What is a Wet Bath and What is It Used For?
Water baths, or wet baths, consist of a stainless steel basin filled with heated water and equipped with a digital controller. Water baths are used for sample thawing, reagent warming, substrate melting, coliform determinations, and bacteriological assays by clinical labs, academic research facilities, environmental testing laboratories, and food product quality control testers.
水浴实验室使用和应用程序
Water baths are manufactured in four principal designs: static baths for reagent warming, shaking baths for cell culture and hybridization, stirring baths for substrate melting, and circulating baths for enzymatic assays.
What's the Difference Between a Wet Bath and Dry Bath?
Water baths (wet baths) offer several advantages overdry baths with block heaters。水浴锅容纳任何适合的sample container, including troughs, buckets, and high-capacity culture tubes. Unlike dry baths with fixed block inserts, wet baths provide the flexibility to store different-sized tubes concurrently. As water baths provide a larger surface area than dry blocks, samples are heated in a shorter duration of time. Since water baths store more heat than dry baths, temperature fluctuations are reduced. Wet baths, however, are more prone to water-borne contamination, so the basin must be disinfected regularly to prevent bacterial growth.
A - Water Bath Maximum Temperature

Standard water baths将温度从5°C保持在环境温度至100°C。没有外部加热设备，水浴不能达到高于100°C的温度。随着水是热的优异导体，湿浴在整个盆地中保持高度的温度均匀性（耐受降至0.2℃的耐受性。数字LED控制器提供浴室条件的实时读数，并在温度超过用户选择的设定点时触发可听警报。

B - Laboratory Water Bath Tank Capacity
(back to chart)
The tank capacity is the volume of water, or thermal beads, safely held within the water bath’s steel basin. Low-throughput baths hold 2 liters of fluid while high-throughput baths hold up to 12 liters of fluid. Certain models offer included or optional sample racks or tube blocks to maximize the storage capacity of the bath.

C - 最大水浴摇动速度
(back to chart)
Shaking water bathsare optimal for cell culture, hybridizations assays and environmental sample testing. The water bath shakes the basin in an orbital motion to promote mixing of bacterial samples, cell media or reagents during thawing or warming procedures. Low-speed baths maintain shaking speeds of 200 rpm for samples diluted in PH-neutral buffer or DI water. High-speed baths maintain shaking speeds of 500 rpm for viscous reagents or cell growth media.
D - Voltage

D1 - 120V水浴
120伏连接适用于美国的标准住宅电源插座。
D2 - 240V水浴
24.0-volt connections require less current (amperage) and smaller conductors than appliances designed to operate at 120V.
E - Application-Specific Water Bath Features

E1 - 水浴样品架
Certain models offer included or optional sample racks configured to maximize storage of 2.0 ml flip-cap tubes, 15 ml centrifuge tubes, or 50 ml culture tubes.
E2 - 带排水口的水浴
Drain ports support easy cleaning of the basin, simplify fluid refills, and protect the work area from water spills. For baths located away from sinks or liquid waste containers, optional tubing connects to the drain port for easy fluid disposal.
E3 - Water Baths with Gable Cover
清除山墙盖保护来自外部污染物的样品，容纳不同尺寸的玻璃器皿和管，简化样品载荷，防止凝结积聚并抑制热逸出。
E4 - Water Baths with Self-Calibration
Benchmark’smyBathandBeadBath Duo包括Quick-Cal编程，以定义用户选择或自动温度校准。每月或季度温度校准确保浴室根据规范进行。
E5 - 带数字显示的水浴
Digital controllers include real-time LED readouts of bath conditions, audible alarms if the temperature exceeds the user-defined set point range, and over-temperature controls to protect samples from overheating. Certaindigital controllers allow users to define and save programs for quick recall。
E6 - Thermal Beads for Wet Baths
Thermal beads are dry metal beads used in non-shaking, static wet baths as an alternative to water. As compared with water or bath fluid, thermal beads are more resistant to bacterial growth, but less effective in achieving temperature uniformity. For samples prone to cross contamination, thermal beads are often used instead of water.
