Memmert water bath WTB11, 10 L, touch display, +100 °C

The Memmert water bath WTB11 belongs to Memmert's new water bath generation.

The Memmert water bath WTB11 reliably brings samples and reagents to a constant temperature between +10 and +100 °C. At 10 litres, it offers a bit more room than the WTB6 without taking up the bench space of a larger bath.

New model generation

The WTB11 is part of the full relaunch of the Memmert water bath range for price list 01-2027, which replaces the previous model line entirely. Accessories such as lids, base grids, insert racks and test tube racks now come with new order numbers. There is no pump module for the WTB11; this factory option is reserved for the WTB15 and larger models. When reordering accessories, it is worth checking the current order number, listed further down in this description.

Touch display and controls

Controls run through a 3.5-inch colour graphic touch display with 2-point calibration and the customisable remote screen “CustomView”. Target and actual temperature can be set and read with an accuracy of 0.1 °C. The display shows the key operating values at a glance without needing a separate control panel.

Stainless steel tank and cleaning

As with the rest of the range, the tank is deep-drawn stainless steel 1.4301, without corners or edges, with a central drain system for cleaning. The heater sits outside the chamber; the housing is also stainless steel. Four adjustable feet compensate for an uneven bench. That makes daily cleaning and disinfection between two different batches easier.

Connection and operation

The connected load is 1,000 W at both 230 V and 115 V (50/60 Hz). The 115 V version is available as option X2 at no extra cost. A standard lab socket is enough; no dedicated high-current connection is needed.

Size within the WTB range

At 10 litres, the WTB11 is the second-smallest model in the range, between the smaller WTB6 and the WTB15. Controls, material and drain system are identical across the whole range; the main differences are internal dimensions, capacity, weight and, from the WTB15 upward, whether the pump module P7 is available.

Footprint and transport

Internal dimensions are 310 x 190 x 220 mm, external with the flat lid 407 x 317 x 342 mm, with the sloped lid 407 x 317 x 444 mm. Packed dimensions are 500 x 450 x 495 mm, gross weight is 16 kg, net weight 13 kg. The footprint matches the WTB6, only the internal width is larger.

Calibration and documentation

A factory calibration certificate is not part of the standard equipment and is not included in the scope of delivery. Anyone who needs documented calibration, for example for a quality management system according to ISO 9001 or for test equipment monitoring, can order it as an additional chargeable service through our procurement service. That way the initial commissioning can be documented without having to ship the unit off separately.

Typical applications

With a setting range of +10 to +100 °C, the WTB11 covers a wide range of tempering tasks in the lab. Here too, the water surface stays calm without a pump, useful for samples that should not be disturbed.

• Tempering samples and reagents at a constant +10 to +100 °C
• Thawing and warming several smaller vessels side by side
• Routine tasks in chemistry, microbiology and quality assurance labs with moderate sample throughput
• Use as a second water bath alongside a larger unit for parallel batches at different temperatures

For everyday routine work with a manageable number of vessels, the WTB11 is usually enough. If a full test tube rack is needed regularly, the WTB15 with its extra internal length is the better fit within the same range.
