Sand Baths

Introduction

Sand baths provide uniform heating using sand as a thermal medium. They are widely used in chemical laboratories. The system ensures stable heating conditions. It solves direct heating inconsistencies. By providing distributed heat transfer, it supports controlled experiments.

Standards

ASTM E2488-09(2014)-Standard Guide for the Preparation and Evaluation of Liquid Baths Used for Temperature Calibration by Comparison

Complies with the above standards, but is not limited to them.

Features

1. Sand bath providing uniform and controlled heating of samples and vessels.

2. Sand medium distributes heat evenly across the working surface.

3. Precise temperature control with digital display for reproducible results.

4. Durable construction suitable for laboratory heating applications.

5. Suitable for digestion, evaporation, incubation and general heating tasks.

FAQ

Q1: What is the sand bath mainly used for?

A: It is used in chemistry and biology laboratories to heat beakers, flasks and samples uniformly using sand as the heat-transfer medium. Sand baths are commonly used for digestion, evaporation, incubation and heating operations requiring gentle, even heating.

Q2: What standards does the sand bath comply with?

A: The unit is designed with reference to IEC 61010 electrical safety requirements and relevant GB/T standards for laboratory heating equipment. Application procedures should follow the applicable standard methods. Compliance documentation can be provided on request.

Q3: What is the warranty period for the sand bath and key components?

A: The complete unit carries a 12-month warranty covering the heating system and controller. Sand and accessories are excluded. Damage from improper use or unauthorised repair is not covered.

Q4: Is the sand bath difficult to operate?

A: Operation is simple: set the temperature and place the vessel in the sand. No special training is required. The manual explains sand level, temperature setting and maintenance, and remote guidance is available.

Q5: What is the typical lead time for order delivery?

A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Q6: Does the sand bath require calibration or verification?

A: Temperature should be verified periodically against a calibrated reference thermometer, typically every 6 to 12 months. The unit is factory tested before delivery. Optional calibration service can be arranged.

Q7: Are consumables or spare parts universal?

A: Sand and standard spare parts are available through our channel. No proprietary consumables are required. Provide the model and serial number when ordering.

Q8: Can the sand bath be customised?

A: Yes, options include different working surface sizes, temperature ranges, 220V or 110V supply and digital timers. We confirm each option before order confirmation.

Q9: Is installation and commissioning included?

A: The unit is commissioned by following the manual, including sand filling, electrical checks and a temperature test. Remote guidance is available during commissioning. On-site installation can be arranged separately.

Q10: What materials should not be heated in the sand bath?

A: Flammable solvents above their flash point and materials that react dangerously at high temperature should not be heated without appropriate precautions. Use heat-resistant vessels and follow laboratory safety regulations.
