Compact Cloud and Pour Point Bath

A compact cloud and pour point bath built for extreme low-temperature manual testingThe K66100 Manual Compact Cloud and Pour Point Bath is a cloud and pour point bath designed for the precise manual determination of cloud point and pour point for petroleum products, fuels, lubricants, and crude oils.
It is positioned as a space-saving, solid-block bath, providing standards-compliant testing performance where bench space is limited.For laboratories running routine and investigative cloud and pour point test work, the K66100 focuses on practical outcomes that matter at the bench: controlled step temperatures, rapid stage transitions to key low-temperature points, and reduced ice-related interruptions.ASTM method alignment (ASTM D97 / ASTM D2500 / ASTM D5853) with related IP stepsThe K66100 conforms to ASTM D2500 (Cloud Point), ASTM D97 (Pour Point) and ASTM D5853, and it is also listed as conforming to related IP methods IP 15, IP 441 and IP 219.
This makes it suitable for laboratories that need a manual ASTM D97 bath workflow and an ASTM D2500 cloud point bath arrangement in a compact footprint.Extreme low temperature capability with controlled reheatingA key requirement in cold-flow testing is stable operation at very low temperatures. The K66100 is specified with a temperature range of -105 to +6°C, and it includes a reheat to 24°C capability.
The datasheet also states that the jacket temperature can reach down to -105°C, supporting extreme low temperature testing needs for fuels and lubricants.Pre-set temperature steps to support consistent stage-based testingTo support repeatable manual stage progression, the K66100 provides pre-set temperature steps for cloud and pour point specifications.
The listed CPP temperature steps (°C) are: 6, 0, -18, -33, -51, -69, -87, -105.
For CFPP the listed steps (°C) are: 0, -17, -34, -51, -67, -85.2.
This helps laboratories maintain consistent stage temperatures during a cloud and pour point workflow without relying on external step programming.Fast step transitions aligned to method expectations down to -51°CThroughput and workflow consistency often hinge on how quickly a bath transitions between stages. The K66100 is specified to meet step transition time requirements of five minutes or less per step down to -51°C, stated as meeting step transition time to the automatic method requirement.
This supports efficient movement through key stages without extended waiting periods, while keeping the simplicity of a manual bath approach.Solid-block design and ice control to reduce routine disruptionsThe Petro‑Online article describes the solid-block bath design as minimising temperature gradients and improving reliability in routine use.
The datasheet also explicitly states “No ice building on the top cover”, and the article highlights elimination of ice build-up on the top cover to reduce routine maintenance.
For day-to-day testing, this focus on ice control can reduce interruptions that typically slow manual cold-flow work.Turnkey configuration supplied with four test assembliesThe K66100 is supplied as a turnkey solution and includes four complete cloud and pour point test tube assemblies, supporting quicker commissioning and fewer gaps at installation.
Included assemblies are specified as: K77000-2 Pour Point Test Vessel, K77000-03177 Cork, K66100-11 Cloud and Pour Point Head, and 504-000-024 O-Ring.Practical installation details for lab planningFor lab utilities, the K66100 specifies 90–264V, 47–63Hz, 2.5A max, which supports common laboratory power supply ranges.
Its physical dimensions are 30.5 cm × 27 cm × 48.5 cm, with a weight of 16 kg, making it suitable for bench-top integration in space-limited environments.
