In the laboratory field, weighing precision plays a central role in the reliability of analyses, whether for scientific research, quality control, or industrial development. The choice of scale used cannot therefore be taken lightly. Yet, purchasing new equipment is not always compatible with an institution's budgetary constraints, especially when it comes to equipping several workstations or upgrading an aging fleet.
Opting for a used laboratory scale, when it is carefully refurbished, tested, and guaranteed, constitutes a high-performance and sustainable solution. This is precisely the approach championed by Rewake, which offers a rigorous selection of weighing instruments adapted to the technical and regulatory requirements of professionals. This article provides a complete overview of the criteria to consider, the existing models, and the best practices for choosing your refurbished laboratory scale.
Why choose a used laboratory scale?
In a context where cost control has become a strategic issue for laboratories, the purchase of refurbished equipment stands out as a relevant alternative to new equipment. A used laboratory scale provides access to professional instruments designed for intensive use, while significantly reducing the initial investment. This approach is particularly suitable for chemistry, biology, food processing, or quality control laboratories, which require consistent performance without compromising on precision.
When rigorously refurbished, a used scale offers guarantees comparable to those of new equipment. Models from major brands recognized for their reliability benefit from robust design, excellent weighing stability, and long-lasting precision. Turning to a used laboratory scale thus makes it possible to reconcile metrological requirements, regulatory compliance, and budget optimization, while engaging in a responsible approach to extending the lifespan of equipment.
The different types of laboratory scales available second-hand
The second-hand market covers a wide variety of laboratory scales, allowing for different uses depending on activities and requirement levels. Analytical balances are used for high-precision weighing, often to the milligram or hundredth of a milligram, particularly in analytical chemistry, pharmaceuticals, or scientific research. They are distinguished by their high sensitivity, protected weighing environment, and advanced calibration functions.
Precision balances, which are more versatile, are commonly used for dosing operations, quality control, or sample preparation. They offer an excellent compromise between capacity, robustness, and accuracy. Other categories also exist, such as compact scales for restricted spaces or industrial scales suitable for higher loads. Opting for a refurbished laboratory scale allows you to access these different technologies, with features such as LCD displays, tare functions, counting, or dynamic weighing, while respecting the technical constraints of the laboratory.
Precision, calibration, metrology: what you need to check
In the laboratory field, weighing precision is a determining criterion. It depends not only on the manufacturing quality of the scale but also on its calibration and metrological maintenance. A used laboratory scale must have been correctly calibrated, either internally via an automatic system or externally using certified weights. It is essential to verify the presence of a calibration certificate, often issued by accredited bodies such as COFRAC.
Metrological monitoring also involves a maintenance logbook detailing periodic checks, adjustments made, and any repairs. These elements guarantee the reliability of weighing in regulated environments, particularly in chemistry, pharmaceuticals, or laboratories subject to quality audits. To ensure compliance with ISO standards or traceability requirements, it is advisable to choose scales with an automatic adjustment function, level indicator, and measurement unit management. This level of requirement helps to ensure the reliability of every weighing operation.
Which materials and finishes should you prioritize for your work environment?
The choice of materials composing a laboratory scale directly influences its durability, precision, and ability to resist the specific constraints of each environment. For laboratories handling corrosive products, a stainless steel pan is preferable. It offers excellent chemical resistance, facilitates cleaning, and extends the life of the device. Some models are also equipped with protective covers or a reinforced ABS housing to withstand splashes and impacts.
Scales designed for demanding environments (damp zones, laminar flow hoods, cleanrooms) can benefit from a high IP rating (e.g., IP65), ensuring optimal protection against dust and liquids. Options like a touchscreen, a backlit LCD display, or a USB interface facilitate integration into a modern workstation. It is also relevant to evaluate the stability of the pan, the presence of adjustable feet, and an integrated draft shield for high-precision weighing, particularly in analytical applications.
Rewake: a rigorous selection of used laboratory scales
At Rewake, each used laboratory scale undergoes a methodical refurbishment process, ensuring its technical reliability and compliance with professional requirements. Our specialized technicians carry out a series of checks: electronic control, weighing system calibration, precision testing, validation of the LCD or touchscreen stability, stainless steel pan inspection, and replacement of wear parts if necessary. Each device is cleaned, restored, and verified according to a strict protocol.
We make it a point of honor to offer scales from recognized brands (Kern, Mettler Toledo, Adam Equipment, etc.), with capacities and precisions adapted to the varied needs of laboratories. A certificate of compliance or calibration can be provided as appropriate. All our equipment is covered by a warranty, with responsive after-sales service, personalized technical advice, and the possibility of ensuring metrological monitoring. Rewake thus positions itself as a trusted partner for the sustainable equipping of laboratories.
Precision, repeatability, and the general condition of the device are among the elements to check before putting it back into service. A refurbished used laboratory scale can thus provide access to professional equipment while extending the usable life of existing hardware.
Buying a used laboratory scale: best practices
Before investing in a used laboratory scale, it is essential to precisely evaluate your needs. Define the type of weighing (analytical, precision, counting, etc.), the maximum capacity (in grams or kilos), the desired resolution (milligram, hundredth of a gram, etc.), as well as the required functions (tare function, dynamic weighing, parts counting, USB interface, etc.). Check compatibility with the instruments or software you already use in your laboratory.
Request a clear quote including technical specifications, refurbishment status, warranties, and after-sales service options. Consult the associated documents: calibration certificate, technical data sheet, and metrological logbook if available. Also, ensure that the device has been tested, cleaned, and that it respects the standards applicable in your sector (pharmaceutical, food processing, public research, etc.). By choosing a specialized dealer like Rewake, you benefit from technical advice, complete traceability, and long-term support.
Refurbished laboratory scales, reliable and ready for use
Opting for a refurbished used laboratory scale is a strategic choice for laboratories looking for precision, performance, and budget control. Whether they are ultra-sensitive analytical balances, counting models, or industrial weighing instruments, each device can meet the most stringent technical requirements, provided it is carefully selected and tested.
Through a rigorous refurbishment process, Rewake guarantees a high level of reliability, with equipment that is verified, calibrated, cleaned, and accompanied by compliance documents.
