The Water Bath Sample Concentration consists of a base and supporting assembly, sample holder and gas distribution system. Test tubes are placed by a spring-loaded sample holder and support tray. The gas passes through the flow meter to the distribution system. Flexible tubing leads gas to valve-tube assemblies at each position. Depending on the test-tube size and solvent volume, they can be individually raised or lowered to the correct height. Needles blow gas onto the surface of the solution resulting in rapid evaporation of the solvent.

Never Miss a Mail Again: Introducing the Smart Mailbox Alert Tired of missing important letters or packages because you didn’t notice the mailbox was opened? The Smart Mailbox Alert is here to solve that hassle—your new go-to tool for effortless mail management. How It Works (Simple & Effective) This device pairs a transmitter (mounted on your mailbox) with a receiver (kept indoors). The moment your mailbox door opens, the transmitter sends a wireless signal to the receiver, which instantly triggers sound and light alerts (the light stays on until you press the reset button). No more guessing if mail has arrived—you’ll know the second it does. Key Features That Impress 3 Customizable Alert Tones: Long-press the receiver’s button to switch between 3 voice reminders (say goodbye to generic beeps!). Remote Notification: If you’re out, the receiver flashes orange to flag new mail—no more coming home to unopened letters. All-Weather Reliability: IP55 waterproof rating means it works flawlessly in rain, snow, or extreme temperatures (-20°C to 55°C). Long-Range Connectivity: It supports a 250m (800ft) wireless range in open air—perfect for large yards or multi-story homes. Easy Setup & Power Options: Install the transmitter in minutes; the receiver runs on USB (DC 5V) or 3 AAA batteries (backup), while the transmitter uses a 12V alkaline battery.
