It enables exact specific gravity measurements of liquids, powders, and particulates by mass comparison, supporting applications across industrial, educational, and research settings. Its robust thermal resistance and detailed calibration protocol ensure reliable, repeatable results that meet professional standards. ## Description Warranty! If received damaged, please contact us immediately. We will solve it until satisfied. 1. This is a device that accurately measures the volume of a glass or metal container. The known volume of the pycnometer can be used to determine the density of the powder, liquid, and particulate. Temperature range: 0~40°C, temperature index value: 0.5°C. 2. It is suitable for measuring the liquid density in industrial, laboratory, school, agricultural grain and other units, and analyzing the purity, volatile energy or content of the substance. 3. Warranty! If received damaged, please contact us immediately. We will solve it until satisfied. 4. Made of High borosilicate glass and has a very low thermal expansion coefficient, about one third of ordinary glass. High temperature resistance and temperature difference of 200 degrees. 5. Before use, the temperature thermometer, empty bottle weight and water weight should be strictly calibrated according to the requirements, and the requirements can be used. Instructions: 1. Wash the pycnometer and bake it, and record its quality. 2. Put the sample into the bottle to the mouth of the bottle, and transfer it to a constant temperature water bath at 25 °C (the temperature difference does not exceed 1 °C) soak 10-20mn. 3. When the sample reaches this temperature, insert the stopper to allow excess liquid to flow out of the capillary. 4. Wipe the net with a filter paper. Do not touch the pycnometer by hand during wiping to avoid excessive overflow of the solution. 5. After wiping, transfer it to the balance and weigh the mass and then deduct the quality of the bottle, which is the quality of the sample. 6. Make a note of the above temperature conditions and operating procedure Review: Calidad igual a la foto - Muy bueno duro en llegar pero llego bien Review: essential for determining liquid densities. - Product is used to determine densities of liquids such as water and mineral oil. ## Features - This is a device that accurately measures the volume of a glass or metal container. - It can measure the volume defined by the density and volume of the liquid by simple weighing. - The known volume of the pycnometer can be used to determine the density of the powder, liquid, and particulate. - Place in a constant temperature water bath and maintain a constant temperature t. The mass of the pycnometer itself is ω, the total mass is W when filled with pure water, and the total mass when filling the liquid to be measured is W'. Then, the specific gravity dL of the liquid is: dL = (W' - ω) / (W - ω). - Temperature range: 0~40°C, temperature index value: 0.5°C. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.5 out of 5 stars 3 Reviews | ## Images ![25ml 50ml with Thermometer Lab Glass Specific Gravity Bottle Pycnometer Class A (50ML) - Image 1](https://m.media-amazon.com/images/I/51nWVVkHgML.jpg) ![25ml 50ml with Thermometer Lab Glass Specific Gravity Bottle Pycnometer Class A (50ML) - Image 2](https://m.media-amazon.com/images/I/51QKwqwb31L.jpg) ![25ml 50ml with Thermometer Lab Glass Specific Gravity Bottle Pycnometer Class A (50ML) - Image 3](https://m.media-amazon.com/images/I/51TsteLrkdL.jpg) ![25ml 50ml with Thermometer Lab Glass Specific Gravity Bottle Pycnometer Class A (50ML) - Image 4](https://m.media-amazon.com/images/I/61zN4DBl0GL.jpg) ![25ml 50ml with Thermometer Lab Glass Specific Gravity Bottle Pycnometer Class A (50ML) - Image 5](https://m.media-amazon.com/images/I/5175Z422e8L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Calidad igual a la foto *by Y***O on September 28, 2024* Muy bueno duro en llegar pero llego bien ### ⭐⭐⭐⭐ essential for determining liquid densities. *by C***S on December 30, 2024* Product is used to determine densities of liquids such as water and mineral oil. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/190212486-25ml-50ml-with-thermometer-lab-glass-specific-gravity-bottle-pycnometer](https://www.desertcart.co.th/products/190212486-25ml-50ml-with-thermometer-lab-glass-specific-gravity-bottle-pycnometer) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-07-09*
