About Alcotabs®

Alcotabs consists primarily of a homogeneous blend of sodium linear alkylaryl sulfonate, phosphates, carbonate and excipient ingredients added to aid in tabletting. Alcotabs are anionic in nature.

Why Alcotabs®

Alcotabs are critical-cleaning detergent tablets that are versatile in that they

  • Are special slow-release tablets with a formulation for maximum cleaning performance from your syphon pipette washers
  • Are concentrated to save you money
  • Are biodegradable and disposable
  • Are free-rinsing to give you quality results
  • Are used to pass your cleaning and inspection approvals

Alcotabs is used to clean

  • Pipettes and tubes with syphon pipette washers in hospital, clinical, educational, R&D and industrial laboratories and cosmetics manufacturing

Alcotabs is used to remove

  • Soil
  • Grit
  • Grime
  • Grease
  • Fats
  • Oils
  • Blood
  • Tissue
  • Salt deposits
  • Particulates
  • Chemicals
  • Solvents
  • Radioisotopes

Alcotabs is used to clean surfaces, such as

  • Glass
  • Metal
  • Stainless steel
  • Porcelain
  • Ceramic
  • Plastic
  • Rubber
  • Fiberglass
  • Aluminum
  • Zinc
  • Magnesium

Directions

  1. Submerge pipettes immediately after use in a 1% Alconox, Liquinox, or Tergazyme solution.
  2. Let soak in jar until enough pipettes accumulate to fill holder.
  3. Drop 2 Alcotabs into the rinser.
  4. Place the holder with pipettes into rinser.
  5. Alcotab will dissolve (in cold or warm water) and effervesce, producing a detergent solution that passes up and down through the bores and around the pipettes.
  6. Rinsing automatically follows after the tablet has dissolved.
  7. For analytical or tissue culture work, use distilled, deionized, or purified water for all or final rinse.

Cleaning Validation Methods

Test a parameter of rinse water before and after rinsing the cleaned surface, or test the clean surface. No significant change in the parameter indicates no detectable residue. Parameters measured include: conductivity, UV, TOC, HPLC, sodium concentration, phosphorus concentration, anionic surfactant concentration using inexpensive detergent water testing kits, surface tension, and surface analysis.
