Real-World Testing: Putting **Tegrant Thermosafe ThermoSafe Insulated Shippers, Polyurethane, Thermosafe Brands E89UPS 5.1 Cm (2″) Wall Thickness, Case of 2** to the Test
First Use Experience
My initial testing involved transporting temperature-sensitive reagents from our primary lab to a remote field calibration station. The ambient temperature during transit was a moderate 22°C, and the Tegrant Thermosafe ThermoSafe Insulated Shippers, Polyurethane, Thermosafe Brands E89UPS 5.1 Cm (2″) Wall Thickness, Case of 2 performed admirably. I placed a calibrated temperature data logger inside with the samples, and it maintained the target range for the entire four-hour journey. The polyurethane foam insulation provided a significant barrier against the exterior temperature fluctuations.
Ease of use was straightforward; the flexible polyurethane foam plug for the top made sealing the shipper a quick, secure process. There were no immediate issues or surprises, just a satisfying confirmation that the contents were protected. The robust construction made me feel confident even when placing them in the back of a utility vehicle that experiences some vibration.
Extended Use & Reliability
Over the past six months, these insulated shippers have become a regular fixture in my workflow. I’ve used them for transporting biological samples requiring refrigeration, and for short-term storage of delicate laboratory equipment that needs to avoid temperature extremes in the workshop. Despite being handled frequently, being loaded and unloaded, and occasionally stacked, they show minimal signs of wear and tear.
The closed-cell polyurethane foam insulation remains consistently effective, and the corrugate walls have held up exceptionally well. I haven’t experienced any cracking, stiffness, or compromise in their insulating properties. Cleaning is as simple as wiping down the interior if any minor spills occur, and the exterior corrugate is durable enough for regular handling. Compared to previous, less robust insulated boxes I’ve used, these ThermoSafe units are a significant upgrade in longevity and consistent performance.
Breaking Down the Features of **Tegrant Thermosafe ThermoSafe Insulated Shippers, Polyurethane, Thermosafe Brands E89UPS 5.1 Cm (2″) Wall Thickness, Case of 2**
Specifications
The Tegrant Thermosafe ThermoSafe Insulated Shippers, Polyurethane, Thermosafe Brands E89UPS 5.1 Cm (2″) Wall Thickness, Case of 2 are designed for serious temperature control needs. Each unit features a substantial 5.1 cm (2″) wall thickness of high-performance polyurethane foam. This robust insulation is key to its long-range protection capabilities for frozen or refrigerated products.
The inner and outer walls are constructed from durable corrugate, laminated to the foam core through a proprietary process. This construction results in a shipper that can withstand significant crush compression in excess of 2268kg (5000lbs.), making it suitable for demanding logistical environments. The flexible polyurethane foam plug at the top not only seals contents effectively but also allows for essential dry ice venting, a critical feature for maintaining sub-zero temperatures.
The Interior Dimensions are approximately 41.3 x 23.5 x 26 cm (16.25 x 9.25 x 10.25 inches), offering a generous volume for various items. Correspondingly, the Exterior Dimensions measure 53.3 x 35.6 x 44.5 cm (21 x 14 x 17.5 inches). These dimensions provide a balance between usable internal space and manageable external size.
The ThermoSafe part number is E89UPS, and these units are supplied in a Case of 2. The fact that they are CFC- and HCFC-free is a positive environmental consideration. The substantial wall thickness and durable build are paramount for maintaining temperature integrity over extended periods and under varying external conditions.
Performance & Functionality
In terms of its primary function – maintaining temperature – these ThermoSafe shippers excel. Whether I’m trying to keep samples cool for a day trip or preserve sensitive materials during a brief power outage in the lab, they consistently deliver. The 5.1 cm (2″) wall thickness of polyurethane foam acts as a formidable barrier against thermal transfer, significantly extending the duration for which contents remain within their desired temperature range.
The system’s biggest strength lies in its uncompromising insulation performance. I’ve had experiences where other, thinner-walled shippers would start to show temperature drift after just a few hours in moderate heat; these Tegrant Thermosafe units keep going much longer. A minor point for improvement could be the labeling space on the outer corrugate, which is somewhat limited for detailed shipping information and hazard warnings. However, this is a small trade-off for the exceptional thermal protection offered.
Design & Ergonomics
The design of these insulated shippers is highly practical and purpose-driven. The one-piece construction of the shipper itself, combined with the separate, flexible foam plug, simplifies the packing process. The polyurethane foam insulation is visibly dense and uniformly applied, suggesting excellent manufacturing quality.
The outer corrugate provides a stable, flat surface for handling and labeling, while the interior is smooth and easy to wipe down. The overall build quality feels robust; they are designed to be reusable and withstand the rigors of shipping and handling. There’s no complex assembly or delicate parts to worry about.
Durability & Maintenance
These ThermoSafe shippers are built for resilience. The polyurethane foam insulation is a closed-cell type, which means it’s resistant to moisture absorption, a critical factor for long-term durability and consistent thermal performance. The laminated corrugate exterior is surprisingly tough and resists punctures and tears better than standard cardboard.
I’ve found them to be very easy to maintain. After use, a quick wipe-down of the interior is usually sufficient. I’ve stacked them, moved them around the workshop, and even subjected one to an accidental drop onto a concrete floor (it survived with only minor scuffing, no damage to insulation). For a product designed for transport, their durability is a significant advantage, ensuring a long service life.
Accessories and Customization Options
The Tegrant Thermosafe ThermoSafe Insulated Shippers, Polyurethane, Thermosafe Brands E89UPS 5.1 Cm (2″) Wall Thickness, Case of 2 come with a very specific, yet essential, accessory: the flexible polyurethane foam plug. This plug is not merely a lid; it’s an integral part of the sealing and insulation system, providing a snug fit that minimizes air exchange.
While there are no other explicit accessories included, the shipper’s design is optimized for use with common temperature control agents like gel packs or dry ice, thanks to the built-in venting feature for the latter. The robust outer corrugate offers ample space for standard shipping labels, tracking stickers, and necessary documentation.
