Laboratory & Industrial Testing Application Solutions

Stirring and heating setup for laboratory mixing and temperature control. Pair an overhead stirrer with an oil bath, water bath or heating mantle to dissolve solids, disperse powders into liquids and hold reactions at a set temperature.

Selection guide: heated or room-temperature, 1 to 6 positions, per-position capacity and the right PTFE stir bar for your vessel type.

Step-by-step rotary evaporation setup guide. Pair an oil-free diaphragm vacuum pump with a digital water bath and heating mantle, connect dual-neck filter flasks, and run safe solvent recovery at the recommended vacuum and bath temperature.

Particle size analysis by laboratory sieve method. Build a test sieve stack from coarse to fine mesh over a collection pan, dry and weigh each fraction, then calculate the particle size distribution of powders and granular materials.

Selection guide: pick the frame diameter from 6 to 40 cm, read aperture from two size charts covering 8.00 mm down to 3 µm, and confirm your standard — ASTM E11, ISO 3310-1 or GB/T 6003.1.

Water baths, oil baths and heating mantles in one guide: settle the temperature boundary first, then size the tank, match the openings and decide when PID control is worth paying for.

A 21-grade mesh-to-micron aperture chart for 3–140 mesh, with the ASTM E11 sieve of the same number alongside — 12 of the 21 grades cannot be matched to ASTM E11 by number. Free 2-page printable PDF.
