Storage time of heparin lithium test tube blood collection
Negotiable
Category: Health & Medical/Pharmaceuticals & Raw Materials/Chemical APIs
Company: Hubei new DE sheng material science and technology co., LTD.
Product Description: With the development of technology, the application of biochemical testing technology in clinical practice is extremely common, providing strong support for clinical medical diagnosis. In routine blood testing, in order to improve detection efficiency or ensure accuracy, additives are often needed for auxiliary experiments. For example, the application of serum separation gel can quickly separate, or heparin lithium can play an anticoagulant role, blocking blood coagulation and prolonging blood sample coagulation time. Is it possible to use heparin lithium anticoagulant so that medical staff can conduct the experiment immediately after blood collection? Do you need to leave it for a period of time? Below is a specific introduction for everyone. Due to the fact that heparin can control thrombin from the source, causing thrombin to lose activity and preventing platelet aggregation, it can to some extent hinder blood clotting. It is precisely because of this performance that the vast majority of blood collection experiments will use it, but there are also some issues to pay attention to when using it: 1. Lithium heparin contains almost no foreign ions, so it is not commonly used to detect lithium in the blood. 2. The vacuum test tube contains lithium heparin, which needs to be placed for a certain period of time after collecting the blood sample. The main purpose is to make the blood sample fully contact with lithium heparin and have an anticoagulant effect. During the placement process, the operator is required to slowly invert and mix 5-8 times. 3. The placement time after blood collection should be within 6 hours, and it is best to complete the test within this time, otherwise it may lead to errors in the test results. 4. The placement time after blood collection should pay attention to the interference of environmental temperature, especially when the blood collection environment conditions are above 25 degrees, the placement time should be shortened as much as possible, otherwise local coagulation will affect the detection process. 5. Pay attention to the amount of lithium heparin added, and ensure that the blood sample is fully anticoagulated to ensure that the blood does not change within 6 hours. 6. Heparin lithium can usually be used in combination with serum separation gel. Within a certain period of time, it is not only necessary to pay attention to the anticoagulant effect of heparin lithium, but also to the separation effect of serum separation gel. After complete separation and standing for a period of time, it can be tested and analyzed on the machine. From the above six aspects, it can be seen that the heparin lithium tube needs to be left for a period of time after blood collection, but it should not exceed 24 hours, and the test should be completed as soon as possible. As a professional manufacturer of heparin lithium, Desheng not only has rich experience, but also pays close attention to quality. All key indicators of its products must meet the standards before they can be sold before leaving the factory. If you have any more>

Two Characteristics of Biological Buffer TRIS (77-86-1)
Negotiable
Category: Chemicals/Chemical Intermediates/Intermediate Compounds
Company: Hubei new DE sheng material science and technology co., LTD.
Product Description: TRIS is a commonly used biological buffer in laboratories and manufacturing industries. Its function is to regulate the required pH value, stabilize product quality, and neutralize agents. This ingredient is present in daily life, from cosmetics we often use to household appliances (air purifiers). So what kind of substance is TRIS? This article will provide an introduction. For the convenience of the public's usage needs, TRIS usually exists on the market in two forms: powder form and solution form. There is no other difference between the two except for their different traits. 1. TRIS powder For general customers, if there is a large demand for TRIS usage, they usually purchase TRIS powder. Because powder is more convenient to transport than solution, there are no high requirements for storage conditions. Simply seal and avoid light and moisture. In addition, the configuration method is relatively simple, and it can be configured and used immediately to avoid waste. 1. TRIS solution TRIS solution is a buffer solution that can be directly used as a finished product, without the need to configure it yourself. It can be purchased and used. Suitable for small amounts of use and purchases by individuals who do not know how to configure in experiments. It is worth noting that the prepared TRIS solution has high requirements for storage environment and needs to be sealed and stored in an environment below -4 ℃, otherwise it will cause the solution to deteriorate and affect the experimental results. The above is an introduction to the two different properties of TRIS buffer, which can be selected based on one's own experimental and production needs. However, the editor believes that whether TRIS is good or not depends on whether it is powder or solution. Instead, we choose manufacturers with reliable quality, stable product performance, and purity standards for cooperation, in order to ensure the infallibility of the experiment. Desheng is a manufacturer of TRIS powder, and its buffer products are mainly sold in powder form. There are currently over thirty types of buffering agents on sale. The batch is stable, the quality is reliable, and the purity can reach over 99%, which can meet the usage needs of different industries. Products ranging from kilograms to tons can be provided, produced and sold by oneself, with high daily production capacity, which can meet the demand for bulk goods. If you need to make a purchase, please feel free to call us for consultation and ordering at any time! more>

4 pH buffers of Desheng used in cosmetics
Negotiable
Category: Chemicals/Chemical Intermediates/Intermediate Compounds
Company: Hubei new DE sheng material science and technology co., LTD.
Product Description: Every biological system has a well-known buffer system to maintain the acid-base balance within a specific pH range. Our lives depend on the function of the buffer system. A buffer system is a solution that resists changes in pH when acid or alkali is added. Different buffers have different ability and efficacy for skin replacement. The high-quality Good's Buffers produced by Desheng are usually used in cosmetics, such as toners, essences, lotions, eye creams and facial masks, etc., according to your application. Here are 4 biological buffers commonly used in cosmetics. 1) HEPES (4-hydroxyethylpiperazine ethanesulfonic acid) CAS Number: 7365-45-9 Useful pH range: 6.8-8.2 The main purpose 1. Acidity regulator, or pH control agent. 2. An effective concentration of HEPES can provide an exfoliating effect. 3. Promote the transdermal absorption of various functional ingredients in cosmetics. 2) TRIS (Tris(hydroxymethylaminomethane)) CAS number: 77-86-1 Useful pH range: 7.2-9.0 use: 1. Non-ionic surfactants-amines 2. Acidity regulator or pH control agent. 3. Excellent cleaning ability and emulsifying ability. 3) BIS-TRIS (Trimethylol) Methylamino Propane) CAS Number: 5625-37-6 Useful pH range: 6.1-7.5 The main purpose 1. Non-ionic surfactants-amines 2. Acidity regulator, or pH control agent. 3. Excellent decontamination, dispersion, emulsification and antistatic ability. 4) Glycylglycine buffer (G-132) CAS Number: 7365-44-8 Useful pH range: 7.5-8.9 The main purpose: 1.
