First, choline
Choline cannot be used with certain vitamins and calcium or phosphorus. Because choline is very alkaline, it is easily soluble in water, which can damage water-soluble vitamins and pantothenic acid. Phosphorus and calcium are easily absorbed in an acidic environment and little in an alkaline environment. Therefore, choline cannot be used simultaneously with bone powder, calcium hydrogen phosphate, and the like.
Second, vitamin B1
Because the water solubility of vitamin B1 is strongly acidic, it will have a destructive effect on penicillin. Therefore, vitamin B1 cannot be used simultaneously with penicillin.
Third, ferrous sulfate, iron hydroxide
Ferrous sulfate and iron hydroxide can not be used together with vitamin A, vitamin D, vitamin E, vitamin B1 and vitamin B2. If used at the same time, ferrous sulfate and iron hydroxide additives will accelerate vitamin A, vitamin D, vitamin E and vitamins. B1, oxidative destruction process of vitamin B2 additive.
Fourth, calcium carbonate
Calcium carbonate cannot be used simultaneously with vitamin B1, vitamin B2, vitamin C, vitamin K1, vitamin K2, pantothenic acid, penicillin, oxytetracycline and the like. Because calcium carbonate is alkaline, vitamin B1, vitamin B2, vitamin C, vitamin K1, vitamin K2, pantothenic acid, penicillin, oxytetracycline and the like are easily destroyed in an alkaline environment.
Five, oxytetracycline
Oxytetracycline cannot be used simultaneously with penicillin, streptomycin, and the like. Because the acidity of oxytetracycline is very strong, it can destroy the anti-disease effect of penicillin and streptomycin.
This micropipette enables true one-handed operation without changing the holding position: adjust volume, Pipette, remove tip.
Regardless of the volume, you can use your pipettes for ergonomic and efficient operation. The operation force is small and the stroke is short, which can easily handle long-term continuous pipetting operations. It is designed with perfect ergonomics for a comfortable grip in any hand position, right or left, large or small.
Even when wearing gloves, the range lock can be easily operated to lock the set range and prevent accidental adjustment errors. For a quick calibration experience, easy-to-calibrate technology makes calibration a snap. Calibration can be done without auxiliary tools. Compatibility tables describe how tips fit into pipettes, making it easy to find the right tip.
