Product Weight (lbs): 0.6

side opening for up to 3 neck 250ml spherical flask for aluminum housed mantle, 140W, 230V Flask Diameter: 83 mm

Preventing Vapor Condensation In the Upper Half Of a Flask During Distillation Of High Boiling Materials. Supplied With a 4 Foot 2-Wire Twist-Lock Cord. Tops Are Designed To Work With Series M, TM, O, and STM Mantles. They Also Can accommodate Up to a 3-Neck Flask.

This mantle helps prevent vapor condensation in the upper half of a flask during distillation of high-boiling materials.

They protect the flask, the solutions, and the laboratory in these ways: 

1) from drafts, which would disturb the reflux ratio during fractionation;

2) from flying glass of flask implosions in high-vacuum distillations; 

3) from falling objects; 

and, 4) from thermal strain between top and lower half of flask during hightemperature operations. With a glass-fabric construction and laced-side opening, the

elliptical hole accommodates 1-, 2-, and 3-neck flasks.

Specifications

Electrical: Separable 4-ft., 2-wire cord and locking connector.

侧面开口，最多可容纳3个颈部250ml球形烧瓶，用于铝制外壳，140W，230V烧瓶直径：83 mm

防止高沸点物质蒸馏过程中烧瓶上半部分的蒸汽凝结。随附4英尺2线扭锁线。上衣经过设计可与M，TM，O和STM系列衬套配合使用。它们还可以容纳3颈烧瓶。

该罩有助于防止高沸点物料蒸馏过程中烧瓶上半部的蒸汽凝结。

它们通过以下方式保护烧瓶，溶液和实验室：

1）从气流中分馏，这会影响分馏过程中的回流比；

2）在高真空蒸馏中从烧瓶内壁飞出的玻璃中取出；

3）掉落的物体；

4）由于在高温操作期间烧瓶的上半部和下半部之间的热应变。具有玻璃纤维结构和侧边开口，

椭圆孔可容纳1颈，2颈和3颈烧瓶。

规格

电气：可分离的4英尺2线软线和锁定连接器。
