Description
Flocculator JLT4 is a portable laboratory instrument developed for flocculation and precipitation tests used to evaluate the effectiveness of flocculants or precipitants. It supports reproducible results across four parallel samples over a wide speed range, making it suitable for water and wastewater analysis as well as related process studies. The unit can be operated from battery power or a 12 V supply, enabling mobile use away from fixed mains connections. Technical parameters include four stirring positions, a speed range of 10–300 rpm, and a timer covering 0–999 min or 0–99 h. Background illumination aids visual observation of flock formation during the test sequence. Overall dimensions are 645×347×260 mm, with a weight of 13 kg and a power consumption of 11 W. From manufacturer LAT, the JLT4 belongs to the JLT and FC series of multi-position flocculators designed for consistent, parallel sample handling. Supplied as a single instrument, it provides laboratories with a compact, mobile platform for standardised jar-test style evaluations of coagulation and flocculation performance under controlled stirring and timing conditions.

Questions about Flokkulator JLT4
What is this article?
Flokkulator JLT4 is the article on this page. Luminix Health distributes LAT for laboratory use. It sits in Mills, grinders & homogenisers, inside Test sieves & mills, in Lab instruments.
A mill, grinder or homogeniser reduces particle size or breaks a tissue before an extraction. The rotor and the sieve insert decide the result. A knife mill and a bead mill are different machines. The sample has to tolerate the heat the motor puts into it.
A test sieve sorts particles by whether they pass an opening. Wire mesh and perforated plate are two ways of making that opening, and the nominal size is not a suggestion. A sieve shaker repeats the motion so the result does not depend on how hard someone shook by hand. A mill or grinder makes the particles smaller before they are sieved. The certificate of the sieve, and the opening size, are what an audit asks for. Measurement practice around mass and dimension sits with the BIPM, EURAMET and BELAC.
Which category should I open next?
The category is Test sieves & mills. The sub-category is Mills, grinders & homogenisers. The catalogue is Lab instruments.
