Laboy Glass Thermometer Inlet Adapter - 24/40 Inner Joint Apparatus for Chemistry Lab Glassware

The laboy glass thermometer adapters have a standard taper ground male joint at one end while the other end is an open top compression cap ideal for fitting a plain stemmed thermometer into jointed glassware assemblies in organic chemistry. A vacuum-tight seal is created with the open top compression cap and o-ring to allow adjustable immersion of thermometers or bleeding tubes; Cap is suitable for use to 150 °C. The ground glass joints allow the laboratory glassware to be assembled, leak-free, without stoppers. This laboratory glass thermometer adapter is made of high quality borosilicate glass 3. 3 having very low coefficients of thermal expansion for resistance to heat, and a very high resistance to chemical attack. Laboy glass ware are all made of high quality boroslicate glass and annealed at 800 degree Celsius , can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling. The ground joints are precisely grounded according to US standard. With 14/20 Interchangable standard taper inner joint which can be fit for any apparatus with standard outer joint. The hole on the compression cap accommodates 5.0-7.5mm O.D.thermomter or bleed tube as a syringe port. With 19/22 Interchangable standard taper inner joint which can be fit for any apparatus with standard outer joint. The hole on the compression cap accommodates 5.0-7.5mm O.D.thermomter or bleed tube as a syringe port. With 24/40 Interchangable standard taper inner joint which can be fit for any apparatus with standard outer joint. The hole on the compression cap accommodates 5.0-7.5mm O.D.thermomter or bleed tube as a syringe port. With 29/42 Interchangable standard taper inner joint which can be fit for any apparatus with standard outer joint. The hole on the compression cap accommodates 5.0-7.5mm O.D.thermomter or bleed tube as a syringe port. Standard Taper Ground Glass Joints are interchangable.For either frosted, presicon-ground standard taper joints (same size),the inner ground surfaces (male joint) make a good seal with the outer(female joint)). The joint size is described by the form A/B. The first number A represents the outer diameter (OD) in millimeters (mm) at the widest point of the inner (male) joint and the second number B represents the length of the joint. For example, a 14/20 joint is 14 mm wide at the top (the widest part) and is 20 mm in longth. The joint has a standard taper 1:10, any two joints (male and female) with the same outside diameter (A)can fit into each other ,no matther how lenght the joints are. For example, a 24/40 (US standard size) joint on a condenser will fit into a 24/29 (European standard size)flask but the ground glass joint will protrude (40 - 29) 11mm into the flask. Laboy glass ware are all made of high quality boroslicate glass according to ASTM E438,heavy wall design,durable and reusable.
