HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

Tris HCl, also known as Trizma hydrochloride, is a widely used acidic buffer for preparing buffers within the physiological pH range of 7.3 to 7.5. With a pKa of 8.08 at 25C, Tris HCl offers a pH range of 7.0 to 9.0, matching the typical pH of living organisms. As a result, Tris HCl is an essential component of buffer solutions used in various biological, cell culture, biochemistry, and molecular biology applications. It is important to note that neither Tris base nor Tris hydrochloride on their own can provide sufficient buffering capacity. Therefore, they are typically combined to create a buffer within the pH range of 7 to 9, ensuring effective pH control.Tris buffers are indispensable in techniques like protein electrophoresis and western blotting. In many western blot protocols, a low ionic strength Tris buffer is employed for protein transfer. The transfer duration depends on the blotting apparatus and the size range of peptides under investigation. Tris-based buffers are also commonly used in SDS-PAGE gels, running buffers, and blotting buffers.Furthermore, Tris salts find extensive use in DNA agarose electrophoresis, particularly in the preparation of buffers like TAE (Tris acetate/EDTA) and TBE (Tris borate/EDTA). These buffers play a pivotal role in various applications, including biochemistry, protein purification, and electrophoresis. Tris HCl is a versatile and essential for maintaining the pH of biological systems and ensuring the optimal performance of biochemical, cell culture, and molecular biology techniques.Tris-HCl hasbenn usedas a washing and rinsing buffer in an immunohistochemical analysis(1)as a component of reducing sample buffer, lysis buffer and elution buffer, in a biochemical research involving gel electrophoresis and BioLayer interferometry measurement(2)
