数字振荡器，带微处理器控制，适用于一系列混合应用，如细胞培养、溶解度研究和萃取程序。可变速度控制提供了持续一致的振荡动作。Accu驱动振荡系统具有卓越的速度控制、精度、安全性和耐久性，可以持续监控振动速度，并即使在载荷变化的情况下，仍能保持设定点操作。

• Two independent LED displays show speed and time
• Integral timer, 1 s to 160 h, shows elapsed time or counts down, automatic switch off and audible alarm when program is complete
• Can be used at −10 to +60 °C (max. 80% relative humidity, non condensing), in an incubator, CO₂ incubator or cold room

实际速度与设定速度之间的精度达1%。变速功能能够缓慢地将速度提升至所需设定点，增强安全性。内置载荷传感器可以检测失衡情况，并自动减少min^-1至安全速度，以防止溅泼，保护样品。通过速度校准模式，用户可以重新校准速度显示，而RS232串口则为数据记录和装置控制提供了双向通信模式。

VWR® Advanced Orbital Shaker, Model 3500

• 15.9 kg (35 lb.) Capacity
• Exclusive Accu-Drive™ Shaking System
• Now with Best in Class, Exclusive 5-Year Warranty

Digital orbital shakers are designed for a wide range of applications such as solubility studies, extraction procedures, and cell cultures that require accurate and reproducible results. Distinctive operational features include the exclusive Accu-Drive™ Shaking System, which delivers exceptional speed control, accuracy, and durability. The system continuously monitors shaking speed and maintains set point even under changing loads. Displayed speed is accurate to 1% of setting. The variable speed microprocessor control provides consistent, uniform mixing action. Microprocessor will display last set point and will restart if power is interrupted. The shaker's powerful triple eccentric drive and brushless motor ensure reliable service in continuous duty and can handle loads up to 15.9kg (35lbs.). 
 

Shakers are equipped with touchpad controls with easy-to-read, independent LEDs for speed and time, allowing users to view all settings simultaneously. Timer will display elapsed time or, when programmed to user-defined limit, will shut off the unit. Display will show last settings even after power is turned off. A built-in load sensor detects unbalanced conditions and automatically reduces rpm to a safe speed, or stops the system entirely. The microprocessor's ramping feature slowly increases speed to the desired set point to avoid splashing or sample loss. Shakers can be run in cold rooms, incubators, and CO₂ environments from –10 to 60°C (14 to 140°F). An audible alarm will sound in timed mode when timer reaches zero. Two-way communication for data logging and unit control is provided by an RS-232 serial port. 
 

Shakers can accommodate a variety of stainless steel platform options. Tier braces are constructed of stainless steel, allow stacking of same sized platforms, and provide a 25.4cm (10") clearance between platforms. Adjustable platforms are equipped with 4 adjustable cushioned rollers to hold most glassware securely. Universal platforms are suitable for mounting flask clamps and test tube racks. The culture platforms with mat are ideal for slow speed applications that utilize low profile vessels such as petri dishes or culture flasks. The separatory funnel platform holds up to three 500mL–2L samples at once. Dedicated platforms feature pre-mounted PVC flask clamps for maximum utilization of space. Flask clamps are available in either stainless steel or PVC styles. Media bottle clamps and microplate clamps are constructed of stainless steel. Pivoting test tube racks feature stainless steel construction. Standard test tube racks feature a PVC-coated steel construction. Both rack styles come with hardware for easy attachment to platforms. 
 

Ordering Information: Shakers are supplied with a nonskid rubber mat that fits the 33x28cm (13x11") tray. Tray is suitable for holding petri dishes and cell culture flasks. Unit also includes a 2.3m (92") detachable 3-wire cord and plug. All platform, clamp, and rack accessories are sold separately. 230V, 50/60Hz models are also available; contact your VWR sales representative for more information.
