “bottle drop” style, has a capacity of 1.6mL, is 68mm long, and comes in a pack of 100.
• Unit: Pack of 100 – This is straightforward, confirming the quantity you receive.
• Capacity: 1.6 mL – This provides the maximum volume the pipette can hold. It’s not a precise measurement tool, but it’s useful for consistent dispensing.
• Tube Length: 68 mm – This is the overall length of the pipette, which influences how easily it can reach into containers and how comfortable it is to handle. The 68mm length strikes a good balance for most applications.
• Material: Low-Density Polyethylene (LDPE) – LDPE is crucial for chemical resistance and flexibility, offering a good balance between these properties for various solvents and solutions. It is important to note that it is not resistant to all chemicals and proper research must be done prior to use.
• Tip Design: Bottle Drop – This design provides a degree of control over the drop size and flow rate, making it suitable for applications where precision dispensing is needed.

These specifications are important because they dictate the types of substances the pipettes can handle, the volume that can be dispensed, and the overall usability of the product. The LDPE construction makes them suitable for many common chemicals, while the 1.6 mL capacity is appropriate for smaller volume applications. The bottle drop design makes it possible to deliver consistent and reliable liquid dispensing.

Performance & Functionality

The Nalge Nunc Dropper Pipet, Low-Density Polyethylene, NALGENE 6219-0068 Bottle Drop 1.6ML 68MM PK100, Pack of 100 excels at dispensing liquids in a controlled manner. The bottle drop tip allows for consistent drop sizes, which is crucial when accuracy is needed. Its simple design provides adequate control with minimal wasted material.

The strengths lie in its ease of use, chemical resistance, and cost-effectiveness. It is simple to fill, easy to dispense from, and can withstand a wide range of chemicals. The weakness lies in its lack of precise volume markings, making it less suitable for applications requiring accurate measurements. While a steady hand can approximate the volume, it’s important to note that precision is not its strong suit.

Overall, the Nalge Nunc Dropper Pipet meets expectations for a disposable pipette designed for general-purpose dispensing. It provides a good balance of performance, durability, and affordability.
