If you mean HPMC: Hydoroxypropylmethylcellulose then you need to:
1-heat 100ml of DW (deionized water) to 80-90c
2-weight HPMC grams you need to dissolve(1-5%)
3-added HPMC gradually to about 1/4 of water(25ml) while strong mixing is needed
4-then prepare 3/4 of left water with ice in it
5-then added ice water to solution while mixing and you will end in clear solution of HPMC
K means 1000 as a multiplier of 1000
K means 1000 as a multiplier of 1000
In the context of HPMC K4M, the "K" typically refers to the viscosity grade of the hydroxypropyl methylcellulose (HPMC) polymer. HPMC K4M is a specific type of HPMC with a medium to high viscosity, commonly used in pharmaceutical formulations as a thickening agent, stabilizer, or controlled-release agent. The "4M" indicates a particular molecular weight and viscosity profile, which influences its properties and applications.
In HPMC K4M, "K" refers to the viscosity grade of hydroxypropyl methylcellulose (HPMC). Specifically, HPMC K4M indicates a specific molecular weight and viscosity range that is suitable for various applications, particularly in pharmaceuticals and food products. The "4" and "M" denote the grade and the type of substitution of the cellulose ether, reflecting its properties and suitability for different formulations.
To prepare 2L of a 5M solution, you should put in 4.6575grams of KMnO4. It is important to make sure that you add them in that order. K should be added first, then Mn.
In order to prepare 50mM TES buffer, you will need to add in approximately 1000 ml of Proteinase K solution. From there, you will need to separate and stack the gels.
For the equation x2- 10x - k equals 0, you can solve this by knowing that if there is only one solution then the discriminant b2 - 4ac must be equal to 0. In this equation, a is 1, b is 10 and c is k This equation becomes 100 - 4k equals 0, and k is 25.
The solution is k = 9.
No. 100 C is the highest, then is 100 F, and 100 K is the lowest.
Heptane is a gas at 100 K.
100 K is the lowest, as it is in Kelvin scale which has the lowest absolute zero point. 100 C is equivalent to 373 K and 100 F is equivalent to 310 K, so 100 K is the lowest of the three temperatures.
100 k = 62.14 miles (to 2 dp)
