Pay attention to the following points when filtering samples through the filter 🔴Choose the right filter Material Compatibility: Choose the filter material based on the sample type. For example, PTFE filters are suitable for organic solvents, while PES filters are ideal for aqueous solutions and biological samples. Pore Size: Select an appropriate pore size (e.g., 0.22 µm, 0.45 µm) based on the required filtration level. Smaller pore sizes provide finer filtration. 🔴 Pre-wetting the filter membrane Some types of filter membranes, especially hydrophobic ones, need to be pre-wetted before use to ensure that the sample can pass through the membrane smoothly. 🔴Use of filter Slow pressure: When using a syringe or pump, apply pressure slowly to prevent the filter membrane from breaking or the sample from overflowing. Avoid air bubbles: Make sure no air bubbles enter the filter to prevent affecting the filtering effect and sample purity. 🔴 Sample processing Pre-filtration pretreatment: If there are large particles or precipitation in the sample, it is recommended to centrifuge or precipitate first to reduce the risk of filter membrane clogging. Cleanliness: Make sure all equipment used for filtration (such as syringes, bottles) are clean to avoid secondary contamination. 🔴 Storage and handling of filters Use disposable filters: Try to use disposable filters to avoid cross contamination. Proper storage: Unused filters should be stored in a dry, clean environment to avoid moisture and contamination. #aijiren #laboratory #syringefilter #Samplefilters #filtration #hplc #SyringeUsage #LabEfficiency #HighRecovery #LabAccuracy #ScientificResearch #LabSupplies #AnalyticalChemistry #InnovationInLabs Xenia Xu

Some basic information on #titrator electrodes 👇 ♦️Maintenance and care of #titration #electrodes; The maintenance and care of an electrode are decisively influenced by its type. An electrode with liquid electrolyte must also be topped up, otherwise sample solution can be pressed into the electrode if the electrolyte level is too low. In extreme cases, this can poison the electrode's reference system and render it unusable. The electrolyte depends on the type of electrode. For #pH and #redox combination electrodes, this is a KCl solution with a concentration of 3 mol/L. For #silver combination electrodes, a KNO3 solution 2 mol/L with a small addition of 0.001 mol/L KCl. For pH electrodes for non-aqueous titrations, the electrolyte solution consists of either LiCl/ethanol or LiCl/glacial acetic acid 1.5 mol/L. With a low-maintenance electrode with gel electrolyte or an electrode with pH glass as a "reference system" (AgCl 62 RG, Pt 62 RG etc.) and with measuring electrodes, refilling is not necessary. The electrolyte solutions can also always be used as a storage solution. You can also use distilled water for the RG electrodes. ♦️All electrodes with glass and metal sensor can be cleaned according to the following scheme; 👉🏼Carefully wipe off deposits on the glass membrane with a damp cloth. 👉🏼 Rinse grease/oil with alcohol or water containing detergent. 👉🏼 Remove proteins with hydrochloric acid pepsin solution L 5104. Always rinse with distilled water afterwards. Diluted hydrochloric acid (e.g. HCl 1 mol/L) can also be used as an alternative to the hydrochloric acid pepsin solution.

The third major step in the production process of gel-like emulsifiers is emulsification - Use a device such as a high-shear emulsifier, ultrasonic emulsifier, or homogenizer to fully mix the oil and water phases to create a stable gel-like emulsion. During this process, emulsifiers can help form uniform droplets. Free Sample Test Product List: https://lnkd.in/g7jBgn9r #Emulsifier #PEG #Emulsification #emulsion #uniform #waterandoil

Sywen Packaging's oral liquid filling and capping integrated machine is designed to package 10-100ML liquid or viscous liquid with unparalleled efficiency and precision. The liquid filling system utilizes advanced volumetric or overflow techniques to ensure that each bottle is filled with the desired volume. The capping mechanism applies aluminum-plastic flip-off caps with precision-controlled torque. This ensures a secure, tamper-evident seal that protects the integrity of your oral liquid products. The filling and capping processes are integrated into a single, streamlined system, which improves efficiency, and reduces product handling compared to using separate filling and capping machines. #oralliquid #syrup #pharmaceuticalliquidfilling #fillingandcappingmachine #smallvolumeliquidfilling #viscousfillingmachine
