Pour Point, Cloud Point, Freeze Point, and Cold Filter Plugging Point (CFPP) of Petroleum Products – ASTM D97, D2500, D5853, D6371, D6422 | IP 15, IP 16, IP 219, IP 309, IP 441 | ISO 3015, ISO 3016 | DIN 51597| EN 116, EN 23015 | NF T 60-105 | FTM 791 201 | JIS K 2269
The DR6 and DR7 series are fully automated cold property analyzers. It is the latest version of the DR4 and DR5 series. They can test either cloud and pour point, CFPP, or freeze point. The DR6 and DR7 series has a state-of-the-art cooling system that allows a wide temperature range from -120°C to +35°C. It cools at a rate of 1° C in 5 seconds or less. It maintains temperature of +- 1°C.
The DR6 and DR7 series are nearly identical in design and configuration. The only difference is the number of test positions. The DR6 is a single test position instruments, while the DR7 series signifies dual test positions.
All DR6 and DR7 instruments come fully loaded with all necessary accessories ready to run at full capacity out of box.
- Low consumption.
- Only 12 inches wide
- High resolution, tablet-style touchscreen.
- Fully contained, maintenance-free refrigeration system.
- Easily export test data to LIMS, or flash drive.
- Print tests from machine.
- Cloud and Pour Point is analyzed in one test position
- Software logs complete testing history
In addition to standard tests, the machine can be set to maintain a certain temperature, which is convenient for various lab activities.
Model OL series are designed to work with an external alcohol chiller, either your own or supplied by Lawler. OL series units are available in 1 or 2 test positions. Lawler offers two recirculating chiller models (MRCC-80 and MRCC-5) for use in conjunction with the OL analyzer.
A wide range of models is available with working temperature ranges from +48° to -69°C. Each multi-bath unit conforms to ASTM D97 Pour Point and ASTM D2500 Cloud Point test methods and related methods. Each stainless steel liquid bath has its own digital indicating PID temperature controller with 0.1°C resolution, providing temperature stability of ±1.5°C. The baths of select models are agitated for improved temperature stabily (±0.5°C) and uniformity and are, therefore, suitable for ASTM D6371 (or IP309) cold filter plugging point test with the addition of the CFPP kit. Each bath comes equipped with 4 metal test jackets, 4 cork rings, 4 O-rings, and 4 cork stoppers for the thermometer (test tube is available separately). All units are mechanically refrigerated using ozone friendly non-CFC and non-HCFC refrigerants.
Model 334 is the most popular and versatile 3 bath bench model is the “work horse” of the industry. The baths are factory preset at 0°, -18°, and -33°C. Each bath has 4 test sample capacity. The approximate overall dimensions are 25 x 19 x 26 inches high (62 x 48 x 65 cm).
Model 644 is also a popular caster mounted, floor model with 4 baths factory preset at 0°, -18°, -33°, and -51°C. Each bath is mechanically agitated for improved bath temperature uniformity and control. Each bath has 4 test sample capacity. Approximate overall dimensions are 37 x 31 x 43 inches high (94 x 78 x 110 cm.)
Model 654 is a caster mounted floor model with 5 baths factory preset at 0°, -18°, -33°, -51°, -69°C. Each bath is mechanically agitated for temperature stability of ±0.5°C.
Model DR-2L with two test positions is a portable, unique cloud and pour point bath, not using any liquid as the cooling medium. It has the ability to very rapidly (less than 2 minutes) change the metal cup temperature to the next lower temperature. This allows one bath to perform the pour and cloud point as well as CFPP tests without the need to move the test tube to the next lowest bath temperature. Each cup has its own digital temperature controller and their temperature may be set independently. Lowest bath temperature is -69°C.
Model DR-1H/L is similar to Model DR-2L and is an economical, compact single test position bath with lowest bath temperature of -33°C. It is an ideal bath for mobile fuel testing laboratories. Overall dimensions are 22 x 18 x 33 inches high (55 x 45 x 83 cm).
