1. The kit should be taken out of the refrigerated environment and equilibrated at room temperature for 15-30 minutes before use. If the enzyme-coated plate is unsealed after opening, the strip should be stored in a sealed bag. 2. Crystals may be precipitated in the concentrated washing liquid, which can be heated and dissolved in a water bath during dilution, and the results will not be affected during washing. 3. The sampler should be used at each step of sample addition, and the accuracy should be regularly checked to avoid test errors. It is best to control the sampling time within 5 minutes. If there are many specimens, it is recommended to use a volley gun to add samples. 4. Please make a standard curve at the same time of each measurement, it is best to make a double hole. If the content of the substance to be tested in the specimen is too high (the OD value of the sample is greater than the OD value of the first well of the standard well), please dilute it with a certain multiple (n times) of the sample diluent and then determine it. Please multiply the total dilution for the calculation Multiple (× n × 5). 5. The sealing film is limited to one-time use to avoid cross-contamination.

SIZE MATTERS - BE THE ENVY OF YOUR BUDDYS - Don`t be judged by the length of your handle, there's no need to get too close to that roaring fire as you turn and handle your cuts of meat and veg like a pro! 
NO MORE BURNT ARM HAIR -  The quality design allows for easy handling at safe distances from the flame. The varying size gives your tong set the versatility all great grill masters look for in their tools!
SAVE YOUR MONEY AND YOUR MEAT - Buy 2 lengths of tong you`re gonna use, rather than 1 you`re not. It's easy to purchase the first thing that looks ok, but, he or she who buys cheap buys twice! The quality is apparent and the ease of use a BBQ geeks dream!

LOOK THE PART AND KEEP THE TONGS - It's important to know what your doing come meal time and the first rule of barbecue is to not cross contaminate by turning your chicken and then your steak for example - Protect your reputation when cooking up a storm and throwing awesome backyard parties. You're the King now!
