INTRODUCTION
The rotary evaporator forms membrane under the negative pressure and constant-temperature heating with rotating, vaporizing efficiently; then receiving solution by condenser. It can prevent bubbling over. The improved ones can abstract recycled. It is the ideal instrument for biology, pharmacy, chemistry and foodstuff lines used for concentrating, desiccating, reclaiming or crystallizing the solution.
SALIENT FEATURES:
1.Frequency modulated speeder，rotating speed displayed digitally.
2.Keeping vacuum with advanced Patented Teflon. Sealing Unit ( Patented No. 022640703 ), withstanding various organic solutions.
3.Designed for running at 180 ℃ permanently.
4.The Patented wye distributor with the ball and socketjoint may run continuously or separating the solutions of two different kinds. Teflon charging valve to with stand wearing and tearing; Teflon outlet valve with advanced sealing.
5.Electromotive rising or reducing the bath，sparkless，flame-proof.
