Breaking Down the Features of Grant Instruments Bath Rack 13MM Tubes J2-13

Specifications

The Grant Instruments Bath Rack 13MM Tubes J2-13 is designed with specific laboratory needs in mind. Its core specification is its capacity: it is a Test Tube Rack that holds 55 x 13 mm Tubes. This volume is significant, allowing for parallel processing of a substantial number of samples in a single incubation cycle.

The rack is constructed from materials suitable for laboratory environments, offering good chemical resistance and durability. While the exterior dimensions aren’t explicitly listed, its design is clearly optimized to fit within standard Grant Instruments water baths without excessive wasted space. The Grant Number for this specific model is J2-13, and it is supplied as a single Unit (Each).

Crucially, the temperature range it facilitates is dictated by the accompanying water bath, but the rack itself is rated for use within the typical operating parameters of such equipment, from 5° above ambient to 100°C. The temperature stability, typically around ±0.2°C, is a critical factor for many assays, and this rack ensures that tubes are consistently held within that tight tolerance. The electrical specification of 120V, 50/60Hz refers to the water bath itself, which powers the entire system, including the precise temperature control that this rack benefits from. These specifications combine to create a dependable solution for consistent sample incubation.

Performance & Functionality

In terms of its primary job – holding 13mm tubes securely in a temperature-controlled environment – this Grant Instruments rack excels. The slots are precisely sized, ensuring that tubes do not rattle around excessively during operation, which can be a problem with less well-engineered racks. This snug fit is essential for maintaining consistent thermal contact between the tube and the water bath, which directly impacts the accuracy of incubation.

The most significant strength of this rack is its high capacity for 13mm tubes. This allows for parallel processing of many samples, dramatically increasing laboratory throughput for assays requiring this specific tube size. Its primary function is straightforward, and it performs that function with a high degree of reliability. Currently, I haven’t identified any significant weaknesses in its core performance. It simply does what it’s designed to do, meeting and often exceeding expectations for a rack of this type.

Design & Ergonomics

The design of the Grant Instruments Bath Rack 13MM Tubes J2-13 is functional and focused. It eschews unnecessary aesthetic flourishes for practicality.
