General features of Laborota 20 models

Intelligent evaporation

• The automatic module Laborota 20 Distimatic with residue extraction can continually evaporate unlimited quantities in permanent operation without any restrictions as to time. Thus, it is a favourably priced alternative to the 50 and 100 liter evaporators
• Individual process control: Program ramps individually, select the programs P(cost) and T(auto), and enable the timer
• Meets highest safety standards: glassware and collection flask behind a solid PMMA shield
• Control panel with all programs for automatic distillation, vacuum controller, and display for all process parameters
• Metal and safety glass protection hood prevents any contact with the heater bath while offering full visual supervision of the reaction
• Certification according to GMP available: validation for installation (IQ) and operating qualification (OQ)
• Unique, integrated device allowing one single person to safely replace the evaporator flask alone without help
• Automatic topping up of the water bath ensures that there is always sufficient fluid in the bath
• The overtemperature protection function switches the bath off in case of uncontrolled heating. In case of overpressure or glass breakage, the entire unit will be switched off.
• A sensor measures the level of the water bath and prevents overflowing when the evaporator flask is immersed.
• A cassette system ensures that the collection flask stands safely on level surfaces

Laborota 20 safety – Highest safety and integrated vacuum control capabilities

• Excellent user safety with high impact transparent PMMA door
• Non-fogging safety glass and metal frame guard hood provides excellent user protection
• Water bath with temperatures up to 100°C and oil bath models with temperatures up to 180°C available
• Fully maneuverable optional base with removable panels for storage of vaccum pump, glassware, solvents or accessories
• Receiver cassettes and PMMA door guard against glassware breakage

Two programs for your process control

P(const): Program for solvent separations. This program holds a set vacuum constant and uses a hysteresis

T(auto): Supports very precise automatic pressure control for solvent evaporation and separations. It is able to identify multiple boiling points automatically by reducing vacuum by use of a vapor temperature. This unique program gives operator ease of use in optimizing the vacuum parameters.

Laborota 20 compact – For higher demands and integrated vacuum control

• This model features identical specifications as the LR 20 safety but for limited budget comes without these safety aspects:
  – Metal frame and safety glass guard hood covering the bath
  – High impact PMMA door covering the glassware assembly
  – High impact PMMa latching doors which cover the receiving flask cassettes
