Sub-boiling Acid Stills

The increasingly lower limits of detection available with ICP and ICP-MS require ultra pure matrices. SPEX CertiPrep® sub-boliing acid stills allow you to prepare ultra pure acids right in your laboratory at a fraction of the cost of purchasing these regents. The distillation method of surface evaporation without boiling is employed through the use of infrared heaters. Most metals can be reduced below parts per billion in a single distillation.

The PTFE sub-boiling acid still handles all common acids except sulfuric and can produce up to 50ml per hour of operation. Liquids and vapors come in contact with PTFE and PFA Teflon only to produce ultra pure acids.

Uses standard 250W IR lamp. 27W x 27D x 60H (cm), 16kg, 11Vac, 250W

The quartz sub-boiling acid still has two radiant IR heaters. It handles all common acids except HF and can produce up to 200 ml per hour of operation. Liquids and vapors come in contact with Quartz only. 65W x 25D x 55H (cm), 20kg, 220Vac, 1200W, Acid Stills
