For procurement managers and R&D scientists in the pharmaceutical and chemical industries, sourcing high-quality Lithium Heparin powder is a critical task. This anticoagulant is a vital component in blood collection tubes, ensuring the accuracy of biochemical and hemorheology testing. This guide aims to equip buyers with the knowledge to make informed purchasing decisions, focusing on the specifications, applications, and the importance of partnering with reliable manufacturers and suppliers.

Lithium Heparin, identified by CAS No: 9045-22-1, is prized for its ability to prevent blood clotting by enhancing the action of antithrombin. This makes it indispensable for collecting plasma samples without the interference that could skew results in ion determination and other biochemical assays. Its physical form as a white, amorphous, odorless powder that is soluble in water and hygroscopic dictates specific storage and handling protocols. However, its minimal interference with common analytes makes it a preferred choice for many diagnostic tests.

When evaluating Lithium Heparin for purchase, several key specifications must be considered: purity (ideally above 99%), potency (commonly stated as greater than 150 IU/mg), and average molecular weight. These parameters directly influence the anticoagulant's effectiveness and its compatibility with various diagnostic platforms, including automated systems used in high-throughput laboratories. Buyers looking to 'buy Lithium Heparin' should inquire about these technical details from potential suppliers.

The primary application for Lithium Heparin powder is as an additive in blood collection tubes. These tubes are used for a wide spectrum of tests, including routine clinical biochemical examinations, emergency biochemical tests, and specific hemorheology studies. Its role in preserving the integrity of plasma samples without significantly affecting electrolyte balance is a major selling point. Therefore, securing a consistent supply of this reagent from a trusted manufacturer is essential for uninterrupted laboratory operations.

For those seeking to purchase Lithium Heparin, particularly in bulk quantities, identifying a reliable manufacturer and supplier is paramount. Companies often look for suppliers in China due to competitive pricing and established manufacturing capabilities. It is advisable to request samples and Certificates of Analysis (CoA) to verify the product's specifications and quality. Understanding the supplier's manufacturing capacity and their commitment to quality control processes will ensure a stable and dependable source for this critical laboratory reagent. Engaging with suppliers who can provide competitive pricing for bulk orders is also a key procurement strategy.
