What are the core differences between LRE-2L-Pro and manual LRE-2L-S?
7 key distinctions: ①Lifting: Pro 150mm full motorized lift with auto power-off anti-boil-dry safeguard; S purely manual lift without power failure protection. ②Max speed: Pro 280rpm vs 200rpm of S. ③Heating power: Pro 1300W, S 1200W. ④Condenser: 1700cm² large condenser standard for Pro, optional upgrade for S. ⑤Display: Large LCD screen for Pro, basic simple LED screen for S. ⑥Unit weight: Pro net weight 15kg, S main unit only 7kg. ⑦Automation: Pro built-in USB data export function for full traceability, S without complete data logging.
Will the evaporating flask lift automatically after sudden power cut?
Yes, the 150mm motorized lift integrates emergency power-off lifting mechanism. Once power fails unexpectedly, the flask will be automatically separated from heating medium to avoid sample damage from dry heating, this safety feature is unavailable on manual LRE-2L-S.
Will powder suspension samples stick to flask wall and agglomerate at max 280rpm?
20–280rpm clockwise & counterclockwise intermittent alternating rotation continuously stirs materials back and forth, powder & high-solid suspensions will not sediment or form local wall caking during long-time concentration, stirring performance better than LRE-2L-S with 200rpm speed limit.
Is the condenser factory standard or an extra optional accessory?
1700cm² large high-efficiency condenser is fully standard equipped for LRE-2L-Pro with no extra cost; LRE-2L-S provides two sizes (1200/1700cm²) as separate optional upgrades.
Can runtime experimental data be exported to meet compliance lab record standards?
Built-in standard USB communication port logs full raw temperature, speed and runtime data for each batch, records can be exported via U-disk for archiving, local device firmware upgrade via flash drive is also supported to meet GLP traceability requirements.
Can it work directly in overseas 110V labs?
Auto-adaptive 100–120V / 200–240V wide voltage with automatic 50/60Hz frequency detection, no extra transformer required for European, American and Southeast Asian labs.
Does the unit have protection if heating bath runs empty without medium?
Boil-dry auto power-off protection activates when bath contains no water or heat conduction oil; two extra safeguards including 220℃ overheat shutdown and 50℃ high-temperature warning form three-fold interlock to eliminate empty heating hazards.
What is the maximum compatible evaporating flask volume?
Standard compatible with 50–3000mL round-bottom flasks; 3L large flasks can be installed after ordering optional thickened glass shaft accessory.
