Breaking Down the Features of Nalge Nunc Graduates, Double Scale Pharmaceutical, NALGENE 3673-0016

Specifications

The Nalge Nunc Graduates, Double Scale Pharmaceutical, NALGENE 3673-0016 is precisely engineered for laboratory precision. Its capacity is listed as 16 oz., which conveniently translates to 500 mL, offering a versatile volume range for many applications. The NNI No. 3673-0016 identifies this specific model within the Nalge Nunc catalog.

The material itself, polymethylpentene, is a critical specification contributing to its performance. This polymer offers remarkable transparency, shatterproof qualities, and excellent chemical resistance. It also boasts impressive heat tolerance to +175°C, allowing for use in a wider range of temperature conditions than many conventional plastics.

The dual-scale graduation in ounces and milliliters is a key feature, providing flexibility for users accustomed to either system. For the 125, 250, 500, and 1000 mL sizes, the graduate conforms to the volume and accuracy requirements of ASTM E1094, a standard that underscores its metrological integrity. Furthermore, the octagonal base provides superior stability, preventing accidental tipping, a common issue with cylindrical bases. It’s important to note that autoclaving may alter accuracy, a crucial detail for maintaining precise measurements over time. The smallest sizes feature a clear base, while larger ones, like the 3673-0016, utilize a black base for enhanced readability of the fluid meniscus against the scale.

Performance & Functionality

In terms of performance, the Nalge Nunc Graduates, Double Scale Pharmaceutical, NALGENE 3673-0016 excels at its primary function: accurate volume measurement. The clarity of the markings, combined with the material’s optical properties, ensures that reading the precise volume is straightforward and reliable. The double scale is brilliantly implemented, with both ounces and milliliters clearly delineated, minimizing the need for conversions during critical procedures.

Its primary strength lies in its durability and safety; the shatterproof polymethylpentene construction offers a significant advantage over glass, reducing the risk of accidents and contamination. The excellent chemical resistance means it can be used with a broad spectrum of laboratory chemicals without degradation. However, a potential weakness, albeit minor and acknowledged by the manufacturer, is that autoclaving may alter accuracy. This means users needing absolute precision after autoclaving should consider recalibration or alternative sterilization methods. Despite this caveat, its overall functionality and reliability are exceptional for most pharmaceutical and laboratory applications.

Design & Ergonomics

The design of the Nalge Nunc Graduates, Double Scale Pharmaceutical, NALGENE 3673-0016 prioritizes both utility and user experience. The use of polymethylpentene provides a satisfying balance of rigidity and lightness, making it comfortable to hold and pour from for extended periods. The octagonal base is a standout ergonomic feature, offering a stable foundation that inspires confidence.

Its transparency is second to none, allowing for easy observation of the fluid level and any potential inclusions. The clear, black base on this 500 mL model further enhances readability, particularly with lighter colored liquids, by providing a stark contrast for the meniscus. There is virtually no learning curve; its intuitive design means anyone familiar with graduated cylinders can pick it up and use it effectively immediately.

Durability & Maintenance

The durability of the Nalge Nunc Graduates, Double Scale Pharmaceutical, NALGENE 3673-0016 is a significant selling point. Constructed from shatterproof polymethylpentene, it is far more resilient to accidental drops and impacts than traditional glass. This inherent toughness translates to a longer service life and reduced replacement costs.

Maintenance is straightforward. The graduate is easy to clean with standard laboratory detergents and can withstand high temperatures, although the manufacturer advises that autoclaving may alter accuracy. Its resistance to a wide array of chemicals means it can be thoroughly cleaned and sterilized without concerns of material degradation. The smooth surface also resists the adherence of residues, further simplifying the cleaning process.

Accessories and Customization Options

As a standalone laboratory instrument, the Nalge Nunc Graduates, Double Scale Pharmaceutical, NALGENE 3673-0016 does not typically come with a wide array of accessories or extensive customization options in the traditional sense. Its value lies in its inherent design and material properties. However, the product description does mention that the 30 ml size is also graduated in drams, indicating variations within the product line that might cater to niche measurement needs.

The true “customization” for this graduate comes from its selection within the broader Nalge Nunc range, offering different sizes and potentially specialized markings depending on the specific catalog number. For instance, the black base featured on this 500 mL model (NNI No. 3673-0016) is a design choice intended to improve usability, which could be considered a form of functional customization for better visibility. Compatibility with other brands is generally not a factor for graduated cylinders, as they are primarily standalone measuring devices.

Pros and Cons of Nalge Nunc Graduates, Double Scale Pharmaceutical, NALGENE 3673-0016
