This laboratory water bath is a digital thermostatic bath with a stainless steel tank and PID temperature control from room temperature to 99.9°C. It comes in 1, 2, 4 and 6 hole sizes, from 400W to 1000W, and suits warming, drying, concentrating and distillation work on the bench.
Features and benefits:
- PID control with 0.1°C resolution: the set temperature is held steady, with a measurement error of ±0.2%FS or ±0.5%FS
- Dual LED display: temperature and heating time are both shown on the red control panel, and the timer can be set from 0 to 999 minutes
- 304 stainless steel inner liner with a moulded, weld-free tank: no seam for scale or residue to collect in
- Built-in stainless steel heating tube with 360° cycle heating
- PP ring lids: the ring cap adjusts to different sizes of flask and beaker
- Plug-out drain pipe and a power switch: emptying and shutting down are straightforward
- P models add dry-burn protection, timed heating and an overtemperature alarm; the standard models do not have the dry-burn function
Applications:
- Warming and incubating samples in laboratory and school science work
- Distillation, drying and concentrating
- Holding flasks and beakers at a steady temperature in workshops, food, cosmetics and brewing tests
Note: Keep the water level high enough and never let the heating element run in air. Prevent hot water splashing, and keep the bath dry around the controls. Clean after use to avoid scale and residue. Use a thermometer to check the temperature when accuracy matters. Choose the plug type for your mains supply; the UK shop plug options are listed in the options.

A: A water bath holds samples, flasks and beakers at a steady, gentle temperature. This one is used for warming, drying, concentrating and distillation, from room temperature to 99.9°C.. Q: How do you use a water bath in a laboratory? A: Fill the tank with water to a safe level, switch on and set the temperature with the buttons. Place the flasks or beakers in the lid holes once the display shows the set value, and set the timer if needed.. Q: What is the difference between the HWB and HWB-P models? A: The P models add dry-burn protection, timed heating and an overtemperature alarm. The standard HWB models do not have the dry-burn function.. Q: Which size of water bath should I choose? A: Pick by the number of holes: 1 hole at 400W, 2 holes at 600W, 4 holes at 800W or 6 holes at 1000W. The inner sizes are 160 x 160 x 140mm up to 470 x 305 x 140mm.. Q: How accurate is the temperature control? A: The PID controller works to 0.1°C resolution, with a measurement error of ±0.2%FS or ±0.5%FS. The reading can be adjusted by -4.9°C to +4.9°C.. Q: Can the water bath be used with different flask sizes? A: Yes, the PP ring lids are adjustable to different sizes of labware, so flasks and beakers of varying size can sit in the openings..
