It is suitable for the determinations of evaporation residue of food or pharmaceutical packaging, total migration of food contact or pharmaceutical contact materials or products, and evaporation residue of chemical reagents and purified water. This instrument is compliant with test standards:
ISO 1135-4:2015, ISO 1135-5:2015, ISO 3826-1:2019, ISO 3826-4:2015, ISO 8536-4:2019, Pharmacopoeia, YBB00342002-2015, YBB00132002-2015 and other standards for pharmaceutical production and pharmaceutical packaging.
EN1186-3, GB 31604.8-2016, GB/T 5009.60 and other standards for food contact materials.
ISO 759-1981, ISO 6353-1:1982 GM14, GB/T 9740 and other related standards for determination of chemical reagent residue after evaporation.
Equipped with Labthink’s latest fully automatic gripper to realize rapid moving and weighing of 25 test cups. The dual-chamber design realizes separation of evaporation and weighing in separate chambers to avoid the influence of high temperature and high humidity on the scale. There is a high precision electronic scale with a repeatability up to 0.05mg, easily visible through the viewing panel. The scale can be quickly disassembled for maintenance and calibration.
The C840H is safe and compliant with a fully-closed, zero leakage water bath to avoid harmful gas overflow. Water fill and drainage of the water bath are automatic; and the liquid level is automatically detected. A rapid liquid cooling system quickly achieves room temperature weighing. Nitrogen purge cycling and independent electrical control system are safe for tests of flammable, explosive or toxic gases which may be released from test material. Highly efficient reagent collection reduces environmental pollution.
With a 12.1" medical-grade touch screen user interface, the instrument is operated independently without a computer. The instrument mainframe adopts a desktop design to save space. The water bath automatically moves in and out of the chamber and automatically closes the lid for convenient operation. Water bath evaporation, drying, cooling and weighing at room temperature are also completed automatically. The instrument is equipped with various kinds of sensors with sound and light intelligent reminders for operator safety. The instrument is equipped with a network port and can be connected to the Internet for remote control and upgrading. Professional software meets GMP requirements for data traceability and the needs of the pharmaceutical industry. Multi-level operation authority management for users can be configured on demand. Electronic signature is designed as per standard requirements of 21 CFR Part 11.
