Jeio Tech | Heating Bath Circulators General | High Temperature Circulating Water Bath with ID Control, Variable Speed Pump and USB Data Monitoring
The Jeio Tech General Type Circulating Bath, available at Alto Med Supply, is designed for reliable and precise temperature control in laboratory and research applications.
Built with advanced microprocessor PID control technology, this laboratory bath delivers accurate and stable temperature performance while supporting both internal and external circulation.
Its compact design helps save valuable bench space, while the durable stainless steel construction provides excellent corrosion resistance and easy cleaning for long-term use.
This high-performance circulating bath is equipped with a clear VFD display for easy monitoring and simple operation.
Users can quickly adjust settings, save up to three frequently used temperatures, and utilize the convenient wait on/off timer for improved workflow efficiency.
The built-in USB connection and dedicated software allow for remote control and data management, making it ideal for modern laboratory environments that require dependable monitoring and operation.
Designed with user convenience in mind, the unit features a front drain valve for easy bath fluid removal, integrated body handles for smooth transport, and a low-heat conductivity bath cover that helps reduce evaporation at high temperatures.
The adjustable 5-step pump speed system allows users to optimize circulation performance based on application requirements, while rubber feet provide added stability during operation.
Safety is a key feature of the Jeio Tech General Type Circulating Bath.
The system includes advanced overheating protection, over-temperature limiting functions, low-level solution alerts, and temperature sensor abnormality notifications.
In the event of an error, the system displays detailed alerts on the screen and activates an audible alarm for added protection.
The heater, sensor, and pump are separated by protective covering plates to minimize direct contact and improve operational safety.
For enhanced reliability, the bath supports three-point temperature calibration, automatic tuning, and automatic restart after power restoration.
Users can also expand monitoring capabilities through the optional LC Green Box mobile monitoring system, allowing remote access and monitoring through the LC Connected mobile app anytime and anywhere.

Outdoor Wheelchair for Recreation
I bought this wheelchair to be used outside to help me get to and from our pool and hot tub. It works great.

Great Service. Good Purchase.
I think that I received the Rollz Electric a day or two after ordering. Great service!
First outing was an overnight at Disneyland. As with all wheelchairs, this chair will take some getting used to. As my husband's caregiver, I use the electric drive-assist function as I push the chair. It definitely makes pushing easier. There is a learning curve. Whenever you take your hand off the chair handles for 5 seconds, you get an error message and have to reset to continue. This could be improved. The back wheels are (naturally) wider than the non-electric Rollz Motion chair, and that takes getting used to maneuvering through doorways and tight spaces. We are having a Surelift 88 installed in the back of our Prius because at around 60 lbs, the Rollz Electric is too heavy for me to lift. Overall, I'm happy with the purchase.

Outstanding product and service by office liaison Jean
The Nano lift arrived in excellent condition. We were impressed with the quality of engineering and manufacturing that went into this product ( I had a metal fabricating shop so I can appreciate quality and precision).My friends, an electrician and carpenter and I installed it in less than a day. I would like to point out that the installation instructions were poor and could use much improvement. We had to refer to the bar code for special videos on many items. Many of these referenced the Hercules lift and not the Nano. My thanks to your office liaison JEAN who did an outstanding job getting us thru the purchase and transport issues we had.THANK YOU JEAN. Yours truly Fred Roesslein
