â‘ Before use, you must check for needle burrs, needle curls, and simple body cracks.
â‘¡In order to eliminate the residue of the previous sample between samples, the samples need to be washed 5 to 20 times. However, the first 2 to 3 samples must be discarded.
â‘¢ In order to remove air bubbles from the syringe, immerse the needle tip in the sample solution and repeat the extraction and pushing operation. (It is easy to remove air bubbles by moving the needle up.)
â‘£Sample more samples than required, and then align with the scale. Be careful not to tilt the syringe. Wipe the tip of the needle with paper that does not produce fine fibers before injecting.
⑤ After use, it must be cleaned with pure water or acetone, and stored after air drying.
ã€Sample cleaning method】
For the solvent used to clean the syringe, the solubility of the residual substance (used sample, etc.) must be considered, and pure water, methanol, acetone, etc. are usually used.
â—† Whole cleaning of the injection needle
â‘ Wash with warm water and non-alkaline, phosphorus-free detergent
â‘¡ Use pure water or acetone to extract and push out, and perform short-time cleaning.
â‘¢ Dry with air.
â—† Core rod cleaning
â‘ After cleaning, wipe the mandrel with a clean cloth, etc., and then put it back into the syringe.
â‘¡ When inserting the syringe, please pay attention to whether the core rod is bent.
â—† Cleaning of injection needle
â‘ When cleaning the needle, be careful not to block the needle eye.
â‘¡The syringe is filled with cleaning solvent, and push the core rod firmly.
③Be careful not to curl the tip of a needle with a sharp tip (PT-2 · PT-4, etc.). In case the needle tip curls, use a needle grinder to grind.
[Notes on the use of syringes]
â‘ Do not immerse the syringe in the solvent. Will cause cracking of the bonded part.
â‘¡ Do not place the syringe in an environment with rapid temperature changes. Will cause damage.
â‘¢ Do not leave the syringe in strong acid or polar solvent for a long time. Will cause cracking and damage.
â‘£ Epoxy adhesive is used for the connection between the needle and barrel of the fixed needle injection needle. Therefore, the adhesive may flow out due to the erosion of the used sample or cleaning solvent. Please select the appropriate syringe according to the sample used.
[Notes on the use of mandrel]
â‘ Since the core rod (metal core rod) of the micro-injection needle is matched with each syringe for inspection, the core rod cannot be exchanged.
â‘¡ Do not push or pull the core rod when the inside of the syringe is dry (in the state where the sample is not drawn), otherwise the inside of the syringe may be damaged.
â‘¢The bent mandrel will negatively affect the use of the syringe, so please pay attention to whether the mandrel is bent.
â‘£ Do not push or pull the core rod when the needle is clogged. Due to the high pressure, cracks may occur on the barrel.ZENGHUI PAPER PACKAGE is a good Apparel Packaging manufacturers and suppliers with good reputation, we have our own Shoe Box factory, we are able to provide our customers varieties of shoe boxes with good quality and reasonable price. such as corrugated shoe boxes,rigid shoe boxes,folding shoe boxes etc.Welcome to wholesale products from us.
