Features: 1. Pure white appearance, good drug resistance, strong acid and alkali corrosion resistance; 2. High and low temperature resistance: can be used at -200 - 250 degrees Celsius, and can be used in high temperature heating environment if necessary; 3. Insulation: not affected by environment and frequency, small dielectric loss, high breakdown voltage; 4. Resistant to atmospheric aging, radiation and low permeability; 5. Good non-stick surface, smooth inner wall surface, easy to clean; 6. Support customization of different shapes and sizes. Using PTFE (polytetrafluoroethylene) material for deep water samplers offers several advantages over traditional glass or ordinary plastic materials: 1. Chemical Resistance: PTFE is highly resistant to a wide range of chemicals, making it ideal for sampling environments where aggressive substances may be present. This ensures that the sampler will not react with or contaminate the samples. 2. Durability: PTFE is known for its excellent mechanical strength and resilience. It can withstand high pressures and harsh conditions found in deep water environments without cracking or breaking. 3. Low Surface Energy: PTFE has a low surface energy, which reduces the adhesion of contaminants and minimizes sample loss. This property enhances the purity of the collected samples. 4. Temperature Stability: PTFE can maintain its properties over a wide temperature range, making it suitable for various thermal conditions encountered in deep water sampling. 5. Lightweight: Compared to glass, PTFE is significantly lighter, making it easier to handle and deploy in deep water settings. 6. Non-stick Surface: The non-stick nature of PTFE helps in easier cleaning and maintenance of the sampler, ensuring reliable and repeatable sampling results. 7. Longevity: PTFE samplers have a longer lifespan compared to plastic alternatives, which may degrade over time due to UV exposure or chemical interaction. These advantages make PTFE deep water samplers a superior choice for researchers and environmental scientists seeking reliable and contamination- free sampling solutions. web: https://www.njbinglab.com Phone/Whatsapp/ Wechat :+8615805176994 Mail: rossnjbzh@gmail.com / rossg@njbinglab.com

Pregabalin, also known as Lyrica, is a prescription drug used to treat nerve pain, epilepsy, and generalized anxiety disorder. It belongs to a class of drugs called anticonvulsants, which work by calming overactive nerves in the brain and reducing abnormal electrical activity. Pregabalin is commonly used to treat chronic pain such as diabetic neuropathy, fibromyalgia, and postherpetic neuralgia. Pregabalin powder is an anticonvulsant and analgesic medication from the gabapentinoids class of drugs that inhibit nerve activity in the brain, similar to GABA neurotransmitter. It has long been utilized as a means of treating epilepsy, neuropathy pain and anxiety-related conditions. Pregabalin powder is one of the most promising drugs in development for the treatment of epilepsy, with better efficacy and easier administration. It can also be used to treat pain and anxiety.

D-Lysergic Acid Methyl Ester is a chemical compound that falls under the category of lysergamides, which are a class of psychoactive substances known for their hallucinogenic effects. D-Lysergic Acid Methyl Ester, also known as LAMPA, is a synthetic compound derived from lysergic acid, a naturally occurring compound found in certain fungi and seeds. It is a psychoactive substance that is commonly used for research purposes and has a chemical structure similar to other lysergic acid derivatives, such as LSD. This compound is closely related to LSD (Lysergic Acid Diethylamide), a well-known psychedelic drug.  One of the key features of D-Lysergic Acid Methyl Ester is its ability to interact with serotonin receptors in the brain. Serotonin is a neurotransmitter that plays a key role in regulating mood and cognition, and many psychoactive substances, including LSD, work by modulating serotonin activity. D-Lysergic Acid Methyl Ester binds to serotonin receptors in a similar manner to LSD, which may explain its hallucinogenic effects.
