Yacht sinks are sinks that sit on top of a counter-top rather than being lowered into or mounted under that. Most often the vessel can be described as round bowl shaped vessel but the basin can be any kind of size or shape. Besides bowls, square basins happen to be popular. Vessel sinks could be made out of a variety of materials however the most popular are wineglass, stone, or metal. The vessel can sit upon the counter or over a base which builds up more. If you have this kind of sink you need to think carefully about the sinks that you use. They need to be capable of geting the water up and over the vessel edge and the controls need to be easily accessible. Vessel basins are trendy and are frequently seen in homes that offer modern design and decorating. You can use a vessel sink in any bathroom that has deal with space.

Inianwarhadi - Dissolution analyses: comparison of profiles using f2. The model developed by moore and flanner is used to compare the dissolution profile using two factors, f1 and f2 1 following the fda guidance for comparing the dissolution profiles 2, 3 a profile comparison is not necessary for products that are rapidly dissolving i e , more than 85% in 15 minutes or less. Dissolution f1 and f2 analysis and ivivc slideshare. Dissolution f1 and f2 analysis and ivivc 1 comparison of dissolution profile by different methods & ivivc presented by sh gujarathi m pharm 1st sem dept of pharmaceutics 1 poona college of pharmacy, centre of advanced research in pharmaceutical sciences guided by dr mrs v b pokharkar, vice principal and head of department of pharmaceutics. Dissoultion profile comparison dissolution tech. Among several methods investigated for dissolution profile comparison, f2 is the simplest moore and flanner proposed a model independent mathematical approach to compare the dissolution profile using two factors, f1 and f2 1. Dissolution similarity requirements: how similar or. Dissolution profiles may be considered similar by virtue of overall profile similarity and similarity at every dissolution sample time point the dissolution profile comparison can be conducted using model independent or model dependent statistical methods. Evaluation and comparison of in vitro dissolution profiles. The obtained dissolution profile data of the eight brands were evaluated and compared with the innovator brand amoxil TM using two different statistical methods: the fit factors f1 & f2 and the dissolution efficiency d e model most generic brands of amoxicillin capsules 62 5% of the tested brands are not interchangeable with the. Leveraging dissolution testing to meet regulatory guidelines. Dissolution testing is a standard tool in a formulation scientist's arsenal when companies make changes to drug products particle size, excipients, manufacturing process, equipment, etc , health authorities often require comparing dissolution profiles to determine if the reference and test products are equivalent. F1 & f2 dissolution. Hello all: this topic has been discussed countless times, but i'm still not 100% clear could you guys verify my thinking: 1 what is the difference between f1 & f2? f1 compares the results at the same time points, whereas f2 compares the overall profiles is this the main difference? is this why industry generally prefers f2?. F1 and f2 test dissolution discussion group ddg. F1 and f2 test the dissolution rate was initially so fast that there was no curve, just a spike and decay after some development this rate has been slowed to have tmax at ~5 minutes, with a nice looking bell shaped profile. F2 similarity factor dissolution testing. An f2 parameter is commonly used to establish similarity of two dissolution profiles the formula and procedure to obtain f2 value is described in one of the publications in short, two profiles are considered identical when f2=100 an average difference of 10% at all measured time points results in a f2 value of 50.
