Weighing Bottle

Product Code : SCL-LG-11991

The Weighing Bottle is a clear glass laboratory vessel used for weighing, holding, and protecting suitable solid samples during analytical and chemistry procedures. Fitted with a ground glass joint and stopper, it is intended for laboratories requiring controlled sample handling while reducing exposure to moisture, dust, and airborne contamination.

Product Description

The Science Lab Supplies Weighing Bottle is manufactured from clear glass and fitted with a ground glass joint and stopper. The closure provides a sealed environment that helps protect suitable stored contents from moisture, dust, and airborne impurities during laboratory weighing and temporary sample storage.

The product is available in verified sizes of 60 × 30 and 35 × 25; however, the units and dimensional orientation are not stated and should be confirmed before ordering. Buyers can explore related laboratory glassware for wider sample preparation and analytical requirements.

How to Use the Weighing Bottle

1. Inspect the bottle and stopper for cracks, chips, contamination, or damage.
2. Clean and dry the bottle according to the laboratory procedure.
3. Place the empty bottle on a suitable analytical balance and record its mass or tare the balance.
4. Add the required solid sample carefully using an appropriate spatula or transfer tool.
5. Fit the ground glass stopper when sample protection is required.
6. Record the total mass and calculate the net sample mass according to the selected method.
7. Transfer or process the sample as required and clean the bottle promptly after use.

Safety note: Handle glassware carefully and wear appropriate personal protective equipment. Do not use cracked or chipped bottles, and verify chemical and thermal compatibility before exposing the product to aggressive substances or elevated temperatures.

Care & Maintenance

• Clean promptly using a method compatible with the sample and glass construction.
• Keep the ground joint and stopper free from residue to prevent contamination or sticking.
• Avoid sudden temperature changes, impact, and abrasive cleaning tools.
• Store the bottle and its matching stopper together in a protected location.
